He later became known as Heladoman (Ice Cream Man) and became a local wrestler. He competed to represent Peru in the 21st Chojin Olympics: The Big Fight and defeated the popular, but corrupt Giganteman to secure his spot. At his grandfather's deathbed, Heladoman was told of his true identity and thus he changed his name back to Benkiman.
At the 21st Chojin Olympics he fought against Kinnikuman. Kinnikuman eventually was sucked into Benkiman's toilet and flushed down. When someone is flushed down, they never return. However, Kinnikuman returned because he stuffed his shorts into the toilet causing it to back up. The back up resulted in Kinnikuman winning the match. Kinnikuman also saved the other Chojins that were flushed down Benkiman's toilet.
In the manga he is depicted with a coil of feces on top of his head, but the anime changed it to a water faucet.
