no order

Ok well number 2 is a very unique battle I would say.

Hiei Vs. Bui (Yu Yu Hakusho)

This Battle was Unique in some ways but over all I enjoyed it not only because Hiei is my favorite character from YYH but because of what he does in the fight. I will post a link to the fight later on. What Hiei does is he fires his Black Dragon Wave at Bui well Bui repels the blast back at Hiei, well he welcomes it into open arms and absorbs the dragon to become the dragon itself and defeats Bui quite easily after that.
Bui said in the fight that the reason why he wears the heavily wieghted armor is not to protect himself from others but the opposite way around its to protect those people from him. He is a very strong guy considering he was the only one previously to put up a figth against Toguro.

Here is the fight.
