This is a nagging question that many have had ever since Avengers: Endgame. At the end of the film, after the Avengers and company defeated Thanos, the superhero team was effectively finished. Tony Stark/Iron Man and Natasha Romanoff/Black Widow were dead, Steve Rogers/Captain America went back in time and returned as Joe Biden, Bruce Banner/Hulk was maimed, Thor left for space to pursue adventure with the Guardians of the Galaxy, and Clint Barton/Hawkeye went back to retirement in order to spend time with his family. While this was a fitting way to close the chapters on these heroes, their departures left a void that has yet to be filled by another team.

This has not happened so far in the Marvel Cinematic Universe (MCU). After the Avengers split up, which was not the first time since they first broke up in Captain America: Civil War, no one came forward to continue the team. This feels irresponsible since there are still threats going on in the world and beyond, so there is still a need for the Avengers. Also, part of the reason why Thanos was triumphant in Avengers: Infinity War was because the team no longer existed. You would think the surviving heroes in Avengers: Endgame would have at least given thought to continuing the team to face any future threats.
In the Marvel Comics, whenever there were a lot of vacancies in the Avengers, there would be a huge rush of heroes to fill the void of the departed Avengers to form a new roster for the team. The first time this happened with the Avengers actually was very early in the comic book’s run with issue number 16, where the OG Avengers Iron Man, Giant-Man, the Wasp and Thor left the team. This left only Captain America, who was the first recruit, to form a new team of Avengers with Scarlet Witch, Quicksilver and Hawkeye. Over time, heroes came and went as the make up of the tesm radically changed.

What is unusual about the MCU is that post-Endgame various superheroes operating solo in the films and TV shows often claim to be an Avenger, yet they are not part of an active team. We saw Spider-Man, Ant-Man, Falcon and to some extent, Hawkeye doing this in their solo films/TV shows. If there was an actual team of Avengers in the MCU after Avengers: Endgame think of how quickly the calamities would have ended for the heroes in their individual films and TV shows. Now it seems as if history is repeating itself as Kang has emerged as the next high-level threat following Ant-Man and the Wasp: Quantumania, although in Ant-Man’s defense, he believes that Kang has been killed. But we know better.
Why hasn’t there been a new roster of MCU Avengers, yet? It boils down to two reasons: Resources and leadership. With Tony Stark gone, there wasn’t anyone who could effectively bankroll the team. Sure, there is his wife, Pepper Potts, but as we saw in Spider-Man: No Way Home, Stark’s company landed in hot water with the authorities because of their drones that were used by Mysterio in Spider-Man: Far From Home. So, the company is probably not in the best financial shape to provide resources for an Avengers team. Once Iron Man and Captain America were written out of the MCU, there has been a lack of leadership in the MCU. Unlike that issue of Avengers #16, there is no Captain America or some equivalent to lead the way and put together a new roster.

Of course, this will change fairly soon with Avengers: The Kang Dynasty and Avengers: Secret Wars. It’s clear that a new team of MCU Avengers will emerge to face a threat that no solo hero can handle, namely Kang or Doctor Doom. This may start to happen with next year’s Captain America: New World Order, as the new Capain America/Sam Wilson, who has no super-soldier serum, is forced to create a new team of Avengers. The Thunderbolts could also serve as a catalyst for a new roster of Avengers. Made up of mercenaries, the Thunderbolts in their debut film will probably operate in a less-than-noble manner and prompt the creation of a new Avengers team for the MCU. It’s too bad the MCU version of the Thunderbolts could not more closely match the original comic book counterpart, but to keep the true nature of the team under wraps would be impossible for fans and the “surprise” reveal would lack the same impact as the end of Thunderbolts #1.
There have been recent rumors that the new Captain America would not lead the new Avengers and Spider-Man would do so instead. That is hard to believe for real-world reasons in that the Spider-Man film rights are held by Sony Pictures and it is unlikely that Marvel Studios would have the leader of the Avengers be a character they don’t own the rights to. It will be interesting to see who else will lead the team if not Captain America.

An interesting development that the MCU could do is have the Young Avengers become the de facto Avengers, at least briefly. We have seen many of the Young Avengers members like Kate Bishop, America Chavez, Patriot, and Stature appear in the MCU. Perhaps they will be the new Avengers led by Sam Wilson, or the team could be made up of the following: Captain America, the Hulk, She-Hulk, Ant-Man, the Wasp, Doctor Strange, Black Panther, Spider-Man, Shang-Chi, all three of the Marvels, and some members of the Eternals and even the Thunderbolts.
Part of the fun right now is speculating over who will be in the new lineup of MCU Avengers. The waiting for the revelation will be worth it as soon as the new team in the films rallies with the iconic battle cry “Avengers Assemble!”.
