MCU: 10 Best New Villains Who Could Join Phase 4

1. Galactus

If Marvel are looking for a threat big enough to eclipse even Thanos for Phase 4, there's a ready-made option in the shape of iconic comic book villain Galactus. Who else but a world-eater would represent the biggest threat the MCu had ever seen?

Galactus could also provide a means to bring an alternate dimension Fantastic Four into the MCU too. Rather than giving them an origin (which hasn't worked twice now), they could come to Earth to warn of Galactus' impending arrival, after their own Earth is destroyed.

His size obviously represents a fairly large logistical issue for any film-maker (hence him becoming a cloud in the original attempt to adapt him), and he's the kind of threat that could sustain an entire Phase himself.
