Arrowverse Crossover Casts The Monitor, Hints Elseworlds Will Be a Crisis

The DCTV Universe might be headed for a Crisis. Today, The CW announced Designated Survivor star LaMonica Garrett has been cast as Mar Novu, "an extraterrestrial being of infinite power known as the Monitor," in the Arrowverse's upcoming Elseworlds crossover.

In the comics, the Monitor was essential to Crisis on Infinite Earths. Created by Marv Wolfman and George Perez in 1982's The New Teen Titans #21, the character was established to set up the events of Crisis. He is billions of years old, born as the living embodiment of the universe's positive matter; as such, he is the natural enemy of the Anti-Monitor, a being of anti-matter.

So, when the Anti-Monitor sent out an anti-matter wave with the intention to destroy the universe, the Monitor enlisted the help of heroes like Cyborg, Killer Frost, Firestar, Blue Beetle and Green Lantern. He planned to merge the multiverse into one single universe as a way to make them strong enough to withstand the anti-matter wave. He was killed by his Harbinger, who had been corrupted by the Anti-Monitor, but he was able to use his death to shield Earth-1 and Earth-2 from the attack; his posthumous actions also saved Earth-4, Earth-S and Earth-X. Ultimately, when the Anti-Monitor was defeated, the multiverse was "rebooted" as a single universe, the product of a combination between these five surviving universes.

In addition to Designated Survivor, Garrett -- who will play the Monitor across Supergirl, Arrow and The Flash -- has appeared in Sons of Anarchy and Black-ish. His past credits also include Transformers: Dark of the MoonNCISSuitsThe GameArrested Development and more.

DCTV returns to The CW this fall with The Flash leading the charge on Tuesday, Oct. 9 with its Season 5 premiere at 8 pm ET/PT, followed by Season 2 of Black Lightning at 9 pm. Supergirl will follow the next week on Sunday, Oct. 14 at 8 pm, with Arrow the next day on Monday, Oct. 15 at 8 pm. Finally, DC’s Legends of Tomorrow will return on Monday, Oct. 22 at 9 PM. The highly-anticipated crossover will air over three nights, starting on Sunday, Dec. 9 through Tuesday, Dec. 11.
