Curt Connors

Dr. Curtis Connors was a biology teacher and ESU and scientist studying reptiles and cell regeneration. Connors had lost his arm as a surgeon in the Vietnam War. He became so desperate on regrowing his arm, that he tested his reptile potion on himself. The serum regrew his arm but also turned him into a Lizard creature.

He went through New York’s sewers like an animal. Peter Parker needed money so he had to try to take pictures of the strange Lizard creature and sell them to the Bugle. When the Lizard kidnapped Martha Connors, Spidey had to intervene to save her. He discovered that the Lizard was Doc Connors mutated. He used a gene-cleansing device to cure Connors and save Martha.

In his next appearance, he helped Spidey to identify his Alien Costume as a hostile symbiot. He appeared again in season two, helping Spidey get through a mutation disease. In Tablet of Time, Connors is studying a supposed fountain of youth called the Tablet of Time. This makes him the target of both Silvermaine (who wants to be young again) and Kingpin (who wants to sell it to the highest bidder). He transforms into the Lizard and goes crazy again but soon turns back to normal and is kidnapped by Tombstone for Silvermaine. At the end, he turns back into the Lizard and battles the younger Silvermaine who defeats the brute easily. Curt is cured again by being exposed to the Tablet’s rays.

He appears again to help Spidey in the Vulture two-parter when Vulture accidentally turns into Man-Spider after absorbing Spidey’s youth. Connors returns Spider-Man youth but leaves the disease in Vulture. When Vulture and Scorpion team up to destroy Spidey and Connors, he turns into the Lizard again but reverts to normal after his lab explodes.

In season three and most of season four, he functions as a scientist for Peter, helping him with scientific puzzles. Mutant lizards that lived in the sewers found out that Dr. Connors created them later abducted Connors. He became their Lizard King and ruled over them and the games they participated in. With help from Mary Jane, Debra Whitman, and Margaret Connors, Spider-Man was able to return Curt to his human self.

During the Secret Wars, the Beyonder kidnapped the Lizard to be a part of his team of villains. After he crashed into the heroes' headquarters, the Lizard was captured. Reed Richards was able to revive the human portion of his brain. The Lizard helped the team of heroes battle Dr. Doom and the other villains, as well as help Reed Richard and Iron Man operate the alien technology.
