Prototype Jack (often abbreviated to P.Jack) is the prototype of the Jack line of robots, built purely for strength. As a prototype, he lacked the refinement of the finished models; in Tekken, he resembled a roughly built, less human-looking Jack with tools in place of arms, while in all later appearances he resembled a typical Jack, although lacking the skin-like finish of the final build, instead having a chrome-like metallic finish and colored wiring visible on parts of his body.
Tekken[]
Player 1 outfit:
P.Jack wears green camouflage pants, with a black boot on his right leg and a large metallic boot on his left leg. His torso has a metallic finish, his left arm is human-like with pincers on the lower arm while a large yellow drill press replaces his right arm. He has the head of a Jack robot, albeit worn with patches of metal showing through the "skin", with blond hair in a Mohawk style.
This appearance is later seen in Jack-6's Tekken 6 ending where Jack-6 has remodeled himself and was discovered by Jane.
Player 2 outfit:
P.Jack now wears a metal exoskeleton decorated with red stripes. His right arm now has a mace in place of the drill, while he has a black pair of pincers on his left arm. He also wears black boots and a pair of sunglasses. The "skin" is now missing from the back of his head, exposing more metal.
Tekken 2[]
Tekken 2 sees P.Jack receive his trademark look of military clothing worn over a metallic finish.
Player 1 outfit:
P.Jack wears green camouflage pants and a plain light-green tank top. He also wears a pair of black boots, a green cap and sunglasses. His hands are covered by black wrapping.
Player 2 outfit:
P.Jack's Player 2 outfit is identical to his Player 1 outfit, except his green camouflage pants and tank top are recolored in shades of blue.
Tekken Tag Tournament[]
Player 1 outfit:
P.Jack wears an updated version of his Tekken 2 Player 1 outfit; his camouflage pants and cap are recolored a more subtle shade of green and his sunglasses now have gold frames. P.Jack retains the black boots, green tank top and black hand wraps from his Tekken 2 Player 1 outfit.
Player 2 outfit:
P.Jack's Player 2 outfit consists of tan-colored camouflage pants and a matching cap. He no longer wears a tank top, instead fighting bare-chested, although he still wears the black boots and hand wrapping of his Player 1 outfit. He now wears sunglasses with gold frames and blue-tinted lenses.
Tekken Tag Tournament 2[]
Player 1 outfit:
(See Tekken Tag Tournament Player 1 outfit)
Player 2 outfit:
His Player 2 outfit is a palette swap of his classic Player 1 outfit, but with tan pants and a white tank top.
- P.Jack's swimsuit DLC matches the majority of the other male characters with the exception of Lee, Bob, Wang, and Ganryu, and is made up of a fundoshi, available in three default colors (black, white and red), and a pair of matching tabi boots.
