Yea! Major crossover battle!

In the red corner, it's Renji Abarai from "Bleach". He wields Zabimaru. He's in full-bankai mode basically because I think Zabimaru in his huge cobra form is awesome. And it makes Renji fight at full strength.

In the blue corner, it's Kurama Minamino from "Yu Yu Hakusho". He wields Rose Whip. Really this guy can use any plant as a weapon in battle. But what's most awesome about him is the intellegence he uses to figure out how to win a fight. It's as though Renji is fighting Uryuu.

Neither opponent is going to give up on this battle easily, so who knows which dude will win.
