Doctor Collector

Doctor Collector「ドクター・コレクター」(Dokutā Korekutā) is a duelist with an IQ of 202 who duels with The D to claim the championship title in the Pro League. The Collector has the ability to read the minds of other duelists, and in the past, aided the FBI in solving card-related crimes while in jail because of his vast knowledge on the subject. While the whereabouts of his physical body after the Duel goes unexplained in the English dub, the fire caused by the "Ultimate Destiny Card" in the Pro League stadium is linked to his death in the Japanese version. However, The D believes it was in fact the shock of being defeated that proved fatal.

Doctor Collector's character is based on Hannibal Lecter from Silence of The Lambs. In the English dub, the Collector is voiced by Sean Schemmel, while Satoshi Tsuruoka takes the role in the Japanese version. In addition, he speaks like a wrestler in the dub.

Deck
The Collector uses a Spellcaster Lock Deck based around removing monsters out of play using Dimensional Fissure and then special summoning them all at once with Dimension Fusion to simultaneously trigger the locking abilities of his three Magician's Valkyria cards in addition to the Direct Damage ability of Ebon Magician Curran.
