Happousai

八宝斎

Soun and Genma trained in their youth under the evil and perverted Happosai. This small man is THE master of Anything Goes Martial Arts (Musabetsu Kakutō Ryū). He is also a panty thief and a lecher of unbelievable proportions. In exchange for training, he berated and cajoled his two unwilling students into assisting him with his panty raids and peeping expeditions. More often than not, they ended up humiliated or injured in the process. Once they had finally completed their training (that is, escaped), they were able to move on with their lives. That is, until Happosai returned to select the next master of Anything Goes.
What he found upon reaching the Tendou Dojo was Ranma. Disgustingly enough, Happosai leered at the girl-type Ranma, even though he knows Ranma is a boy.
Taking up residence at the Tendou Dojo, he began extending Ranma's training. He also started expanding his panty raids into the surrounding neighborhood, as well as into the bedrooms of the Tendou girls.
Happosai is a tiny, yet immensely powerful martial artist. He usually wears a purple coverall, or occasionally a green bathing suit. When on his panty raids, he often wears a scarf as a mask. He is bald, with white fringes and a white mustache.
Happosai is a master martial artist and deceptively strong for his size. His only real weakness is his perverted nature. Happosai would leap in front of a speeding train for a pair of girl's panties. Often, he is foiled by a well-placed bra, and if he cannot lech onto some poor, unsuspecting girl, or Ranma, he goes into an addict's withdrawal syndrome. His power comes entirely from his lust, and he can be easily defeated by denying it.
Happosai is master of many magical martial arts attacks, although many are really just special effects. For example, his world-famous "Happo-dai-karin" (Happo Fire Blast) Technique is really just a firework and a match. He does, however, possess several powerful special energy techniques, as well.
