Metroid franchise strategy guide/Creatures in the Metroid series

This page is intended to be a master list and information base for all Metroid series species. Except for articles on major characters, like Samus Aran, the Chozo, and Ridley, most individual pages about such creatures should redirect to here. If such pages do not, please help by merging their content onto this page and redirecting them.

This is a list of Metroid series species, organized by first appearance.

Major characters



A young Samus and an elderly Chozo from Metroid: Zero Mission.

The Chozo are an anthropomorphic species of bird-like creatures, known to be of very great intelligence. Chozo scientists were the ones who designed Samus Aran's Power Suit.



Samus Aran


The female protagonist, equipped with a Chozo-made Power Suit and known as the best bounty hunter in the galaxy. She was orphaned at a young age by Ridley and adopted by the Chozo.

Galactic Federation Troopers


These troopers wear power suits similar to MJOLNIR battle armor and are the infantry of the Galactic Federation. They appear as enemies in Metroid Prime 2: Echoes when an entire crew is possessed by the Ing.

Metroids are a fictional species of alien predators and the series's namesake, originating from the fictional planet SR-388. Metroids feed on the "life energy" of their prey in a manner similar to leeches draining a host organism's blood. However, Metroids normally drain enough energy to kill their victims. According to the Metroid Fusion instruction manual, the Metroids were created by the Chozo to stem the spread of the X Parasites and "Metroid" is the Chozo word for "ultimate warrior".

Space Pirates


This alien race specializes in raiding starships and planets in a quest for dominance in the galaxy.



Kraid is a large, reptilitan creature which can shoot nail projectiles from his fingers and thorns from his stomach. He is one of the Space Pirate leaders along with Ridley and Mother Brain.



Ridley is an European dragon-like creature that is one of the Space Pirate leaders, along with Kraid and Mother Brain.



Also misspelled Desgeega, the Dessgeega is a side-hopping creature found in parts of Norfair in both Metroid, Super Metroid, and Metroid: Zero Mission. An X Parasite mimicry of the dessgeega (which can now shoot thorns from both sides) can be found in the TRO (tropical) sector of the Biologic Space Labs of Metroid Fusion. The Dessgeega is also the creature within an observation chamber you find on the Space Pirate Frigate, Orpheon in the intro of Metroid Prime. When passing nearby it's chamber, it will violently damage it's door trying to escape. It can be scanned, but does not give you biological research for it, only that it is a Xenotech creature & some other information on it.



The Dragon of Norfair looks more like a seahorse than a typical dragon. Seen in Metroid, Super Metroid, and Metroid: Zero Mission; it appears from a pond of lava and shoots fireballs. It can only be damaged by super missiles, fully charged shots, and screw attack.



Small, floating bugs which move horizontally back and forth and can only be killed with the Screw Attack. Rippers are commonly frozen and used as platforms to reach otherwise inaccessible areas. They are found on Zebes and come in many different forms.

Rocket Ripper


Red or purple-colored Rippers which travel much faster and have exhaust flames behind them.


Shriekbat concept art

Shriekbats are bat-like creatures which hang upside-down from ceilings. They have an extremely high body temperature and are very territorial - if anything wanders into their territory they fly towards the intruder and explode.



Sidehoppers are bugs found in Metroid: Zero Mission, Super Metroid, Metroid Fusion and Metroid Prime (although not as live enemies in Prime). They have two armored legs and jump side-to-side, hence their name. In Prime, the only Sidehopper is a Phazon-infused experiment locked behind an impenetrable door on the Orpheon. Later, its tank becomes infested with the vine-like Aqua Reapers.

Mysteriously, Brinstar (and many other areas in Zebes) are covered in green pipes which look similar to the pipes in Super Mario Bros., another Nintendo game. The Zeb flies out of these pipes at the enemy. However, it is very lightly armoured and does not do much damage. They continue to attack in infinite number, so standing in front of a pipe and repeatedly killing them for their health or missile powerups is an easy way to recharge in the absence of an energy station or missile station. There is a unique pipe enemy for each region of Zebes.


Samus blasting the first of five Zebetites.

Zebetites, sometimes called Zeebetites, are Mother Brain's life support units. A rapid barrage of missiles will cause them to shrink and eventually disappear, clearing the path for Samus Aran to advance. However, if the attack is stopped prematurely, they will grow back. Zebetites are extremely resilient and hard to destroy without Missiles, thus making their secondary purpose defense.

Theoretically, the energy provided by these Zebetites are required to keep Mother Brain alive. However, she does not seem to die spontaneously after the Zebetites are destroyed.

A Zebetite appears to be a tube filled with a red organic substance, connected to metalic pipes.

Zebetites have appeared in every Metroid game featuring the Mother Brain: Metroid, Super Metroid and Metroid: Zero Mission. The Metroid password contains a bit for each Zebetite, indicating whether it has been destroyed.


Zoomer concept art

Small semi-circular creatures with spikes along their backs. Their intelligence is limited to walking in set patterns along the terrain, meaning that Samus Aran must accidentally run or jump into them in order to be harmed.



A version of the Zoomer which is indestructable if shot by the Power Beam, but stops moving if fired upon and can be destroyed by other beams, such as ones composed of plasma or ice. In the side-scrolling games, Geemers are merely harder to kill.

Bio Barrier


The Bio Barrier is a living blockade. It will not attack you and cannot be defeated by any of Samus' weapons. The only way to destroy it is to use the small parasitic bugs that attach to Samus. When she approaches a Bio Barrier with bugs on her, they will leap off and quickly eat away at the barrier. It should be noted that unless Samus has the Varia suit, the bugs will damage her as well if there are at least four on her.



