Kate Bishop & Hawkeye: Passing the Torch Under the Shadow of Doomsday

Where We Left Clint Barton

By the end of Hawkeye in 2021, Clint Barton had done what he set out to do. He trained Kate Bishop, survived one more chaotic Christmas in New York, and left her carrying a version of the Ronin identity along with his trust. The finale sent him home to his family, seemingly finished with the compound, the team briefings, and the near-death missions that defined his Avengers years.

That retirement has held for years of real time and, as far as confirmed material goes, it still holds. Nothing has walked it back on screen. Yet fan theories rarely respect a quiet ending, especially when the next confirmed event on the calendar is a multiversal collision large enough to swallow entire timelines. With Avengers: Doomsday approaching and Robert Downey Jr. confirmed to play Doctor Doom, the question fans keep circling back to is simple: does a threat this size pull Clint Barton back into the field, not to fight alone, but to organize the younger heroes he already started training?

An Incursion-Sized Problem

Incursions are not a vague comic book concept invented for marketing copy. They are confirmed MCU canon, first named and visualized in Doctor Strange in the Multiverse of Madness. The film laid out two specific causes on screen: Wanda Maximoff's uncontrolled dreamwalking across the multiverse, and America Chavez's inability to control her own universe-jumping power. Either one, left unchecked, can crack the barrier between realities until two universes occupy the same space and one of them collapses. For a deeper breakdown of how that mechanic works, this explainer on MCU Incursions is worth a full read.

Avengers: Doomsday is expected to deal with the fallout of exactly that kind of collision, reportedly spanning multiple distinct realities colliding at once, a setup covered in more detail in this look at the three universes central to the story. When the fabric between realities is already this stressed, the MCU has historically leaned on its biggest possible roster: full Avengers lineups, Fantastic Four crossovers, and now, reportedly, a Doctor Doom problem too large for any single team to handle alone. That scale is exactly why a theory built around expanding the roster of active heroes, even informally, keeps gaining traction.

Doctor Doom Changes Every Calculation

Robert Downey Jr. returning to the MCU, this time as Doctor Doom rather than Tony Stark, is confirmed for both Avengers: Doomsday on December 18, 2026, and Avengers: Secret Wars on December 17, 2027. That casting alone reframes the stakes. Doom is not a street-level villain or even a single-universe conqueror in the comics; he is a character whose ambitions routinely scale to reality itself. Readers catching up on decades of comic history before the film releases can start with this beginner's guide to Doctor Doom.

If the MCU version of Doom is drawing power from, or defending against, a multiverse already fracturing under Incursion pressure, the fight stops being about one team saving one timeline. It becomes about which heroes are even left standing across which realities, and how many different versions of Earth's protectors need mobilizing at once. That kind of chaos is exactly the scenario theorists point to when arguing Clint Barton would not sit this one out, not as a frontline fighter anymore, but as someone experienced enough to organize it. That is the scenario where a name like Clint Barton stops sounding like a retired hero and starts sounding like a necessary one again, at least according to the theory.

Why Kate Bishop Is the Obvious Successor

Among every young hero the MCU has introduced, Kate Bishop has the clearest, most on-screen mentor relationship already established. Hawkeye spent six episodes building her from an eager amateur with borrowed gear into someone Clint Barton trusted enough to leave his legacy with, literally handing over a version of his identity by the finale. That is not subtext fans are reading into a knowing look. It is the explicit endpoint of her entire season.

The mentor and successor dynamic between the two of them is confirmed material, which is exactly why it makes such fertile ground for a theory rather than requiring anyone to invent a relationship from scratch. If Clint Barton has any reason to step back into a field role, even briefly, protecting the person he groomed to replace him is the most narratively coherent reason available. It also gives Kate a reason to be somewhere important when the multiverse starts breaking apart.

The Young Avengers Rumor, Unpacked

Here is where this article needs to be very clear about what is confirmed and what is not. A Young Avengers team, as an assembled, named, active unit, has never been confirmed in the MCU. What exists right now are individual young heroes scattered across different corners of the franchise, introduced separately with no on-screen team-up announced. Kate Bishop, along with other young heroes fans associate with a future roster, currently operates independently. Everything past that point is speculation built from casting patterns, comic book history, and the sheer number of young heroes the MCU has quietly stockpiled.

The theory goes like this: an Incursion-scale threat is exactly the kind of event that would force loosely connected young heroes into the same briefings and eventually the same fight. Clint Barton, already retired once and already established as a mentor figure, would be a natural choice to steady that group rather than lead a mission himself. It reads less like the Avengers reassembling and more like a veteran making sure the next generation does not get thrown into a multiversal war without guidance. It is a compelling read of the pieces already on the board, but it remains a read, not a leak.

A mentor's last stand is not about being the strongest person in the fight anymore. It is about making sure the people you trained actually survive it.

What a Last Stand Mission Could Look Like

• A quiet recruitment phase where Clint reaches out to young heroes individually, positioning him as an organizer rather than a headline fighter.
• A training or briefing sequence that mirrors his own arc with Kate Bishop, this time applied across a wider group instead of one apprentice.
• A deliberate moment where Clint steps back from the front line during the final confrontation, physically passing responsibility rather than only handing over a bow.
• A survival-focused role that uses his experience to get younger, less battle-tested heroes out of a losing fight alive rather than chasing a solo win.
• A public, symbolic gesture, such as Clint vouching for Kate Bishop's leadership in front of other heroes, formalizing the transition instead of leaving it implied.

Who Else Might Answer the Call

1. America Chavez, whose own uncontrolled power already triggers Incursions, giving her a direct personal stake in stopping the very threat driving this storyline.
2. Young heroes introduced through Disney Plus who have not yet been folded into a team setting, since the MCU has spent years setting up individuals without paying off a group dynamic.
3. Legacy-adjacent characters connected to existing Avengers, following the same mentor and successor pattern already used for Kate Bishop.
4. Street-level heroes whose skill sets fit a supporting, tactical role rather than a cosmic-scale power role.
5. Established, combat-trained characters from earlier MCU projects who have stayed on the sidelines since their introduction, giving the group more experience than a first-time team would normally have.

The Case For and Against

Where This Leaves the Franchise

Whatever actually happens on screen, the underlying pattern is hard to ignore. The MCU has spent multiple projects establishing young heroes without giving them a shared mission, and it has spent an entire limited series establishing one mentor and successor relationship in explicit, textual detail. Avengers: Doomsday is the first project with a threat large enough to plausibly justify bringing both threads together on screen, and this overview of what the film covers is a useful starting point for anyone catching up before release.

Until Marvel Studios confirms otherwise, the safest way to read this is as one of the stronger theories circulating rather than a locked plot point. Clint Barton coming back into the field for one more mission, specifically to organize Kate Bishop and whichever young heroes get swept into the fight, fits everything confirmed about his character and the scale of the threat without requiring a single leak to support it. That is usually the sign of a theory worth watching rather than dismissing outright.
