Rick

Rick, an amateur duelist with a fetish for Dragon cards, was first seen at the very beginning of the KC Grand Championship in "Unwanted Guest". Rick engaged in a duel against KC DuelTek 760, but due to a mysterious hacker (whom later turned out to be Zigfried von Schroeder) he unwillingly had to face KC DuelTek 760 on its highest and most dangerous level. Luckily Yugi Mutou, who were close by, jumped in and took over the duel and eventually won due to combining the effect of Rick's Spirit Ryu and Heart of the Underdog, a card he gave to Rick shortly before the duel.
