Cara Buono (Stranger Things) and Mitch Pileggi (X-Files) are set to recur in season five of Supergirl.
Buono will recur as Gamemnae, an ancient alien, who with others of her kind, have been safeguarding the Earth from the follies of humanity throughout the ages. Gamemnae’s aim is to use technology to subjugate humans. Gamemnae is cunning, witty, ruthless, and always ten steps ahead of her adversaries. Gamemnae’s agenda puts her into conflict with her would-be allies and on a collision course with Supergirl.
Pileggi will recur as Rama Khan, an ancient alien who is able to control the four ancient elements — fire, water, earth, and air. Arrogant and willful, Rama Khan has been entrusted to use his powers to protect the Earth from mankind for millions of years but now his agenda puts him at odds with Supergirl as well as Lena Luthor.
The two characters were introduced in 2002 in the DC Comics series called JLA, an acronym for the Justice League of America. In the comics their ancient magic and grand schemes are tied to Atlantis, the fabled city that exists beneath the waves of the ocean.
Supergirl season five premieres on October 6th, 2019.
