Mxyzptlk, aka “Mxy,” is the impish, reality-bending trickster from the 5th Dimension, who previously visited National City to woo Kara Danvers, aka Supergirl, but created chaos in the process. British actor Peter Gadiot portrayed Mxyzptlk for that two-part Season 2 adventure, but the transition to Lennon is smoothed by the character’s handy reputation as a shape-shifter with an unpredictable nature.
And Lennon has some comedy chops.
Lennon played Felix Unger opposite Matthew Perry’s Oscar Madison in CBS’ 2015-17 revamp of The Odd Couple and starred on the MYV comedy series The State. He and his writing partner, Robert Ben Garant, created the popular Viva Variety and Reno 911!, which aired for three and six seasons, respectively, on Comedy Central.
