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. Collector has in the past aided the FBI in solving 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 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. His only other appearance was as one of the souls absorbed by "Destiny Hero - Plasma" and when "Plasma" was destroyed in Aster Phoenix's Duel with The D, his soul along with the others were passed on to the afterlife.
Doctor Collector runs a Spellcaster Lock Deck based around removing monsters from 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 effect damage ability of "Ebon Magician Curran".
