In a new promo for the upcoming crossover between "Arrow," "The Flash," "DC's Legends of Tomorrow" and "Supergirl," the Dominators rear their ugly heads. The video reveals a few glimpses of the "Arrow"-verse's latest threat: yellow, mind-controlling aliens with needle-like teeth and large red spots on their foreheads.
In the comics, the Dominators are a race of super scientists ruled by a caste system. DC Comics' "Invasion!" saw them form an alliance with other powerful alien species like the Daxamites and Thanagarians in order to stomp out the metahuman threat before it could reach the stars, even as they tried to harvest the metahuman gene for themselves. Despite their advanced technology, however, they were never shown to have mind-controlling capabilities — unlike their upcoming television counterparts.
Starring Melissa Benoist as the Girl of Steel, “Supergirl” airs Mondays at 8 pm ET/PT on The CW. The network is also home to Grant Gustin as the Scarlet Speedster in “The Flash,” airing Tuesdays at 8 pm ET/PT, Stephen Amell as the Emerald Archer in “Arrow,” airing Wednesdays at 8 pm ET/PT and Arthur Darvill, Brandon Routh and Caity Lotz in “DC’s Legends of Tomorrow,” airing Thursdays at 8 pm ET/PT.
