Saturnia

Origin
Saturnia and her accomplice, The Gloat, were criminals who fled to Earth when they were exiled from the planet Saturn. As soon as they arrived, they made plans to conquer the Earth, but they were foiled time and again by The Blue Beetle.

Saturnia and The Gloat both demonstrated the ability to take possession of other people's bodies, including the body of the hero, Blue Beetle. Saturnia later commanded an army of zombies. The Gloat demonstrated the ability to morph his body into anything he wished, including an octopus and a flaming sowrd. It is unclear if Saturnia also had this ability.
