I think "awesome" is massively open to individual interpretation...if all you go by is power level, Marc Remillard and Aiken Drum (Pliocene Exile) more than qualify, but when you talk about emotional response I'd say a character like Nazhuret (Lens of the World) fits the bill much better from my perspective.
