Real Name: Inapplicable
Appearances: Secret Origins, Parts 1-3
Nothing is known about where these aliens originally came from before
their arrival on Mars. Upon their arrival, they took over the planet and eventually killed off all Martians, except for J'onn
J'onzz. J'onn managed to entrap the aliens and they became frozen from a special gas. They were released unintentionally when
an astronaut from Earth, J. Allen Carter, opened the prison.
The leader of these aliens is the Imperium. He commands and sends
out orders to the aliens to do his bidding.
After their release, they came to Earth, with hopes of taking it over.
Through the combined efforts of Superman, Batman, Wonder Woman, Green Lantern, Flash, Hawkgirl, and J'onn J'onzz, the Martian
Manhunter, the aliens were defeated and were vaporized from the sun's ultra-violent rays. The Imperium managed to escape from
the Justice League and went off into space.
