Avengers: Infinity War - 11 Things That Definitely Won't Happen
10. Dancing With The Devil
It's not just Death that Thanos is hanging out with during Infinity Gauntlet, but also the devil himself, Mephisto.
On the surface he appears as a sycophantic follower of Thanos, helping him learn about using and controlling the Infinity Gauntlet and offering advice on why his efforts to woo Death have failed. Underneath all that, though, he's really manipulating Thanos into a position where he can be defeated. Turns out you can't even trust the literal devil.
Like with Death, it appears Marvel aren't keen on having the devil appear, and there's not much room for the character anyway. Loki has understandably been mooted as a character who could fill in this role during the movie, and it's a part he'd no doubt do well, but there appear to be other plans for him. His relationship with Thanos hasn't been established enough, and although he'll hand over the Space Stone it'll be unwillingly, with Loki looking certain to be one of the movie's biggest casualties.
