Legion of Super-Heroes Arrives in New Supergirl Promo

We learned in September that after a brief tease in Season 1, DC Comics' Legion of Super-Heroes would finally make their debut on The CW's Supergirl when it was announced that Amy Jackson had been cast as Saturn Girl. Now, in the latest promo for the soon-to-return series, we have our first look at the 31st-century heroes assembling on-screen... Sort of.

In the promo, we get a brief shot of three hands, each sporting the iconic Legion Flight Rings, coming together in solidarity. We don't actually get a look at the faces of the characters in question, but they're presumably Chris Wood's Mon-El, the aforementioned Saturn Girl, and Defiance alum Jesse Rath's Brainiac-5, who's poised to make his debut in the aptly titled midseason premiere episode "Legion of Super-Heroes."

The Legion of Super-Heroes’s existence in Supergirl‘s reality was initially teased in the show’s first season, when viewers saw a Legion Flight Ring on display in Superman’s Fortress of Solitude. The teases continued following the Season 2 finale, when series star Melissa Benoist stated in an interview that the Legion Ring would make its return at some point. Additionally, Mon-El — a character frequently associated in DC Comics with the Legion of Super-Heroes — became a major part of the show in Season 2, and has since returned after disappearing in the finale.

In the comics, not only does Supergirl travel to the 31st century where she meets and becomes a member of the Legion of Super-Heroes but it’s also where the character strikes up the defining romance of her life with fellow Legionnaire Brainiac-5, a descendant of Superman’s foe. According to former co-showrunner Andrew Kreisberg, that relationship will likely carry over into the television series, as well.

Returning Monday, Jan. 15 at 8 p.m. ET/PT on The CW, Supergirl stars Melissa Benoist as the Girl of Steel, David Harewood as Martian Manhunter, Mehcad Brooks as Jimmy Olsen, Chyler Leigh as Alex Danvers and Jeremy Jordan as Winn Schott, with appearances by Calista Flockhart as Cat Grant and Tyler Hoechlin as Superman.
