If there’s one thing we’ve learned from years of reading comics, it’s that every character doesn’t need their own solo series. While some popular sidekicks and supporting characters have been spun off into successful runs, they’re the exception, not the rule. As it launches its new streaming service Disney Plus, the entertainment giant would be wise to remember this where its Marvel properties are concerned. So far, we’ve had confirmation of a Loki series with Tom Hiddleston and plans for a Scarlet Witch series, as well as, a Falcon/Winter Soldier team up. With so many characters from the Marvel Cinematic Universe to play with, the possibilities for show ideas is endless. However, just because a character sparked with fans doesn’t mean they need their own show. Plenty of them could return in other capacities.

More than anything, the new series gives producers a chance to shake things up and let characters who normally wouldn’t meet up interact with one another. Outside of the confines of movie canon or weekly series with their own story arcs, we could see characters from Ant-Man hang out with S.H.I.E.L.D. agents. We also know that script restraints and scheduling conflicts often prevent actors from returning to the films, but guest appearances on a TV show might be more feasible. The universe they’ve already built allows Marvel to get creative, as fun new stories will help create even more interest in a crowded streaming field. With that in mind, here are 20 forgotten MCU characters that could return on Disney Plus.

20 PEGGY CARTER

It's true we’ve spent a lot of time getting to know Peggy, but we still feel like there's more adventures to discover. We could see the agent return in any project that needs to establish the founding of S.H.I.E.L.D., much the way she did in Ant-Man. She's also a major part of Captain America's life, so we assume she could also be involved in the possible Winter Soldier series.

As much as fans want to see Agent Carter revived, it appears that ship has sailed. However, as a character that's had a major impact on the MCU, Peggy can be the moral center in any hero or villain's story.

19 THE RAVAGERS

With the status of Guardians of the Galaxy Vol. 3 up in the air, Marvel will be looking at another way to visit the cosmic universe. Though we don't know who would be the main character of this story, you can't have an adventure in space without the Ravagers.

Guardians of the Galaxy Vol. 2 introduced us to the Ravager hierarchy, and the rules they must follow. Since we won’t see Michael Rooker back, and we doubt even Marvel could get Sylvester Stallone for a TV series, this would likely be new Ravagers we haven’t met yet. We don't necessarily need a whole show of them breaking the law, but they would be perfect as the comic relief supporting characters of another hero's show.

18 HYDRA

For years the comics have shown us that it’s impossible to tell any Marvel story without HYDRA. Following the events of Captain America: The Winter Soldier, Agents of S.H.I.E.L.D. spent several seasons focused on hunting down and eliminating the rest of HYDRA. Of course, that doesn’t mean we’ve seen the last of the operation.

No matter what hero or time period a series takes place in, HYDRA will always be there in some form, trying to make things worse. In fact, Agents of S.H.I.E.L.D. arguably had its best arc when it explored a world where HYDRA won and was running things. This means the MCU has plenty more stories about the villainous organization to tell.

17 THE REAL MANDARIN

When it was announced that The Mandarin would be the big bad of Iron Man 3, fans were interested. However, audiences were thrown a curve ball with the reveal that Ben Kingsley’s menacing villain was actually hired actor Trevor Slattery. The hilarious twist created another surprise when Trevor was apprehended by the real Ten Rings in the one shot All Hail the King.

This means there is a real Mandarin out there somewhere. While we may not get to see Trevor again, as Kingsley is an acting legend with a busy schedule, we can certainly see the real Mandarin appear as a shadowy figure manipulating events across several series. It’s way too big of a character and plot thread for the MCU to never revisit.

16 CHRISTINE EVERHART

Since her quick appearance in Iron Man, Christine Everhart has quietly become a consistent member of the MCU. As the journalist who often covers the actions of the various heroes, she puts the stories into a real world context. She’s basically the Soledad O’Brien of the MCU.

The WHIH Newsfront videos began as marketing for upcoming movie releases, but they actually help ground the outrageous events of the films. We’re not saying we need an MCU version of The Newsroom, however, there’s bound to be fallout from Infinity War and Avengers 4 across the entire universe, and perhaps Christine can be there to cover it.

