Are you ready to return to Earth-X? Developed by Greg Berlanti and Marc Guggenheim, “Freedom Fighters: The Ray” premiered on December 8, 2017 on The CW’s online streaming platform, CW Seed.

For both the live action version of the character and the animated version, Ray Terrill / The Ray is played by Russell Tovey. Tovey made his Arrowverse debut as the character 28 Nov. 2017 in “The Flash: S4.E8 Crisis on Earth-X, Part 3“ and “DC’s Legends of Tomorrow: S3.E8 Crisis on Earth-X, Part 4.”

“Freedom Fighters: The Ray,” set in the Arrowverse, is part of the same fictional universe as “Arrow,” “The Flash,” “Vixen” and “DC’s Legends of Tomorrow.” Set on the alternate earth of Earth-X, the one we saw in “Crisis on Earth-X,” the animated series presents us with dark sinister versions of heroes we already know.

While Overgirl is the evil version of Earth-38’s Kara Danvers / Supergirl (Melissa Benoist), Black Arrow (Matthew Mercer) is that earth’s version of Earth-1’s Oliver Queen / Green Arrow (Stephen Amell). There are likely 51 other versions of these characters in the multiverse. We just have not met them all… yet.

Overgirl and Black Arrow, fighting on the side of Earth-X’s Nazis, a formidable foes for the series heroes The Ray, Red Tornado (Iddo Goldberg), John Trujillo / Black Condor (Jason Mitchell), and Jenny Knight / Phantom Lady (Dilshad Vadsaria).

Since certain characters are still alive in this animated series, we can assume it is set before events that transpired in the four-part Arrowverse crossover “Crisis on Earth-X.” It’s all rather complication but way too much fun to miss.

Not surprisingly, since the animated series is set on multiple Earths, there are multiple versions of Vibe / Cisco Ramon (Carlos Valdes). We even get to see an animated version of Caitlin Snow (Danielle Panabaker), Curtis Holt / Mr. Terrific (Echo Kellum) and Mari McCabe / Vixen (Megalyn Echikunwoke). It’s fun that the actors that play the live action versions of the Arrowverse characters also voice the animated versions.

In the third and fourth episodes of “Freedom Fighters: The Ray,” we learn what happened to Earth-X’s version of Terrill / The Ray and how the Earth-1 Terrill got The Ray’s superpowers. We also discover how the Earth-1 Terrill / The Ray gets to Earth-X.

Everything that transpires in the animated series corresponds with what took place during the Arrowverse crossover.
