Masaharu Niou (仁王 雅治, Niō Masaharu?), known as "the Trickster", is able to completely copy the techniques and play style of other players, creating the illusion his opponent is facing another person. It isn't completely perfect, as there are moves that he cannot copy and he is limited by his own physical abilities. He often copies his doubles partner, Yagyuu, to confuse their opponents. He can predict the moves of his opponents up to ten steps ahead. He is voiced by Yūki Masuda in Japanese media, and played by Masataka Nakagauchi in the musicals.
