Cross-Species Genetics Research

One of Oscorp's leading scientific minds, Dr. Curtis Connors is an expert in biology and is happily married to Martha Connors. Connors also has a son, Billy. Dr. Connors lost his arm in a car accident, and ever since then, he dedicated himself to finding a means of restoring lost limbs through cross-species genetics.

Over a decade later, Connors continued the cross-species research, first by creating hybrid animals, including multi-species spider hybrids. He also wrote a book about the possible medical breakthroughs from cross-species genetics. During this time, he met Peter Parker who was on a field trip at Oscorp. Unbeknownst to Connors, Peter was bitten by one of the experimental spiders that escaped, gifting him extraordinary powers, and he became the crime fighter known as Spider-Man.

Connors was still working on the project at Oscorp, however, but without major breakthroughs, his sponsors were on the verge of cutting his funding. Under time constraints, Connors was unable to complete the project, but after allowing Peter to work on the project with him at Oscorp, Peter supplied a missing algorithm, leading to the successful development of a regeneration serum based on lizard DNA. His superior Norman Osborn decided to fast-track human testing, but Connors plead with him to wait until they knew all the side effects but Norman didn't take his suggestion lightly and threatened to fire him. Norman then took the serums and decided to test them at the city's largest veterans' hospital by the next day.

Becoming the Lizard

In the hopes of preventing this, Curt decided to test out his latest project on himself. Though agonizing, the serum worked, and Connors's missing limb regenerated. Ecstatic, Connors immediately told his findings to his superior, Norman Osborn, but failed to finish as he found out the serum was corrupting his genes.

Connors left the lab and orders a taxi driver to drive to the Veterans hospital in hopes of stopping Norman from injecting the serum into the patients. Not soon after, Connors fully transformed into the Lizard. As the Lizard, he can't talk, yet he was also acts purely on animalistic instincts. The Lizard is extremely aggressive, shown attacking with little or no provocation. Suffering from mental problems as a result of his transformation, the Lizard attempts to kill Norman Osborn on the bridge, but is stopped by Spider-Man. After he escapes, Connors seeks refuge in the sewers where he created a makeshift lab, he began to try to create a formula to cure himself of the Lizard without losing his arm. After testing the "cure" on himself, he transformed back into the Lizard once again, and attacked Oscorp. The Lizard attempted to kill Osborn but was saved by Spider-Man yet again. During the fight, Spider-Man tries to reason with him, but to no avail as the Lizard continues to attack him. After a lengthy battle, the police arrive, and The Lizard retreats.

The Lizard vs. Kraven the Hunter

Kraven the Hunter had received word of a giant lizard that was attacking New York, and he saw this as a great opportunity, thinking it would be a great worthwhile hunt. But of course, this idea didn't bode well with Spider-Man. Spider-Man plead with Kraven to stop, saying how the Lizard is actually a good man inside who had no control over his actions; and who could be cured of his condition. Kraven however would not listen, and Spider-Man ended up confronting Kraven. Kraven used many different potions and herbs to increase his strength and agility, but in the end, he was still no match for Spider-Man. The Lizard did came close to killing his wife Martha and his son Billy, but Spider-Man stopped him and restored him back to human form using the antidote developed by Eddie Brock. Curt was greatly thankful for Spider-Man's assistance in turning him back. Connors told Spider-Man that he'd help him with any problem he could.
