Farris Knight comes from the 853rd Century and is a descendant of both Ted Knight and the Mist. Farris wields an alien device called a Quarvat, similar in function to the Cosmic Rod. He lives on a space station orbiting the planet Uranus, from which he monitors the artificial sun Solaris. He asserts that being the descendant of the Mist as much as the Knights he was predisposed to villainy and Solaris eventually corrupts Farris who arranges for the defeat of the two Justice Leagues and travels back in time to kill the originator of his hated responsibility, the original Starman Ted Knight. Meeting Ted however changes his mind and Farris ultimately sacrifices himself to save the modern day Earth from Solaris' machinations.
Farris reappears as being mind-controlled by Brainiac, along with rest of Justice Legion Alpha.
