Marvel Studios' most recent Disney+ series may have come to an end, but there are plenty of upcoming MCU TV shows in development.
10Stephen Strange’s Doctor Strange
Doctor Strange & Agatha Harkness Are Both Powerful Sorcerers
Not much is known aboutAgatha Harkness' MCU history, butit’s likely that she has crossed paths with Masters of the Mystic Arts at some point prior toWandaVision. Agatha’s connection to the world of magic means the MCU’s most notable sorcerer, Benedict Cumberbatch’s Doctor Strange, could easily appear inAgatha All Along. AfterDoctor Strange in the Multiverse of Madness, Strange is on a journey to thwart incursions, but could return in the MCU’s Phase 5 if necessitated by the events ofAgatha All Along.
Doctor Strange has been set up as a key Multiverse Saga hero, but hasn’t been seen since 2022.Agatha All Alongpresents the perfect opportunity to advance his storyline. Additionally,Agatha Harkness was in possession of the Darkhold for some time beforeWandaVision, and the Book of the Damned played a huge role inMultiverse of Madness, so Doctor Strange could find Agatha as a means to learn more about the book itself.

Benedict Cumberbatch has portrayed Doctor Stephen Strange since his eponymous 2016 film, Doctor Strange, and has been on quite the journey in the MCU.
9Vision
Vision Could Return To Westview In Search Of Wanda Maximoff
WandaVisionmarked the debut of a new version of Paul Bettany’s Vision, now with a sleeker, white design.WandaVision’sfinale saw White Vision and the fabricated Vision fight in Westview, with the former eventually having his memories restored, prompting him to fly away to locations unknown. While Marvel Studios has confirmed anewVisionseries for 2026,White Vision could return to Westview inAgatha All Along, perhaps attempting to retrace his steps and search for Wanda Maximoff.
Vision has had a tumultuous journey in the MCU since his introduction inAvengers: Age of Ultron. White Vision will presumably be trying to rediscover himself and recollect his previous life prior to his death at the hands of Thanos. Westview is an important location inWanda and Vision’s history, so his return to his former home is possible inAgatha All Along, setting up his upcoming MCU series.
Star Trek: Picardexecutive producer Terry Matalas has been hired as the showrunner of the MCU’s newVisionseries, set to release in 2026.
8Peggy Carter
Hayley Atwell’s Peggy Carter may be an unexpected addition toAgatha All Along, but she has a strange connection to Agatha Harkness and the world of magic in Marvel Comics that could constitute her involvement. Following her death from old age in in the comics, Peggy Carter was resurrected as Dryad by the sentient Cosmic Cube.As Dryad, Carter led the Daughters of Liberty, an all-female superhero group who were taught magic by Agatha Harkness, consisting of other heroes, including Shuri, Black Widow, and the Invisible Woman.
Agatha All Alongcould see the MCU’s original Peggy Carter revived and rejuvenated as Dryad, following her death inCaptain America: Civil War. This would be a fantastic way to continue Carter’s story, alongsideHayley Atwell’s recent appearances as Captain Carterin the Multiverse Saga. This could alsopay offAvengers: Endgame’sall-female team-up tease, bringing together the Daughters of Liberty instead of A-Force.
7Wong
Wong Is The MCU’s Sorcerer Supreme
While Doctor Strange may be the face of the Masters of the Mystic Arts in the MCU, it’s actually Benedict Wong’sWong who is the Sorcerer Supreme. This significant role in the world of magic means it’s very likely that Wong could make a cameo appearance inAgatha All Along, especially after his repeated appearances in several Multiverse Saga projects.Wong has been teased to be building a new superpowered team of his own, and Agatha Harkness could be a formidable addition.

