Avengers Assemble is an American superhero animated series based on the Marvel Comics superhero team known as the Avengers. Designed to capitalize on the success of the 2012 film The Avengers, the series premiered on Disney XD on May 26, 2013, as the successor to The Avengers: Earth's Mightiest Heroes.

It previously aired alongside Ultimate Spider-Man, Hulk and the Agents of S.M.A.S.H., and Guardians of the Galaxy as a part of the Marvel Universe block. Joe Casey, Joe Kelly, Duncan Rouleau and Steven T. Seagle, known collectively as Man of Action, developed the series and were executive producers on seasons 1 and 2.

The series ended on February 24, 2019, after 127 episodes over the course of five seasons, making it the longest running Marvel animated series. However, it is expected to be surpassed by Disney Jr.'s Spidey and His Amazing Friends following preemptive renewals for a sixth and seventh season in June 2025 and August 2026 respectively.

Plot Premise Falcon is the newest member of the Avengers. Falcon is the main eyes and ears of the viewer as he fights evil and saves the world with his teammates. The Avengers team consist of Iron Man, Captain America, Thor, Hulk, Black Widow, and Hawkeye.

Season 1 When Red Skull begins dying due to his imperfect Super Soldier Serum, he allies with MODOK, who uses Hydra technology to transfer his mind to Captain America's body. After his defeat by a reassembled team of Avengers, Red Skull steals Iron Man's armor to use its life support system. Red Skull attacks the Avengers at their mansion, which is destroyed during the fight.

To even the playing field, Red Skull brings together the Cabal, consisting of Attuma, Dracula, the Super-Adaptoid, and Hyperion (He also offers Doctor Doom a spot, but he turns down the offer). The Avengers and S.H.I.E.L.D. intercept Red Skull's transmission, learn of the Cabal's existence, and decide to remain together to battle them.

Season 2 The Avengers encounter Red Skull's master, Thanos, who is searching for the Infinity Stones. They collect all five Stones and defeat Thanos, but Ultron absorbs the Stones' power. After the Avengers ultimately defeat Ultron, Ant-Man becomes a new member of the team. Around the end of season two, Thanos manages to escape from a galactic prison that was meant to contain him with aid of the Black Order. Thanos then makes one final attempt to defeat the Avengers. With help from the people of Earth, the Avengers are able to defeat Thanos and the Black Order. In the aftermath, Captain America and Iron Man plan to make Earth an "Avengers World" by recruiting other heroes.

There is also a subplot detailing the arrival of the Squadron Supreme, Hyperion's old team which also consists of Nighthawk, Power Princess, Doctor Spectrum, and Speed Demon. Believed to have died when their home planet was destroyed, they come to Earth in an attempt to conquer it. After going into hiding, the Avengers manage to defeat the Squadron Supreme by waiting until the Squadron's members divide rule of the planet's continents, then they pull a surprise attack and trap each member of the Squadron Supreme. The Squadron Supreme is imprisoned in a special section of the Vault.

Season 3: Ultron Revolution The Avengers are forced to cancel their expansion plans and Ant-Man leaves the team due to a lack of global threats. After dealing with A.I.M.'s Scientist Supreme, the Avengers are shocked when Ultron returns and absorbs A.I.M.'s Super-Adaptoid technology. Now Ultron is seeking revenge on the Avengers for foiling his plans with the Infinity Stones' power, while continuing his plot to replace humanity with robots. During Ultron's battle with the Avengers, Terrigen Mist is spread worldwide, activating the superpowers of humans with latent Inhuman genes.

One subplot details Helmut Zemo, son of Captain America's old nemesis Heinrich Zemo, finding a working vial of the Super-Soldier Serum and using it on himself to gain the youth and strength to face the Avengers and avenge his father's death. Zemo recruits the Masters of Evil (which consists of Beetle, Goliath, Screaming Mimi, Fixer, and Moonstone), who masquerade as the Thunderbolts to undermine the Avengers. However, after being saved by Captain America, Songbird eventually convinces the team to reform and turn on Zemo.

When the President signs the New Powers Act, the Avengers are given Truman Marsh as their government liaison, who replaces Hulk with Red Hulk. Marsh is later revealed to be a disguise of Ultron, who mind-controls the Inhumans to attack the Avengers and possesses Iron Man. The Avengers are unable to free Iron Man from Ultron and instead place him in a dimension where technology does not work until they can find a way to drive Ultron out.

Season 4: Secret Wars The Avengers' plans to rescue Iron Man experience a major setback when a new version of the Cabal (consisting of Leader, Arnim Zola, Enchantress, Executioner, and Kang the Conqueror) transports them across time and space. Ant-Man, Captain Marvel, Ms. Marvel, Vision, and Wasp work with Jane Foster to rescue them.

It is later revealed that Loki had told a powerful being known as the Beyonder of Earth. He uses the Bifröst to retrieve locations from across the universe and fuse them into the planet Battleworld. With Iron Man back with the team, the Avengers form an unlikely alliance with Loki to rebuild the Bifröst and work with Jane Foster to defeat him after he betrays the group.

Season 5: Black Panther's Quest Following Loki's defeat, the Avengers invite Shuri to a party at their tower. However, after an attack by Atlanteans, Black Panther and Shuri set out to stop the Shadow Council, including N'Jadaka, Tiger Shark, M'Baku, and Zanda. T'Challa tries to keep this mission a secret, telling none of the Avengers except Captain America.

The Council seeks an artifact called the Crown, which can access the memories of the deceased. Baron Zemo tries to take the Crown for himself, but it becomes unstable due to being away from Wakanda. Captain America sacrifices himself to absorb the resulting blast, with Black Widow accusing Black Panther of killing him. With the Avengers and the world against him, T'Challa frees Klaw from incarceration to learn of Killmonger's plan. He, Shuri, and Klaw enter the Hall of Royals, a burial ground for Wakanda's deceased royalty, where T'Challa researches the Council's plans. He frees Captain America, who was absorbed into the Crown.

Council member Madame Masque attacks Atlantis, triggering a war between it and Wakanda. However, Bask, the sister of Wakanda's founder Bashenga, sacrifices herself to destroy Masque's laser. She leaves for the afterlife, naming Shuri her successor, while the Crown is destroyed.
