Captain America: Civil War
Doctor Strange (2016)
Guardians of the Galaxy Vol. 2
- While Yondu retains this trait from the previous movie, Kraglin didn't previously have this trope. A combination of his Ascended Extra status, many likable qualities, and emotional role in Yondu's storyline made him very popular among audiences, with many hoping he joins the Guardians as Yondu's successor. Yondu himself is even more popular than prior, with his many badass feats and memetic lines, to the point where many people have called his death and funeral one of the saddest moments in the entire MCU.
- Gef became unexpectedly liked by people in the executive department, and his death was made slightly less explicit for it.
- Peter's gym teacher, thanks to his funny lines and being portrayed by internet darling Hannibal Buress.
- Mac Gargan only appears in two scenes, but his potential to become Scorpion and his excellent portrayal as a psychopath has earned him many fans. It's helped by the fact that he's played by Michael Mando.
- Aaron Davis likewise has a similar amount of screen time, but he manages to have a pair of memorable and funny appearances, and a handful of Miles Morales fans especially like that his presence and one of his lines confirm that the future Spider-Man exists in the MCU. The fact that Donald Glover already has a built-in fanbase of his own certainly doesn't hurt.
- Darryl Jacobson, Thor's roommate from the Comic-Con video. Many fans are hoping that he'll be made canon.
- Heimdall retains this status from the previous films, and gets a beefier role this time to boot as the man single-handedly protecting the Asgardian civilians from Hela's army.
- Skurge is this as much as the comics version was, thanks to the movie adapting a version of his iconic Last Stand at Gjallerbru, with a great character arc leading to it that takes him from being a comedic buffoon to a tragically conflicted villain to a truly badass hero.
- Korg, an eccentric, good-natured would-be revolutionary played by Taika Waititi—what's not to love? His good friend Miek is also rather popular as well.
Black Panther (2018)
Avengers: Infinity War
- Out of all the Children of Thanos (called the Black Order in the comics), Ebony Maw (the only one named in dialogue, just as "the Maw") is considered to be the most popular. His telekinetic powers make him unique among his group who are primarily fighters, and his role as a Hammy Herald gives him the most fleshed out personality of all of the Order. Comic book fans were disappointed by him being the first of the Order to die.
- The Stonekeeper, AKA the new form of the Red Skull, appeared only briefly but was a massive hit with audiences thanks to his cool personality, mysterious powers and role, and the sheer surprise of seeing him back and in such a different form.
Ant-Man and the Wasp
- Sonny Burch is a popular minor bad guy played by frequent Ensemble Dark Horse actor Walton Goggins.
- Ghost proved to be a massive hit with audiences thanks to her sympathetic backstory, unique set of powers, and her costume. Everyone was thrilled that she not only averts the Superhero Movie Villains Die trope, but her possible redemption is hinted at.
Captain Marvel (2019)
- Goose the Cat is also popular given how she is a Badass Adorable alien that can spring tentacles at a moment's notice and hold entire pocket dimensions within them. Many who don't like the film as a whole still cite Goose as a positive aspect.
- Many viewers noted that Ben Mendelsohn's Talos continued the MCU's streak of compelling villains, for his charismatic interactions with the heroes and constant terror in response to Goose. This was heightened even more when it is revealed that Talos and the other Skrulls are merely desperate refugees seeking to escape the Kree despots that are revealed to be the film's true villains.
- Starforce member Minn-erva has a lot of fans as well, despite becoming a villain later on in the movie, for her looks and potential rivalry with Carol. Many were disappointed that she didn't have a bigger role in the movie. Her character likely being Killed Off for Real, followed by Gemma Chan moving on to play Sersi, make it uncertain she might come back.
- The rat that accidentally let Scott free is a Memetic Badass. As is noobmaster69.
- Though her role is pretty minor, Cassie Lang was welcomed by the fanbase in part because she welcomes her father back in open arms five years after thinking he died, and is now a lovely young lady. Oh, and of course, the potential for her to become Stature increasing by multiple magnitudes is a plus.
- By a similar token, Morgan Stark as the daughter of Tony and Pepper. She's also cute as a button and a Daddy's Girl, endearing her to the fanbase.
- Frigga's appearance in this film is well-liked, in part because the first two Thor movies barely used her before killing her off, and in part because she's able to get Thor back in the right mindset of being a hero in spite of his failings.
- Howard Stark has only a brief role, but his unknowing conversation with his future son has caused many to see him in a new and better light.
- James D'Arcy makes a brief appearance as Jarvis, to the utter delight of Agent Carter fans, in the first time a character/actor who originated in one of the MCU TV shows has migrated to the movies.
- Pepper Potts as Rescue was a point of praise for many, seeing her finally join in on the action with Tony as a Battle Couple was a real treat.
Spider-Man: Far From Home
- The statuesque female agent who demands Peter remove his clothes in a consistently haughty manner. (Being played by German model Toni Garrn certainly helps.)
- Dimitri, the no-nonsense, wetworks-esque S.H.I.E.L.D. agent tasked to be their tour guide/driver. He has two scenes and is gold as The Comically Serious.
- J. Jonah Jameson, once again portrayed by J. K. Simmons, is seen as one of the best parts of the film in spite of only appearing for less than a minute.
- Bettys popularity definitely went up after her appearance here thanks to being a Nice Girl who gets hilariously paired up with Ned.
