In Venom: Let There Be Carnage, yet another symbiote has been featured and teased by the film’s end, though it’s unclear if they’ll become friend or foe to Eddie Brock (Tom Hardy) in the future. While the sequel to 2018’s Venom sees the birth of Cletus Kasady’s Carnage (Woody Harrelson), the climactic battle between the serial killer and the Lethal Protector results in a new symbiote potentially being born known as Toxin, the symbiote son of Carnage and grandson of Venom, being one the most powerful symbiote characters in the pages of Marvel Comics.
In Let There Be Carnage, Venom accidentally birthed and left his offspring with Cletus Kassady during Eddie Brock’s final interview with the serial killer on death row. However, thanks to the inadvertent creation of his own symbiote that’s just as dark and sinister and Cletus himself, the pair becomes Carnage, breaking out of prison and wreaking havoc before breaking out Shriek (Naomie Harris), the love of Kasady’s life. By the film’s end, Carnage and Shriek decided to get married in a cathedral, bringing together guests they intended to kill: Venom, Eddie, and the officer that shot out Shriek’s eye years prior named Detective Mulligan (played by Stephen Graham). Mulligan was also the leading detective on Kasady’s case which saw him working with Brock (despite his deep dislike for the journalist).
That being said, Cletus offered a captured Mulligan to his betrothed as a wedding gift just before Venom interrupted their ceremony. While the ensuing battle saw Mulligan fighting with Shriek while Carnage and Venom battled, the detective was ultimately knocked unconscious. Even so, Venom still emerged as the victor and defeated both villains. However, the aftermath saw Mulligan’s waking up with his eyes glowing, seemingly confirming that he’s indeed Patrick Mulligan from Marvel Comics, the first host of Carnage’s offspring Toxin, a rare and powerful symbiote being the 1000th birth of Venom and Carnage’s shared lineage.
In the comics, Carnage sought to kill Toxin as soon as his offspring was born, finding the idea of a symbiote more powerful than himself unacceptable. However, Carnage was too weak after the birth in 2004’s Venom Vs. Carnage from Peter Milligan and Clayton Crain, allowing Toxin to bond with the nearby Officer Patrick Mulligan, its first host. In contrast, Venom was the one to give Toxin his name, hoping that he could become his ally against Carnage. Thanks to Mulligan’s career as a cop, the pair did indeed adopt a more heroic path, though Toxin’s youth and aggression saw Patrick often struggling to keep the unruly symbiote in line.
As a result, it certainly seems as though Stephen Graham’s Detective Mulligan becoming Toxin is being teased for a potential Venom 3, which would certainly be interesting given the tense relationship he and Eddie have already developed in this current sequel. That being said, given the major changes to Venom’s future when it comes to Marvel movies shown in the post-credits scene, it’s somewhat unclear if a future featuring Toxin is still in the cards.
Venom: Let There Be Carnage is now playing in theaters.