Arachnus is a creature originating from the planet SR-388. The creature is distinguished by its four toothed maw, segmented eyes, elongated neck, the hard shell on its back, and the large claws on its fore-arms. The creature is known to curl into an armored ball when threatened, and only periodically emerges from the ball in order to attack with either its claws, or by spitting fire from its mouth.

Arachnus made its first appearance in Metroid II: Return of Samus, in the depths of the planet SR-388, near the final area that housed the Queen Metroid. Here the creature disguised itself as one of the classic item balls held by the Chozo statues. Defeating it yields access to the Chozo statue that holds the Spring Ball.

Arachnus' 2nd appearance is as the first boss of Metroid Fusion. Its attack pattern includes curling up into a ball. Because of this, it carries the Morph Ball upgrade, which is absorbed by Samus when the core is destroyed. This version of Arachnus is only an X Parasite clone, not the original one from SR388. Its attacks include a flamethrower and sonic energy waves.



The Autoad is a jumping toadlike creature created by an ancient civilization. It is programmed to stop intruders.



An indestructible defense mechanism that flies horizontally. This creature activates a flamethrower when Samus comes near.



Autrack is a robotic creature from Metroid II: Return of Samus which travels along a track.

The Autrack can be found in numerous Chozo structures on the planet SR-388, where it acts as a point defense turret. The autrack is typically found hidden behind a wall or small structure, where it is protected when not firing. When it detects an intruder, its track arm extends, and the cannon fires, once it has fired, the arm retracts while the weapon reloads for another shot.

Blob Thrower


This plant creature is found on Planet SR388. It comes out of the ground and spits out little blobs that hover around, and then it retracts back into the ground. Killing the blobs is a good way to refill Samus' health and ammo.

Chute Leech


The Chute Leech is seen in Metroid II: Return of Samus, Super Metroid and as an X Parasite clone in Metroid Fusion, being found on both SR388 and Zebes. It has a flat body, and its attack is to jump up into the air, and then glide down with its parachute like body. The variant on Zebes has rows of teeth visible on its underside. They are more a nuissance than a serious threat. The X Parasite variant can release acid.



Gigantic bats that live in dark places. When Samus comes close, the Drivel dives toward her.



This crustaceous creature hides in the floor, only coming out to attack when Samus comes close. Appears in Metroid II: Return of Samus.



Gulluggs have long, needle-like noses and fly around in circles. They are found on Planet SR388. They frequently yield missiles when killed.



This mechanical defence mechanism attacks any intruder with 4 guns on its belly. It is impervious to Samus' weapons because of its hard plating.



Hornoads resemble frogs and hop around as such. Their name is a portmanteau of horn and toad. They frequently yield missiles when killed. They are only found in Metroid 2, and in Metroid Fusion in the form of X-Parasite copies. In Metroid Fusion, a Hornoad infects Samus with the X-Parasite.



Moheeks look like fish with tendrils coming out of their heads. They move slowly on the walls of the acid areas on Planet SR388. Although they are not aggressive, they do a relatively high amount of damage if Samus touches them.



The Proboscum is a harmless, invulnerable robotic drone found on SR388. There is much speculation over its original purpose, as it is typically found malfunctioning and clamped onto a vertical wall, where its swivelling arm can be used as a platform.



Septoggs are found on Planet SR388. They hover in one place and do no damage to Samus, so she can use them as platforms. However, their tiny wings can't support her weight, so standing on them causes them to descend quickly.



This immobile sentry is mounted on walls in the ruins of SR388, and becomes active only when an unrecognized lifeform enters range. The Wallfire is capable of projecting fireballs towards any threats, which can be frozen with the Ice Beam. They are also capable of regenerating damage if no threats are nearby.


A regular Beetle

Insects on the planet Tallon IV that attack in groups of two or more. These creatures burrow no less than ten feet below the surface of Tallon IV, if they feel movement aboveground they reapproach the surface and attack the intruder by ramming it.

Plated Beetle


Very much like its smaller cousin, the Beetle, it will attack an intuder by ramming it. Plated Beetles are stronger than normal Beetles, and are made more difficult to injure by a stronger exoskeleton that covers its front and side and is impossible to damage. Plated Beetles are vulnerable, however, in their back: a red tail-end is exposed and susceptible to damage. Plated Beetles are best defeated by sidehopping to avoid their ramming attacks, and using the opening that results to attack the weak spot.



Small scavenger insects which use frozen water to form an icy shell on their backs which deflects beam weapons and can only be destroyed by a missile. They build this shell by hanging upside-down during early development, forming a stalactite on themselves.



Flaahgra is a giant mutant plant poisoning the waters in the Chozo Ruins in Metroid Prime. It is located in the Sun Chamber and drops the Varia Suit when defeated. Flaahgra's energy comes from sunlight reflected from four dishes set around it. It has four tentacles that retract when no sunlight is pointing at Flaahgra, exposing its base to explosions from morph ball bombs.

It attacks by swiping at Samus with scythe-like arms and shooting a line of poison plants in your way. Flaahgra can also smack an already flipped dish back so it is directing sunlight back at it. Attacks from missiles and charge beam shots can momentarily stun Flaahgra giving Samus' a chance to flip a dish before Flaahgra starts reseting the dish positions.

In the game Samus's logbook counts Flaahgra's tentacles as a different creature. The tentacles are the roots of Flaahgra that are protruding from the base of his structure where its central nervous system is located.

Hive Mecha


A large, bulbuous security unit which houses the Ram War Wasps; a design flaw makes it weak around the points where it discharges the attacking wasps.

