Loki

The likelihood is that Loki is going to be working alongside Thanos in the Infinity War movies. Having failed the Mad Titan in The Avengers, Loki anticipated being punished – and the only reason we can think that he hasn’t been is because Thanos has further plans for him.

Of course, Loki being Loki means he will probably have plans to double-cross the Mad Titan. Whether or not this will result in him saving the day and redeeming himself or going on to take over the universe on his own terms with the Infinity Gauntlet remains to be seen, but there’s every chance it could be him who defeats Thanos.

Tom Hiddleston’s character is incredibly popular and it would be foolish to think he doesn’t have a big part to play in the climax of Phase 3.

The fans would love to see a redemption storyline, however, and seeing Loki sacrifice himself to defeat Thanos would be awesome and a great way for him to bow out of the MCU.
