Benn Blanx

Background Information
In the parallel universe, known as Earth-One, in February, 1959, a panic is generated by the revelation of the presence of Martians (specifically from J’onn J'onzz and his enemy Commander Blanx and his followers) on Earth. He is joined by the Flash, then a mere fledgling as a super-hero. The Flash, unable to cope with the situation alone, summons the more experienced Superman, Batman, and Robim and several other heroes. After their success, they decided to keep the alien invasion and the following skirmish a secret, hidden away from the public eye, by not releasing a public statement to the news outlets -– so as not to cause a panic.

(The now) General Blanx resurfaces again, leading an army to destroy the surface of Mars. His destruction forced the good Martians to leave and colonize another planet. The Manhunter tracks down Blanx in the ruins of Mars and the two battle one-on-one, and during the fight Martian Manhunter sends Blanx falling to his death. With his world destroyed, Manhunter decides to go with the survivors into deep space to find a new home and bids farewell to his friends in the Justice League.
