10 Marvel Heroes That Could Join The Avengers After Infinity War

5. Doctor Strange

Doctor Strange has never really been a full time Avenger in the comics, but he has been heavily involved with the group on countless occasions. He was also a member of the self-described Illuminati - a suitably secret team comprised of the world's brightest minds - although that did remain unaffiliated from The Avengers during its relatively brief existence.

Strange will no doubt be reversing this trend during Infinity War, however, with full blown membership very much being on the cards for the character. We've already seen him in set-photos for the upcoming blockbuster, and the leaked trailer (which we'd never ever possibly encourage you to see for yourself, or anything...) even showed the Sorcerer Supreme helping Star Lord get to higher ground during a massive sequence involving Thanos' forces.

Strange has been tapped to take on the role that will, inevitably, be vacated by Tony Stark by the time Avengers 4 rolls along, which opens up the franchise to a whole new manner of possibilities. Indeed, while most threats that the group have faced so far have been either cosmic or science-based, Strange's presence would allow for some of the mystical persuasion to take place.
