EXCLUSIVE: Supergirl Will Appear in ‘Batwoman’ Season 1

It has been a crazy weekend for fans of The CW‘s Arrowverse. FandomWire broke the news that Black Lightning would be appearing in Crisis on Infinite Earths, which was confirmed by the actor himself, Cress Williams. Today we were gifted with official air dates for each of the five episodes of the crossover as well as news of Kevin Conroy being cast as an older version of Batman.

Crisis on Infinite Earths is shaping up to be the gutsiest but most impressive crossover we have seen yet. Newcomer to the Arrowverse, Batwoman (played by John Wick: Chapter 2 star Ruby Rose) made her debut in last winter’s crossover, Elseworlds. Elseworlds worked as an introduction to her character and set her up for her own show, Batwoman, which airs this October.


Batwoman is pulling double duty this year! The show has to establish the grounded nature of a whole new Batman-esque part of this universe; as well as, not only participating in, but being an important element of, another mind-boggling, universe hopping crossover event.

Sorry that was kind of wordy.

But it turns out that Ruby Rose’s Batwoman will have a little help in the form of a familiar face. Sources close to FandomWire are telling us that Melissa Benoist’s Supergirl will be hopping over to Earth-1 at some point during the first season of Batwoman to lend a hand. This will likely further connect Batwoman to the larger Arrowverse as well as set up the Crisis on Infinite Earths event later in the season.

Crisis on Infinite Earths will take place over the course of 5 episodes starting with Supergirl, followed by Batwoman, and then The Flash on December 8th, 9th, and 10th respectively. The first 2/5ths of the event will likely highlight the further solidified (and sometimes flirty) friendship our two superheroines that started in Elseworlds.

The CW will no doubt leave us on a massive cliffhanger with the last two episodes not airing until after the midseason break, with Arrow and Legends of Tomorrow airing on January 14th.


The Arrowverse, named as such because of it’s flagship series Arrow, has been hinting at the death of Stephen Amell’s Oliver Queen. Arrow‘s 8th and final season will air on October 15th, 2019. The season will only have 10 episodes… it’s last being its Crisis on Infinite Earths episode.

With rumors of Crisis on Infinite Earths ending with Supergirl joining the rest of our heroes on their earth, (potentially through Earth-38 somehow combining with Earth-1?) it’s increasingly likely that the future of the Arrowverse will focus on the yet untapped Batman and Superman mythos surrounding our two superheroines.
