Which Anime Hero Will Win These Duels?

We love when a punch downs someone. Literally. Kiss the ground, ye cheeky rascal.

With so much focus on strong anime  characters, it comes as no surprise that we want to find out who the stronger one is. But it's never as easy is it? Two characters from different anime rarely ever get together to decide their fate. What if they did, though?

We have the strongest anime characters with us today. Fighting a duel. The takeaway is that you get to decide who, between the two fighting, will win the duel. 

P.S.: Emotional attachment is allowed to be the deciding factor.
