Earth-51 is one of the many realities in the Multiverse.
When the Crisis erupted, this reality was destroyed when an anti-matter wave was unleashed upon it by the Anti-Monitor. After the Paragons rebooted the multiverse, Earth-51 was restored along with the other Earths of the multiverse.
- The mention of Thaddeus Brown as resident of this Earth is presumably a reference to Thaddeus Brown's creator Jack Kirby and the New 52's Earth 51 which is reality that is home to several Kirby's creations such as Kamandi or the New Gods.
