IronStrange

IronStrange is the slash ship between Tony Stark and Stephen Strange from the Avengers fandom.

Canon
Tony Stark met Stephen Strange in the latest Avengers movie entitled Avengers: Infinity War. They were cold to each other at first and insulted and despised one another with their arrogant attitudes. They were both on an alien ship when it left Earth, and they were I the same group for most of the movie. But in some part of the movie where Tony is nearly killed by Thanos, Stephen was willing to give away the time stone in exchange for Thanos to not kill Tony.
