Instead of placing Maru back in prison, Wonder Woman sentenced her to Transformation Island, the Amazon penal colony where many female criminals were sent to reform. Although the majority of inmates have reformed with loving submission, Maru and seven other women refused to change their ways. The Saturnian slaver Eviless banded these rebellious super-villains together under the name Villainy Inc. Maru returned to her Doctor Poison disguise and tricked Queen Hippolyta into believing men had invaded Paradise Island. The villains were able to capture Hippolyta's girdle, which they used to defeat Wonder Woman. Doctor Poison then joined Eviless, Blue Snowman, and Cheetah on a boat with the captive Wonder Woman, plotting to imprison the Amazon on Transformation Island for revenge. Wonder Woman attempted to escape by turning over the boat, but the four members of Villainy Inc. defeated her once again. After traveling to Transformation Island, Eviless tortured Wonder Woman until the reformed criminal Irene led a mutiny against Villainy Inc. In the ensuing chaos, Wonder Woman and Hippolyta broke free of their chains and managed to defeat Doctor Poison and her three companions.
