Bruce Irvin first appeared in Tekken 2 as an unlockable character. He was a cop who was assigned to investigate the Mishima Corporation. However, he wound up losing his memories after a plane crash caused by the Mishimas. In a twist of fate, he wound up becoming Kazuyas bodyguard. Bruce isnt the most standout member of the cast. However, there arent any other members of the Tekken cast who use Muay Thai Kickboxing as their primary style. While its important to always have the most iconic characters get some sort of representation in a fighting game, there is also a distinct need for diversity in fighting style among the roster. Granted, Tekken 7s newcomer Josie Rizal shares a few of Bruces moves, so perhaps she may in fact be a replacement for him. Bruce may not be a completely memorable fellow since hes only appeared as a playable character in a few games. Yet, he also adds a sense of realism to a cast chock full of ogres, devils, androids and cyber-ninjas.Likewise, he is essentially Kazuyas lackey. In a game where the Mishima clans past will be the focal point, it makes sense for some of the auxiliary characters related to them to get a turn in the spotlight.
