Arrowverse Crossover Photos: Thea Suits Up, Caitlin and Iris Meet Supergirl

So. Many. Superheroes.

The CW has released a big batch of photos from its upcoming crossover between Supergirl, The Flash, Arrow and Legends of Tomorrow, and it is chock-full of costumed crimefighters — and their trusty pals! (Yes, The Flash‘s Iris and Caitlin are also present at the super meet-up.)

Other takeaways from the first-look photos:

* It’s all hands on deck as the heroes battle the alien race the Dominators, so even Thea suits back up to pitch in.

* Cisco looks very happy to meet the Girl of Steel. Crush alert?

* Supergirl seems charmed by HR.

* Mick and Kara. Enough said.

The crossover event kicks off at the tail end of Supergirl‘s Nov. 28 episode (8/7c), and continues all week on The Flash (Tuesday, Nov. 29 at 8/7c), Arrow (Wednesday, Nov. 30 at 8/7c), and Legends of Tomorrow (Thursday, Dec. 1 at 8/7c).
