3. Zemo

In 2016’s Captain America: Civil War, Daniel Bruhl’s Helmut Zemo managed to split the Avengers up without so much as laying a finger on any of them, courtesy of him being a master manipulator and schemer.

He was revealed to be a former Sokovian colonel and elite paramilitary death squad member, whose family had been killed as a result of the huge battle that took place between the Avengers and Ultron in 2015’s Avengers: Age of Ultron.

He will surely already have caught the eye of the Avengers’ enemies, but he’ll have further chance to impress them when he appears in The Falcon and the Winter Soldier later this year.

With that in mind, he could end up being recruited to a villainous team if one emerges in the Marvel Cinematic Universe.

He could be the team’s tactician, strategist and special ops expert, as his experience in the Sokovian army means he’s practically tailored made for such roles – and the fact that he has a proven ability to cause friction between the heroes of the MCU would only help matters within the team.
