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 is the sequel to Avengers: Forces from the Infinity and the second installment of Iago PUC's Avengers Animated Trilogy with elements of the 2018 Sony Marvel Universe 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. The film is followed by a sequel entitled Avengers: Inhumans Unleashed.

Plot
One year before the Guardians of the Galaxy first banded together, Thanos had once invaded the planet Klyntar and experimented on Symbiotes, liquid-like alien parasites which can possess and control host bodies of other organic lifeforms, with the purpose to turn them into living weapons for his goal to eliminate half of the universe. However, when the organisms proved too wild and dangerous to control and one of Thanos' experiments with the Symbiotes turned one of them into the tyrannical Alpha known as "Riot", Thanos found no choice but to destroy Klyntar, though one of his lieutenants secretly took one of the planet's meteors containing Riot and four more Symbiotes.

Shortly after the Avengers' victory against Thanos, 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 the meteor containing the Symbiotes. Following orders from their director Dr. Carlton Drake, the Life Foundation scientists begun to perform unlawful experiments on homeless 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 the Avengers and the Guardians express a new concern of the great threat which the Symbiotes impose.

Three days later, Peter Parker participates a Halloween party after attending to a Stark Industries communitary internship by which he invited new students to attend to Midtown High (including his now-girlfriend Kamala Khan (who had moved from New Jersey to New York with her family), Aaron Davis' nephew Miles Morales and Toomes' daughter Liz (who had moved back to New York with her mother after hearing news that 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 and Nick Fury suggests Parker to keep Brock in check.

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. They 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 last 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 is surrounded by Drake's mercenaries led by prison convict Cletus Kasady (who is working for Drake in exchange of two years off his prison sentences) and Life Foundation's head of security Rolland Treece, but just before the young couple exact to help, the Symbiote suddenly takes control of Brock's mind and body, transforming him into the monstrous "Venom" and forces him to fight back against the mercenaries. Stark, Danvers, Quill, Gamora, T'Challa, Vision and Stephen Strange arrive to help fight Venom and defeat him. Brock consequently gains some control over the Symbiote when his fiancee Anne Weying arrives to see his mutation. 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, which cannot be separated from him and needs to feed so that Brock can be in control.

Reluctantly deducing that the Soul Stone is what they need to keep the Symbiote stable, Gamora, Maximoff, Strange, Vision and Rocket travel to Volmir, where Peggy Carter, keeper of the Soul Stone, informs them that the stone can only be retrieved by "sacrificing a guilty mortal with innocent souls to burn". Maximoff consequently elects Dennis Carradine (the burglar who killed Parker's uncle Ben) and, after bringing him in, Vision and Strange sacrifice him by throwing him off the cliff to his death, earning the stone. Meanwhile, Parker, Kamala and their friends gather on the Toomes' home and overhear more of Drake's schemes from the Avengers' agent Dora Skirth before Morales is bitten by a prototype lab spider which was experimented on by Treece (who is disguised as a teacher in Midtown High to track Brock) and given with his own spider powers. After teaching him how to control his powers, Parker guides Morales to the Avengers Facility, where Stark provides Morales his own Spider-Man suit and web-shooters.

Still bent to apprehend Brock, Drake demands the scientists 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. Kasady (who is possessed by a red-shaped offspring of the alpha Symbiote and dubs himself "Carnage") consequently defects from his captors 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 invasion force, Parker and Morales manage to get the evidences of Drake's crimes given to them by Skirth, but not before Drake fuses himself with Riot, who eventually takes control and leads the rampage.

Fused with the Soul Stone so that the Symbiote will not starve, Brock gains full control over Venom (who then agrees to help protect the Earth from its own kind) and the two help the Avengers and Guardians 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. However, only Drake remains bonded with Riot after draining the life forces of Kasady and Carnage, and he and Brock engage into a vicious fight in their respective Symbiote forms which takes place in a nearby rocket. Brock and Venom distract Drake and Riot long enough for Parker and Stark to activate the rocket, which takes off with both Venom and Riot in it. Brock and Venom steer the rocket towards an fiery comet and the two are apparently killed along with Riot and Drake when the rocket explodes.

