One-Punch Man Wiki

Suppon (原始人スッポン, Genshijin Suppon) was a caveman who was found in ice and revived, and later escaped from the lab. He was killed by Sweet Mask.[1]


Suppon was a large, muscular, and light-skinned caveman. He had two black circles under each eye and very long hair that flowed down past his waist. He wore a headband, several ornaments, a black skirt, and three bracelets on each wrist.


Not much is known about him, but based on his immediate hostility towards all humans and inability to understand what Sweet Mask was saying to him, Suppon likely had a primal-like level of intelligence.
