Fans of Supergirl and Legends of Tomorrow might need to get their calendars out because the CW made their lives a bit more difficult.

The shows will be alternating airing new episodes every Monday starting on Jan. 15, when Supergirl returns following its brief hiatus with episode 9 tentatively titled "Legion of Superheroes." From Jan. 15 to Feb. 5, fans will see the Girl of Steel (Marisa Benoist) and her diverse supporting cast's new adventures.

Legends Of Tomorrow Steps In

As Supergirl briefly exits the CW, DC's Legends of Tomorrow will step in and start airing their latest adventures on Feb. 12.  The CW's superhero team is in the middle of a substantial rough patch as the show lost original team members Jefferson "Jax" Jackson (Franz Drameh) and Martin Stein (Victor Garber), who collectively fused together to form one of the Arrowverse's most powerful heroes: Firestorm.

Garber announced that he would be exiting the CW television series to star alongside Bernadette Peters in Hello Dolly. Legends of Tomorrow will air its season 3 finale on Monday, April 9. Supergirl will make her triumphant return to the CW on Monday, April 16.  

Black Lightning Debuts

TV insiders state that DC's Legends of Tomorrow and Supergirl will air at alternate times so that it could accommodate the upcoming DC Comics superhero series Black Lightning. The new series focuses on former superhero Jefferson Pierce (Cress Williams), who is forced to come out of retirement when mobster Tobias Whale (Marvin "Krondon" Jones III) threatens Pierce's neighborhood. Williams and Jones III are joined by China Anne McClain and Nafessa Williams as Pierce's daughters: Jennifer and Anissa. Black Lightning will premiere on Tuesday, Jan. 16 following The Flash.

Supergirl's Startling Situations

Since Supergirl moved to the CW from CBS, the superhero show has been through some growing pains. While she was firmly placed in the Arrowverse and did have a Superman (Tyler Hoechlin), fans have been slowly leaving the series due to several developments such as the inclusion of Lena Luthor (Katie McGrath) over her wicked half-brother, Lex Luthor.

The show also came back in the news when Warner Bros. Pictures suspended show producer Andrew Kreisberg due to 19 allegations of sexual harassment. In fact, Benoist turned against Kreisberg publicly on social media.

"When people commit crimes or harass others, they should always be held accountable," tweeted Benoist. "I've spoken up about it in the past ... and I'll continue to do so."
