Bleach: I'm pretty sure out of every villian victory no one succeeded more then Aizen. I mean not only did he complete his long, intrictated, complex manuvear of killing the council that governs Soul Society, control the laws so Ruika would get arrested/ be executed, make his own lieutant think her best friend killed him, obtain the Souyoku from inside Ruika's gigai and go into Hueco Mundo to power up all the hollows to follow him, but he pretty much owned every one he touched. Hitasaguya, Komamura, Renji... I mean he owned Ichigo, the main character with one freaking finger. And got away with that. How can you not call that a win?