Incinerator Drone


The Incinerator Drone is a garbage disposal robot. It consists of a somewhat bulky vertical, heavily armored column that houses the majority of its parts, and rotating flamethrowers, placed opposite to each other. These flamethrowers are normally horizontal, but can tilt 45 degrees up or down. The incinerator drone's armor is impervious to weaponry, but in order to locate garbage and prey it must raise a red optical sensor which is vulnerable to concussive blasts such as missiles. When this is hit, a column of flame is projected vertically into a nest of barbed war wasps.



The Jelzap is a species of carnivorous underwater animal found in Metroid Prime. Jelzaps are vaguely triangular in shape, with two electrically bound skeletal sections, the top containing the brain, and the bottom containing the stomach and digestive tract. The Jelzap is at the top of the aquatic food chain on Tallon IV. To destroy one, wait until its middle core is revealed, then use the ice beam to freeze it and shatter it, or hit its core with a fully charged beam shot.


Magmoor concept art

Magmoors are lava serpents that dwell in the lava of the Magmoor Caverns beneath the crust of Tallon IV. These creatures are unable to see, however they do have a very accurate sonar. When prey is sensed they rear their heads from the lava and attack their prey with fire that they project from their mouth. When their skull has taken a large amount of damage, blood rushes to their head and it explodes.



These small animals are native to Tallon IV and are dangerous in packs, although harmless by themselves.

Parasite Queen


Found in the reactor core of the Orpheon; an extremely large Parasite that can be killed by shooting into its mouth. It was genetically modified by the Space Pirates to dramatically increase its size and give it the ability to shoot powerful energy blasts from its mouth. After defeating it, the Queen's body falls into the core, causing it to overload and eventually destroy the vessel.



The Plazmite is a small glowing insect that lights up and is attarcted to sources of heat. Although not too dangerous it can attack an enemy by ramming it.



Small, blue bugs which embed themselves in the wall when an enemy comes near and violently explode when touched or shot at.



A Sheegoth is a creature that appears in Metroid Prime. Sheegoths are found in the Phendrana Drifts area of Tallon IV. They are bipedal reptile-like creatures with a large mouth filled with razor-sharp teeth. Baby Sheegoth have a shell formed from ice which they use to protect their vulnerable back. Baby Sheegoth are fairly resilient, as they are generally only susceptible to damage on their aforementioned backside. Adult Sheegoths are much larger than baby sheegoths, and their invulnerable, spiked shells can absorb beam weapon energies, which the Sheegoth collects and fires at an enemy when built up. Sheegoths can also blow super-cooled air from their mouth, freezing prey solid, though in beta versions of the game, a Sheegoth was seen breathing fire. Sheegoths have poor endurance however, and hyperventilate after performing this attack, leaving their mouth vulnerable to weapons fire. Their soft underbellies are also vulnerable to concussive blasts.

In the sequel, Metroid Prime 2: Echoes, a creature called a Grenchler is similar to the Sheegoth.

Tallon Crab

Tallon Crab concept art

Small crabs which travel in very large numbers. They are harmless by themselves, but can be dangerous if encountered in packs. Tallon Crabs are seen throughout the wreckage of the Orpheon, on the Tallon Overworld.



A small creature which is impervious to damage, and is a hunter-gatherer with tripartite jaws. It is commonly used as a hazard in Morph Ball mazes, and will pick up the Morph Ball and bring it back to the start if touched.

War Wasp

War Wasp concept art

War Wasps are large wasps that are fiercely territorial. There are three types of war wasps in Metroid Prime:

  • War Wasps
  • Barbed War Wasps
  • Ram War Wasps

Additional types which were added in Metroid Prime: Hunters include:

  • Blue Barbed War Wasps
  • Red Barbed War Wasps

Barbed War Wasp


The most aggressive of the War Wasp family. This War Wasp has the ability to launch its stinger up to twenty meters and regrow its stinger in seconds. This War Wasp is found with the mini-boss, the Incinerator drone, in which the drone disturbs their hive, causing them to attack the player. In Hunters, the wasps were found on an inactive door, and came out of their hives when electricity passed over them. The hives wouldn't stop producing the wasps, and also had to be destroyed.

Red Barbed War Wasp

A species of Barbed War Wasp which shoots an extremely hot projectile.

Blue Barbed War Wasp

A mutated version of the Red Barbed War Wasp capable of surviving in a frozen environment and launching freezing stingers.

Ram War Wasp


The fastest and smartest of the War Wasp family. These War Wasps will surround an enemy and attack it by moving in circles around it, then attacking in unison. They are part of the boss fight against the Hive Mecha, which is a defense system that shelters Ram War Wasps and makes use of their coordinated attacks against intruders.



The Alimbics were a highly advanced civilization which were all but wiped out by Gorea after a meteor it was traveling on impacted one of their homeworlds. Alimbics' brains possessed large frontal lobes and they were quick decision makers, as well as proficient in psychic abilities such as telepathy and essence transference . Their heads hover in the air without use of a neck, like the Kriken. The Alimbics built two large space stations, called the Celestial Archives and the Vesper Defense Outpost. The Alimbics were the first to discover "essence transference", by using "essence transference" the Alimbics turn their bodies into concentrated psychic power. This was used to seal Gorea who was to great to be slain by conventional weaponry.



A piece of Alimbic defense technology shaped like a totem pole and with a rectangular "brain" on top. The many rotating turrets on its side can fire plasma or chemical laser beams; when they are blue they can be destroyed, but when they are red they are invulnerable. If all turrets are destroyed, the "brain" rises out of the top of the structure to fire energy bursts and can be shot to damage Cretaphid. The most advanced model of Cretaphid can move around the room, using its outer casing as a weapon.



