About
In this universe, there were no heroes, until a league of scientists known as the Justice Consortium created them. Technology had always been advanced on this Earth, but these new robotic creations were able to think and feel, and wielded powers beyond anything yet seen. They now defend the Earth from threats within and beyond, particularly the Doom Legion and their villainous assassin bots.
