In a teaser trailer that aired tonight during Supergirl, The CW has revealed the first official look at The Dominators, the alien race that will invade Earth during the upcoming four-show crossover between Supergirl, The Flash, Arrow, and DC's Legends of Tomorrow.
You can see a couple of shots of them in the attached image gallery.
The Dominators, who first appeared in Legion of Super-Heroes comics, were the instigators of the Invasion! event in the comics, corralling an alliance of superheroes including Daxamites (one of whom, Mon-El, appears regularly on Supergirl this season) against Earth.
Arrow, The Flash, and Supergirl will cross over with DC's Legends of Tomorrow next month in "Invasion!" a three-part crossover that starts in the final moments of an episode of Supergirl and then plays through the other series. Based on the 1988 comic book event miniseries Invasion! from Keith Giffen, Bill Mantlo, Todd McFarlane, Bart Sears, and more, EW confirms that it will closely track the plot of that storyline: aliens will be assembled by The Dominators and descend on Earth to bring an end to the "threat" of Earth's burgeoning metahuman community.
In the TV version, rather than assembling a loose alliance of dangerous alien races, the Dominators will apparently be mind-controlling the aliens that join them. There's been some strong hinting that could mean heroes squaring off against other heroes as the mind control becomes part of the story.
"This year, for our mega 'Arrowverse' crossover, we’re taking inspiration from a DC crossover from the late 1980s known as Invasion!, which featured an alien race called the Dominators, who’d previously vexed the Legion of Superheroes," said Arrow and DC's Legends of Tomorrow executive producer Marc Guggenheim. "We’re using cutting edge prosthetics and computer effects to achieve a feature film-quality look which is faithful to Invasion! artist Todd McFarlane’s interpretation of the characters.”
Supergirl airs Mondays at 8 p.m. ET/PT; The Flash on Tuesdays at the same time; Arrow on Wednesdays and DC's Legends of Tomorrow on Thursdays. All four series air on The CW. The "Invasion!" crossover will air beginning November 28.
