Everybody is ready to take on the newest threat. We may not know much about the Dominators, but we're pretty sure they are no match for The Flash, The Green Arrow, Supergirl, and the Legends. We will have to watch and see!
Are the Dominators attacking from above? They're all looking up at something, though Supergirl seems to be checking something out of the corner of her eye. Her ability to fly might come in handy.
It's been awhile since Professor Stein made an appearance on The Flash, but that doesn't mean he's been forgotten. His help will be much appreciated by his old friends.
The crossover is full of visitors, but we can't forget those who have been by Barry's side since the beginning. Cisco and Kara will meet on Supergirl, but the fight begins on The Flash. It looks like she's the only one staying in costume.
Atom is ready to put that awesome new suit to good use! The timing couldn't be much better as he and Speedy come to the aide of Barry and Oliver. He should have everything he needs to take on the Dominators.
Supergirl looks ready to lead this ragtag team of heroes into battle. Previously she'd only met Barry, and had no idea just how many superfriends he had. These Legends are ready to back her up.
Barry is surrounded by fire and debris from what we have to assume is a pretty epic battle. Could this the first attack that drives him to call his superfriends for help?
Oliver has always been there for Barry, and this time is no different. The two heroes are ready for battle, and they'll always have each other's backs. In this case, it appears to be two against one, but that could be misleading.
Barry knows he can't do take the Dominators on his own, and he calls in reinforcements. Supergirl, being an alien herself, seems to be leading the charge.
