Maybe it's just the self-deprecation in me, but Puri-Puri Prisoner is one of the few characters to make me laugh in an anime in the last 5ish years. I don't mean that as, I never laugh at stuff in animes, I mean that it was such an obvious stereotype that it actually made me giggle. I don't think anyone viewing One Punch Man, took that character seriously.... I mean its a comedy making fun of shonen's that.... well include characters like that all the time. So you could say in effect it's making fun of the people making fun?
Either way, the presentation was so over the top ridiculous I couldn't stop laughing. I gotta say though, even if he was super Uggo he was deffinitely in good shape. No one can really fault him for not fitting the idealized super hero body.
