In Yu-Gi-Oh! GX Tag Force, Corey is often found at the volcano or the beach. He barely speaks in the Japanese version, and speaks robotically in the various localized versions. During duels, though, he speaks normally, although this is because of the game's pool of phrases shared by all Duelist 3 characters.
During the Tag Force tournament, he partners with Nova.
The player is able to give Corey sandwiches. The following tables detail how much he likes or dislikes the sandwiches.
