On the parallel-universe universe of Earth-One, a scientist on the planet Aoran dedicated himself to cheating death by drawing power from the stars themselves. He invented the Starband, which made him immortal, but twisted his mind toward evil and prematurely aged his fellow Aorans. The people of Aoran wanted him to destroy the Starband, but having tasted immortality he refused to give it up. The ensuing battle left all of Aoran lifeless except for the scientist, now known as Evil Star. Evil Star sought new worlds to conquer and came into frequent conflict with the Guardians of the Universe and the Green Lanterns, including Hal Jordan.
The Guardians later sent Evil Star to the Erral Rehab Facility, where they used a brain wave nullifier in an attempt to cure him. This rehabilitation was only partially successful, as the nullifier stimulated his subconscious, recreating the Starlings, who brought him the Star Brand. Evil Star fled to Earth in a confused state, believing the Starlings were persecuting him. He fought with Ferrin Colos, one of the Darkstars, who flooded Star's mind with reminders of the lives he had taken, starting with his homeworld. Evil Star's mind shut down, and he was returned to the Guardians for re-education.
During 'Underworld Unleashed' Evil Star was freed by Neron, with enhanced Starlings, but returned to captivity by the Darkstars and Guy Gardner.
Starband: The Starband draws the energy of the stars. With the starband, Evil Star can:
- prolong Evil Star's lifespan
- enable him to fly
- survive in space
- create force blasts
- creates hard light constructs
If Evil Star is kept away from starlight for a prolonged period, his powers fade away. Since starlight is the same as sunlight, the Starband's force blasts and constructs serve to increase Superman's powers.
He is often aided by Starlings. Starlings are miniature duplicates of Evil Star that are super-strong and indestructible, but are virtually mindless without Evil Star to direct them.
- Evil Star and his Starlings first appeared on the cover of Green Lantern, Vol. 2 #37 (June 1965).
- He was created by Gardner Fox and Gil Kane.
