Tekken 6: Bloodline Rebellion:

Bob, a stoic person at heart, took his dreams of becoming strong very seriously.

Since childhood, he was a celebrated martial arts prodigy, and since he was a pretty boy with an excellent physique, he was not short of fans. Despite his martial arts prowess, he was unsuccessful against opponents of larger builds. For this reason, Bob disappeared from the public eye, setting out to accomplish the difficult task of rebuilding his body, increasing weight and power without sacrificing speed.

Bob returned home several years later after he had finished rebuilding his body. His drastic change in appearance shocked and disappointed all who knew him. Simply put, he looked fat, and nothing more. They couldn't contain their laughter. His once perfect body was nothing more than a distant and pleasant memory.
