With a fifth Avengers film almost certainly on the horizon, the next edition of the superhero squad will require a leader, and Eternals presents Sersi as the ideal candidate. The Avengers, released in 2012, debuted the famed team of heroes, which would continue to grow as the MCU film franchise proceeded. The first three stages of the MCU, commonly known as The Infinity Saga, finished with the original six Avengers leaving their roles due to death, retirement, or joining a different role. While there are other suitable candidates for a new Avengers captain, Eternals demonstrates that Sersi seems to be ideal.
Following the events of Avengers: Endgame, the Avengers’ fate remains unclear. In Spider-Man: Far From Home, Betty Brant’s school news show and Talos asking Nick Fury how to answer people’s Avengers-related questions, this is humorously addressed. Shang-Chi and the Legend of the Ten Rings’ post-credits sequence, in which Wong, Captain Marvel, and Bruce Banner brief Shang-Chi, hints that The Avengers remain in some way. The squad will have to regroup at some point, and the post of leader will have to be replaced by a new hero.
Eternals features the titular group of Celestial-created guardians whose stated mission is to safeguard Earth from Deviants. The group soon discovers that their mission is to foster life on Earth in preparation for its eventual annihilation, as it nourishes a new Celestial in a process known as the Emergence. Because they had become attached to Earth’s human species, many of the Eternals violated their command, saving the world from catastrophe. Sersi, who became the Eternals’ de facto leader following Ajak’s demise, would be a perfect candidate to lead the next generation of Avengers due to her expertise, abilities, and benevolence.
Steve Rogers founded the Avengers after leading the Howling Commandos (also referred to as the Invaders) during WWII and proved to be one of the few individuals other than Thor worthy of wielding Mjolnir. Rogers possessed superhuman strength and was one of the MCU’s greatest hand-to-hand combatants, but it was his sharp tactical intellect and unwavering moral compass that sealed him as the Avengers’ spiritual captain. Sersi is the most qualified candidate to take Rogers’ place as the next leader after Endgame.
Sersi, being an Eternal, is older than mankind, having defended Earth and lived with humans for the majority of the species’ existence. Her Celestial-granted cosmic power makes her one of the MCU’s most powerful characters, and she specializes in matter transmutation, an extraordinarily strong ability to quickly convert things. Sersi shares Rogers’ generosity, feeling so protective of mankind that she defied her core mission of enabling the Emergence, maintaining the Earth, and stopping the birth of a Celestial (whose species created her).
Sersi was taken by Arishem the Judge (the supreme Celestial) at the end of Eternals, and while her current situation is unknown, she’ll certainly appear in another MCU title in the future. With the Celestials, Kang the Conqueror, and other multiverse dangers on the horizon, the Avengers will undoubtedly reunite in a fifth movie. Their new lineup is unknown, although Eternals establishes Sersi as the greatest likely replacement to Steve Rogers as the Avengers’ new captain.
