With Avengers: Doomsday set to arrive in 2026, Marvel Studios is quickly running out of time to actually build the Avengers. The teasers released already suggest the original Avengers of the Multiverse Saga will play a significant part, with Steve Rogers and Thor heavily pushed, but that wasnโt what we were led to believe a matter of months ago. We were told, in Captain America: Brave New World that this would be the first post-Endgame attempt to rebuild the Avengers, and that it would be around Sam Wilsonโs Captain America. Obviously, Thunderbolts* then threw an almighty spanner in the works, but even there, Samโs team was presented as the โmain Avengersโ, and Buckyโs the โNew Avengers.โ

Now that Cap and Thor are back, and with Mark Ruffalo, Tom Holland, and Jeremy Renner all expected to be back too, the question of who will actually make up Samโs Avengers is still unclear. Logically, youโd expect him to recruit the best available heroes, given the coming threat to Earth, but the connective tissue to allow that simply doesnโt exist, and thereโs no time to add it. Take Riri Williams, for instance, the perfect candidate to bring near-unrivalled technological genius to the Avengers, who is already on the radar of the Wakandans, and who absolutely wouldnโt be sitting out the fight with Doom. But thanks to the ending of Ironheart, it feels impossible for her to even be mentioned, let alone return.ย
Ironheart Created A Huge Devil-Shaped Problem For Doomsday

On paper, Riri is an obvious recruit: sheโs young, brilliant, and is still the most likely candidate to inherit Tony Starkโs legacy in a way that fits Marvelโs next-generation narrative now that Spider-Manโs story is headed in another direction. But thereโs a massive, devil-shaped problem: Riri Williams is no longer just Ironheart. Sheโs now under the corrupting influence of Mephisto, following the supernatural revelations at the end of her 2025 show. Because that is simply not a story point that can be casually brushed aside without cheapening it or making everything confusing.
So how does Marvel intend to juggle that? The short answer is it canโt. Avengers: Doomsday already looked dangerously overstuffed before we knew Steve Rogers was back, and if itโs under 3 hours, it will be extremely shocking. Between Sam Wilson leading the Avengers for the first time, the arrival of the Fantastic Four, a potential Thunderbolts standoff, Capโs return, Doomโs rise, and the ongoing multiverse crisis that will bring in the X-Men, there is simply no room for a subplot for Riri. Ironheartโs corruption arc needs more space to develop than Doomsday can shoehorn in between fan-service battles.
The options here are either to bring Riri back and ignore the demonic possession entirely (which feels impossible, but might also have to be done for James Rhodesโ Secret Invasion reveal if heโs also involved), or just not bring Riri back at all. The latter feels likely now, but will go down as yet another case of the post-Endgame story development being completely cast aside for the culminating event that should surely have tied it all together. Unfortunately, thatโs the situation Marvel has created, and while Ironheart wasnโt to everyoneโs taste, the fact that the next major MCU crossover will simply have to ignore the arrival of a villain as potent as Mephisto, and a character now as powerful as Ironheart, is ludicrous.
