The CW Brings Epic Crossover 'DC Week'

(Photo: The CW) DC Week will feature a 4-part crossover event with Supergirl, The Flash, Green Arrow and The Legends of Tomorrow.

Get ready for a week of epic proportion! Starting on Mon. Nov. 28 The CW is bringing a four-part crossover event only suited for the DC world. All of your favorite superheros will be joining forces in each other's worlds (and shows) all next week to take on aliens. It's heroes vs. aliens all week long!

Crossovers like this isn't anything new to the DC world, we've seen many before. The Flash and Supergirl. Green Arrow and The Flash. But we have never seen all of them together, in each other's universes for a whole week. That's why we're calling it: "DC Week."

#DCWeek all starts with Supergirl on Monday when Barry Allen races to National City to get Supergirl's help with an alien problem happening on his Earth. The story continues on Tuesday night's episode of The Flash. The aliens attack, but the team they're facing not only includes The Flash, but Supergirl and the Legends of Tomorrow all join forces.

Don't think it all stops there, we are only part way. The epic-ness continues with a 100th episode celebration for Arrow on Wednesday. Felicity and the recruits take on a new threat, and I bet you guessed who will be there to help them - The Flash and Supergirl.

And finally, on Thursday, the most epic night happens. At 7:00 p.m. on DC's Legends of Tomorrow, the Legends work together with The Flash, Supergirl and Green Arrow to end a threat once and for all.

The CW stars of the shows haven't given too much away on social media about the crossovers, which is only leaving us more on the edge of our seats.

To tide you over until Monday night check out the trailer for the 4-part event above the story.
