The CW's Supergirl is bringing a new villain to National City, with Kevin Sorbo (Hercules: The Legendary Journeys) signing on for a recurring role as an unidentified new villain. This report comes just days after Teri Hatcher signed on for another unspecified villain role in a multi-episode arc. It remains to be seen if these characters are connected to one another, or when each of their characters will make their debuts on The CW series. In related news, we also have word on when the villainous Mister Mxyzptlk will be showing up on the series.

Deadline broke the casting news about Kevin Sorbo, but they don't have any further details about the character, including if he's a human character or an alien. It also isn't known if this character has any connection to the DC Comics, or if it's a new character being created solely for the show. Given how many notable and iconic DC characters have surfaced on the series, it seems likely that Kevin Sorbo's villainous character does in fact have some roots in the DC Comcis. Here's what executive producer Andrew Kriesberg had to say about Kevin Sorbo's casting.

"Since his days as Hercules, Kevin Sorbo has brought such a strong presence to the screen, and we couldn't be more excited to have him join us on Supergirl."

The CW has also released an official synopsis for their February 20 episode, Mr. & Mrs. Mxyzptlk, which is when the title character will make his debut on the show. Last month, a set photo surfaced that offered our first look at Mr. Mxyzptlk, who will be played by Peter Gadiot, and now we know when he'll be debuting. Even though it debuts a week after Valentine's Day, it seems this will be the show's Valentine's episode. Here's the official synopsis below.

"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."

Mister Mxyzptlk is an imp from the 5th dimension, and he usually arrives to give Superman a hard time. Mister Mxyzptlk has never been considered one of Superman's more dangerous foes. He's usually shown as being more of a nuisance. He doesn't care if people get hurt when he pulls his dastardly pranks though. One time, he even made a Doomsday clone, which didn't work out well for anyone involved. His weapon of choice is usually some kind of elaborate brain game. He appears to have magical powers, but he's actually just using technology he purloined from the Fifth Dimension that does not exist in our world. He can control things through sheer willpower, but it's been discovered that he's easy to prank. If you can convince Mxyzptlk to say his name backwards, he will be sent back to his home for 90s days, unable to visit earth in that time. Stay tuned for more on Supergirl, which returns with the new episode The Martian Chronicles on Monday, February 6 at 8 PM ET on The CW.
