DC Entertainment and The CW have announced that the four-part CW superhero crossover of Supergirl, The Flash, Arrow, and DC’s Legends of Tomorrow will feature an all-new villain to menace their heroes in the form of The Dominators.
A sinister, technologically advanced alien race, The Dominators view Earth’s tendency to generate super-powered people as a sign that humans may essentially evolve to be genetically superior. That in mind, they decide to wipe them out.
The four-part CW superhero crossover will air this December with the Arrow episode being the 100th episode of the series and star Stephen Amell has been teasing the arrival of the other heroes (and a surprise villain) for the episode, which you can see below.
Supergirl airs Mondays at 8 PM on The CW followed by The Flash on Tuesdays, Arrow on Wednesdays, and DC’s Legends of Tomorrow on Thursdays.
