The CW has released an update to last year’s Superhero Fight Club, this time bringing Supergirl into the group.

While the original Superhero Fight Club featured heroes versus villains, Superhero Fight Club 2.0 features all heroes from Arrow, The Flash, Legends of Tomorrow and Supergirl, both in the ring and watching from a control room.

The conceit is that the Green Arrow and Flash have brought Supergirl into the Superhero Fight Club — but she let them kidnap her! — and this time the heroes must fight Cisco and Felicity’s dangerous machine.

And don’t forget the upgrades from the original Superhero Fight Club. After all, they have to allow for Supergirl’s impressive abilities.

While the Green Arrow, Flash, Supergirl, White Canary, Firestorm and Atom fight off the machines, Cisco, Felicity, Diggle and Hank Henshaw/J’onn J’onzz watch from afar. Diggle, unsurprisingly, has a hilarious reaction to J’onn’s true identity.

The final moments of the video feature a surprise cameo that should have fans cheering.

Superhero Fight Club 2.0 serves as a teaser for the upcoming four-way crossover between the shows that will air later this fall. We learned today that the villain that will unite the heroes from all four shows will be The Dominators, an alien race from the edges of the universe.

The Flash season 3 premieres Tuesday, October 4. Arrow season 5 premieres Wednesday, October 5. Supergirl season 2 premieres Monday, October 10. Legends of Tomorrow premieres Thursday, October 13. Each airs at 8:00 p.m. on its respective night on The CW.
