Thomas Lennon Guest Stars as Mxyzptlk in ‘Supergirl’ 100th Episode (PHOTOS)
Mxyzptlk returns to Supergirl on February 23 for its milestone 100th episode — and he might be able to help Kara (Melissa Benoist) get her best friend back.
Previously portrayed by Peter Gadiot in Season 2, the trickster is now being played by Thomas Lennon. And this time, he has a proposition for Kara: What if she could go back in time and tell Lena (Katie McGrath) the truth before Lex (Jon Cryer) did? “It’s a Super Life” looks back over key moments throughout the series as Kara decides if she wants to change history in order to be friends with Lena again.
