The CW is still keeping Supergirl off on her own Earth, so that next weeks’ four-part “Invasion!” crossover will require special intervention from Barry and Cisco to unite Kara with Flash, Arrow and Legends of Tomorrow. That said, the Dominators are already invading a new Supergirl poster for the event, and even Martian Manhunter is joining the fight.

Take this with a grain of salt for the moment, as The CW released the Supergirl portion of what seems likely to be a four-sided crossover mural for each series. And while we do get a better look at the alien Dominators and their ship, Martian Manhunter isn’t expected to make the leap to the Arrow-verse with Kara.

For its part, Supergirl’s November 28 outing “Medusa” will serve as an otherwise-regular episode of Season 2, before Barry and Cisco arrive to recruit Kara, as seen in the mammoth gallery of photos. From there, the rest of the crossover will continue through Tuesday’s Flash, Wednesday’s Arrow, and Thursday’s Legends of Tomorrow.

In addition to the exhaustive gallery of photos above, check out the full synopsis for each leg of the four-night event, the first clip, a trailer below, and stay tuned for more posters from “Invasion!”
