Batman Beyond Vs. Kid Muscle

East Vs. West pic Lucky #7 BatMan Beyond Vs Kid Muscle. Although character wise they are completely different they are both teenage punks (Believe it or not the manga says Mantaro (Kid Muscle) is only 14), they take on the legacy of their fathers (that's right Bruce is Terry's father... if you don't believe me watch Justic League Unlimited) , they both have hot yet sometimes reluctant girlfriends (Terry-Daina Mantaro-Roxanne (Rinko)) and they always get their asses handed to them yet they always win.
Who would win?

Should I really post my opinion if not let me know so you can vote on your own...
anyway Batman gets his Butt Busted (Get it Butt Busted... Butt Buster! )... Forget it... T_T...Holy cow!

KM: With my rice I like to have some cow, cow, COW.
It tastes so very good I don't know how, how, HOW
It's my favorite form of chow, chow, CHOW, WOOW, WOOOW... Eat now!
