Jinzo, known as Android - Psycho Shocker in the Japanese version, is an evil Duel Spirit of the card "Jinzo", who seeks to become a real person by taking the souls of those who summon him.
Jinzo's usual outfit consists of a long coat equipped with shoulder pads and spiked collar, bracelets and belt. His face features thick veins and signs of deformity with the greatest part covered by a mask. The optional "Amplifier" features a helmet inserting various needles.
A group of three students, including Torrey, unwittingly call him forth, in a forbidden ceremony. After Torrey's friends involved in the ritual suddenly vanish, and Torrey starts seeing Jinzo, fearing his safety, he informs Jaden of the recent events. After Jinzo's next appearance, Jaden proceeds to Duel him, defeating him in a Shadow Duel. Because of his loss, Jinzo is forced to give up his ambition of returning to life.
Jaden recalls his life-or-death Duel with Jinzo during a similiar Duel against Nightshroud.
