Avengers 4: 9 Surprise Cameos That Could Still Happen

4. The Surviving Asgardians

When we meet the Asgardians at the beginning of Infinity War, things aren't looking so rosy. Heimdall's on the cusp of death, destruction lies in Thanos' wake and Loki, of course, is killed in an instant. The whereabouts of Valkyrie, Korg and Miek - Thor: Ragnarok's breakout stars - are unknown however, and though they're likely to return at some point, the prospect hasn't been openly broached during Avengers 4's production.

Considering the significant parts they played in Taika Waititi's film, their deaths would've surely been depicted in Infinity War. That means they're alive, and with their refuge doubling as a massive spaceship, escape pods, transports and the sort had to be available.

The fates of Valkyrie, Korg and Miek were considered as spoilers by the Russos as well, so don't be surprised if they show up in Avengers 4 - potentially in the final act, which is said to feature a massive shot of all the heroes together.
