the secrets of reptilian limb regeneration. Working from his home in the Florida Everglades with the help of war buddy Ted Sallis, he finally developed an experimental serum taken from reptilian DNA. The serum successfully regrew the missing limb of a rabbit, so then Connors chose to test the serum on himself. He ingested the formula and he did indeed grow a new arm. However, the formula had an unfortunate side effect: Connors was subsequently transformed into a reptilian humanoid monster. Spider-Man discovered this situation during a trip to Florida to investigate newspaper reports of the Lizard after his employer the Daily Bugle challenged him. After discovering the Lizard's true identity and origin, Spider-Man used Connors' notes to create an antidote to restore him to his human form and mentality. Another attempt to develop this serum for safe use again resulted in Connors transforming into the Lizard, but on this occasion he was saved thanks to his former colleague Professor X and his first team of X-Men, the Beast and the Angel tracking the Lizard down in the swamps so that the Iceman could send him into hibernation long enough to develop a cure. Life in New York Later, Curt Connors relocated to New York City. He was able to repay Spider-Man by developing a formula to save May Parker's life after Peter Parker had given his aunt his radioactive blood during a transfusion, unintentionally putting her in mortal peril. It later became clear that the success of Connors' apparent cure from the Lizard persona was short-lived. A repeating pattern soon occurred, with stress or a chemical reaction turning Connors into the Lizard, Spider-Man fighting him, and then forcing him to swallow the antidote to reverse the transformation until the next time. A second personality had formed with the Lizard, one with the familiar goal shared by many villains of taking over the world. The Lizard envisioned a world where all humans had been transformed into (or replaced by) super-reptiles like himself. Despite the Lizard's overall hatred of humans, he was often shown to be unwilling to harm his wife Martha or young son Billy. As Connors, he aided Spider-Man in defeating the Rhino by developing a formula to dissolve the Rhino's bulletproof hide, but accidentally transformed himself into the Lizard due to exposure to the chemicals needed to create the formula and was restored by Spider-Man. Connors was later
