In his own story in Tag Force 4, he competes with the player against Carly Carmine and Luna in the Preliminaries, Misty Tredwell and Leo in the quarter finals, Crow Hogan and Akiza Izinski in the semi-finals and Jack Atlas and Yusei Fudo in the finals. For completing the story, the Player will receive a photo of himself, Mimicry and Takuya Ito (Georg) called "Tops Security".
In all the video games he is featured in (save Yu-Gi-Oh! GX Duel Academy), when opened for free Duels, Mimicry gives the player the ability to play against their own Decks, in a Mirror Match-style setup. Thus, to unlock Mimicry's own Decks, the player must complete Story Mode with him as partner and have all the cards in his Decks in the player's trunk.
