Through the series, it was clear that Vicious could take over Liz's form and shape it into her own at any time, but mainly in times of high stress or threat to Liz's life.

The idea of the series originally was formed from the seed of a drawing of Liz Vicious as a Supergirl-like heroine which turned into a conversation about what kind of superhero she might be.
The series had two main characters, Liz, being human, and Vicious, being a Succubus-like demoness.

The series had two main characters, Liz, being human, and Vicious, being a Succubus-like demoness. While there were some sexual and violent themes, the core of the series was similar to that of a superhero origin story. When her life takes what seems to be a turn for the worst, she finds the companionship of Vicious, a powerful succubus who seems to need Liz as much as Liz needs her. The transformation seems to be a submission of Liz's personality and form to Vicious. It was shown that Vicious had the ability to use the bindings she wore to ensnare others or use them in battle to help defend herself.
