In Yu-Gi-Oh! GX Tag Force, Deron can usually be found outside the Obelisk Blue girls dorm. He is interested in girls, and he suggests the player to bring a cute girl to duel with him next time if beaten.
The player is able to give Deron sandwiches. The following tables detail how much he likes or dislikes the sandwiches.
In Tag Force 1, his Deck is largely a more aggressive version of Colin's first Deck, but from the second installment onwards, Deron's Decks focus more on "White Magician Pikeru" and "Ebon Magician Curran", as well as their evolved forms.
