The Marvel Cinematic Universe has been lite on dragons. Shou-Lao the Undying doesn’t count, because he’s dead (as per The Defenders.)
Well, that’s about to change.
@MCU_Tweets has posted concept art from Thor: Ragnarok showing Surtur’s dragon (or one of them) which will appear in the film. Said dragon is also going to be featured in Disneyland’s “Guardians of the Galaxy: Mission After Dark” theme ride. In the artwork, Baby Groot and Rocket Raccoon are seen alongside him (which has more to do with the ride than with the Thor movie).
Behold, the gaping fury. And, yes, he (she?) breathes fire.
In the comics, Surtur is a demon who wages war against Asgard during Ragnarok.
Thor: Ragnarok will hit theaters on November 3, 2017.