Diamonts are an ancient silicon-based race whose bodies are composed of organic rock. Mondreus was their home planet. The Diamonts are now extinct, however, the reason is unknown. The entire race had simply vanished, leaving no clues behind. This was possibly due to genocide by an unknown evil foe.



Spire was the only remaining Diamont. Spire's life as a bounty hunter took him from one end of the galaxy to the other, while he continually searched for some information on the location, or fate, of the rest of his people. When he received a message from the Alimbic Cluster, he raced to the system with the hope that finding the Alimbics' source of ultimate power and solving the mystery of their lost race would help him solve the mystery of his own. His weapon was called the Magmaul and his alternate form is a large, spiked boulder which can scale walls. Spire can also walk (or roll) in lava without taking damage. Spire's Magmaul was copied by Gorea.

Weapon of Choice: Magmaul - A fiery grenade launcher weapon. When Spire charges it, it can set opponents on fire.
Alt. form: Dialanche - A rock-like sphere that can climb walls and spin rocks around it as an attack.



Enoema are a fictional race from the Metroid series. The only Enoema seen is Kanden, and it is unknown what an unaltered one looks like.



Kanden was an experiment to create a so-called supersoldier: a soldier that could hunt and kill anything, and was indestructible. However, Kanden's mind and psychology were still no more than a mere mortal's, thus meaning that his brain could not withstand the awesome and complicated neural combat encoding sequences. This completely transformed his mind, leaving him as a ferocious, unbelievably powerful and dangerously unpredictable superhuman. Kanden escaped the research lab, killing the scientists that made the enhancements and surgical modifications. Kanden then took great advantage of his strength, near-invincibility, and near-immortality by trying his hand at becoming a bounty hunter. It would be impossible to trick him into not doing something violent; anything he sees, he kills at his own unpredictable will, and his conscience is rendered useless by the neurological enhancements. Built with programming to hunt, combat, and destroy, he could be the ultimate super-soldier. When Kanden received word of a powerful super-weapon in the Alimbic System, Kanden sees a great advantage that he can grasp in his superhuman hands. Kanden's Volt Driver was copied by Gorea.

Weapon Of Choice: Volt Driver (A power shot that, when charged by Kanden, homes in to the opponent disrupts the opponent's visor. A charged shot can hit more than one hunter.)
Alt Form: StingLarva (When attacking, a piece is broken off from the tail and homes in on a target ready to explode. Can only break off one bomb at a time )



Gorea is the name given by the Alimbics to the creature that arrived on a meteor in gaseous form. It proceeded to copy their cellular structure and destroy their civilization in a swift rampage of terror. Gorea's head is very similar to the Alimbics in appearance - it floats above its body and has a similar "crest." Gorea has three legs and is impervious to conventional weaponry except when it is the same color as the weapon being used against it, and both of its shoulders are destroyed. Gorea is slightly bigger than Samus, and the Seal Sphere is located in the middle of its body, from which it draws power. Once its two shoulders are destroyed, it turns upside-down and brings the seal sphere above it, using the Sphere to attack, but the Sphere is also vulnerable to fire from weapons. The Omega Cannon must be used to destroy its second form. The Alimbics were able to contain Gorea by using the Seal Sphere and trapping it within the Oubliette prison. The Oubliette was then sealed in another dimension called the Infinity Void, which could only be opened by firing the Alimbic Cannon on Alinos, which tore a rift between dimensions and opened the Infinity Void, granting access to the Oubliette. The keys to activate the Alimbic Cannon, the Octoliths, were scattered throughout the Alimbic Cluster, each guarded by three other keys and a variant of Cretaphid or Slench, and each contained separate coordinates and frequencies which the Alimbic Cannon needed to open the Infinity Void. Gorea appears in Metroid Prime: Hunters as the final boss. Gorea drains the powers of the six hunters before fighting Samus.



Intelligent sentry robots built by the Alimbics to guard their facilities. Guardians can shoot a variety of projectiles, including ice, plasma, electricity and magma. They have black diamond-shaped bodies with two legs and a large yellow dot where their "heads" are, which functions as a turret. Guardians are more skilled at fighting than their less advanced robotic counterparts, and will bunny-hop to avoid fire, fight in packs, and use cover.



Continuing the tradition of biped lizard-like creatures started in Metroid Prime, the Ithrak are found in Metroid Prime: Hunters. It is something of a mix between a Skree and a Sheegoth, in the sense that it waits for the player on the ceiling, and when the player arrives, drop down (like a Skree) and attack in a way similar to that of the Sheegoth. There are two varieties of Ithrak: the Lesser Ithrak, which can be shot on any part of its body, and the Greater Ithrak, which, although it can only be harmed by shooting the backside, can be destroyed with only one missile blast. The Greater Ithrak only appears twice, defending an Alimbic Artifact in the Celestial Archives and another on Arcterra, in Sanctorus. All Ithrak are more vulnerable if shot while hanging from the ceiling.


File:Trace small.jpg

The Kriken Empire is one of the most hated and feared races in the galaxy. They move like a swarm from planet to planet, conquering it and adding it to the Kriken empire. The Kriken are giant red insectoid creatures with skinny appendages. Their heads only have one red eye and no other features. Another noticeable aspect of the Kriken is that they have no neck; their heads hover in the air above their shoulders with no connection to their body, much like the Alimbics. A glowing orb is located at the center of their bodies. Trace also has a hand scythe,which is similar to the energy scythes used by the Space Pirates.



