Sovereign: "You exist because we allow it, and you will end because we demand it" Or ANY other line works brilliantly
Harbinger was also amazing: "Human, you've changed nothing. Your species has the attention of those infinitely your greater. That which you know as Reapers are your salvation through destruction."
Judge Bergan from FFXII is amazing too: "Too late and to their sorrow do those who misplace their trust in gods learn their fate."
controversial one now:
Hope Estheim from Final Fantasy 13. Yes his character is a whiney ***** for most of the game, but while the CHARACTER can be slandered, the way the voice actor delivers it is pitch perfect for every line. Except the awkward shouts and screams that always tend to happen in English-dubbed Japanese stuff
there was another one I was going to put here, but I have totally forgotten it.
