Best Anime Villan!?

Gary MotherF*$%ing Oak definitely my favorite "villain" alright so he wasn't really evil...so I'd have to say Aizen is my runner up...but there's a lot of really great villains out there I just choose Aizen because even if he did "fail" he was still able to become immortal...and will probably return later on...I mean c'mon the dude basically became a god...I'm pretty sure getting locked up was also part of his plan...

DOnt no if Yuno Gasai was a villain but she was insane. can get move messed up then killing your self and then almost doing it again. Aizen is a good one to so is Griffith from berserk

Gary oak ? Tehahahahahaha ahahahaha haha ha ha aha ha ha. The boss of team rocket is the most badass villain. Giovanni. His very name sounds like Mafia. But srsly For me thats Aizen. Why ? He drinks tea and watches while one of his experiments (ichigo) evolve into a further level just because he has a natural scientific curiosity. Also he tried to become god himself. Pretty badass idea for a villain. Like whats more evilo than taking the thrown of the creator and become god, the devine being of existence itself, himself ? Now if Juha Bach arc gets animated (and I really hope so) then Juha Bach or yhwach might be a better villain than aizen. But since this thread says anime villain its aizen for me.
