This year’s Arrowverse crossover, “Elseworlds,” wasn’t just a precursor to next year’s “Crisis on Infinite Earths” (although that’s definitely a big deal) – it also finally introduced Batwoman and Gotham into the CW’s superhero universe.

And that probably won’t be the last we’ll see of Ruby Rose’s Batwoman, since The CW is currently developing a potential spinoff series for the Dark Knight’s cousin that’s under consideration for next season.

In our exclusive clip from a behind-the-scenes interview with the executive producers of the Arrowverse, “Elseworlds” crossover, Batwoman EP Caroline Dries explains how the writers sowed the seeds for the possible spinoff series during the crossover episodes.

“Obviously Arkham is this quintessential element of Gotham and so it made sense as we were breaking the story, we have to go there… it made perfect sense also that havoc ensues and all of these criminals get lose and now Barry, Kara, and Oliver have to clean up the mess that they made,” Dries says in the video above. “It was really fun planting these little Easter eggs, figuring out what we could do in the Batwoman series if a couple got loose – introducing [and] featuring a few of the criminals more specifically.”

Fans will be able to see the entire interview in a special feature titled “Inside the Crossover: Elseworlds,” which is available in its entirety with any digital season pass purchase of The Flash: Season 5, Supergirl: Season 4 or Arrow: Season 7, beginning Dec. 14.

\r\nThe very first Crisis story didn\u0027t actually have the word \u0022crisis\u0022 in the name, but it paved the way for every interdimensional team-up that followed. The Flash #123 teamed Barry Allen with his predecessor, Jay Garrick. In the process, this issue established that DC\u0027s long-lost Golden Age heroes still existed, albeit on a different world called Earth-2.”,”height”:720,”width”:1280,”url”:”https:\/\/assets1.ignimgs.com\/2018\/06\/14\/01-1528986605820.jpg”,”styleUrl”:”https:\/\/assets1.ignimgs.com\/2018\/06\/14\/01-1528986605820_{size}.jpg”,”credit”:””,”objectRelationName”:””,”objectRelationUrl”:””,”albumName”:”A History of DC\u0027s Crisis Comics”,”relativePosition”:”02″,”albumTotalCount”:14},{“caption”:”Crisis on Multiple Earths\r\n

\r\n\u0022Flash of Two Worlds\u0022 quickly inspired a trend where Earth-1\u0027s heroes crossed paths with characters from worlds like Earth-2, Earth-3 and Earth-X.

\r\nDC\u0027s first wide-scale Crisis storyline arrived in 1985, as Crisis on Infinite Earths came along to dramatically reshape the fabric of the DC Universe. In this yearlong tale, the heroes of numerous Earths joined forces to battle the Anti-Monitor, a powerful being from the Antimatter Universe bent on devouring all of existence. Numerous heroes gave their lives in this conflict, including Barry Allen and Supergirl.”,”height”:1080,”width”:1920,”url”:”https:\/\/assets1.ignimgs.com\/2018\/06\/14\/03-1528986605831.jpg”,”styleUrl”:”https:\/\/assets1.ignimgs.com\/2018\/06\/14\/03-1528986605831_{size}.jpg”,”credit”:””,”objectRelationName”:””,”objectRelationUrl”:””,”albumName”:”A History of DC\u0027s Crisis Comics”,”relativePosition”:”04″,”albumTotalCount”:14},{“caption”:”By the time the dust settled at the end of Crisis on Infinite Earths, DC\u0027s multiverse was gone.

The goal was to streamline DC\u0027s complicated history and continuity, and many characters were given significant overhauls in the hope of making their comics more accessible to new readers.

\r\nCrisis on Infinite Earths wasn\u0027t wholly successful when it came to streamlining DC\u0027s superhero continuity, and in some ways only served to make things more confusing. Zero Hour was an attempt to address these growing inconsistencies. Fallen Green Lantern Hal Jordan served as the instigator of this conflict, using his power as Parallax to unravel the very history of the DC Universe and rewrite key events. “,”height”:1080,”width”:1920,”url”:”https:\/\/assets1.ignimgs.com\/2018\/06\/14\/dc-comicsgallery-20180502–zero-hour-hc-5ace9c649ea85786185487-1528986605852.jpg”,”styleUrl”:”https:\/\/assets1.ignimgs.com\/2018\/06\/14\/dc-comicsgallery-20180502–zero-hour-hc-5ace9c649ea85786185487-1528986605852_{size}.jpg”,”credit”:””,”objectRelationName”:””,”objectRelationUrl”:””,”albumName”:”A History of DC\u0027s Crisis Comics”,”relativePosition”:”06″,”albumTotalCount”:14},{“caption”:”Identity Crisis (2004)\r\n

