Appearance/Personality
It is a muscular spirit with a helmet resembling a medieval knight.

Abilities
Game of Fate: Boy II Man's strength is its weakness. As Rohan learned through using Heaven's Door, this Stand could drain the energy of another Stand user by playing a Rock Paper Scissors game and winning it. However they are strict rules to how this is played:
 * It can only play 5 matches.
 * If it doesn't win 3 times, it can't take all of the energy. It can, however, take portions of the energy in thirds representative of each of the 3 times it has to win.
 * If it loses can't help but return the 'energy.

Control: Boy II Man has limited control over his opponents Stand, allowing him to control that corresponding area, as shown when he makes Rohan punch himself after taking the right arm of Heaven's Door. Its unknown if Boy II Man can absorb several powers at once to enable its growth; if so its potential is unlimited as long as it wins each match.
