Chuck

Chuck is the owner of the Card Shop within Duel Masters: Cobalt. He is only playable through a cheat code.

Description and Personality
Chuck is a middle aged clerk with brown hair and a beard. He does not have a pivotal role within the game's story, instead he merely runs the Card Shop where the player can trade and buy in-game booster packs.

Occasionally, he will have certain quests for some characters, depending on who you're playing, and even gives Trey a creature piece.

Trivia

 * Chuck, evidently, also loans out cards.
