Biography
Frank is the name given to a sentient Venus fly trap plant. He was cultivated by Pamela Isley, aka Poison Ivy, and resided in her apartment complex in Gotham City. Frank had the ability to speak and was the closest thing that Pamela had to a friend until Harleen Quinzel came along. Frank was fairly self-sufficient, and was capable of fending for himself even during times that Isley was incarcerated at Arkham Asylum. One of Frank's chores during this time was to make sure that the rest of Isley's plants were properly watered.

Being a potted plant, Frank's actions were primarily rooted (parden the pun) to Ivey's apartment. However, he was also quite resourceful, and even found a way to drive a car to find Harley Quinn to help him out after learning that Ivey was in trouble.
