True. But reading a lot of different mangas and the sheer number of fights thrown at you in Bleach makes it hard to remember everything once in a while. I can live with it if it happens to me in Bleach though. If it were One Piece, that'd be something to worry about.
Damn right that'll be something to worry bout. I didn't know who he was by name, i could care less bout the fodder arrancar names, but the min i saw him it clicked. Pretty much every fight in OP's a memorable one.
