Happousai

As the founding patriarch of Anything-Goes Martial Arts, Happosai served as the master of both the Tendo and Saotome households. Despite his frail and diminutive appearance, his martial prowess and speed are astonishingly formidable. He indulges in stealing women's undergarments and harassment as personal amusements, behaving in a selfish and despicable manner, making him an unpredictable source of trouble whose true power remains unfathomable throughout the series.