\r\nIt would be another decade before DC revived the Crisis brand. Identity Crisis proved to be a very different sort of story, however. Rather than dealing with the state of DC\u0027s multiverse, it followed an elaborate conspiracy sparked by the murder of Elongated Man\u0027s wife, Sue Dibny. Readers learned that the Justice League had a sordid secret of its own, with Zatanna using her magic to mind-wipe Doctor Light after he broke into the JLA Watchtower and assaulted Sue. That led to a pattern of mind-wiping, including even Batman himself when the Dark Knight got wind of his teammates\u0027 actions. “,”height”:562,”width”:1000,”url”:”https:\/\/assets1.ignimgs.com\/2018\/06\/14\/05-1528986605836.jpg”,”styleUrl”:”https:\/\/assets1.ignimgs.com\/2018\/06\/14\/05-1528986605836_{size}.jpg”,”credit”:””,”objectRelationName”:””,”objectRelationUrl”:””,”albumName”:”A History of DC\u0027s Crisis Comics”,”relativePosition”:”07″,”albumTotalCount”:14},{“caption”:”Countdown to Infinite Crisis (2005)\r\n

\r\nIdentity Crisis may not have dealt in cosmic matters, but it did help pave the way for DC\u0027s next major Crisis storyline. That buildup really began in the one-shot special Countdown to Infinite Crisis #1, which showed a badly divided Justice League and resulted in Blue Beetle\u0027s murder at the hands of Maxwell Lord. This issue was followed up by four miniseries, Day of Vengeance, The OMAC Project, Villains United and The Rann-Thanagar War, all of which laid the groundwork for the true Crisis to come.”,”height”:338,”width”:599,”url”:”https:\/\/assets1.ignimgs.com\/2018\/06\/14\/06-1528986605840.jpg”,”styleUrl”:”https:\/\/assets1.ignimgs.com\/2018\/06\/14\/06-1528986605840_{size}.jpg”,”credit”:””,”objectRelationName”:””,”objectRelationUrl”:””,”albumName”:”A History of DC\u0027s Crisis Comics”,”relativePosition”:”08″,”albumTotalCount”:14},{“caption”:”Infinite Crisis (2005)\r\n
\r\n
\r\nAfter months of buildup, Infinite Crisis finally arrived on the 20th anniversary of Crisis on Infinite Earths. In this story, the survivors of the old DC multiverse (Earth-2\u0027s Superman and Lois Lane, Earth-3\u0027s Alexander Luthor and Earth-Prime\u0027s Superboy) resurfaced just as the Justice League was at its lowest ebb. The very act of Superboy-Prime punching his way out of his multiverse prison was used to introduce new changes to the DC timeline. His blows reverberated across time and space, causing changes like Jason Todd surviving his apparent death at Joker\u0027s hands and the classic Doom Patrol being restored.”,”height”:1080,”width”:1920,”url”:”https:\/\/assets1.ignimgs.com\/2018\/06\/14\/07-1528986605843.jpg”,”styleUrl”:”https:\/\/assets1.ignimgs.com\/2018\/06\/14\/07-1528986605843_{size}.jpg”,”credit”:””,”objectRelationName”:””,”objectRelationUrl”:””,”albumName”:”A History of DC\u0027s Crisis Comics”,”relativePosition”:”09″,”albumTotalCount”:14},{“caption”:”Unfortunately, the League came to discover that their recent woes were manufactured by Luthor and Superboy Prime, both of whom sought to destroy the DC Universe and build a better one in its place.

\r\nNo sooner did the finale of 52 reveal that the multiverse had returned than DC began building towards its next major Crisis. 52 was immediately followed by another weekly series called Countdown. Midway through its yearlong run, Countdown\u0027s name was changed to Countdown to Final Crisis.

\r\nDC\u0027s latest Crisis story looks to be more in the vein of Identity Crisis, telling a personal, character-driven story rather than one dealing in cosmic matters.
