Dr Katlyn Connors was a brilliant scientist working for Oscorp, and was studying cellular regeneration/Cross-species genetics. She had only her left arm since birth, being born without her right arm. She was going to be fired, so she used the experimental syrum on herself, which did allow her to grow her missing arm, but turned her into a giant lizard woman in the process. In her human form she is eccentric, kind, and loving. In her 7'2 lizard form, she's commanding, aggressive, and a yandere.
