But several villains have only appeared in one movie that deserves some love from Marvel, villains that are big players in the comics but don’t receive that same treatment on the big screen. Some characters just appear and then are never seen again or killed off in the movie they first appeared.

10The Leader

Fans often forget thatThe Incredible Hulkis a part of the MCU, this is because Bruce Banner was a re-cast and looked completely different by the timeThe Avengers Assemblecame around, but the second entry in the MCU is very much canon. Tim Blake Nelson’s Samuel Sterns was a cellular biologist tasked with finding a cure for Bruce Banner’s big, green, and angry other half.

At the end of the movie, audiences watch Samuel Sterns get infected with Banner’s blood and his head begins to mutate to transform him into the villain known as The Leader, a regular villain of the Hulk in the comics. But this is the last time he was seen. However, he istipped to return inCaptain America: Brave New World. Hopefully, The Leader will get the play he deserves and prove himself as a formidable foe.

9Taskmaster

Black Widowis one of theMCU’s entries that isn’t widely loved by fans, set in the past (during its release) and when fans already knew Natasha Romanoff was dead. For many, the movie just seemed pointless since it didn’t add much in regards to the overarching story, and that’s not to mention its villain just yet.

Fans were treated to a fan-favorite enemy from the comics, Taskmaster, a villain who has a photographic memory and can copy the fighting styles of the hero, theoretically, they cannot be beaten. However, Taskmaster was portrayed as a silent, almost robot-like version of the character, and it was not well received. The performance was emotionless, and the character deserved better, with her being freed from the Black Widow program she could well likely reappear in a future installment.

8Malekith

Wildly regarded as the worstMCUfilm,Thor: The Dark Worldeven has a lackluster villain to boot, Christoper Eccleston is a terrific actor but Malekith was the victim of poor writing and really didn’t bring much to the screen.

Completely forgettable, a Dark Elf and a mortal enemy of Asgard, he should have posed more of a threat in his quest for the Aether, the Reality Stone. Due to his death in the movie, it is unlikely that fans will see Malekith in the MCU again, which is a shame, if the character was in a better movie then maybe he could have been one of the MCU’s greatest villains.

7Crossbones

Brock Rumlow, AKA Crossbones first appeared inCaptain America: The Winter Soldieras a secret HYDRA agent and he had a great rivalry with Steve Rogers that was perfectly portrayed throughout the movie.

Malekith In Thor The Dark World

After being horrifically injured thanks to the events of the movie he donned his Crossbones attire and had a deep-rooted hatred for Captain America who he blamed for his injuries. During the opening act ofCaptain America: Civil War, Rumlow reappeared as the Avengers attempted to end his terror attack in Nigeria. Upon being captured by Cap he set off a suicide vest which was redirected into a building by the Scarlet Witch which in turn caused the events of the Civil War. Another villain which was killed off so soon, it would have been great to see this rivalry between Rumlow and Rogers throughout the MCU.​​​​​​, but Marvel Studios killed this character off far too soon.

6Kaecilius

Wasting Mads Mikkelsen on this character is just ludicrous,the antagonist of Dr. Strange, Kaecilius was hell-bent on allowing other dimensions into Earth, so he could potentially be reunited with his deceased wife and son.

The Ancient One opposed this and Kaecilius took to a life of evil and attempted to bring Dormammu to Earth, but this was prevented by Steven Strange. Mikkelsen’s portrayal was faultless, but there was a sense that the character should have done more and shown up in future movies. The sequel toDoctor Strangewas a perfect opportunity to bring Kaecilius back, but he was left in the one-movie-and-done pile.

5Darren Cross/Yellowjacket/MODOK

Darren Cross is unique in this list in he has become two villains in the MCU, first appearing as the villain in Ant-Man donning the guise of Yellowjacket, a villain with similar powers to Scott Lang. At the end of that movie he seemingly dies but as fans learned inAnt-Man & The Wasp: Quantumaniahe survived but becamethe comic favorite villain MODOK.

As a follower of Kang, MODOK helped rule over the Quantum Realm, but by the end of the movie he redeemed himself and then later died. Wasting such an iconic and menacing villain, turned it into a joke, which was a common problem of that movie. Not every villain needs to be redeemed, and some people should just stay evil, and not die in their second appearance.

4Justin Hammer

Justin Hammer’s dynamic inIron Man 2was perfect, a cocky sure of himself villain who was motivated by money and power. He is Tony Stark if he was not a good person. Sam Rockwell’s performance received stellar credits but has not been seen since theIron Mansequel.

Hammer was sent to prison, where he still remains as far as fans are aware, there is no reason why he couldn’t show up and attempt to take over Stark Industries with the man himself no longer alive. Armor Wars would be the perfect chance for him to reappear and really put a stamp on the MCU.

3Gorr The God Butcher

Gorr was the big bad inThor: Love & Thunder, in the movie’s opening scene, audiences learn of Gorr’s hatred towards gods and how he vows to kill them all. Yet, audiences don’t actually see any of this in the movie, and they only see him kidnap children in the limited screen time the villain gets.

Darren Cross In The MCU

Played by Academy Award-winning actor Christian Bale, there was scope to have an amazing and complex villain, but that is just not what was portrayed on screen, wasted and underused, Did he even butcher any gods?​​​​​​​

2Red Skull

The arch-nemesis to a certain Captain America, Red Skull was the leader of HYDRA during World War 2 and was the victim of disfiguration due to an unfinished super soldier serum, hence his red appearance.

There is no fault in Red Skull’s role inCaptain America: The First Avengerbut the character was not seen again until years later inAvengers: Infinity War. He has seemingly given up on his evil HYDRA-related crimes and become the keeper of the Soul stone. It was nice to see the character again but in this form, he is just not the same. Red Skull and Captain America went toe-to-toe for years in the comics, and it is a shamefans did not get to see that for long in theMCU.​​​​​​​

1Ultron

Feared in the comics as one of the main villains of the Avengers, Ultron was given the main villain status in his own movie,Avengers: Age of Ultron. But this was his only appearance,there is so much potential in the character of Ultron, but this has been left in the shadows.

Ultron did receive some love in theWhat If?series askingWhat If… Ultron won?This showed how powerful the creation of Tony Stark can be. Ultron needs to return to the MCU, but with Kang taking the limelight as the main player, fans may never see Ultron again which is a real shame as it is such a unique and interesting villain.
