Gadiot was previously said to have a two-part stint as the character, though that may have included the initial appearance.
In any case, catch the trailer below, and stay tuned for more Supergirl.
The character made his first official appearance in the closing minutes this past week’s “Luthors,” interrupting Mon-El and Kara’s first and Maggie (Floriana Lima) celebrate their first Valentine’s Day together.
Now, Gadiot previews Monday’s “Mr. and Mrs. Mxyptlk,” as well addressing the change in appearance.
