Thanos is certainly the most iconic Guardians of the Galaxy villain. Despite mainly being known as their opponent lately, he is completely out of their league. I don’t care how much of a genius Rocket is, he simply won’t be able to build something that can destroy Thanos. Thanos has abilities that are completely out of this world. It’s hard to picture him even taking 5 minutes to end this fight as one solid hit will do the trick. Thanos wins.
