Mr. Mxyzptlk’s (Peter Gadiot) arrival on Earth is going to strain Kara (Melissa Benoist) and Mon-El’s (Chris Wood) relationship.

According to the synopsis for Season 2, episode 13 of “Supergirl,” the Kryptonian and the Daxamite will argue over how to get rid of the magical imp, who shows up in National City and declares his love for the Girl of Steel.

Mon-El has encountered beings like Mr. Mxyzptlk on Daxam before, and while he knows how dangerous they can be, Kara thinks that the imp is harmless. Kara’s impression of Mr. Mxyzptlk, however, quickly changes when the imp decides to wreak havoc on the city after she tries to let him down easy.

In the comics, Mr. Mxyzptlk is from the 5th Dimension who loves to annoy Superman. Although not actually evil and doesn’t inflict any long-term damage to the Man of Steel, Mr. Mxyzptlk relentlessly pesters and proves that he’s smarter than the man of Steel. Mr. Mxyzptlk can only be made to return to the 5th Dimension when he’s tricked into saying his own name backwards.

Heroic Hollywood reported last month that Gadiot is set to guest star in two episodes of Season 2. So fans are going to see Mr. Mxyzptlk again after he makes his debut appearance in episode 13.

Gadiot isn’t the first actor to play Mr. Mxyzptlk on TV. In 1989, Michael J. Pollard played the character in two episodes of the syndicated series “Superboy.” Howie Mandel also portrayed the funny imp in the 1996 episode of “Lois & Clark: The New Adventures of Superman,” titled “Twas the Night Before Mxymas.” The character’s most recent live-action appearance was in the WB/CW series “Smallville,” in which he was portrayed by Trent Ford.

“Supergirl” Season 2, episode 13, titled “Mr. & Mrs. Mxyzptlk,” airs on Monday, Feb. 20 at 8 p.m. EST on The CW.
