The CW has revealed the main villains who will face off with DC's superheroes on the network's upcoming four-show crossover event, and the event is focusing heavily on characters that have been part of the DC-verse since the 1960s.

Arrow," "The Flash," "Supergirl," and "Legends of Tomorrow" will throw down with the Dominators, who were first introduced to comics fans back in 1967. Here's a breakdown of the quirky characters, per a report from Deadline:

"Dominators are members of the alien empire known as the Dominion, a rigid caste society in which social status is denoted by the size of a red circle on one's forehead. Emotionless and calculating, Dominators are masters of genetic manipulation who seek to enhance their abilities to aid in their conquests. ... Notable for tall, lanky frames, yellow skin and sharp teeth and nails, the aliens provide the strangest looking villains yet for [the] shared universe."

Marc Guggenheim, the executive producer of "Arrow" and "Legends," explained to TVLine that he's "taking inspiration from a DC crossover from the late 1980s known as 'Invasion!,'" and plans to address the villains' odd appearance through the use of some unique tricks.

"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," Guggenheim told the site.

Fans will get to see the Dominators in action later this season on The CW. "The Flash" premieres on October 4, "Arrow" premieres on October 5, "Supergirl" premieres on October 10, and "Legends of Tomorrow" premieres on October 13.
