16) Octagon (Kirby)


Octagon initially appears as a tiny pink octopus drifting around in Dedede’s royal fish tank with black eyes and no apparent purpose. Unless he looks into a possible victim’s eyes, in which case he is utilizing hypnosis and his eyes are glowing green, those eyes are black dots in his smaller form.

When Octagon assumes his real form, he enlarges and takes on the appearance of a more terrifying Flotzo. Octagon dwarfs Dedede’s palace almost completely with his size. He has emerald eyes that are sunken in and dark red skin.

17) Ophis (High School DxD)


Ophis is a pretty young girl with long black hair that reaches her hips and black eyes (gray in the anime). Her ears are different from those of a typical human being in that they have pointed tips, yet her long, black hair conceals this characteristic.
