Batman ( with no armor, gadgets or weapons) could defeat Bruce Lee in a fist fight.

I will begin my argument with a tale of the tape Bruce lee: Stands at 5'7 Weights 160 pounds Batman: Stands at 6'2 Weighs 210 pounds. Discarding all other aspects of fighting this is already a huge disadvantage to Bruce Lee. Not only is Batman a staggering 7 inches taller, but he outweighs him by 50 pounds. This will provide him with a greater reach than Bruce Lee and his striking power will also be inherently greater. Strength/Size As I just mentioned Batman makes Bruce Lee look like a boy with the overwhelming difference in height/weight. But in addition to this, it is important to remember that his weight is entirely muscle. Batman has shown incredible feats of strength such as bench pressing 1000 pounds raw ( The current World record raw bench press is 722) , Leg pressing 2500 (It is unclear what the current record is but this is presumably close) , kicking solid trees in HALF, tearing open a locked vault by the handle, and many more just astonishing examples of his elite strength. Bruce Lee on the other hand, while very strong an muscular, comes nowhere near this level. It has been said that he has bench pressed 300 pounds, but this is just useless in comparison to Batman's strength. This results in him having much lower striking and grappling power than Batman. Speed/Agility/Reflexes It has not been defined clearly how fast either fighter is. However we do know that batman is as fast, if not faster,than any elite sprinter. Again, while Bruce Lee is fast he again does not come close to this level of speed. Batman has been shown numerous times chasing down cars running from him and escaping so fast in smoke it appear he has vanished. I do believe Bruce has cat like speed, but it is just not on par with Batman. As for Agility, the two are about equal. Both have displayed their agility on many occasions with remarkable displays of parkour in the streets and dodging speedy opponents in fights. IMO they tie in agility. For Reflexes, they tie again, by showing us their ability to defend lightning fast attacks from multiple opponents at once. Enough said. Fighting Skill This is where it gets interesting. Batman has MASTERED 127 different martial arts. He is a complete fighting machine. I would give him the edge here because he knows the martial arts Bruce Lee knows to perfection, along with many Bruce Lee doesn't know. This makes him an overall more well rounded fighter just because he has so many techniques to pull out of his sleeve. The real component missing from Lee's game is his ground game. Once Batman gets him down, he will not be able to defend against his attacks properly. Experience Bruce Lee was primarily an actor. Not to say he couldn't deliver quite the as whooping every now and then, It's just that he never really did it to the extent that Batman did. Batman has been fighting people all his life, including those with superpowers. The guy has held his own against Superman and many other overpowered heroes. Bruce Lee may have been a fighter from birth as well, but he didn't have to fight people as good as the ones batman had to fight. My overview of the Fight. It is a quick, bloody fight, in which Batman overpowers him with his superior strength and skills. One punch that lands from Batman would snap his jaw right in two. If he can kick big trees in half, I cant imagine if he wanted to he couldn't do the same to Lee. Batman is just too big and too strong for Lee to handle. While Lee may be able to hold his own against him if they had similar strength levels, they clearly don't, and that will be the deciding factor in this fight.
