SPOILER WARNING: This article contains major spoilers for "Shelter from the Storm," the latest episode of Supergirl.

Supergirl's Legion of Super-Heroes just keeps growing. In "Shelter from the Storm," the latest episode, Mon-El and Saturn Girl confirmed another member of the team: Chameleon.

In the comics, Chameleon Boy is a Durlan. Like the rest of his species, he has the ability to shapeshift, earning him his moniker and a spot on the Legion Espionage Squad. He debuted in the 1960 comic Action Comics #267 by Otto Binder and Wayne Boring.

Though Chameleon exists in Supergirl's present, he didn't actually appear in the episode. He remains in stasis on board the Legion's ship, where he will stay until the Legion develops a cure for the Blight's disease. As of "Shelter from the Storm," he, Imra and Brainiac-5 are on their way back to the future, while Mon-El stays behind to battle Reign with Supergirl.

Airing Mondays at 8 p.m. 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.
