Well, let us pay tribute for the perverts of Animation. I could consider Master Roshi of Dragon Ball one considering he still chases tail when he can. Bulma though is a Flasher. But Happosai from Ranma 1/2 collects Panties and is an active panty raider.
This is a chance to let yourself chime in for characters who sink to all new lows. Venture Brothers actually had a pseudo Cameo of Caligula in Escape From the house of Mummies Part 2 and historically he was almost as Perverted as it got in real life. But the question is who is the uncontested master of perversion in Animation?
All genres count, Anime, Animation, and Cartoons.
