Supergirl: First Look at White Martians

Last night following CBS's Supergirl, a trailer played for next week's episode -- revealing the first look at White Martians, as they appear on next week's episode "Strange Visitor From Another Planet."

As far as we know, there's only one white Martian so far -- although in their most memorable comics appearances they generally appear in groups as part of an organized invasion force.

Kara must help Hank face his painful past when a White Martian, a member of the alien race that wiped out his people, kidnaps Senator Miranda Crane (Tawny Cypress), an anti-alien politician. Also, Cat's estranged son, Adam (Blake Jenner), arrives in National City.
