With just six days left until the Supergirl mid-season premiere, which kicks off four weeks of new episodes before a lengthy Supergirl hiatus, The CW has debuted the first look at a suited-up Mon-El (Chris Wood). While the character has been an integral part of the show since debuting in the Season 2 premiere, this photo marks the first time we've seen him wear his Legion of Superheroes costume, and he'll be one of the key heroes to help save National City from Reign (Odette Annable). Here's the official plot synopsis for the Season 3 mid-season premiere, fittingly entitled Legion of Super-Heroes.

"Struggling to heal from her injuries inflicted by Reign, Supergirl remains in a dreamlike state, unable to be reached. Mon-El recruits one of the Legion members, Brainiac-5, to try to bring her back. Meanwhile, Reign continues her rampage on the city so the DEO teams up with the Legion of Superheroes to try to stop her."

Supergirl has remained rather faithful to the Mon-El story line from the comics, where Mon-El suffered from lead poisoning that lead to him being placed in the Phantom Zone until Brainiac-5 discovered a cure in the 30th Century. At that time, Mon-El joined the Legion of Superheroes under the name Valor. While it remains unclear if he'll go under the Valor moniker, the show featured Mon-El leaving Earth after the release of a lead dispersal device, and after accidentally going through a wormhole, he ended up in the 30th Century, where he's a member of the Legion and also married to Saturn Girl (Amy Jackson). Jesse Rath is slated to make his debut as Brainiac-5 on the mid-season premiere.

Supergirl Season 3 will go into a rather lengthy hiatus after its February 5 episode, with Legends of Tomorrow taking over for a nine-week stretch between February 12 and April 9, before Supergirl returns to round out its season from April 16 to the Season 3 finale on June 18. Many fans had been worried that this extended hiatus for Supergirl meant the network had a lack of confidence in the show, but that was not the case at all. The CW president Mark Pedowitz had said in the past that he did not want to air all five of the network's superhero shows at one time, including the upcoming Black Lightning, because he didn't want fans to suffer from superhero "overload." He added that fans should not be worried at all and that everyone at the network are, "big believers" in the series.

There has also been a significant shake-up behind-the-scenes as well, with The CW suspending producer Andrew Kreisberg from Supergirl, along with Arrow, The Flash and Legends of Tomorrow, over sexual misconduct allegations. This lead to Melissa Benoist issuing a poignant statement where she dedicated herself to helping provide a, "safe, respectful and collaborative space."
