Stargirl and Reverse-Flash are making their way to the CW-verse this fall, but if you blink during the latest Legends of Tomorrow promo, you might miss them.

The DC television universe will soon be at its biggest. In Season 2 of Legends of Tomorrow, the Justice Society of America and Legion of Doom will clash while Rip Hunter’s ragtag team are caught in the middle — and Stargirl and the evil Reverse-Flash will be there, too.

Stargirl, a star-spangled whippersnapper played by Sarah Grey is one of the JSA superheroes who seek the help from Rip’s crew aboard the Waverider. Meanwhile, Matt Letscher will reprise his role as Eobard Thawne, aka the Reverse-Flash, from Season 1 of CW’s The Flash. Thawne has joined the Legion of Doom, and is ready to pit his formidable speed against the Legends and the JSA alike.

Both of these series newcomers make a really, really quick appearance in the Season 2 promo posted on the show’s social media channels. Aside from these first appearances, there are also instances of the show’s upcoming adventures: Sara beds the Queen of France, they attempt to kidnap Albert Einstein, and they show up in the dark ages and fight an executioner (is it a version of Willy Hooker from Earth-2?). Yeah, Legends of Tomorrow is a wild show and you should totally be watching.
