A Jack robot has appeared in every Tekken game, with the exception of Tekken 4. Though their appearance has changed throughout the series, they've always kept their iconic mohawk.
T 1P: Green tank top and green camouflage pants, black gloves with nine silver studs, a yellow belt, and black combat boots.
T 2P: Tan tank top with pouches strapped on the front and tan camouflage pants, black gloves with nine silver studs, a black belt, and black combat boots.
T2 1P: Mostly the same as T 1P, but the tank top is recolored to black, the gloves' studs have been replaced with a single inverted red triangle and the pants are recolored to olive green.
T2 2P: A black bodysuit covered in electronics covers his body, and sectioned steel covers his forearms.

T3 2P: A dark green, pale yellow, and grey bodysuit which is partially built into his head.
T3 3P: Gun Jack also has an outfit which makes him resemble Jack-2. Mostly the same as T2 1P, but the pants have a more woodland camouflage pattern. This outfit is unlocked when Gun Jack is played 10 times.
