A Geega is a flying creature from the Brinstar region on Zebes that mostly spawn from Air Holes. Their in-game sprites suggest they have a disproportionate body, as they have a relatively large head on a small body. They attack Samus by flying towards her with their large mouths open to harm her with their fangs. They are resistant to Acid, as they can be seen rising out of pools filled with the substance in Metroid and its remake, Zero Mission.
Like all other bioforms which emerge from Air Holes, it is assumed that Geegas have colonies built within the structures where they infinitely spawn from.
It bears a similar name to the Dessgeega species, but has no known relation.
Official data
Metroid manual
"They come out through air holes and fly sideways. There are two types and the brown ones have twice the strength."
1986 manga
"Flies out of the vents. As they are weak, it is easy to collect energy from them."
Official Nintendo Player's Guide
"It has horns with deadly poison, and charges at you with them. It often appears from vents."
Super Metroid Nintendo Player's Guide
"Geegas appear from their pipes at all the wrong times. They're quick."
Cancelled Metroid Fusion appearance
By hacking into Metroid Fusion 's game data, it is revealed that the Geega species were originally intended to be encountered by Samus. The sprites (presented below) show Geegas with an unusual coloring scheme, as well as bat-like wings, spikes on their backs and enlarged claws. These different traits were undoutedly caused by the X Parasites' DNA manipulation in their attempt to make the Geegas more fearsome and possibly stronger (as is the case with most of the X's mimicries and victims).
