Post a character you thought was gonna be a villain but turns out to be good

Alyss(Will of the Abyss) from Pandora Hearts
I thought she was evil because shes the one who took break's left eye,but in real she's just a lonely girl with full of creepy mga manika and a cat(cheshire cat) she just want to get out of the Abyss :(

Franken Stein from Soul Eater. I really thought he was a villain when he defeated Soul and Maka in this battle between them and was about to finish both of them when actually Stein was just testing them to see if either Soul or Maka were willing to protect and sacrifice themselves for their partners. So pangkalahatang Soul and Maka passed Stein's test

alak Ichimaru from Bleach.
He did back stab the whole Soul Society and the chick he loved but it turned out he only backstabbed everyone so he could destroy the guy who nearly killed the chick he loved when they were kids. Becoming a Shinigami, backstabbing everyone and dying trying to kill the bad guy was all for the chick he loved :'(

Ryou from Tokyo Mew Mew, he was still awesome though.

Ren/Len Tao from Shaman King.

Mami Tomoe from Puella Magi. I thought she was evil at first.
