In the Comics, Earth-17 is one of fifty-one divergent realities that branched from the core New Earth reality during the recreation of the Multiverse shortly following the events of Infinite Crisis. Somewhere in this Earth's past, there was a disaster-referred to by the inhabitants as the Great Disaster. Some say it involved atomic weapons, others say the mysterious chemical called Cortexin was involved somehow. Little is known about this Earth, except that it is described as "glowing with radioactivity and hope". It is home to intelligent animals and human slaves who have mostly lost the power of speech. However, the planet survives, and people there are hard at work to put the planet on an equal footing with its parallel counterparts.
