Senior Centipede (ムカデ先輩, Mukade Senpai; Viz: Centisenpai) was a Mysterious Being that appears after Metal Bat defeats Junior Centipede and Venus Mantrap.


Senior Centipede Full Body

Senior Centipede full appearance

Senior Centipede is as his name implies, an extremely large centipede. His width is 3 to 5 meters wide.[1] Unlike Junior Centipede, he is completely armored and is also completely black. He has several armor layers covering his face and has two sets of eyes as well as two noses.


He is rather confident in his abilities. He has a rather sadistic nature when he believes he has the advantage against an opponent.


Sometime in the past, he met Junior Centipede and ever since then has grown to have a close bond with the other centipede monster.

Senior Centipede Emerge

Senior Centipede emerges

Before Metal Bat could finish Junior Centipede off, Senior Centipede erupted from the ground. Senior Centipede forced Metal Bat, the Hero Association's sponsor, and the sponsor's child out of the restaurant. Outside, Rafflesidon emerged from the ground and started releasing sleeping gas. The sponsor and the sponsor's child immediately fall unconscious. Metal Bat is left to fight two Demon level monsters.[2]

While Senior Centipede and Rafflesidon fight Metal Bat, Metal Bat comes under hypnosis when Rafflesidon releases some gases. Senior Centipede then proceeds to continuously attack Metal Bat, but Metal Bat eventually comes out the hypnotic state. Senior Centipede is then defeated by Metal Bat with one strike.[3]

Abilities and PowersEdit

Given his status as demon level threat and the fact that he was able to give S-Class hero Metal Bat some difficulty, Senior Centipede was a very powerful monster.
