SPOILER ALERT: Though if you still haven't seen Thor: Ragnarok we can't be friends.
Towards the end of the movie, after Thor has realized that he has to utilize the destruction of Asgard (Ragnarok) to defeat his evil sister Hela, she scoffs at him saying that he cannot defeat her. Unfortunately for Hela, Thor has a trick up his sleeve - the fire demon Surtur. As the demon bursts from the palace, Thor corrects her with a smug "I know, but he can." Memers have started to use these panels to depict the many secret weapons we've witness throughout history and pop culture. Be it Stalin defeating Hitler, or Sansa and Lord Baelish defeating Ramsay Bolton - this is a dynamic we can all understand. Plus, we're suckers for any Marvel memes. Bring it on.
