However, it is undeniable how powerful Thanos was. With the Infinity Gauntlet, he is unstoppable, arguably the most powerful being in the Marvel Cinematic Universe so far. Even without the gauntlet, Thanos could still fight against multiple superheroes and they can barely make him hurt. Seeing the villain that powerful, fans have to wonder: what would happen if your superheroes could not unite? Can anyone in the MCU be able to stand alone to fight Thanos and even win against him? Luckily, some individuals can fill this role and give Thanos a good run for his money (given that these characters want to fight Thanos to begin with).
#1 Thor Odinson

Thor Odinson, almost defeated Thanos with all the infinity stones. He is the God of Thunder and got even more powerful when he awakened his abilities. He would be able to defeat Thanos easily.
#2 Scarlet Witch

Scarlet Witch was full of rage in Avengers: Endgame. She is wanted to take revenge on Thanos for killing Vision. She was going to defeat Thanos but he rained fire. In this case, he doesn't have his army, so Scarlet Witch would tear him apart.
#3 Surtur

Surtur destroyed Asgard, tossed Savage Hulk aside like a ragdoll, and slew Hela. If that doesn't make him capable of killing Warlord Thanos, nothing does.
#4 Odin Borrson