The Kriken youth Trace was undergoing a rite of passage, searching for worlds that the greedy and evil Kriken race can invade. Using sophisticated Kriken technology, Trace could morph into a three-legged mechanism called the Triskelion that could lunge at its enemies with vicious needlepoint claws and become almost completely invisible when stationary. Trace was seeking the Alimbic treasure to enhance his power. Trace's Imperialist was copied by Gorea.

Weapon of Choice: Imperialist (A sniper beam that can zoom onto opponents. While the beam is equipped, Trace can become partially invisible if he remains still)
Alternate Form: Triskelion, uses a lunging attack that can inflict very heavy damage if a direct hit. As with using the Imperialist, Trace may become invisible in this form while not moving.

Psycho Bit


Small flying robots which shoot a variety of projectile types. They come in 4 versions - the higher versions tend to be more resilient. Regular Psycho Bits shoot plasma, and the green incarnations are more powerful and powered by a nanoscale nuclear reactor. The later versions shoot magma, electricity and ice.



The Quadtroid is a genetically engineered species created from leech and lizard DNA. The creature is built similarly to a Metroid in that it has a large green membrane and nuclei inside of it. It also latches onto creatures and saps energy similarly to a Metroid, and, like a Metroid, can only be removed with a Morph Ball bomb. However, instead of floating like a Metroid, the creature crawls on the ground with it's claws and possesses a tail. It is not known if the creature was created by the Chozo or someone else, but it seems that since it has so many similarities to the Metroid, one could guess that it was also created by the Chozo.



A giant, biomechanical eyeball developed by the Alimbics to safeguard the Octoliths. There are four Slench variants, each progressively harder to destroy. Slench is invulnerable while connected to the wall, and uses three synapses to channel energy to energy turrets. If all synapses are damaged, Slench separates from the wall and fires at the player, but it is vulnerable if shot in the center of the eye. Later Slench models have the ability to charge at the player, roll around the room and shoot different projectiles, and have synapses shielded against all except one type of weapon.





Sylux is a character in Metroid Prime: Hunters. Little is known about Sylux other than that the bounty hunter had an intense hatred for the Galactic Federation and Samus Aran. Sylux's alternate form was a small hovercraft called the Lockjaw, which layed tripwire mines. Two must be laid to create a tripwire, which can be left as a trap. If Sylux lays a third mine, all three explode onto anyone in the center of them causing massive damage. His weapon of choice is the Shock Coil, a beam that fires bursts of high-density neutrinos, and when used by Sylux allows him to absorb the victim's energy. Also, in low gravity areas, Sylux's lockjaw form can fly by rapidly laying mines. Sylux's Shock Coil was copied by Gorea.

The game's log entries state that Sylux's suit, gunship known as the Delano 7, and Lockjaw technology are all stolen Galactic Federation Prototypes, and Sylux's Shock Coil is made out of banned nanotechnology and according to it's scan is also a Galactic Federation Prototype.

Sylux's species is unknown, although the game's starting video reveals that he comes from Cylosis, and he is referred to as a male by the game's developers. The intro video shows the extent of his hatred for the Galactic Federation, showing Sylux dive-bombing an unsuspecting GF trooper, crushing him, then screaming defiantly at two other troopers that accompanied the one he killed. It does not, however, explain the reason that Sylux hates the Federation.



The Vhozon are an alien race with a fanatical view of morality that exceeds virtually any other race in the galaxy. To enforce their sense of justice, they have sent Noxus to the Alimbic Cluster in Metroid Prime Hunters to make sure the "Ultimate Power" that the Alimbics left behind does not fall into the wrong hands.

The Vhozons' home planet is Vho, a planet that has an extremely cold climate and is covered in ice. Because of this, Vhozon can fold into a rapidly spinning top to keep warm. Noxus uses this as his alternate form in Metroid Prime Hunters, and can use his appendages to lash out at enemies while spinning.



A spiritual being who walked a harsh, righteous path, Noxus has became a bounty hunter to administer justice to the galaxy's criminals and evildoers. Although not all of the other characters could be classified as "evil," Noxus probably fought them because he trusted no one except himself with the "Ultimate Power."

Noxus's weapon of choice is known as the Judicator. It fires supercooled plasma nearing temperatures of absolute zero that ricochet off walls, and fires three bursts when charged. When Noxus uses it, the charge will freeze opponents solid on contact. His alternate form, the Vhoscythe, is a contracted spinning form with a blade that can extend and viciously slash enemies on contact.

NOTE: It should be noted that the in-game explanation for the Judicator is scientifically impossible, as plasma cannot be supercooled without losing the properties that make it plasma.



Small, drum-shaped robots which are equipped with two turrets capable of firing a range of projectile types. Voldrums roll around on the floor and are much easier to kill than Guardians.

Space Pirate




See the Space Pirate main article to learn about Weavel.


Amorbis firing a beam attack

Amorbis is a giant, wormlike boss guarding the Dark Agon Temple in Dark Aether, with three separate bodies. The main power source of Amorbis is a giant black sphere surging with dark energy.

Amorbis will break off from its sphere and will leap out of the sand at random spots trying to ram Samus. Once its outer shell is destroyed it will attach to its sphere. Amorbis will then gain armor and a hornlike head. It will use dark energy to destroy the light crystals. It can also charge up to launch a hyper destructive beam attack. Once Samus destroys its head armor, she must transform into the Morph Ball allowing Amorbis to suck the Morph Ball in its mouth, which is vulnerable to Morph Ball Bombs. After Samus repeats the process it will latch two heads on, doubling its attack power. Once she destroys those it will attach three heads to its sphere. Once all heads are destroyed, Amorbis dies and Samus receives the Dark Suit.



