Patrick Mulligan

Patrick Mulligan is a New York City police officer who becomes bonded to Toxin, the symbiote offspring of Carnage, making him the host of the most powerful symbiote ever spawned — and an unexpected figure caught between the worlds of hero and monster.

Patrick Mulligan burst onto the Marvel scene in 2004's Venom vs. Carnage, the creation of writer Peter Milligan and artist Clayton Crain, dropping him straight into one of the most dangerous corners of the symbiote universe. His Modern Age debut places him amid heavy hitters — Spider-Man, Venom, and Carnage all share his pages — and his story has threaded through landmark collections like King in Black, suggesting a figure whose significance outlasts a simple cameo. With two decades of publication history behind him, Mulligan is a compelling piece of Marvel's symbiote mythology, the kind of character that rewards readers who dig deeper into the darker, more visceral side of the Marvel universe.
