Abilities & Powers
Hundred-Eyes Octopus was classified as a Demon-level threat, implying that it was a fairly powerful creature. It was able to fend off and overpower several A-Class and B-Class heroes until a pair of S-Class heroes defeated it.

Physical Empowerment: By devouring concrete, Hundred-Eyes Octopus got bigger and stronger.

Omnidirectional Vision: Given its many eyes, Hundred-Eyes Octopus had a 360° field of vision.
