Boy II Man (ボーイ・II・マン, Bōi Tsū Man, also known as Boy II Men) is the Stand of Ken Oyanagi featured in the fourth arc of the JoJo's Bizarre Adventure series, Diamond is Unbreakable. Its power allows it to steal the energy from anyone who loses to its user in a game of Rock Paper Scissors.
Boy II Man is a muscular humanoid spirit clad in riveted armor with a pointed helmet resembling those worn by medieval knights. The Stand always manifests itself coming out of the hole in Ken's cheek, made by the Bow and Arrow.
In the anime Boy II Man is shown to have no lower half, instead being presented with a wispy or cloud like protrusion instead of legs, similar to a genie.
According to JOJOVELLER, its design is heavily inspired by one of Mitsuteru Yokoyama's manga.
Boy II Man is a Stand with no shown combat ability, and is centered around the game of rock-paper-scissors but is surprisingly threatening because of its ability to steal someone's energy through a simple game.
Boy II Man's power is to steal the energy of an opponent whenever Ken wins a game of Rock Paper Scissors[2] (RPS).
If Ken proposes to play a game of RPS and the opponent formally accepts, Boy II Man sets up a best-of-five game of RPS with the following rules:
Moreover, Ken also begins to acquire the same power as the Stand it is stealing. It allows him to undo one of Rohan's command and resume his game.[2] If Ken wins three times, Yoshihiro claims that he will gain the power of the stolen Stand forever and be free to use it in conjunction with Boy II Man.[4]
Boy II Man possesses an inherent weakness in that people are allowed to cheat during the game, enabling Rohan to regain his Heaven's Door during his first gain by using the invisible Shizuka to force Ken's scissors hand into a rock hand.[5]
