Thanos' army in Avengers: Endgame almost included Dark Elves. 1 / 8
They were previously featured in Thor: The Dark World. 2 / 8
But they could've been part of the final fight and working with Thanos here. 3 / 8
The idea was scrapped during development though. 4 / 8
This would've given Thanos even more forces to throw at the Avengers... 5 / 8
While possibly indicating he became their commander after Malekith was defeated. 6 / 8
This could've further shown his power in the galaxy. 7 / 8
But maybe the Dark Elves will return in some other way in the future instead. 8 / 8