A funnel-shaped, black aquatic predator whose only vulnerability is its mouth. They ram their prey, then use their three mandibles to eat it.

Alpha Blogg


The alpha male of the Bloggs, this gigantic Blogg is a mini-boss which, when defeated, grants Samus the Gravity Boost.


Chykka in its Dark Adult form

The Chykka is the insectoid boss guarding the Dark Torvus Temple. When Samus enters the temple, the Chykka is still in its cocoon; a larva emerges from the cocoon when Samus shoots at it. It swims around in the water, occasionally splashing dark water at Samus, and sometimes surfacing and trying to drag Samus in its mouth.

Once the larva is destroyed, the adult form of the Chykka emerges. This is by far the most dangerous form, because it frequently spits dark water at Samus. To defeat this form, weak spots on the back of the wings must be destroyed.

The Chykka's final form, the Dark Adult, spews forth dozens of small Chyklings from its eggsac. This is by far the easiest form to defeat, because it can be destroyed with conventional means, and the comparatively weak swarm of Chyklings provide plenty of extra health and ammunition.

The Chykka switches forms from Adult to Dark Adult each time Samus hits its weak spot often enough. After the Chykka is destroyed, Samus is rewarded with the Dark Visor.



Grenchlers are a fictional water based reptilian predator found on planet Aether in Metroid Prime 2: Echoes. They are well armored and deadly at any range, however their back shell is vulnerable to concussive blasts. At close range, they will often attack their prey by attacking viciously with their powerful jaws, although if unable to they have the ability to charge and fire a burst of electrical energy at their foes. They have two thick, muscular legs,a weak orange shell on the back of their body, and they are similar to a raptor or t-rex. The also posses powerful jaws and often travel in pairs. They can also apparently breathe in the water and may even live in it, only emerging for prey.

This species is often considered to be somewhat related to the Sheegoths, a species found in Tallon IV. This hypothesis is based on the fact of the rough design similarities and behavior of Grenchlers with the young form of the Sheegoths. However, the similarity in design may also be attributed to the developers of the game wanting a similar enemy in Metroid Prime 2, however in a different environment in which the Sheegoth would not survive.

The Ing are a fictional evil race that is the major foe of Samus Aran in the video game Metroid Prime 2: Echoes. Their name is the Luminoth word for 'terror'. Ing generally take on a dark, hideous, alien look, unless they have possessed other life forms, in which the host remains mostly the same, except that it takes on a blacker hue, spines, and an Ing-like eye structures.



These huge robots were created by the Luminoth to guard Sanctuary Fortress. Ingsmashers are large humanoid-shaped robots, with two spheres on the ends of their arms rather than hands. They are armed with rocket launchers, a barrier generator, and the ability to generate shockwaves. These armaments ensured that Ingsmashers lived up to their name. The Ing eventually possessed a few, but the majority simply went rogue. Other than its darker armor, the Ing-infected versions of the robot are virtually the same as their Light Aether counterparts.



A race of intelligent, moth-like creatures, whose name is a portmanteau of "luminous" and "moth." They are the original inhabitants of Aether and almost lost the war with the Ing - they put all the remaining members of their race in stasis except one, U-Mos, who helps Samus and later gives her the Light Suit.



4-legged robots designed by the Luminoth. They are equipped with turrets and can roll up and spin rapidly to damage the enemy.



Quadraxis is the boss guarding the Dark Sanctuary Temple.

Quadraxis is a high security drone created by the Luminoth, but was taken by the Ing to serve them. Once the energy of the Sanctuary Fortress was taken, the Ing needed to guard their own, so they took this giant destroyer with them to guard the Ing hive's planetary energy. Quadraxis guards the final energy storage module of Dark Aether, which if taken away will lead to the ultimate destruction of Dark Aether.

Quadraxis' attacks include Annihilator beams, dodged by a simple boost in Morph Ball form, missile, and a tornado-like spin attack similar to the one used by the smaller quad robots, except this one draws you in like a magnet, only avoidable by hopefully using the Boost Ball. It can be damaged by attacking its leg joints with light beam charge, and foot weaponry with Boost Ball, or Morph Ball Bombs. Once its main body is crippled, the head will lift off and attack on its own. The head will receive shielding from sonic frequencies coming from the transmitter in the main body, and cannot be damaged. The link must be severed by using the Echo Visor to first damage the transmitter in the main body and then attack the receiving antennae in the head, destroying them. While the link is being re-established, the head will summon Dark Quad MB and CM robots. Once all of the receiver antennas in the head are destroyed, the head can be stunned with shots, then, using the main body's legs as ramps, Samus must boost-ball-jump and attach to the head using the Spider Ball, and bomb its two morph ball slots, one at a time.

After defeating Quadraxis, Samus will acquire the Annihilator Beam.

It must also be noted that in the light version of the temple entrance you can see various parts of the disassembled Quadraxis robot scattered throughout the room.



Botwoon is an orange snake-like mini-boss in the Maridia area of Super Metroid.

The botwoon is a burrowing creature, and is encountered snaking between various holes in the wall. When threatened, it will stick its head out of a hole, much like an eel, and then spit a form of corrosive on its attacker.



The Cacatac is a plant lifeform on planet Zebes, that closely resembles a barrel cactus. It is mobile, which is unusual for a plant, and can shoot spikes. It has appeared in Super Metroid, and bears a resemblance to Seedlings in Metroid Prime

The cacatac is a plant standing roughly 1.3 meters in height, standing on a number of short spiney legs. The cacatac's body is covered by rows of spikes, which it is able to launch as projectiles. Though normally green, cacatacs cand be found in a variety of colors, including red and blue.



