The cosmic buttinsky known as The Interferer has broken out of the back issue of The Omega Men that he had been trapped in for decades, thanks to the Flash's mommy issues or something. Shortly before the Post-Crisis DC Universe collapsed into Flashpoint, the Interferer read the Salvation Run trade paperback, and thought it was too cool. The Interferer tried to find Salvation, but failing that, landed in a back issue of Showcase with a joint similar enough to have some fun. Figuring nobody would miss them, the Interferer took all of the Martian Manhunter's rogues gallery to a battle planet inspired by Manhunter 2070. It would have been rad to kill J'Onn J'Onzz again, but he ended up in The Outsider, so we'll have to make do...
Ma'alefa'ak was absolutely ruthless, attacking from all directions. His body shapeshifted into blades and blunts. His eyes burned with Laser Vision. Parts turned immaterial, then solidified, rending muscle and cracking bone. The Martian Manhunter would have never fought in this manner, without hesitation, even relishing the violence inflicted. Still, "Malefic" lacked the full range of J'Onzz's powers, which have never proven a match to the Kalanorian since his rebirth in the Flame of Py'tar.
The Devil Men of Pluto had a fine run. They always do. They're unrepentantly evil, uncompromising even when individual members are threatened, and unwaveringly intent on their goal. Of course, so was their opposition, who had ravaged his own home world purely for personal gain. The Martian overpowered and outclassed them completely, beating and robbing them in barely any time at all.
Commander Blanx had the teleportation sphere and a devious plan. He transported himself and one other back to the Iron City... at least, in part. Despero's genetic make-up had been programmed into the sphere, but in his original form from earlier in his career. The Kalanorian was still a force to be reckoned with, and the Martian had even more limitations on his powers than the fallen brother of their mutual nemesis, J'onn J'onzz. Who will be the ultimate victor?
