MCU: 10 Characters Who Will Definitely Survive Phase 3
3. Doctor Strange

Two years after being name-dropped in Captain America: The Winter Soldier, Stephen Strange confidently strode into the MCU. After his origin story, which bore similarities to the first Iron Man, he's now one of the most powerful (and magical) characters around, which should come in handy for Infinity War and its follow-up.
Why He'll Survive
Benedict Cumberbatch is, potentially, the MCU's new Robert Downey Jr. He's one of the most high-profile actors in the world right now, with plenty of charisma, making him the best suited of all the newbies to step into RDJ's shoes.
Furthermore, Stephen Strange is the perfect successor to Tony Stark. An arrogant, wealthy genius with interesting facial hair, he's a natural fit to lead the superheroes in a post-Thanos world, after helping deliver them to victory. Although it's not 100&, it's all but certain that Doctor Strange 2 is coming, which is likely to lead to Doctor Strange 3, and with team-ups and crossovers Strange should be a massive part of the MCU's future.