She-Hulk: Attorney at Law
Wong fought against the Scarlet Witch inDoctor Strange in the Multiverse of Madness, has expressed an intimate knowledge of theDarkhold and Mount Wundagore, and is known to keep tabs on magic-users across the MCU. Just as he tracked down Donny Blaze inShe-Hulk: Attorney at Law,Wong could cross paths with Agatha Harkness inAgatha All Along,perhaps convincing her to use her magic more responsibly.
6Pietro Maximoff’s Quicksilver
Agatha Can Resurrect Beings From The Dead
Technically, theMCU’s version of Quicksilverhasn’t been seen since his death inAvengers: Age of Ultron, but it’s possible that a return could be due inAgatha All Along. Aaron Taylor-Johnson’s Maximoff may have only had a short-lived career in the MCU, butWandaVisionteased Quicksilver’s return in the form of Evan Peters. Though it was widely speculated to be confirmation of a multiverse Quicksilver, Peters' role was later revealed to be a ruse created by Agatha Harkness.
WandaVisionepisode 8, “Previously On,” saw Agatha Harkness display her ability to resurrect dead beings, as she brought a bug back to life to disturb Wanda Maximoff.She could repeat this resurrection process with Pietro Maximoff, perhaps as a means to seek redemption after tormenting Wanda in the MCU’s Phase 4. This would be a fantastic way to bring back Quicksilver in the MCU.
Major MCU Scarlet Witch & Quicksilver Origin Mystery Is Solved By Excellent X-Men Villain Theory
The MCU’s Scarlet Witch and Quicksilver could be connected to the X-Men if one major villain theory turns out to be true in Marvel Studios' future.
5Tommy Maximoff’s Speed
Agatha All Along Could Bring Back Another MCU Speedster
If Quicksilver doesn’t return to the MCU inAgatha All Along, it’s possible the series could bring back a different speeding superhero. Jett Klyne debuted asTommy Maximoff’s Speed inWandaVision, and while the illusory child of the Scarlet Witch and Vision was killed off in the Phase 4 series, he could be reincarnated as a new character in the MCU’s future. In Marvel Comics,Tommy Shepherd realizes he is the reincarnated son of the Scarlet Witch, andAgatha All Alongis perfectly primed to introduce him.
Following speculation that the reincarnated version of the Scarlet Witch and Vision’s other son, Billy Maximoff, will appear inAgatha All Along, Tommy Shepherd could join him. In lieu of Quicksilver, this could introduce another speedster into the MCU, and another potential member of theMCU’s upcoming Young Avengers team. By bringing back Speed,Agatha All Alongcould include another new powerful hero.
4Billy Maximoff’s Wiccan
Wiccan’s New Form Is Already Rumored To Appear In Agatha All Along
Along with Tommy Shepherd’s Speed,Agatha All Alongcould feature the return of Wiccan. Billy Maximoff was played by Julian Hilliard inWandaVision, inheriting some of the magical powers of his mother, the Scarlet Witch. Much like his brother, however, Billy Maximoff didn’t survive the events ofWandaVision, butAgatha All Alonghas been rumored to be includingBilly Kaplan, the reincarnated version of Maximoff, who may be portrayed byHeartstopper’sJoe Locke.
Both Billy Kaplan and Tommy Shepherd are prominent members of the Young Avengers in Marvel Comics, so their introductions inAgatha All Alongcould be a huge mark of progress for the upcoming MCU superhero team. SinceJoe Locke is already speculated to be portraying Billy Kaplan inAgatha All Along, it seems as though this return is all but inevitable. This could even open the door for the Scarlet Witch herself to continue her redemption arc.
10 Actors Who Should Play Wiccan And Hulkling In The MCU
There is no doubt that Wiccan and Hulkling are going to be introduced into the MCU, but it is still a mystery as to who will be cast as the couple.
3Kamala Khan’s Ms. Marvel
Ms. Marvel Has Been Forming The MCU’s Young Avengers
If Billy and Tommy Maximoff return in their reincarnated forms inAgatha All Along, Marvel Studios could be taking more steps to set up the MCU’s Young Avengers. The most recent Young Avengers setup occurred in thefinal moments of 2023’sThe Marvels, which saw Iman Vellani’s Kamala Khan approach Hailee Steinfeld’s Kate Bishop with the prospect of forming the team.With Wiccan and Speed potentially making their returns to the MCU, Ms. Marvel could track them down, too.
Ms. Marvel is one of the most exciting recent additions to the MCU, especially since she is the franchise’s first on-screen mutant, and the presumed leader of the Young Avengers team.It makes sense that Marvel Studios would want to bring super-fan Vellani back in as many upcoming MCU projects as possible, and recruiting Wiccan and Speed for the Young Avengers could constitute her appearance inAgatha All Along.
Kamala Khan also teased Kathryn Newton’s Cassie Lang, Ant-Man’s daughter, as a member of the Young Avengers inThe Marvels.
2Wanda Maximoff’s Scarlet Witch
The Scarlet Witch’s Return To The MCU Is All But Inevitable
Agatha Harkness' connection to Wanda Maximoff has made the Scarlet Witch one of the most heavily-rumored characters set to appear in Agatha’s upcoming series.Doctor Strange in the Multiverse of Madnessended with theScarlet Witch’s apparent death, which Marvel Studios has since confirmed. Nevertheless,Elizabeth Olsen has been long-rumored to be returning to the MCU, with Wanda being resurrected somehow, andAgatha All Alongis the perfect place for this to happen.
In Marvel Comics, Agatha Harkness is something of a mentor to the Scarlet Witch, and this relationship would be excellent to explore in live-action.Agatha did help Wanda come to terms with her past and embrace her identity of the Scarlet Witch inWandaVision, so this could continue inAgatha All Along. With the prospect of Wanda’s reincarnated sons appearing in Phase 5, too, the Scarlet Witch’s return is highly anticipated.

1Kang The Conqueror
Agatha Harkness Battled A Powerful Kang Variant In Marvel Comics
Throughout the Multiverse Saga,Kang and his villainous variantshave been set up as the MCU’s new primary antagonists, taking over from Thanos. Despite his prominence inLokiseasons 1 and 2, and inAnt-Man and the Wasp: Quantumania,Kang’s future in the MCU is uncertain because of Jonathan Majors' 2023 reckless assault conviction and firing from Marvel Studios.Agatha All Alongcould be a surprising place for Kang to be recast, however.
In Marvel Comics,Agatha Harkness' battle with Kang variant Immortus makes the villain’s return inAgatha All Alongall the more likely. Back in 1990, Agatha Harkness saved the Scarlet Witch from Immortus, and later helped the Avengers in battling the powerful villain. If Kang is involved inAgatha All Along, Agatha Harkness could begin to cement herself as a bona fide superhero in the MCU.
