[edit] Super Metroid

Powamps are passive creatures that dwell in the depths of Maridia on Zebes. They generally just float around in the water immobile and inflate whenever other creatures come near. They aren't aggressive, and can be latched onto with the Grapple Beam for use as a makeshift Grapple Point. But despite their docile nature, Powamps will cause damage if touched, as well as explode if Samus shoots one; the explosion will launch several spiked projectiles in all directions. Worthy of noting is the Powamp's physical resemblance to Phantoon, though no connection is known to exist between the two.

[edit] Metroid Fusion

In Metroid Fusion, several X Parasites have been able to infest/mimick the Powamps that were living in the BSL station. The X have modified the creatures' genetic structure, giving them new traits, such as darker coloring and a spiky exterior. They are encountered only in the watery environments of Sector 4, AQA. They are most notable for their frustrating nature, in which they inconveniently block the paths to small access routes throughout the sector by inflating when Samus approaches. To approach these without causing them to enlarge, they need to be frozen from afar by a Diffusion Missile, the only weapon capable of incapacitating them from an indirect angle. When frozen in an inflated state, they can be used as platforms to reach high areas as they don't cause damage when they are frozen. They can be killed with the Screw attack.
