Avengers: The Symbiote War

Avengers: The Symbiote War is a Direct-to-Video animated film series based on Marvel Comics and inspired by the events of the Marvel Cinematic Universe. It serves as a sequel to Avengers: Chronicles of the Infinity with elements of the 2018 Venom film. The film follows the Avengers (now officially joined by Kamala Khan as Ms. Marvel) and the Guardians of the Galaxy resuming their crime-fighting activities while they deal with the new threat of Symbiotes, which had been salvaged and experimented on by Dr. Carlton Drake and his crew from Life Foundation following Thanos' defeat. At the same time, Peter Parker and Kamala are entrusted by their mentors to look after journalist Eddie Brock, who was infected and bonded with a fugitive Symbiote which grants him superpowers as long as they share the same body.

Plot
Shortly after the Avengers' previous victory, a group of Damage Control salvagers working for Life Foundation explored and salvaged a series of items within one of Thanos' destroyed Q-Ships. From the ships, they had also encountered Symbiotes, liquid-like alien parasites which can possess and control host bodies of other organic lifeforms. Following orders from their director Dr. Carlton Drake, the Life Foundation scientists begun to perform unlawful experiments on citizens and prison convicts. Among those humans, journalist Eddie Brock, who was interviewing some scientists, was possessed by a Symbiote which had escaped the facility and, after a brief havoc, forcibly went in hiding.

In Present Day, the Avengers (consisting of Tony Stark / Iron Man, Steve Rogers / Captain America, Thor, Bruce Banner / Hulk, Carol Danvers / Captain Marvel, Natasha Romanoff / Black Widow and Clint Barton / Hawkeye) and the Guardians of the Galaxy (Peter Quill / Star-Lord, Gamora, Rocket, Mantis, Drax and Groot) raid a Hydra facility in Edinburgh commanded by Ophelia Sarkissian / Madame Hydra, who has been experimenting on inmates of New York's Central Prison (including Adrian Toomes) using new weapons made of Thanos' technology. After the Hydra agents are defeated, Sarkissian ends up possessed by a symbiote (which one of the Hydra agents stole from a Life Foundation sector) and battles the heroes, who (with help from Toomes) destroy the organism and apprehend Sarkissian and Toomes is pardoned his accusations, though Rogers, Quill and Gamora express a new concern of a new threat which comes by.

Three days later, Peter Parker and Kamala Khan participate a Homecoming party at Midtown High and meet new student Miles Morales and Toomes' daughter Liz (who had moved back to New York with her mother after her father was pardoned) until the school is attacked by Rieg Davan, a paranoid alien gladiator who had escaped the Sanctuary II and is obsessively bent to destroy anything about music on Earth. On their guises of Spider-Man and Ms. Marvel respectively, Parker and Kamala defeat Davan before the Avengers and the Guardians arrive to apprehend him and Parker senses something dangerous at the moment he spots a silent and timid Brock close by.

Stark, Danvers, Quill and Gamora search for and explore Thanos' now abandoned but still active ship the Sanctuary II and encounter Taneleer Tivan the Collector, who has been left stranded in the ship after Thanos' death. The group also find more footage of Tivan having sent the Terrigen Meteor with the Aether concealed in it (the activity which was responsible for Kamala's Inhuman transformation and her bond with Parker, which resulted in the destruction of the Infinity Gauntlet). To their displeasure, it is revealed that the Aether was not the only thing which was concealed in the meteor; they soon discover that a Symbiote (just like the one which bonded to Sarkissian) had also been concealed and accidentally sent to Earth. Assuming that Parker and Kamala are in grave danger, Stark and Danvers search for them.

Following their suspicions about Brock, Parker and Kamala follow him to a warehouse, where Brock pleads for theirs and the Avengers' assistance with his condition, but just as the young couple agree to help, the Symbiote suddenly takes control of Brock, transforming him into the monstrous "Venom" and forces him to fight back. Stark, Danvers and Quill arrive to help fight Venom and defeat him. Brock consequently gains some control over the Symbiote when his girlfriend Anne Weying arrives. Brock is held at the Avengers' custody so that Scott Lang and Banner can find the resources to help him gain control over the Symbiote.

Reluctantly deducing that the Soul Stone could be the answer, Gamora, Kamala and Danvers travel to Volmir, where Peggy Carter, keeper of the Soul Stone, informs them the stone can only be retrieved by sacrificing a mortal of a irredeemable soul. Kamala consequently elects the burglar who killed Parker's uncle and, after bringing him in, they sacrifice him by throwing him off the mountain to his death, earning the stone. Meanwhile, Parker encounters Morales and discovers that he was bitten by a prototype lab spider which was experimented on by Dr. Drake in Midtown High and given with his own spider powers. After training him, Parker guides Morales to the Avengers Facility, where Stark provides Morales his own Spider-Man suit.

Still bent to apprehend Brock, Drake demands to unleash the Symbiote-possessed subjects to find him and retrieve his Symbiote, ignoring the others' warnings that they are still not fully under control. One of the subjects, Cletus Kasady (who was possessed by a red-shaped offspring of the original Symbiote and dubbed himself "Carnage") subsequently escapes and begins to wreak havoc in the Life Foundation facility, releasing the other possessed convicts, who go for a rampage.

As the Avengers and the Guardians battle the Symbiote mutants, Parker and Morales manage to get the evidences of Drake's crimes, but not before Drake fuses himself with one of the Symbiotes, dubbing himself "Riot" and uncontrollably becomes part of the rampage. Fused with the Soul Stone, Brock gains full control of the Symbiote and uses it help the Avengers battle the Symbiotes. All possessed convicts are stripped off their Symbiotes thanks to a nano-tech antidote Lang and Banner developed using Vibranium particles provided by T'Challa.

Only Drake remains and he and Brock engage into a vicious fight in their respective symbiote forms. Brock distracts Drake long enough for Parker and Stark to blast them both with a antidote-laced bomb. Drake is stripped off his antidote and rendered unconscious, but Brock is nowhere to be found after the explosion.

In the aftermath of the battle, Life Foundation is discontinued and disbanded as Drake, exposed for his crimes by Parker, is arrested in Ravencroft Institute, where the inmates proceed to get their revenge on him. Weying mourns for Brock's apparent demise as she is comforted by Kamala and Danvers as Morales is welcomed to the Avengers as Kid Arachnid. Meanwhile, Brock (who had survived the explosion thanks to a Space Stone prototype he collected in the Avengers Facility) watches a sunrise on another planet, albeit unaware that the Symbiote is still alive in him.
