Carl P. Accio (カール・Ｐ・アッチョ, Kāru P accho), or Carpaccio (カルパッチョ, Karupaccho), is a power user and a member of the Robert's Ten. He has the power to copy another person's power. The condition is that he has to spend 24 hours within 10 meters of them. He used this to acquire the powers of all of the other members of Robert's Ten. He has two powers from outside the Ten which are the power to change the opponent's thoughts to a cell phone Text-message and the power to reverse one's position with the opponent's. He uses all of these powers in combat and may actually have had more, but it is unknown as he was knocked out by Ueki's Masshu. Carl is a very sneaky (yet ironically loud) type who isn't above underhanded tactics to get what he or Robert wants.
