Phantoon

Phantoon is a spectral entity fat balloon monster that is mostly intangible and thus invulnerable to any form of attack, except for its single eye. It is this eye that, when open, serves as his connection to the corporeal world and can be damaged.

Phantoon feeds off raw energy without directly interfacing with wires or equipment and has only been seen drawn to sources of energy from abandoned ships, such as the Wrecked Ship and BOTTLED SHIT, where he currently resides. The specter also taps into Mother Brain's "vicious brainwaves," meaning that Mother Brain may have some control over him, or that Phantoon simply feeds off of her energy. Nevertheless, based on his portrayal among the bosses in the Golden Statues, Phantoon appears to be allied with the Space Pirates in some capacity.

Battle
Phantoon is a slippery little shit, and floats around the room shitting flaming eyeballs. Phantoon is so afraid of Samus running at him and blasting him with missiles he freezes in place like a deer in headlights allowing you to blast him in his ugly face with more missiles than would be possible normally. This is known as Scaring Phantoon Shitless.
