10 Characters Who Have Defeated Thanos
10. Thor
The God of Thunder has gone toe-to-toe with Thanos many times throughout history, and rarely has it ended well for the beloved Asgardian. Thanos is almost always a more powerful character, who bests Thor at his own game.
But on one particularly note-worthy occasion, things went a bit differently. In Thor Vol. 2 #25, Thor faces the Mad Titan and looks to be set up for failure once again. That is, until Firelord shows up, gifting Thor with a new set of Asgardian armor, forged by Odin himself.
Upon putting it on, Thor is able to hold his own against Thanos. The fight comes to an end when Thor sends Mjolnir crashing down on top of Thanos' head, reducing it to a purple bloody pulp. Of course, this was later retconned to be a clone of Thanos because, you know, comics. Nonetheless, Thor killed him, if only temporarily.
At least Thor from the comics knew the most valuable lesson of all: always go for the head.
