Black Hole
Black Hole was one of the Seven Akuma Choujin (悪魔超人, Devil Supermen). He had an all black body and a giant hole in his head in place of a face. He possessed the ability to travel through shadows and the hole in his head lead to another dimension, which he could suck his opponents into like a black hole. However, Black Hole’s body is linked to the dimension, and any wound he receives creates a small crack in the dimension, giving his opponent a way to escape.
Black Hole has a very gentlemanly demeanor, and will often converse with his opponent (usually in an attempt to trick them).
In the movie Counterattack! The Underground Space Choujins he is revived by Hydra King as the more powerful New Black Hole (ニューブラックホール), but he is eventually defeated by Ramenman.
