Tekken 1 - Jack Arcade Mode (PS1) 

This version of Jack used to give me nightmares. Something about those red eyes and his overall disproportionate body.

It's interesting how Jack has been in Tekken since the beginning while also being a newcomer in every game he appears in. Before I confuse the heck out of everyone, let me explain. Jack as a character has been in Tekken since the beginning, but a different version of his character appears in every game he's included in.

Stage 1: Yoshimitsu in Venezia Stage 2: King in Chicago Stage 3: Kazuya in Windermere Stage 4: Michelle in Kyoto Stage 5: Law in Angkor Wat Stage 6: Nina in Stadium Stage 7: Paul in Monument Valley Stage 8: P Jack in Acropolis Stage 9: Heihachi in Kyoto
