Come to think about, Huan the Wolfhound of Orome is the "uber" one.

I know this is off topic, but it seems at least mildly relevant since this is a discussion of Maiar (evil maiar, though). Huan the Wolfhound seems to have single-pawedly defeated many major enemies for the side of right, stealing the spotlight, so to speak. Huan defeated Drauglin, Carcharoth, destroyed Tol-in-Gaurhoth, killed Thuringwethil, AND HE EVEN DEFEATED SAURON (as the wolf-more-great) in battle on the Tol-in-Gaurhoth bridge. Don't you think that's like a huge advantage being handed to Arda by the Valar (I suppose it was sort of called for).
