Oh, initially I was thinking even less subtle than that.
Fred J. Dukes, a.k.a., the Blob, becomes the US President. By dint of his supporters' "worship" and his title making him "the most powerful man in the world", he claims godhood. Asgard's enemies see an opportunity and bestow upon Fred godly essence and a mystical weapon in exchange for his covert aid. Fred leaps at the deal and agrees. However, an unexpected reaction to the dark magic tints Fred's skin with a perinone hue, while his brown hair becomes flaxen. Caling himself, The Mega-Patriot, Fred joins the Thor Corps task force, but betrays them later, leading to Odin's death.
Of course, I later thought better of making the Blob a character in my story and turning the ultimate patriot into the ultimate betrayer. I'm thinking Red Wolf, Reno Jones, the Apache Kid or someone like that might be perfect characters to reimagine in a mythical role. (Did I mention that the story will take the Thors across time and space?)