Covern are ghosts that haunt the Wrecked Ship in Super Metroid. After the defeat of Phantoon, they will cease to haunt the ruins. They try to materialize wherever Samus Aran is standing, simply move and then shoot them to kill them.



Crocomire is a multi-eyed lizard-like creature that guards part of Norfair in Super Metroid. It was originally going to be in Metroid: Zero Mission, but it was removed for unknown reasons.

Crocomire is a large, 8-eyed, reptillian creature, standing at about twice Samus Aran's height. Its red flesh, though nearly indestructable, appears to be in a perpetual state of melting. The creature's long bony arms are connected close to its back, but are long enough to reach well round its immense girth. Despite its short legs and portly build, crocomire's movements are surprisingly quick, and it is easily capable of charging its prey.

He is defeated by shooting missiles, super missiles or regular shots into his mouth which cause him to stagger back. He is defeated when he is pushed back onto the weak spot on the floor, causing him to fall into the acid and die. Then his skeleton will try to attack but collapse instead. If left alone long enough, he will push Samus back into a wall of spikes.


File:Etecoons and Dachora.gif
Etecoons sleeping next to dachoras from Metroid Fusion

The Dachora is a fictional alien species resembling a green ostrich or emu. It first appeared in Super Metroid, then in its sequel Metroid Fusion. In Super Metroid Samus Aran encouters the dachora after getting the Speed Booster; the dachora teaches her how to use the "Shinespark" technique. Rescuing it at the end of the game results in a slightly different ending. In Metroid Fusion the encounter is a required part of the plot; Samus must rescue them for the story to proceed.


Draygon can be easily defeated by electrocuting it with the Grapple Beam

Draygon is a boss that inhabits the far east end of Maridia in Super Metroid. Samus Aran must defeat it in order to obtain the Space Jump and to unlock the path to Tourian.

Draygon is a large, green crustacean-like creature with markings that resemble human skulls. Draygon is often referred to by fans as a female because of the several harmless Evirs (which resemble Draygon) that surround the area before the fight and drag Draygon's body away when defeated; however, there is no conclusive evidence of gender. Its attacks include quickly zooming on and off screen, spitting out viscous saliva, and lifting Samus off the ground and lashing her with its tail. Draygon's shell is extremely tough, with its yellow underbelly being its only weak point.

Draygon can be defeated in two ways: shooting charged shots or missiles at its underbelly or (once grabbed) using the Grapple Beam to electrocute Draygon by hooking it onto damaged electrical turrets on the wall. Utilizing the second method causes negligible damage to the player, making it easy to defeat Draygon, however, it is not immediately apparent.



The Etecoon is a fictional alien species that somewhat resembles a koala. It has appeared in the videogames Super Metroid and Metroid Fusion.

In Super Metroid, Samus Aran finds a group of three Etecoons deep in the caverns of Brinstar. They show her how to execute the Wall Jump technique. If Samus rescues the Etecoons and Dachora at the end of the game, the ending becomes slightly different.

In Metroid Fusion, Samus' computerized CO, Adam, detects signs of life in the Biologic Space Labs Habitation Deck. When she goes to investigate, she finds not human survivors, but a trio of Etecoons, and an adult and baby Dachora.



The Evir is a crustacean-like creature that stars in Super Metroid. It resembles a small version of Draygon but orange. There are also green Evirs that circle Draygon. They are also in Metroid Fusion's AQA (Sector 4).


Keyhunter drawing from the Super Metroid Instruction Manual.

The KiHunters, also called the Keyhunters have allied themselves with the chief villians of the galaxy, the Space Pirates.

The KiHunters are insectile creatures closely resembling wasps. They have four limbs and a set of wings. The creatures are most common in their flying form, where they attack with their claws by swooping down upon their victim from above. All members of the species will lose their wings when damaged. They then revert to a ground-based mode of travel that involves hopping, and at this point they will spit highly corrosive acid at anything that threatens them. The KiHunters are apparently, like the Space Pirates of Zebes, a sentient species, as the Super Metroid instruction manual refers to them as pirates from another galactic system who helped rebuild the fortress on Zebes after Samus Aran destroyed it on her first mission there.

KiHunters are found in both Super Metroid and Metroid Fusion, although in the latter game, they are only X Parasites mimicking the true species. The cocoons which the Zero creatures in the TRO sector form after you defeat the Giant Choot boss later hatch into Kihunters after the station-wide power outage occurs. This apparent metamorphosis of one species into another is a result of the ability of the X Parasites to recombine DNA from multiple hosts.

KiHunters can be found in virtually all environments on Zebes, ranging from the damp caverns of Crateria to the hottest pits of Lower Norfair. KiHunters come in several different colors, generally indicative of their strength. The fact that their color scheme is always very close to that of their environment, even in artificially constructed areas, suggests that they may employ some degree of camouflage.



Mochtroids are the unfortunate result of the Space Pirate's failed attempt to clone Metroids. They are distinctly different from their progenitors in that they only possess a single neural brain node, instead of three the (original) Metroids naturally possess. As well, they are no larger then half the size of a Metroid, and most Mochtroids possess only 1/10 the strength of a natural Metroid.



