'The Lizard', aka 'Dr. Curt Connors', debuted in Marvel's "The Amazing Spider-Man" #6 (November 1963), created by writer Stan Lee and illustrator Steve Ditko.
Born in Coral Gables, Florida, Connors was a doctor who enlisted in the army, then sent off to war to perform emergency battlefield surgery on wounded GIs. But Connors right arm was injured in a blast and had to be amputated.
Returning to civilian life as a research technologist, Connors became obsessed with uncovering the secrets of reptilian limb regeneration. From his home in the Florida Everglades and with the assistance of war buddy 'Ted Sallis', Connors developed an experimental serum extracted from reptilian DNA.
After successfully regrowing the missing limb of a rabbit, Connors ingested the formula himself. His missing arm grew back, but he also transformed into a reptilian humanoid monster.
As the 'Lizard', Connors' strength increased to superhuman levels, with his speed, stamina, agility and reflexes raised to a level equivalent to that of 'Spider-Man'.
The Lizard can also scale walls using a combination of claws and micro-scales on his hands and feet that create molecular friction. He is highly resistant to injury due to his scaly hide, with enhanced healing abilities, allowing him to quickly recover from grievous wounds, including regenerating lost limbs. He also has a powerful tail which he can whip at high speeds and razor-sharp teeth set in muscular jaws that can deal a lethal bite.
Like all reptiles, the Lizard possesses cold-blooded characteristics, acutely sensitive to drops in temperature, causing his metabolism to slow down and become dormant if exposed to frigid temperatures.
The Lizard can also mentally communicate and command all reptiles within a mile of himself via telepathy, also compelling humans to act out their primal urges, by suppressing emotional control in their 'amygdala', aka 'the lizard brain'.
