Damocles was a scientist from a parallel earth where their inhabitants abused of their natural resources, exhausted them and polluted the atmosphere and the sea, leaving a hald dead world with little time to live on.
Worried for the future of his world and his family, (his daugther and his wife), Damocles developed a system to renewal the life of his planet, by stealing from other paralel earths. Opposed to this plan was Sigma, who considered such plan an aberration. Despite the refusal of the ruling class, Damocles went to activate his machine, but Sigma came to stoped, followed by armed guards. Sigma tried to reason with Damocles about the morality of his actions but Damocles don't listened and attacked Sigma. In the middle of the chaos, the machine started to operate, stolen the life of countless paralel worlds. But instead to give it to Damocles' world, all the energy went to Damocles, meanwhile Sigma dissapeared in the myriad of worlds of the multiverse, leaving Damocles alone. Damocles then discovered than the little life of his world was also taken, and everything on it was dead, but him. Crazed for the death of his loved ones, and full of powers derived of the energy of infinity worlds, Damocles went on a multiversal rampage, destroying earth after earth, searching for Sigma, whom blames for the destruction of his world.
During his travels, Damocles recruited the Sword and the Bounty Hunters ( who helped him to travel among the worlds, by pushing the moon against the earth, thus generating the energy enough to jump from one earth to another one). The circunstances of this alliance was formed are unknown.
Fire from Heaven
In the Fire from Heaven storyline, Damocles found the reborned Sigma on the main Wildstorm earth. The earth heroes opposed to Damocles, only to discover than he was a paralel version of Dr. Tsung, Sigma's advisor and gene-factor discoverer. In a last chance to defeat Damocles, Deathblow pushed him against the energy wall of the machine than was pushing the moon against the earth. The wall was a door to other dimensions and Damocles was lost, dispersed among the multiverse.
In the New Dynamix mini was hinted than a post Worldstorm version of Damocles could appear. This plot was left unresolved.
