happosai

Character from Ranma 1/2, Tendou Souun and Saotome Genma's abusive master and the founder of Anything Goes Martial Arts (the anime, at least, goes to the extent of having him refer to his moves as "Founding School Anything Goes"), this ancient pervert is the by far most powerful fighter in the series and lives solely to sate his own desires, usually getting away with it due to being the powerhouse he is, and is a frequent source of trouble.
