Today, The CW is teasing what fans can expect for the upcoming 2018-2019 season -- and it looks like that will involve a major development for the Arrowverse: the introduction of Batwoman.

Comicbook.com was on hand during The CW's recent Upfronts presentation, where Arrow star Stephen Amell announced that Batwoman will be introduced in the upcoming Arrowverse crossover. While it's unclear exactly how Batwoman will factor into the story, it was hinted that Gotham City will make an appearance, finally introducing it into the Arrowverse.

"This is the first time ever that she will make a live-action appearance on any screen," explained The CW president Mark Pedowitz.

Batwoman was first introduced into the pages of DC Comics back in 1956, before Kate Kane took on the mantle in 2006. Since then, the character has developed a pretty passionate fan following, particularly as one of DC's first openly lesbian superheroes. Over the past few years, fans have gotten to see multiple incarnations of Batwoman across DC Comics, most recently in her own solo series, and as a leading member of Bombshells United.

For DC Comics fans, this will surely be a pleasant surprise, as it expands the Arrowverse into some new - and unexpected - directions. For one thing, the introduction of Gotham City comes at an interesting point for DC Television, as Gotham nears its end and new Batman-related television shows go into development. And after the buzzworthy Bruce Wayne namedrop from this season of Arrow, it does sound like Gotham City could end up playing another role.

And once Batwoman is introduced in the crossover -- who knows? Could she end up joining the roster of Legends of Tomorrow? Or could the event potentially set up her own solo series? One thing's for sure, Arrowverse fans will probably be pretty eager to find out.
