Boy II Man

Boy II Man (ボーイ・II・マン) is the Stand of Ken Oyanagi, featured in Diamond is Unbreakable.

Appearance
Boy II Man is a muscular humanoid spirit clad in riveted armor with a pointed helmet resembling those worn by medieval knights. It lacks a lower body, instead having a cloud-like sphere at the bottom of the stand. The Stand always manifests itself coming out of the hole in Ken's cheek, made by the Bow and Arrow.

According to JOJOVELLER, its design is heavily inspired by one of 's manga.

In the colored manga, Boy II Man is portrayed as jade colored. In the anime, it is portrayed as grey, with the cloud being yellow.

Abilities
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.

Energy Theft
Boy II Man's power is to steal the energy of an opponent whenever Ken beats them in a game of (RPS).

If Ken proposes to play a game of RPS and the opponent formally accepts, Boy II Man sets up a best-three-out-of-five game of RPS with the following rules:


 * A draw nulls the round and it has to be played again until someone wins.
 * Every time Ken wins a round, he takes a third of his opponent's energy and Stand.
 * If the opponent manages to win three times, any of their energy that was previously stolen is returned to them and the game ends.

When Ken wins a round, Boy II Man appears to take away one third of the opponent's Stand power. For instance, it literally tears away a third of Heaven's Door body and absorbs it inside the hole on Ken's cheek. Rohan is unharmed by the energy theft, but the corresponding body part begins to tire and falls under the control of Ken who can move it as he wants.

Moreover, Ken also begins to acquire the same power as the Stand it is stealing. It allows him to undo one of Rohan's commands and resume his game. 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.

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. Additionally, the effectivness of the Stand is dependent on Ken's luck and skill at RPS, which is regularly shown to be quite low.