A large, dark green floating creature, resembling a cross between a jellyfish and the disembodied head of a cyclops. Phantoon is the guardian of the Wrecked Ship in Super Metroid. Its attacks consist of blue flame which it can summon in various patterns. Phantoon can only be damaged when it is visible, after an attack - most of the time it is transparent or invisible to Samus. If hit by a Super Missile, which does double damage to Phantoon, it will move to the center of the room and attack with many waves of blue flame, blocking the entire room but which can be easily dodged using Morph Ball mode. When Phantoon is destroyed, power is restored to the Wrecked Ship and Covern stop appearing.

Spore Spawn


The plantlike boss of Brinstar, combining falling spores (hence the name) and a waving motion of its elongated plant-like neck to attack. The falling spores can be shot for energy and missile powerups, and Spore Spawn's direct attacks can be avoided by using Samus' morph ball mode. This boss is defeated by shooting into its vulnerable inner core when it opens.


A Torizo from Super Metroid

The Torizo was introduced in Super Metroid. It is commonly perceived as an evil Chozo statue. Chozo statues are usually beneficial to the player, giving new equipment and items. A Torizo statue, however, comes to life and attacks the player.

Two Torizo statues appear as mini-bosses in Super Metroid. The first, which is encountered very early in the game in Crateria, poses as an ordinary Chozo statue holding the Morph Ball Bombs, and comes to life to attack when the bombs are taken. The second Torizo statue, which is gold and considerably more powerful than the first, is found late in the game, in the depths of Norfair. It holds no item, but defeating it earns the player the Screw Attack.

A third Torizo statue is encountered just before the end of the game in Tourian. This one, however, is only a dried-up husk that crumbles when touched. It is soon revealed that the creature was sucked dry by a giant Metroid, giving the impression that the player was saved the trouble of battling this final, presumably most powerful, Torizo.

The Metroid Galaxy Guide website claims that the Torizo statues were simply a biomechanical security system developed by the Chozo to protect some of their most important artifacts from intruders, with the statue activating upon removal of the item, and attacking the intruder.

One of the early bosses in Metroid Fusion is an X Parasite mimicking a Torizo, representing the most recent representation of this enemy.

The word "torizo" is Japanese for bird statue. As such, it is really just synonymous with Chozo to describe the statues that give the power ups. However, since only the referenced statues attack Samus, it produced the misconception that the Torizo is a new, evil race of Chozo.



A giant tortoise as large as Samus which lives in Maridia. If disturbed, it retracts into its shell and spins back and forth. If Samus jumps on top of it, it will fly up to near the top of the room, allowing her to obtain powerups. It will damage Samus if she is hit by the shell while it is moving side-to-side. There are also some harmless baby turtles crawling around it.



A Zebesian is a weak Space Pirate that guard the Craterian region in Super Metroid. They have a weak plasma attack and can hang from walls. They are the weakest of the Zebesian Space Pirates. Zebesians are also found in the B.S.L in Metroid Fusion and they are also able to cling to walls. They are very common in sector 1 (SRX).

Zebesians are crab-like humanoids with large claws instead of hands. They appear to have glowing compound eyes, and segmented joints. Zebesians are typically seen with green and pink armor, but also appear in shades of grey, gold, red, and blue, but the X imitations are purple or gold.

Zebesian Commander


Zebesian commanders are tough Space Pirates that wander the depths of Maridia in Super Metroid. They have the ability to hang from walls and can only be destroyed by the Plasma Beam.

Zebesian Elite


The second most powerful Space Pirate in Super Metroid, they are only encountered during your escape from Tourian. They are seen on foot and hanging on walls. They can only be destroyed by screw attack or Hyper Beam.

Zebesian General


These are the most powerful Space Pirate in Super Metroid that you can encounter. They are found on foot and on walls in Ridley's ruins. They have such powerful armour, they can only be destroyed by screw attack, charged plasma beam and super missiles. They are the generals of the Space Pirates on Zebes.



Yellow creatures very similar to crabs. They behave exactly like Geemers.

Fake Energy Tank and Missile Expansion


These creatures look like Energy Tanks or expansions until Samus gets close to them; then, they spread bat-like wings, reveal a set of eyes and fly off, hurting Samus. The result of an X-Parasite possessing an Energy Tank or Missile Expansion.



Nightmare is a biomechanical organism engineered in the Biologic Space Laboratories to be an unstoppable weapon. It appears as a X-clone boss in Metroid Fusion, in the ARC sector. Nightmare has an integrated magnetic field generator, which causes missiles to fall to the ground before reaching their target, and machine guns, as well as heavy shielding. If Nightmare is damaged enough, its field generator is destroyed, and its mask falls off to reveal its face, which is covered in green slime.



An aquatic serpent-/dragon-like creature, also known as Ishtar in the videogame Metroid Fusion. It has the ability to swim at incredible speed. It is kept in the AQA sector of the Biologic Space Labs. After the X-Parisites infested the BSL, Serris was killed and copied by a Core-X. Upon its defeat, Samus Aran receives the Speed Boost.

X Parasite


Main article: X Parasite

X Parasites, often referred to as simply X, are parasites who copy their prey. X Parasites infect a host body and eventually kill it. They would seem to take the host's DNA and use it in order to copy its form.

X Parasites are natives of planet SR388, and were seen as a significant enough danger by the Chozo that they created the Metroids in order to control their numbers. Metroids are the only creatures they cannot infect, being absorbed by them instead. After Samus was infected by an X-Parasite and cured via a Metroid cell infusion, she was able to absorb them as well.

They are the main antagonist in Metroid Fusion, most notably in the form of SA-X, an X Parasite that took Samus' form. Outside of its host body, an X Parasite may take several forms, all conferring a benefit to Samus if she absorbs them, except for the larger blue X Parasites, which harm Samus until she gains the Varia Suit.
