This week we’re honoring one of my favorite Batman villains, Dr. Pamela Lillian Isley. She first appeared in Batman comics in 1966 as a notorious eco-terrorist. Robert Kanigher created Poison Ivy, and modeled her after Bettie Page. At her debut, Poison Ivy didn’t have a strong (well, any) origin story. However, over the years she was developed into a complexly developed character. In fact, she just made many fans happy (or irate, depending on who you ask) by confirming rumors that she is in a romantic relationship with her long time BFF Harley Quinn.

For the square I chose her signature leaf covered mask and the chemical symbol for Urushiol, the compound that makes up the “poison” in a poison ivy plant. I think Dr. Isley would appreciate that the bulk of the square space went to science.
