Villains are characters that typically propel the plot forward. This is precisely what MCU’s most interesting villains have done in the past. Without them, we wouldn’t know just how capable superheroes can be. This might be the reason why we like to rank the most powerful villains to exist in the Marvel Cinematic Universe.

And when it comes to villains, we think these are the best ones from the MCU so far:


Hela may be Thor and Loki’s sister, but her MCU debut took time, nonetheless. As it turned out, the character’s debut could have occurred in the 2011 film Thor. However, the character’s only appearance in an earlier version of the script was removed completely. Since Hela only appeared in the third Thor installment, there are many things you probably still don’t know about her even today. In fact, you may not even know why Hela would win against Thanos if they were to fight.


You know instantly that a villain will wreak major havoc when their name is present in the movie title. Just like Avengers: Age of Ultron. Not surprisingly, Ultron was also among the characters with the most screen time in this installment. Blacklist star James Spader was tapped to portray this villain that managed to infiltrate the Avengers Tower. Meanwhile, it’s possible that we haven’t seen the last of Ultron yet. That is, even if he died at the end of the film. In recent months, a Marvel theory has emerged that he’ll return in Marvel’s Phase Four.


Unlike other MCU villains, Mysterio doesn’t have powers. However, he is clever, even managing to fool people into thinking that he is from another dimension. Later on, however, Mysterio’s façade started to crack and for actor Jake Gyllenhaal, that’s what made the character interesting to portray. “Throughout the whole thing … there’s a real shakiness to certain things that he does,” he told The Hollywood Reporter. “Devising that plan was the best part of it.” Meanwhile, it might also interest you to learn that there are at least five things that they changed about Mysterio in Spider-Man: Far From Home.

Erik Killmonger

Killmonger is a villain who had personal issues with the Black Panther. As the son of Prince N’Jobu, he had a valid claim to the throne of Wakanda, something that T’Challa himself didn’t deny. The problem was nobody in the kingdom knew of his existence initially. In portraying the character, Michael B. Jordan noted that it was quite challenging as he explained to Pop Sugar that Killmonger is “a lot darker than what I usually have to prepare for.” Meanwhile, we can think of at 10 best Killmonger scenes from the film.


Thanos’s presence was teased in previous MCU films. However, the superheroes only come to realize his full brunt during the events of both Avengers: Infinity War and Avengers: Endgame. Thanos is nothing like your typical bad guy. Sure, he kills without mercy and the creatures his army has unleashed are quite menacing. Underneath it all, Thanos is convinced that he is just doing his part to help prolong the existence of the entire universe. And a villain who thinks that his actions are justified is far scarier than someone who just likes to do bad things to people.
