On Sunday night, after months of anticipation, viewers finally got to see the first part of the three-night Arrowverse crossover event, "Elseworlds." In the episode, Oliver Queen and Barry Allen dealt with their identities being swapped after reality was rewritten by the Monitor and his puppet, Dr. John Deegan. Thanks to a bit of help from Cisco Ramon, Oliver was able to deduce that the two villains are currently located in Gotham City.
As the episode ended, Batwoman loomed over Gotham City, as Green Arrow, The Flash and Supergirl all prepared to travel to the Bat-family's home city to get some answers. While we already know that the three superheroes will come across Ruby Rose's Kate Kane, there is still the matter of the elephant in the room to address: Batman.
If Batwoman exists, it's because she followed in the footsteps of the Dark Knight. And while we will not see the character in the crossover, we will learn a bit of information about him -- most notably, that he was the Arrowverse's first vigilante, long before Oliver Queen put on a green hood.
In an interview with TVLine, "Elseworlds - Part 2" writer Caroline Dries confirmed that Batman would be revealed as the original masked crime-fighter in the Arrowverse. "We introduce him as being the first vigilante, so it was kind of like poking fun at that a little bit and [Oliver] being defensive."
When Oliver Queen first suited up as the Arrow, it was believed that he was the first superhero in his reality. After all, his appearance would birth a whole universe of characters, both figuratively and literally. The Green Arrow would inspire countless others to fight the good fight, as the Arrowverse would grow to include The Flash, Supergirl and Legends of Tomorrow.
And yet, the revelation that Batman was actually active before him makes a whole lot of sense. If Batwoman is already established as a superhero, it's because the Caped Crusader has been around for a long time -- probably much longer than the Arrow's seven-year career. And it sounds like it will be a lot of fun to see a defensive Oliver Queen react to that information.
This year's Arrowverse crossover event will involve the casts of Supergirl, Arrowand The Flash. The event will unfold over three nights, starting with a special episode of The Flash on Sunday Dec. 9, at 8 p.m. ET/PT. Then, it continues Monday, Dec. 10, with Arrow, and concludes on Tuesday, Dec. 11, with Supergirl.
