Bryan came to the realization that his life was quickly coming to an end.  Two years ago, the Mishima Zaibatsu recruited Doctor Abel as its top scientific advisor.  When this happened, Abel abandoned Bryan without giving a second thought to the now-obsolete cyborg's well being.

Bryan knew that the only person capable of extending his life was Abel, his creator.  Bryan despised both Heihachi Mishima, the man who took Abel away from him, and Abel himself for abandoning him.

One day, Bryan heard news of The King of Iron Fist Tournament 4, and decided to enter the Tournament.  He entered knowing that it would probably be his final fight.  As he trained, Bryan sensed that his death was quietly approaching.

Despite his impending death, Bryan's physical strength did not diminish.  On the contrary, Bryan's muscles flowed with energy that made him more powerful than before.  Along with this new strength, Bryan developed an almost uncontrollable rage that also manifested itself in his outward physical appearance.

Bryan staked everything on this one hope — if he won the Tournament, he would become the head of the Mishima Zaibatsu.  More importantly, if Bryan defeated Heihachi  Mishima in the tournament, he could easily take total control over the Mishima Zaibatsu to do his bidding.

If all went as planned, Bryan would command Abel to modify his body to prolong his life.  This would also be an opportunity for him to upgrade his body.

It would be his opportunity to upgrade himself to the most powerful being in existence.
