One-Punch Man Wiki

Junior Centipede (ムカデ後輩, Mukade Kōhai; Viz: Centikohai) was a Mysterious Being and a member of the Monster Association. He was killed by Metal Bat.


Junior Centipede is a large centipede monster with a humanoid face. The monster is colored red in the anime.


His personality is left rather ambiguous but he does show respect towards Senior Centipede and those who defeat him in battle such as Metal Bat. He also seems to be a little arrogant as he believed he is the largest centipede when he used to live in a cave and developed into an unusual size.


Junior Centipede was a centipede that grew to an abnormal size in a cave and developed a strong self-esteem. He believed that he was at the top of the pyramid until he met Senior Centipede. Since then he has grown to respect Senior Centipede.

Junior Centipede on the verge of death

After Junior Centipede emerged from the ground with Venus Mantrap at a restaurant, he grabbed a Hero Association's sponsor's child. Junior Centipede briefly mentions that he is looking for the sponsor of the Hero Association. Before he could grab the sponsor, Metal Bat grabs his coat and engages in a fight with him and his partner.[1]

Junior Centipede is seen laying on the floor severely injured. He praises Metal Bat for his strength, but still questions Metal Bat about how high Metal Bat is in the food chain. Before Metal Bat could finish Junior Centipede off, Senior Centipede erupted from the ground.[2]
