I agree with swayheaven about that bleach character. I don't see how Rukia looks up to him.
possible spoilers...and my opinion...
And I don't see how everyone so easily forgave him in the recent filler episode when he turned his back to everyone, and even attacked or killed multiple individuals. And for what? To protect his families honor...
Wouldn't it have been easier to just kill Muramasa instead?
There are so many I could name as worst anime main characters but, I would say the worst main anime character ever is Rossiu from Gurren Lagann, he is just so much of a freaking traitorous A-Hole near the end of the series I mean what he did near the end of the series made me so mad that wanted to run up to him and shoot him in the face.If you read the spoiler you will know why I hate him so much or if you watched series all the way through you should already know. I just could not stand when Rossiu turned on Simon so quickly and tried to put him to death just to calm the cries of the people just because the anti spiral came and where going to destroy everything and the people where looking for someone to blame for that , I mean he had beat the spiral king and brought them to the surface to be free yet all the people wanted him dead because of the anti spirals plan. Talk about a snake in the grass of a character and it didn't make it any better when the one chick tried to defend him by saying he agonized over what he did to Simon, that is no excuse for what he did.
