'''Colin''', known as '''Doruo Ai''' in the Japanese version, is a [[Ra Yellow]] student in the [[Yu-Gi-Oh! Tag Force|''Tag Force'' series]].

He belittles the thought of including [[Card Crush]]es in a Deck, thinking every card in a Deck should serve a purpose. That purpose being winning. In ''[[Yu-Gi-Oh! GX Tag Force]]'', he is the sole character that did not appear in the anime that has multiple Decks.
