Jinzo, known as Android - Psycho Shocker in the Japanese version, is a Duel Spirit of the card "Jinzo". This is a video game version of the anime character, Jinzo.
In Yu-Gi-Oh! GX Tag Force, Jinzo appears during Part 1 at the Forest after 11:00 PM. If you talk to him after beating the game, he will become your partner if you give him 60,000 DP.
In Yu-Gi-Oh! GX Tag Force 2, Jinzo appears in the last event of Alexis Rhodes' storyline at the Abandoned Dorm, teaming up with Titan.
Jinzo uses Occult Decks similar to his Deck in the anime - they feature "Ectoplasmer" and "Malice Doll of Demise" as a combination that achieves both effect damage and field control. He also uses his own card, and adds its support cards from Light of Destruction to his Decks in Tag Force 3.
