However, in The New 52 continuity, Sardath first appeared in Justice League United #2 by Jeff Lemire and Mike McKone.
Sardath is the lead scientist on the technologically advanced planet Rann in the Alpha Centauri system.
It was originally created as a communication device so he could contact other worlds; due to the amount of energy used, it became a teleporter.
The first planet reached was Earth, where it struck one of the world's native archaeologists, Adam Strange, and transported him across the galaxy to Rann.
[1][2] Despite his shock, Strange remained with Sardath and his daughter to protect the planet from extraterrestrial threats using Rann's technology.
