Obito. Cuz he's da man.
No hype, no bias, yet easily strongest person alive, arguably ever, and nearly in every1's top3.
Unleashed kyuubi on konoha=killed minato. Revived Juubi. Casually declared war on humanity.
Bossed around nagato, itachi, sasuke, whole akatsuki, kirikagure, now even madara, and is in charge of juubi.
Could have easily rule the world long ago, or kill any1 he wants.
And all of above just for 1 girl, bash all u want, imagine if he had better reasons.
Theory is never a practice.Thank lord madara for helping him do those things