In the aftermath of the battle, Life Foundation is discontinued and disbanded as the remaining scientists involved with Drake's schemes are arrested in the Raft, where the inmates proceed to get their revenge on Treece. Weying mourns for Brock's apparent demise as she is comforted by Kamala and Danvers and Morales is welcomed to the Avengers as Kid Arachnid while under Parker's supervision. Meanwhile, Brock (who had survived the explosion thanks to one of the Space Stone teleportation rings he collected in the Avengers Facility as) watches a sunrise on another planet with the Venom Symbiote, who is still alive in him.

Cultural References
Much like in the previous film and the original Marvel Cinematic Universe films, there are also several pop culture references and "Easter Eggs" (most of them being from Walt Disney productions and franchises).
 * After overhearing Gamora tell the heroes about the Symbiotes, Stark says: "And here I am thinking of those science-fiction and horror movies which Spidey used as a reference for the ideas he came up with... maybe that old one where aliens put eggs on humans' chests and eat them.", referencing the Alien franchise.
 * This moment also pays homage to the moment Parker and Stark defeat Ebony Maw to save Doctor Strange, on which the plan is based on the movie Aliens and Stark does so by blasting Maw off the ship.

 * Two jocks are wearing mascot costumes based on Shadow and Silver from the Sonic the Hedgehog series.
 * Kamala is shown wearing a costume based on Moana from the same name animated Walt Disney film; This is another homage to Auli'i Cravalho's performance as both characters.
 * Parker is shown wearing a costume based on a cybernetic armor which is based on the one worn by Kevin Flynn in .
 * At the moment he duels with Cletus Kasady / Carnage, Parker wields a series of weapons aside his Spider-Man suit. Those include a Sword-sized Key-shaped Vibranium stick. This is a reference and homage to Haley Joel Osment's performance as Sora in the Kingdom Hearts video game series.

Songs
Still like in the prequel, the film includes a small track of licensed songs which are heard in the background.
 * "" by The Edgar Winter Group: Played at the moment Aaron Davis uses a remote-controlled truck to help Spider-Man and Ms. Marvel defeat Rieg Davan. The song starts when Davan is hit by the truck, which is used as a bait for Davan to destroy it when he listens to the song, but only to be tricked into being blasted by the Chitauri grenades implanted inside it.
 * "" by Culture Club: Played on Taneleer Tivan the Collector's Walkman at the moment Tony Stark, Carol Danvers, Peter Quill and Gamora find him in the Sanctuary II.
 * "" by Rick Astley: Played at the moment Peter Quill and Miles Morales manage to defeat Cletus Kasady / Carnage by sticking two loudspeakers in Kasady's Symbiote body and playing the song, to which a berserk Rieg Davan (who is present in the same room Quill and Morales are) ends up believing Kasady was playing any songs with him and proceeds to viciously attack him. It is played again in the Post-Credit scene, when Carlton Drake's head of security Roland Treece accidentally plays a song in the cell's radio, causing Davan to beat him up (off-screen).

Sequel
The film is also followed by a sequel entitled Inhumans Unleashed. In the film, the Avengers and the Guardians of the Galaxy work to solve more secrets surrounding the origins of the Inhumans while they help the Royal Family of Attilan in saving their kingdom from a war started by the deceased Ronan's Kree successor Hala the Accuser, who longs to bring about universal order by obtaining an cosmic artifact which only the Inhumans can wield. On the middle of the chaos, Peter Parker and Kamala Khan make new friendships while they contend with the evil schemes of Victor Kohl / Exile, who seeks to undo the bonds between the Inhuman race and humanity, and Helmut Zemo, who has escaped prison and is allied with Exile and Hala for his own personal goals and his revenge on the Avengers.
