In the Valentine's Day-themed “Mr. & Mrs. Mxyzptlk," the magical scamp from another dimension is absolutely smitten with Melissa Benoist's Kara Danvers, and in this clip he seeks to woo her with candles, music and flowers. Never mind that Mon-El, played by Chris Wood, may have some objections.

"The other suitor," a somewhat-intrigued Mxyzptlk says in response to Mon-El's threat. "I didn't see you there, tall, dark and blandsome. You're barely there, let alone my romantic rival!" Unfortunately for Mon-El, the imp knows exactly how to deal with competition for Kara's affections.

DC COMICS’ MR. MXYZPTLK HITS NATIONAL CITY — When Mr. Mxyzptlk (guest star Peter Gadiot), a magical imp, shows up on Earth and declares his love for Kara (Melissa Benoist), she tries to let him down easy, thinking him harmless. However, he decides it’s a challenge and starts to wreak havoc on National City. Mon-El (Chris Wood) has seen beings like Mr. Mxyzptlk on Daxam and knows how dangerous they can be. He and Kara argue over how to get rid of Mr. Mxyzptlk, further straining their relationship. Meanwhile, Alex (Chyler Leigh) and Maggie (Floriana Lima) celebrate their first Valentine’s Day together.

“Mr. & Mrs. Mxyzptlk" airs Monday at 8 p.m. ET/PT on The CW. “Supergirl” stars Melissa Benoist as Supergirl, David Harewood as Martian Manhunter, Mehcad Brooks as Jimmy Olsen, Chyler Leigh as Alex Danvers, Jeremy Jordan as Winn Schott and Chris Wood as Mon-El.
