The
Ultimate Lecher 
Ataru Moroboshi, the infamous lecher of Tomobiki High School, saved the earth from an alien invasion by beating their representative at a game of tag. Unfortunately for him, the girl he beat thought he wanted to marry her. From there, it all went downhill, with enemies rising left and right, his 'wife' blasting him with ungodly amounts of electricity regularly, and his life in general taking weird and ridiculous turns. He'll never pass up a chance to hit on (or get a cheap feel of, or just glomp) a pretty girl, and has been proven to be nigh indestructable (through sheer luck, most of the time).
