Avengers 4: 11 Things It Must Avoid

5. Valkyrie, Korg & Miek Are Still M.I.A.

One of Infinity War's most glaring omissions was the peculiar absence of Valkyrie (Tessa Thompson), Korg (Taika Waititi) and Miek, who were on-board the Asgardian refugee vessel which was summarily destroyed by Thanos at the start of the film.

The Russos have since confirmed that the trio did make it off the ship safely before it was obliterated, prompting speculation that they could show up in Avengers 4 to help take Thanos down.

Considering how these three characters became instant fan favourites, it'd be hugely disappointing if fans were left waiting until Thor 4 - which isn't even confirmed yet - to see more of them.

Will It Happen?: Nothing in Avengers 4's casting points to them appearing, sadly, and while it would certainly be easy enough for them to film a small cameo, it doesn't seem probable they're going to take part in the final battle.

Hopefully we're being trolled a little bit here and they'll turn up, but don't count on it.