15 LUIS, KURT AND DAVE

As funny as Paul Rudd is in Ant-Man, whenever he’s on screen with Luis (Michael Pena), Kurt (David Dastmalchian) and Dave (T.I.) he becomes the straight man. The trio have often bragged about their criminal exploits, so seeing them actually breaking into places from time to time would be fun.

As hilarious as the three of them are, they also only work in small doses, so we don’t need to follow them full time. However, as the supporting characters to other heroes they would work perfectly. Their take on discovering more of the superhero world would be endlessly entertaining and definitely lighten up the tone of any series.

14 THE GRANDMASTER

If we’re being honest, we’re not exactly sure how or why we would see more of The Grandmaster, we just know more Jeff Goldblum is always a good thing. As the character makes no sense outside of Sakaar, he would definitely be comic relief.

Marvel gave us a taste of what this could be in the video where he moves in with Thor’s roommate Darryl. Perhaps he pops up around the MCU in ridiculous moments trying to learn how to live on Earth? Sporadic appearances that possibly take place away from the movies would give Goldblum the freedom to take the character in whatever crazy direction he wants.

13 DAMAGE CONTROL

Once upon a time, ABC was developing a Damage Control series, but that didn’t make it very far. Marvel ended up using Damage Control in Spider-Man: Homecoming. As it turns out, the government agency has been working behind the scenes since The Avengers. Apparently, anytime there’s been mass destruction from a huge battle, they’ve shown up to collect alien artifacts and keep things contained.

Considering how much collateral damage there often is in the MCU, it doesn’t take much to imagine a team that shows up in different series, fixing superheroes’ mistakes. We don’t really need to get to know them, they can just be working in the background, occasionally offering assistance.

12 THE KOENIGS

Captain America: The Winter Soldier changed everything for Agents of S.H.I.E.L.D. Among the many characters its aftermath introduced was Patton Oswalt as Eric Koenig. He was an agent who worked closely with Nick Fury and helped Coulson’s team find a new base to reestablish themselves.

Following Ward’s attack on Eric, viewers were later introduced to his brothers Billy, Sam and Thurston. The Koenigs always seem to be involved in some secret project that only they can be trusted with, so we could certainly see them featured in other classified operations away from S.H.I.E.L.D.

11 GLENN TALBOT

Before his tragic end on Agents of S.H.I.E.L.D., Glenn Talbot was an interesting addition to the MCU. He initially had an unconditional mistrust of all things S.H.I.E.L.D. or Inhuman related. However, the more he worked with Coulson and the team he learned to understand them.

When we didn’t see him with Coulson, we assumed he was off fighting other threats in the MCU. With this in mind, we could see him in that capacity on series that take place at a different point in time. They could even drop subtle hints about his sad fate. It’s always fascinating to see the same events from a completely new point of view.

10 SHARON CARTER

In the comics, Sharon Carter has a long and storied history as a S.H.I.E.L.D. agent fighting various international threats. In the films, we've only just scratched the surface of her career as Agent 13. In Captain America: Civil War, she was working for the CIA while secretly helping Steve.

With Chris Evans’ portrayal of Steve Rogers likely coming to an end, we don't know where that leaves Sharon. However, the best place for her story to continue is in the possible Falcon/Winter Soldier series. She would be the perfect government liaison or secret partner for the unique duo. We already know that Emily VanCamp has fun chemistry with Anthony Mackie and Sebastian Stan.

9 ENOCH

As a Chronicom, Enoch is an anthropologist who examines races through time. He is the one who sends Coulson and the team to the future, then later helps Fitz find and rescue them. As an observer, he was reluctant to become physically involved in Fitz’s plan, but he ended up sacrificing himself so the team could escape.

Enoch mentions that he’s been on Earth for 30,000 years, which means he’s been there for everything. Surely, that would make him a likely choice to be in the background of many of the MCU’s most memorable moments. Coulson’s team encountered another Chronicom named Norm when they returned from the future, so if not Enoch, another member of their species could appear.

8 DOTTIE UNDERWOOD

As a graduate of the Soviet Union’s Red Room Academy, Dottie Underwood went toe-to-toe with Peggy Carter several times. To be sent after Captain America’s girlfriend, Dottie was obviously one of their top operatives, which means she probably interacted with other heroes and villains of the time.

