The CW

What do you get when you mix the heroes and villains from Arrow and The Flash in an underground fight club? Three minutes and ten seconds of absolute perfection!

It's no secret that The CW's two DC-Comics-based superhero series are ass-kickingly amazing, but their newest crossover promo might be the best thing that has ever graced our screens.

Now that Barry (Grant Gustin) is a full-fledged superhero, Oliver (Stephen Amell) decides that it's time that he got a "proper initiation" into their mysterious underground club where they go to let off steam. "Just remember, this club has only one rule," Oliver, dressed in his full Arrow gear, warns. "There are no rules."

The epic promo then features Starling City and Central City's biggest baddies including Ra's al Ghul (Matt Nable), Malcolm Merlyn (John Barrowman), Reverse Flash (Tom Cavanagh), Captain Cold (Wentworth Miller), and Heat Wave (Dominic Purcell), showing off their skills and battling it out against our most beloved heroes.

Punches are thrown, arrows are shot, and heat/cold guns are fired as the fight between good and evil reaches all-new levels of incredible within the walls of the metal fighting cage. The video culminates with a blazing appearance by Firestorm (Robbie Amell and Victor Garber) that greatly impresses the flame-loving Heat Wave.

Take a look at the unbelievably awesome promo in the video above to see all of the badass battles for yourself!

New episodes of The Flash and Arrow air Tuesday and Wednesday, respectively, at 8 p.m. on The CW.
