In some fun news for Supergirl fans, Mr. Mxyzptlk is returning to the Melissa Benoist-headlined series.

Via Deadline, Reno 911!’s Thomas Lennon is  set to play a tweaked version of a character who has already appeared in two episodes of Supergirl.

If you remember, Peter Gadiot played the mischievous rogue in Mxyzptlk’s previous appearances. The last time we saw the villain, the Girl of Steel convinced him to spell his name backwards – thus sending him back to his home dimension.

How will Supergirl get round Mr. Mxyzptlk having a vastly different appearance? Why, the show will simply remind audiences that this villain is a shapeshifter.

This won’t actually be Thomas Lennon’s first venture into the world of capes ‘n’ tights. In the relatively recent animated adventures for Adam West’s Batman and Burt Ward’s Robin, Lennon lent his vocals to the role of Chief O’Hara. Likewise, he actually had a small role to play in The Dark Knight Rises, where he appeared as Bruce Wayne’s doctor.
