Thor: Ragnarok - 7 Predictions For The Huge Surprise
5. Hela Raises The Dead
If it turns out that Hela gets her hands on the Soul Stone by the end of Thor: Ragnarok and actually defeats the Revengers, there's a distinct possibility that we might end up seeing the first hint of zombies in the MCU.
We already know that the Soul Stone is the tool to mastering souls, and being the Goddess Of Death, you'd think that Hela would use it to turn her own skills (and her own bountiful resources) into something to cement her power. And both a zombie army of dead Asgardians and tactical resurrections to mess with her enemies (like Frigga to haunt Loki and Thor or the other Valkyrie) would be great additions to her power-set.
It would be a bold move by Marvel to do that (especially as there's lots of desire from fans to see a Marvel Zombies movie), but it would fit with the hints that some dead characters might be revived to appear in Infinity War (like Crossbones).
