Big Joe is a man who encounters the party at the most bizarre moments, all appearances have different roles. During the Aveh tournament he is a popular fighter, he makes you lose 5000 G in the Nortune Civil Block, he plays cards against you on Yggdrasil when you visit Thames, he is a prisoner in the Ethos HQ, while Shevat are under attack he is found in the air ducks thinking of his life and he is a dancer in the Level 2 area of Etrenank. In the end of the game he is both a music supplier in Nortune Battle Arena and a shop keeper in the ruins of Zeboim. A somewhat hidden fact in the game is that Big Joe was actually living at the Zeboim civilisation, and his real name was Joey Balboa. He was in fact a very famous man back then, a five-time hit movie star, NBA Player of the Match, Baseball Triple Clow, Wimbledon Grandslam and in the same year he won both the WWE Championship a Pulitzer prize. Unfortunately he fell at a prize ceremony, got brain damage and started to think he was Elvis. Somehow he was later locked in a nanoreactor and placed in suspended animation before Zeboim fell and woke up 4000 years later in the present day Xenogears era, and still thinking he was Elvis.
