Super Metroid/Enemies

For bosses please see Super Metroid/Bosses.

Bombu
Electrical beings resembling the nucleus of an atom. They sometimes emerge from glass-encased storage tubes attached to the floor of the Wrecked Ship.

Bull
A round, floating creature, which emits puffs of gas from many exhaust pipes on its surface. It is attracted to Samus and moves toward her, but can only be destroyed with a Super Missile or the Grappling Beam. They can be found in the Wrecked Ship and the sand pits of Maridia.

Cacatac
The cacatac is a plant standing roughly 1.3 meters in height, and is found in Brinstar and Norfair. It stands 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 can be and are found in a variety of colors, including red and blue.

Covern
Covern (sometimes called Koben) are ghosts that haunt the Wrecked Ship in Super Metroid. They are dark brown and have multiple skull-like heads. After the defeat of Phantoon, they will cease to haunt the ruins, suggesting that they were in fact caused by Phantoon. They try to materialize wherever Samus Aran is standing, but the player can simply move and then shoot them to kill them.

KiHunter
The KiHunters are insectoids closely resembling wasps or praying mantises. They have four limbs and a set of wings. They 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.

Oum
A green mollusk which can curl up into a ball much like Arachnus to block passages. They are only found in a single area in Maridia.

Shriek Bats/Skrees
Shriekbats are bat-like aerial creatures who 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. They have two large claws, and when they slam into the ground they shatter into flying shrapnel (traveling only a few spaces from where it explodes).

Space Pirates
Space pirates are the first units you encounter within Super Metroid. They look like mechanical praying mantes with serrated arms. They have the ability to shoot lasers and leap from wall to wall in small areas.

Tan-Gray Pirates
Commonly dubbed 'ninja pirates,' they are the most powerful Space Pirate in Super Metroid and are found only in a room near Ridley's where they function as a miniboss of sorts. They have such powerful armor, they can only be destroyed by charged shots and super missiles, and only once they turn gold (which occurs after they do a spin-jump). Rather than firing lasers like other space pirates, they rely on spinning jumps, a few karate moves, and flying kicks. They also occasionally throw their claws (resembling boomerangs when airborne), which somehow respawn a short time later.

Zoomers
Zoomers are the basic enemy of the Metroid series (seen throughout all games). In Super Metroid, Zoomers are extremely easy to kill, slow, and a minor annoyance throughout the game.

Red Zoomer
Alternatively, a red version exists; labled an easter egg for it's strange behavior and how it does not affect gameplay at all.

Geemers
There is a common mixup between Zoomers and Geemers, in that Geemers are the upgaded version of Zoomers (in Metroid Prime Geemers have retractable spines) with a higher tolerance to firepower.

Zeela
Yellow organisms very similar to crabs. They behave exactly like Geemers.
