Princess Power fought crime with the Freedom Brigade until retiring twenty years ago. She married Theo O'Day and became the stepmother of Angel O'Day. She mothered a daughter, Athena Tremor, who was forced to become a hero with the Inferior Five. Princess Power became a teacher at Dean Egghead's Academy for Super-Heroes.
Years later, when her daughter Athena goes to visit Angel, she mentions that Princess Power passed away sometime before June 1983.
- Although this character was originally introduced as an inhabitant of DC's Pre-Crisis Earth-Twelve reality, their existence following the events of the 1985–86 limited series Crisis on Infinite Earths remains intact. However, some elements of the character's Pre-Crisis history may have been altered or removed for Post-Crisis New Earth continuity, and should be considered apocryphal.
- Pre-Crisis, Dumb Bunny's father was mentioned as being Steve Tremor. In Angel and the Ape (Volume 2), that marriage was changed to one with Theo O'Day.
