formulas for Connors to study. Fascinated by their potential in medicine, Connors injects himself with several doses of the lizard formula, which restores his right arm, but slowly mutates him into the Lizard, becoming more feral in the process. In response, Spider-Man reluctantly releases Doctor Octopus to help restore Connors to his human form. In "The Sinister Six", Doctor Octopus abducts Connors and forcibly turns him back into the Lizard before using a mind control device to have him join the eponymous group. While most of the Sinister Six are defeated by Spider-Man and his fellow S.H.I.E.L.D. trainees and arrested, the Lizard breaks free from Doc Ock's control and escapes. In "Stan By Me", the Lizard steals equipment from Midtown High School to render his human side dormant. Despite Spider-Man and retired S.H.I.E.L.D. agent turned janitor Stan's interference, the Lizard succeeds and escapes once more. In "Return of the Sinister Six", Spider-Man discovers an antidote that Connors created before the Lizard's consciousness took over and cures Connors. Following this, Connors makes minor appearances throughout seasons three and four, with his most notable appearance being in the episode "Lizards", wherein Connors is again transformed into the Lizard by Doctor Octopus's spy, Ben Reilly, and granted the ability to mutate others into anthropomorphic lizards via his bite. Spider-Man eventually creates an antidote for the Lizard and all those infected by him. The episode "Return to the Spider-Verse" Pt. 1 features a vampiric alternate reality version of the Lizard known as the Lizard King, who lives in and rules over a vampire-infested world. With Blood Spider as his only opposition, the Lizard King collaborates with Wolf Spider in a plot to obtain a Siege Perilous fragment to block out the sun so his vampires can rule the Earth. However, Spider-Man and Kid Arachnid combine Blood Spider's cured blood sample with the Siege Perilous piece and a UV Light to cure everyone, including the Lizard King. In the two-part series finale "Graduation Day", Doctor Octopus has Crossbones mind-controlled and mutated into a new Lizard to have him join the Superior Sinister Six, but Spider-Man is able to eventually cure and free him from Doc Ock's control. Dr. Curt Connors / Lizard appears in Spider-Man, voiced by Yuri Lowenthal. This version is an Oscorp scientist. Introduced in the episode "The Rise of Doc Ock Pt. 2", Osborn manipulates Connors into injecting himself with reptile DNA
