'Supergirl' Announces 'Mr. and Mrs. Mxyzptlk' in New Trailer
It just wouldn’t be Mister Mxyzptlk without a trick up his sleeve, and the impish 5th-dimensional trickster couldn’t even wait for his own Supergirl episode to debut. The classic Superman villain put in a first appearance with “Luthors,” and now gets his own trailer with a first look at “Mr. & Mrs. Mxyzptlk.”
