Marvel Studios has a lot on its plate heading into 2026. With Avengers: Doomsday shaping up to be one of the biggest crossover events in MCU history, the studio is also quietly building a television slate designed to expand the story and connect the franchise's remaining puzzle pieces — and one upcoming series in particular looks ready to step into a very beloved role.

Avengers: Doomsday Is Bringing Everyone Together

The excitement surrounding Avengers: Doomsday (2026) continues to grow, and for good reason. The film is expected to unite an enormous roster of characters from across the MCU, making it one of the franchise's largest crossover events to date. Most notably, Robert Downey Jr. returns to Marvel — not as Tony Stark, but in an entirely new role as Doctor Doom.

The confirmed cast is staggering in its scope. Joining Downey are Chris Hemsworth as Thor, Anthony Mackie as Captain America, Letitia Wright as Shuri, Florence Pugh as Yelena Belova, Sebastian Stan as Bucky Barnes, Pedro Pascal as Reed Richards, Vanessa Kirby as Sue Storm, Joseph Quinn as Johnny Storm, Ebon Moss-Bachrach as Ben Grimm, Patrick Stewart as Professor X, Ian McKellen as Magneto, James Marsden as Cyclops, Rebecca Romijn as Mystique, Alan Cumming as Nightcrawler, Kelsey Grammer as Beast, Channing Tatum as Gambit, and Chris Evans returning as Steve Rogers.

What Happened to Loki Season 3?

Few Marvel series resonated with audiences quite like Loki (2021). The third live-action MCU series on Disney+, it quickly distinguished itself through its blend of humor, emotional depth, time travel, and Multiverse concepts. More than anything, it gave Tom Hiddleston's Loki one of the franchise's most satisfying character arcs — transforming the mischievous villain fans first met years ago into someone willing to sacrifice everything for the greater good.

By the end of Season 2, Loki's story reached what felt like a natural conclusion, as he accepted an extraordinary new responsibility tied to the Multiverse itself. That ending has left many fans wondering what comes next for the character. For now, though, there are no signs that a third season is in development. Instead, Marvel appears to be moving its television lineup in a new direction.

Enter VisionQuest

Rather than trying to recreate exactly what made Loki work, Marvel is introducing another character-driven science fiction series built to deliver a similarly imaginative experience. That series is VisionQuest (2026), which picks up the story that began in WandaVision (2021).

Paul Bettany returns as Vision, embarking on a search for the memories and identity he lost after S.W.O.R.D. transformed him into White Vision. The series premieres on October 14, 2026, and also stars James Spader as Ultron, alongside Todd Stashwick and Ruaridh Mollica.

While Marvel has kept many details close to the chest, early footage points to a psychological sci-fi adventure centered on themes of identity, artificial intelligence, and reality. Vision's journey reportedly takes him into a simulated world inside his own mind, where he encounters AI personalities including Ultron, FRIDAY, and EDITH — a strange, imaginative setting that echoes the inventive concepts that helped Loki stand out.

The Parallels with Loki Run Deep

The similarities between the two series go beyond tone and setting. Both Loki and Vision died before returning through unexpected circumstances, and both heroes are left searching for purpose after their second chance at life. That shared emotional foundation gives VisionQuest a strong starting point for the kind of character-driven storytelling that made Loki so compelling.

The series also introduces Tommy Maximoff, Vision and Wanda's son, now living in a new body following the events of Agatha All Along (2024). Their reunion could redefine Vision's future and help him reconnect with both his past and his family.

Setting the Stage for What's Next

With VisionQuest premiering on October 14 — just weeks before Avengers: Doomsday arrives in theaters — the series looks well-positioned to help shape Marvel's next era. Questions surrounding artificial intelligence, alternate realities, and personal identity have become increasingly central to the MCU, making Vision an ideal character to carry those ideas forward ahead of the franchise's next major crossover.

Meanwhile, fans haven't forgotten about Loki. Chris Hemsworth's Thor never had the chance to reunite with the Loki he lost in Avengers: Infinity War (2018), leaving one of the MCU's most emotional relationships unresolved. Whether Marvel brings the brothers back together through Multiverse events, time travel, or some other unexpected twist, it's hard to imagine the saga concluding without giving them another meaningful moment.

For now, VisionQuest appears ready to inherit the role that Loki once held on Marvel's Disney+ slate. If it delivers the same blend of imagination, emotion, and ambitious storytelling, Marvel fans will have yet another must-watch series to look forward to on the road to Avengers: Doomsday.
