What will bring the Green Arrow, The Flash, Supergirl, and the Legends of Tomorrow together?

WB has announced that the big bad for this season’s four-way crossover between Arrow, The Flash, Supergirl, and DC’s Legends of Tomorrow will be DC Comics’ Dominators.

“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,” Arrow and Legends of Tomorrow EP Marc Guggenheim says. “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.”

In the comics, specifically in Invasion!, the Dominators are a technologically advanced alien race who form a coalition with various other races to invade Earth all in the name of eliminating the threat posed by unpredictable metahumans. To note, the Daxamites were part of the coalition, and the newly arrived Mon-El (Chris Wood) on Supergirl hails from Daxam. Coincidence?
