Ichigo kurasaki and kisuke urahara :DD Urahara is lol

As for comic characters, my favorites are Nel on tiny version because shes pure gold, specially that scene with Dordonii with the puke made me laugh a lot. Same for Pesche Guatiche, oh god when he helped Uryu vs the Privaron Espada and vs Syazel Aporro I laughed so hard.

As for real real favorites, I dont have a solid one, but Hitsugaya is very damn cool and so is Byakuya, and I have always liked Urahara/Uryu/Ichigo/Ulquiorra.
If I had to pick one it would be Shinji Hirako though, the guy dresses very damn well and is all around a cool bad ass.

My favorite Bleach character is either Sosuke Aizen or Shinji Hirako. Aizen at the beginning seems to be nice and all, but soon after, he just turns evil and vanishes to the land of the Hollows, with the full intent of mutating them just to rule Soul Society. Aizen's also charismatic; how else did he get Gin and Kaname to follow him to Hueco Mundo? How else (besides fear) did he get the Espada to obey him?

As rey said, Shinji's a bad ass, and I would include that he used to be Aizen's superior (pre-Hollowfication), which just adds onto his value. His Shikai is so cool in the fact that it can invert the viewpoint of his opponent's world. I truly have nothing more to say.

My favourite character is probably Hollow Ichigo [when his eyes turn yellow/black and he gets a half-mask, etc] or maybe Captain Hitsugaya :D

knepachi and ichigo im simple minded

Uh...didn't Ichigo beat Kenpachi back in the Soul Society? Aw, whatever.

My favorite character is actually a three-way, between Hitsugaya, Soi Fon & Komamura.
