Batwoman is coming to The CW's DC universe.

At The CW's Upfronts presentation on Thursday morning, Arrow's leading man, Stephen Amell took to the stage with a big announcement.

“We’re incredibly excited to announce that we’ll be doing another crossover event this fall on the CW, and we’ll be introducing a new character,” Amell said.

“For the very first time appearing, we’ll be fighting alongside Batwoman, which is terrific. The crossover is going to make it to air in December."

"I need to leave right now and start filming it.”

And that's not all.

“We are adding the city of Gotham into the Arrowverse,” CW boss Mark Pedowitz confirmed. “This will be another full-throttled action-packed event.”

"This is the first time ever that she will make a live-action appearance on any screen," continued Pedowitz.

All of the details are very surprising because it's taken so long to actually come to fruition.

On The Flash Season 1, a newspaper revealed Wayne Tech merged with Queen Inc. in the year 2024. Then, on Arrow Season 6, Oliver tipped the hat to Bruce Wayne when everyone was questioning who really is Green Arrow.

This revelation confirmed that both characters exist in the same universe. There's no word yet on whether Batman will actually appear on the crossover, but the inclusion of Batwoman should make for a fun dynamic.

The CW's superhero slate currently includes Arrow, The Flash, DC's Legends of Tomorrow, Supergirl and Black Lightning.

Could a sixth series be ready to join in on the fun? We have no idea at this stage, but with Gotham coming to a close on Fox during the 2018-2019 season, this might be why The CW is laying the groundwork for stories in Gotham City.

All things considered, this is a great way to market the next crossover. There will be a lot of curiosity from viewers as they will want to see what the first live-action version of Batwoman looks like.

Okay, Arrowverse Fanatics!
