Thor (comics)
Thor, a founding member of the superhero group the Avengers, often battles his evil adoptive brother Loki, a Marvel character adapted from the Norse god of mischief. He is among Marvel's most powerful superheroes. Many recurring characters in his stories are based on Norse Mythology. Apart from this main superhero, Marvel features a number of characters based on him.
Supreme (comics)
Supreme was introduced in issue #3 of Rob Liefeld's "Youngblood" limited series as a flip book story before he was spun off into his own series. His history varied; at one point, he was an angel of vengeance who quoted the Bible to justify his actions. At other times, such as when he defeated the Norse god Thor and took his mystical hammer Mjolnir, Supreme considered himself a god. Although the most powerful being in the Liefeld universe, he had his share of defeats: he was killed in the cross-title "Deathmate Black" series (published by Image and Valiant Comics), lost his powers in "Extreme Prejudice", and was killed by Crypt in "Extreme Sacrifice".
