Thanos
Yes, Thanos is the biggest, baddest villain in the MCU but he hasn’t done all that much yet. Hopefully he and his Infinity Stones will live up to the hype come Avengers: Infinity War.
The Mandarin
Iron Man 3 adapted Iron Man’s nemesis with style, as Ben Kingsley was brilliantly cast. Sorry, what do you mean he isn’t the real Mandarin?! I have no idea what you’re talking about…
Zemo
He might not be anything like the purple-hooded baron from the comics, but Civil War‘s take on Zemo was a fascinating master-manipulator who successfully tore the Avengers apart.
Ego
Kurt Russel’s power-hungry Living Planet was a brilliant addition to Guardians of the Galaxy Vol.2. He had a personal connection to Peter and was the most powerful villain the MCU has ever had.
Winter Soldier
Bucky might be on the road to redemption now, but he was certainly a villain in, er, The Winter Soldier. The conflict between him and Steve was one of the most dramatic in the MCU.
Red Skull
We really wish Red Skull had been used more up to this point, but Hugo Weaving’s portrayal in The First Avenger is enough to leap the disfigured Nazi up to fifth place.
