Doctor Strange: 9 Big Implications For Phase 3 And Beyond
7. Time Travel
Just as big as introducing magic, if not even bigger, is the fact that Doctor Strange also brings time travel into the MCU via the Eye of Agamotto.
Strange uses the Eye (confirmed in the movie to possess an Infinity Stone) at a couple of key points in the movie: to rewind the destruction in Hong Kong in the last fight against Kaecilius, and even better to create a time loop to defeat Dormammu.
Even more than magic, this gives Strange - and thus the Marvel Cinematic Universe - an out for any developments they suddenly need to rewind. Someone dies? Turn back the clock. Thanos defeats the Avengers? Rewind. (Unless he destroys the Eye, that is.)
It's a hugely powerful weapon for Strange to have in his arsenal, and it'll be interesting to see just how it's used, and what rules are created - what consequences will his meddling in time have?
