Teams and organizations of the Marvel Cinematic Universe

The Marvel Cinematic Universe (MCU) is an American media franchise and shared universe centered on superhero films and other series starring various titular superheroes independently produced by Marvel Studios and based on characters that appear in American comic books published by Marvel Comics. The shared universe, much like the original Marvel Universe in comic books, was established by crossing over common plot elements, settings, cast, and characters. Over the course of the films and related media (such as Disney+ miniseries), several teams and organizations have been formed, each with different aims and purposes.

The Avengers are the central team of protagonist superheroes of "The Infinity Saga" within the Marvel Cinematic Universe. Created by Nick Fury and led primarily by Steve Rogers / Captain America, the team is a United States–based organization composed mainly of enhanced individuals committed to the world's protection from threats. The Avengers operate in New York State; beginning at Avengers Tower in Midtown Manhattan, and subsequently, from the Avengers Compound in Upstate New York.

The Children of Thanos were an elite team of powerful people who served Thanos as generals and agents. Thanos adopted six known children—Ebony Maw, Proxima Midnight, Corvus Glaive, Cull Obsidian, Gamora, and Nebula—and trained them in the ways of combat, turning each of them into a deadly warrior. Over the years, Gamora and Nebula would turn on Thanos, while the rest of his children continued to serve him faithfully.

In 2018, as Thanos began his crusade to acquire the six Infinity Stones, he sent his children to Earth to retrieve the Time and Mind Stones. Maw and Obsidian attempted to remove the former from Doctor Strange's Eye of Agamotto while Glaive and Midnight attempted to steal the latter from Vision. Five years later, alternate versions of the Children of Thanos from 2014 time-traveled to 2023 and participated in the battle between Thanos's forces and the Avengers, Guardians of the Galaxy, Masters of the Mystic Arts, and Ravagers. Obsidian and Glaive were killed during the battle, while Maw and Midnight disintegrated after Stark gathered the Infinity Stones and snapped his fingers. An alternate version shown in What If...? shows how Thanos lost the team to the Collector when he became good.

The team appeared in the films Avengers: Infinity War and Avengers: Endgame; as well as the Disney+ animated series What If...?, in which they are referred to as the Black Order.

The Dora Milaje, also known simply as the Dora, are an elite organization of female bodyguards and Wakanda's special forces. The current general is Ayo. Florence Kasumba portrays Ayo, a member of the Dora Milaje, in Captain America: Civil War, as a guard of T'Challa. They next appear in Black Panther. Florence Kasumba reprises her role, Danai Gurira portrays Okoye, and Sydelle Noel portrays Xoliswa while the unnamed Dora Milaje are portrayed by Marija Abney, Janeshia Adams-Ginyard, Maria Hippolyte, Marie Mouroum, Jénel Stevens, Zola Williams, Christine Hollingsworth, and Shaunette Renée Wilson. After Killmonger takes over Wakanda and seemingly kills T'Challa, the Dora Milaje reluctantly stand by him as they must remain loyal to the throne. After T'Challa returns, the Dora Milaje fight Killmonger, though Xoliswa is killed in the process. In 2018, the Dora Milaje join the Avengers in defending Wakanda from Thanos's forces., whilst they fight Thanos's forces again in 2023. In 2024, after Bucky Barnes breaks Helmut Zemo out of prison, the Dora Milaje pursue the latter, and eventually capture him before sending him to the Raft. Ayo advises Barnes not to return to Wakanda for some time, though he is able to ask them to create a suit for Sam Wilson.

They appeared in the films Captain America: Civil War, Black Panther, Avengers: Infinity War, Avengers: Endgame, and Black Panther: Wakanda Forever; as well as the Disney+ television series The Falcon and the Winter Soldier and What If...?.

The Fantastic Four is a world-famous team of four superheroes on Earth-828, consisting of Reed Richards / Mister Fantastic, Sue Storm / Invisible Woman, Johnny Storm / Human Torch and Ben Grimm / The Thing.
