20She got her powers through toxic injections
Although Pamela Isley was created in 1966, she wasn’t given a proper origin until 1978. The story contradicted earlier accounts of her real name, instead revealing her to have been born Lillian Rose.
She was a botanist who was poisoned by Marc LeGrande after she helped him steal an ancient artifact
- he was afraid that she would implicate him in the crime. However, Crisis on Infinite Earths completely rewrote DC’s history and Ivy was one of many whose origins were updated.
Dr. Pamela Lillian Isley studied botanical biochemistry under Dr. Jason Woodrue, aka the Floronic Man. Enthralled by her professor, Pamela was both romanced and experimented on. She nearly lost her life, but survived. Her fragile psyche wasn’t so luck,y though, and the toxins left her mentally unstable.
