Anti-Venom appear in Ultimate Spider-Man. Venom and Anti-Venom are created by Doctor Octopus for Oscorp, who made the former from an altered sample of Spider-Man's DNA and the latter from a sample of Venom as a countermeasure. In the series, Harry Osborn is depicted as the symbiote's host and initially uses it to become a black-suited Spider-Man, until his continued usage of it turns him into Venom. The Carnage symbiote is initially created by the Green Goblin after bonding the Venom symbiote to Peter Parker, before it was recreated by HYDRA scientist Michael Morbius from a sample of the Venom symbiote he obtained. Anti-Venom is also created from a sample of the Venom symbiote and bonds with Harry. A variant of the Venom symbiote appears in the Hulk and the Agents of S.M.A.S.H. episode "The Venom Within". Doctor Octopus creates a "Gamma Venom" variant of the symbiote by having the regular symbiote bond with the show's titular characters before it is destroyed by the agents of S.M.A.S.H., with Spider-Man's help. The Klyntar appear in Guardians of the Galaxy. Though the titular characters first encountered them in the episode "Hitchin' a Ride", it is not until the three-part episode "Symbiote War", when they learn that Klyntar's original homeworld was destroyed by Thanos, who captured most of them and took them to Planet X so he could weaponize them by altering their genealogy. The Exolons are also referenced as inhabiting Wraith's body. Carnage and Venom both appear in the episodes "Back in the New York Groove" and "Drive My Carnage". In this series, Carnage is an original Klyntar and not an offspring of Venom. The Klyntar appear in the 2017 Spider-Man series. Venom, initially referred to as the "V-252", arrives on Earth inside a meteor and is recovered by the Space Program, who leave it at Horizon High so Max Modell can analyze it. It first appeared in the episode "A Day in the Life", and bonded with Spider-Man in the episode "Sandman". In the episode "Stark Expo", Spider-Man rejects and returns it. In the episode "Venom", the V-252 briefly escaped and possessed Flash Thompson until Spider-Man defeated it and returned it once more. In the episode "Dead Man's Party", the V-252 merged with Eddie Brock, who renamed it Venom. In the episode "Venom Returns", Venom was incapacitated by an experimental sonic device during a failed attempt to publicly expose Spider-Man's secret
