Sauron is a good candidate for an asshole pred. He's faced whole teams of X-men and done reasonably well, with his varied powers including superhuman strength, hypnosis and the ability to drain other mutant's powers.
If by herself, and in close quarters due to a surprise attack, and given that huge "beak", Sauron would have a good shot at sending Storm on a tour of his digestive tract. Dinosaur men have to eat too. 83
I drew this at MFF last week along with a burp/gloating page that I'll probably color tomorrow.
