Along with Dark Claw, Hyena is the result of a government program to enhance mutants to serve in the military with the ultimate goal of creating the ultimate mutant weapon.  While Dark Claw opts to abandon the project and use his new adamantium claws and enhanced mutant senses to protect Gotham City, the Hyena escaped only to turn into a a criminal terrorist, attacking (probably subsidized by private interests) strategic targets all through the world. 

And one of his primary targets was attacking AIR FORCE ONE and taking down the president of the United States.  If it was not for the prompt intervention of Dark Claw and his sidekick, the Sparrow, Hyena would have succeeded.  Instead, Dark Claw manages to kick Hyena out of the president’s airplane, and jumps after him.  Unfortunately, while Dark Claw is hanging for his life by clinging to one of Air Force One’s landing tires, Hyena was prepared by wearing a parachute and is able to escape. 

No other adventures on this universe have been recorded.
