Some Mr. Mxyzptlk-related spoilers are below for the latest episode of Supergirl.
Supergirl has done a pretty stellar job with how it has handled a majority of the comic book superheroes and arch villains it has brought to live-action, and tonight delivered viewers' first peek at the classic Superman baddie Mr. Mxyzptlk. And not just the once during the episode's end, but also in the post-ep preview for next week's bonkers-looking installment, titled "Mr. & Mrs. Mxyzptlk." We'll talk about his brief "Luthors" appearance below, but we have to first break out this beauty of a moment in which the magical baddie poses as a Kryptonian hero.
Actor Peter Gadiot, known in recent years for roles on Once Upon a Time, Matador, and Queen of the South, is guest-starring as Supergirl's Mr. Mxyzptlk, and fan expectations are grand for his debut in The CW's Arrow-verse. He's making an immediate impact, too, with his very first moments throwing a wrench into Kara's life, and when he shows up in full next week, part of his mischievous mayhem will involve impersonating Superman, with the M-appropriate M-insignia on his chest. I love that so much, as I was indeed just as fooled as Supergirl was when his caped form landed in the shot. I'm just like a superhero in at least that one respect, which is something to tell the grandkids.
The episode title "Mr. & Mrs. Mxyzptlk" implies that the other-dimensional imp will find romance, and that approach was made known upon his arrival in the closing moments of "Luthors." As Kara was in the process of revealing her feelings to Mon-El, which surely had the characters' shippers foaming at the mouth, Double M inexplicably showed up and interrupted this most smooch-tastic exchange by declaring his own love for Supergirl. A tad more soap opera in nature than what comic fans may have foresaw in Mr. Mxyzptlk's big debut, but it looks like things will get even more out of hand as his trickery-fueled path to matrimony plays out.
Check out the trailer below, which also features Kara looking lovely in a wedding dress, as well as Mr. Mxyzptlk taking a monster of an uppercut to the jaw.
First appearing in Superman comics in 1944, Mr. Mxyzptlk isn't so much into destroying the human race or killing all the other aliens or blowing everything up, though he'd gladly fool Superman/Supergirl into believing he was going to do those things, just to make everyone freak out. While the old standard for defeating Mr. Mxyzptlk used to be saying his name backwards, the character has since expanded the mechanics that lead to his dimensional exile, so I can't wait to see how Supergirl showrunners Andrew Kreisberg and Ali Adler handle it.
