Yu-Gi-Oh! ZEXAL episode 13: "The Number Hunter, Part 1"
|Number 56's holder|
This man held hostages at Heartland Shopping Mall and demanded money and a helicopter in order to release them. He even kicked an 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 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 "Goldrat" 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 "Numbers Hunter..." several times trying to warn Yuma before time returned to normal.
The only shown card of his was "Number 56: Gold Rat".
