1. Kang

Kang the Conqueror!!! Lord of Time! Dude who changes clothes more often than a sitcom character trying to simultaneously manage two prom dates!

Honestly, Kang may have the best chance of actually showing up in Avengers 4. The Russos teased a purple glove and some set photos that made it look as though they were going to include time travel or extended flashbacks in the movie. Both of those point toward Kang.

Kang travels time in an attempt to defeat the Avengers and Fantastic Four, with the goal of ruling the future unchallenged. He’s used several names in his quest, including Rama-Tut, the Crimson Centurion, Iron Lad, Immortus, and too many more to list here.

But for Avengers 4, he'd just have to show up as the Lord of Time and mess around with key moments in Avengers history. That way, you'd still have scenes with Avengers who'd died in Infinity War, but you wouldn’t have to bring them back to life!

The MCU is so expansive that there are all sorts of time periods to visit.
