I've had a character with this name for more than 15 years, but I designed this version in 2007 as I was ramping up to start Ad Astra.
Electra is Trudy Malloy and her planet of origin is Nelvanna. She has the power to manipulate and generate electricity. She is a Nelvanna colonist on the colony world Alizon. Like most of the electro-types on Alizon, she fell under the thrall of Dagon, when he took over the planet.
