Bruce Lee or a Bruce Lee imposter, is a character that heavily looks like Bruce Lee, the famous Martial artist. The first time he appeared was in the 21st Budokai against Krillin, in which he beat the crap out of Krillin with his famous Dragon Stomp. Krillin simply got up and laughed it off in fear the Bruce Lee imposter forfitted the match. Later he was seen in west city charging fighters money to fight him, after defeating a man with a shaved head he takes on Goku and takes several hits to the face before giving up in the same fashion as he did aganst Krillin. He seemed to have gotten stronger, however when he is seen again his voice was not the same as before and he wears blue boxing gloves. When he fought Krillin it might have been assumed that he used kung fu, however when he fought goku a spectator says that he is a master of kickboxing. It's possible there has been two impersonators or likely he had gone through slight changes.