She’s an interesting character worth more time, because she doesn’t question what she’s asked to do. She has no ambivalence about taking out her targets, and she does it with style. She’s so unapologetically bad we don’t need to see her as the lead of a series, but as someone else’s antagonist, Dottie is always entertaining.

7 CLAIRE TEMPLE

First things first, yes we know Claire could still show up on the remaining Netflix shows, however, let’s imagine a world where her break up with Luke Cage has set her on a path away from New York. From the moment we met Claire, she was slowly realizing that her calling was to help people with extraordinary abilities.

It’s a waste to use such a great character in one small corner of the MCU. What if Claire is the one who helps Wanda figure out her powers? Or she opens a new clinic and helps other heroes in the MCU the way she helped Matt, Luke and Danny?

6 BOBBI MORSE AND LANCE HUNTER

The exit of Bobbi Morse and Lance Hunter from Agents of S.H.I.E.L.D. was one of the series’ more emotional episodes. Sadly, the proposed spinoff wasn’t picked up and the duo didn’t return to the mothership. Hunter came back to break Fitz out of a military prison and we found out he and Bobbi had been helping others.

When Fitz left to save the rest of the team, Hunter said he and Bobbi would protect child prophet Robin. We’d like to see what this trio was up to while Fitz was on his long journey to the future. Maybe Robin foresaw the snap, which sent them into contact with the rest of the MCU.

5 HOWARD STARK

The Howard Stark we were introduced to in Iron Man 2 was described as a cold, uncompromising man, who spent more time with his inventions than with his son. Imagine our surprise when we met the young Howard of Captain America: The First Avenger and Agent Carter. He’s basically a '40s version of Tony.

We don’t need to see him every episode, as he’s a bit obnoxious and we can’t take too much of him at a time. However, as a recurring player similar to how he appeared on Agent Carter, we wouldn’t be opposed to following more of his adventures. We must make clear that we will also need James D’Arcy’s Jarvis to return, since there’s no Howard without Jarvis.

4 ROBBIE REYES/GHOST RIDER

Season four of Agents of S.H.I.E.L.D. introduced Ghost Rider into the MCU. Robbie Reyes made a deal to save himself after an awful car accident. He and the Ghost Rider went after evil men, making them pay for their crimes.

The last time we saw him, he opened a portal to take away the Darkhold. It was implied that Robbie and the Ghost Rider had come to an agreement to work together. We spent a lot of time learning about Robbie's life, so it would be interesting to see him work alongside other characters now that he's embraced his destiny. He's one of those characters whose powers can take him anywhere, so there’s a lot of storytelling freedom.

3 MIKE PETERSON/DEATHLOK

Mike Peterson was just a normal guy who wanted to protect his son. After he is turned into Deathlok by John Garrett, he helps Coulson fight HYDRA. He works in secret, occasionally sending messages back to the team.

As we’ve only heard about his missions from Coulson or Daisy, this is a chance to see what other parts of the MCU Mike has been involved in. For someone so central to S.H.I.E.L.D.’s work, we’ve haven’t really seen what Mike’s everyday life is like. Obviously, most of his work was focused on taking down HYDRA, but you’re telling us he couldn’t have been in Sokovia, New York or Wakanda?

2 LADY SIF

Turns out Thor: Ragnarok’s loss was our gain. Since Jaimie Alexander was busy filming her NBC drama Blindspot, she wasn’t around for Hela’s bloody take over of Asgard. We haven’t seen her since Thor: The Dark World, but we’ve heard that she’s off on assignment in other parts of the galaxy.

While Alexander may not be available for a full time return to the MCU, she may be able to occasionally show up and help other heroes with their adventures. She’s been absent for so long that she could be anywhere, doing anything, so there’s no end to what stories she could be featured in.

1 HOWLING COMMANDOS

As Captain America's fighting squadron, the Howling Commandos are one of the MCU's most tight knit teams. After Steve rescued them, they very quickly made a name for themselves taking down HYDRA bases.

Once Steve woke up in the present, we didn’t see them in the movies again, though an appearance on Agent Carter showed us they were still fighting the good fight. If Disney Plus has a show set during WWII (and we think they should), the Howling Commandos should definitely be featured. Like most sidekicks they only need to show up every once in a while to fight bad guys and make witty jokes.
