10. Surtur
While he has yet to make an actual appearance in the MCU, Surtur is scheduled to show up in Thor: Ragnarok, and I am BEYOND EXCITED.
Surtur is a huge menacing fire demon with a big fire sword, and he wants to end the world. That’s everything I like about Thor comics, wrapped up in one dude. Seriously, if you haven't already read Walt Simonson's all-time great Thor run, you really need to. The Surtur Saga, otherwise known by the much better title Ragnarok and Roll, is maybe my favorite Thor story ever. It's really darn good.
In it, Surtur storms Asgard in an attempt to obtain the Twilight Sword, with which he will end the world and usher in Ragnarok. Eventually, the only ones left to stop him are Thor, Odin, and Loki. And what ensues is an all-timer of a battle. The fact that three of the most powerful Marvel characters ever have to work together, and still barely beat him, tells you all you need to know.
Power Level: Nightmare fuel.
