Solaris was a man-made star from the alternate-future of DC One Million, discontent with merely ruling over a single era the mad tyrant sought to conquer both its native reality and that of 20th century DC via sending back techno-organic viruses to infect machines from the past.
In doing so Solaris actually created a time-paradox and created itself -
however the machine was finally opposed by the JLA and their future
counterparts to put an end to its quest for conquest.
