how about ahriman? i know chaos corrupted marines are void from this list, but that's just it - ahriman created and performed the rubric of ahriman to prevent chaotic corruption, and it worked. to all intents and purposes ahriman is essentially a traitorous but non-corrupted astartes.

i don't doubt that his martial prowess probably doesn't compare to the rest of this list, but he's exceptionally intelligent and in terms of raw psychic power - he's unmatched...
