2. Loki (Thor, The Avengers, Thor: The Dark World)

With no doubt, all other MCU villains have lived in Loki’s shadow. Tom Hiddleston’s Norse god of mischief was by far the best thing in Thor with and it was inspired to make him the central villain in the first Marvel team up The Avengers. In Thor: The Dark World, Loki continued to steal the show from Chris Hemsworth’s hero and ended that movie succeeding in his goal of taking the throne of Asgard disguised as his father Odin.

In a cinematic universe which has sometimes failed to nail its villains, Loki remains one of the greatest characters. His wit and charm equally balance his manipulative and scheming nature, making audiences root for him as much as Thor. There were probably a few people he cheered when he took the throne. Thor: Ragnarok could be his last film and we can only wait with anticipation as to what Loki will do next.
