MCU Phase 4: 10 New Characters With The Most Long-Term Potential

Phase 4 is reaching its mid-point, but it has already introduced multiple new characters to the MCU who are already beloved. The cinematic juggernaut is already full of intriguing and beloved heroes, but there’s always room for more, or so the head honchos at Marvel Studios think.

Each movie and streaming series in Phase 4 has featured at least one new character. They are all entertaining, but only a few have the potential to become crucial members of the MCU, joining the likes of Captain America and Iron Man. Their stories are only beginning, but they already show plenty of promise.

Kathryn Hahn’s deliciously evil Agatha Harkness was one of the highlights of WandaVision. The actress delivered a wickedly funny performance while still making Agatha feel like a very dangerous threat. Her interactions with Elizabeth Olsen’s Wanda were also perfect, and fans couldn’t wait to see more of her after the show ended.

Fortunately, Agatha will return with a spin-off show where she’ll be the star. Beyond House of Harkness, Agatha has the potential to become a major supporting player like Mark Ruffalo’s Bruce Banner. Agatha can be part of any future project that involves Wanda or Doctor Strange and might even show up in the upcoming Fantastic Four movie, as some fans know she’s Franklin Richard’s nanny.

Phase 4’s most experimental project, Eternals, received a mixed reception from critics and audiences. However, time will surely be kind to the film, especially considering the exciting new possibilities it introduced for the MCU.


Any future project needs to flesh out the Eternals more, but they still show great promise for the long run. The team will be tricky to handle because there aren’t many projects where they could fit seamlessly. However, the cosmic portion of the MCU is expanding quickly, and with the Guardians seemingly retiring after their upcoming third film, the MCU will need another cosmic group. Who better to fill that spot than the Eternals?

And speaking of Eternals, the titular team wasn’t the only ones making waves in the MCU. Kit Harington’s Dane Whitman had little screentime in the film, but the future looks very promising for his character. Dane is best-known as the Ebony Blade-wielding Black Knight in Marvel comics, and he has close ties to the Avengers.

The off-camera voice during Dane’s post-credit scene in Eternals belongs to Mahershalla Ali’s Blade, hinting at a potential team-up. Indeed, Blade and Black Knight seem like the best choices to lead Marvel’s supernatural corner, especially now that Doctor Strange in the Multiverse of Madness officially introduced horror into the MCU.


Disney+’s She-Hulk: Attorney at Law recently revealed its first trailer, attracting mixed reactions from critics and audiences. Most of their criticism took issue with the lackluster CGI, but there’s still time until the show premieres, meaning there’s still room for improvement.

The trailer hints that Hulk might train She-Hulk to follow in his footsteps as an Avenger. Bruce has been doing the hero thing for a while, and no one would blame him for wanting to retire and enjoy some hard-earned free time. She-Hulk is the most logical choice to take his place on the team. If the MCU ever does a proper version of A-Force, She-Hulk is also the ideal leader for the all-female team.


America Chavez made her debut in Doctor Strange in the Multiverse of Madness. The film presents her as a young girl discovering her powers, hinting that her true potential is still ahead of her. America learns how to control her abilities by the end, and she chooses to remain at Kamar Taj, training to be a sorcerer.

It’s unclear where America will show up next, but the most obvious choice is in the Young Avengers. In the comics, she is a prominent member of the team and a close friend of Kate Bishop, so it all falls into place. She could also return for the third Doctor Strange. Both projects would probably come in Phase 5, so it might be some time before fans see America again.

Speaking of the Young Avengers, the MCU introduced the team’s de-facto leader with Hawkeye‘s Kate Bishop. Played by Academy Award nominee Hailee Steinfeld, Kate is Clint’s new protégé and the second Hawkeye in the MCU.


Kate’s presence in the MCU sets up the Young Avengers; however, fans still don’t know when the project will materialize. Kate will be front and center when it does, considering fans already met her. Meanwhile, she will probably remain absent from the MCU, especially considering there won’t be a second season of Hawkeye.

Ms. Marvel will arrive in June, introducing audiences to Kamala Khan. The MCU made several changes to the character’s powers, and fans are unsure how they feel about them. Still, Ms. Marvel is one of the most important MCU shows from 2022 and will have major repercussions for future projects.

Kamala will also show up alongside Monica Rambeau and Carol Danvers in 2023’s The Marvels, becoming the MCU’s first all-female team-up. It’s unclear if they’ll become an official team or it’ll be a one-time thing, but Kamala’s presence on the big screen hints at big things for her, making Ms. Marvel even more important.


And while on the subject of The Marvels, Monica Rambeau will play a major role in the film. The character appeared as a child in the first Captain Marvel before showing up in WandaVision. She gained her powers from Wanda’s hex and could become one of the most powerful characters in the MCU.

Beyond her role in The Marvels, Monica could become part of the Avengers. If the three Marvels do end up becoming a proper team, then their cosmic journey would certainly warrant a third movie. The future looks bright for Monica, and fans can’t wait to see what’s next for her.


Fans seem to agree that Shang-Chi was a great addition to the MCU. Inexperienced but with plenty of heart to make up for it, Shang-Chi is a martial arts expert with ties to the Ten Rings organization.

Following the events of his movie, Shang-Chi wields the Ten Rings, a mysterious weapon of massive power that will come in handy for future appearances. Shang-Chi seems like a prime candidate for the new Avengers roster; now only is he an expert hand-to-hand combatant, but he has the power of the rings. A sequel to Shang-Chi and the Legend of the Ten Rings is also a real possibility, so the character isn’t going anywhere.

Natasha Romanoff’s death left a huge gap in the Avengers. She was the team’s sole female member and a crucial part of the Infinity Saga. Many fans wondered if the Widow’s place would remain empty, but Yelena Belova’s arrival in Black Widow cleared that up.


Thanks to Florence Pugh’s likable performance, Yelena became a fan favorite almost instantly. Her appearance in Hawkeye solidified her as arguably the best new character in Phase 4, and the studio certainly plans to capitalize on her popularity. With the Avengers missing a Widow, Yelena becomes the best and only choice to take over. Otherwise, she could join the Thunderbolts or even the Dark Avengers, should the MCU ever introduce them.
