-------------------- "As I got off the plane, a man said to me, 'Shane, we're glad to have you here in God's country'. So I said, 'If this is God's country, then Heaven must truly have a ghetto!" - Shane Douglas, 2001
The new Captain Marvel is probably second, though.
-------------------- No additives. No concentrate. You won't find this man pouring juice from a cardboard container, oh no! He squeezes his own hand picked Florida oranges and savors his extractions, pulp and all! He's Steven Regal - a Real Man's Man!
I've been collecting comics for years and no one comes even close. The Beyonder was actually a facet of an incomplete cosmic cube; Loki is not even close and even Mephisto bowed down to Thanos (see Infinity Gauntlet). This guy is so evil, he was even able to steal part of Galactus' dna and create a son for himself, called Omega, that was based on his and Galactus dna! Thanos is the only character in the marvel universe that everybody was leery of - from the lowliest hero to the cosmic heavyhitters like Eternity, The Living Tribunal, etc. He finally bit the dust though in the latest miniseries called "End of the Marvel Universe".
