Despite only making their MCU debut recently, one character could be the key to solving a longstanding mystery.

Yet in the MCU, a Mjolnir-deprived Thor gained the upper hand against Hulk in the Contest of Champions, with Hulk only winning thanks to the Grandmaster's intervention.

After being thrown into the Contest of Champions, Thor's iconic golden locks are shaved, his breastplate is bare, and he loses Mjolnir. Nevertheless, this look resembles a specific comic book arc.

1) Spider-Man There is no one in the MCU more pure of heart than Peter Parker. After gaining incredible powers due to a spider bite, he takes to the streets of New York to help those in need.

Overall, I’d say that the Mjolnir moment is one of the best payoffs in the history of the MCU, not to mention one of Captain America's best moments in the franchise.

Marvel’s Eternals is currently scheduled to hit theaters this fall. When it does, Game of Thrones star Kit Harington will be making his MCU debut as Dane Whitman, AKA Black Knight.
