3. The Avengers & Guardians Of The Galaxy
Ok, so this team-up is a little bigger than some of the others mentioned here (it pairs up two teams rather than just two heroes for a start), but it has to happen in Phase 3.
Whether Thanos is heading to Earth or The Avengers are going into outer space, Earth’s Mightiest Heroes meeting up with the Guardians of the Galaxy is something fans have been dreaming about ever since Infinity War was announced. It’s not hard to see why; just imagine Captain America and Star-Lord fighting side by side and Iron Man trading quips with Rocket Raccoon!
It seems inevitable that this team-up is going to take place, but nothing has been confirmed just yet, and we may not get a firm idea until Guardians of the Galaxy, Vol. 2 is released.
