While it doesn't seem like The CW is releasing any more new promos for the sixth and final season of Supergirl, they are still sharing new promotional stills, which are almost as revealing. This week's batch reveals the return of Thomas Lennon as Mr. Mxyzptlk.
The hour will once again see Kara (Melissa Benoist) and her Superfriends square off against Nyxly (Peta Sergeant), as they do everything they can to protect Mxy from her infinite rage. It also sounds like his reappearance will give us some much-needed backstory on this season's dangerous big bad.
Elsewhere, Lena (Katie McGrath) visits her mother's birthplace, seeking answers about her past, but is surprised to receive quite a negative reception from the locals.
Check out new stills from episode eleven, titled "Mxy in the Middle," below:
