This man held hostages at Heartland Shopping Mall and demanded money and a helicopter in order to release them. He kicked a litterbot as a message. When Astral noticed he had a "Number", Yuma went to try to get it, but Kite Tenjo appeared and Orbital 7 stopped time. He had no other choice then but to Duel Kite. As Kite easily Summoned his "Galaxy-Eyes Photon Dragon", his "Number 56: Gold Rat" was defeated and he lost the Duel. When Kite used his Photon Hand to claim the "Gold Rat" card, he aged very fast as his soul was taken in process. When Yuma and Astral arrived, they found out it was too late and the "Number" was already taken. The criminal then said "Number Hunter..." several times in attempt to warn Yuma before time returned to normal.
The only shown card of his was "Number 56: Gold Rat".
