It's the annual tradition of The CW's Arrow-verse to hold a multi-show crossover with an enormous villain that takes the heroes of every show to defeat. Elseworlds will be a bit different than the past crossovers, which we'll discuss later, but will also be a landmark for the network in so many ways.
Though details have been kept mum until relatively recently, the Elseworlds crossover event will air the 9th, 10th, and 11th of December.
There will be no Legends of Tomorrow
For the first time since the premiere, Legends of Tomorrow will be sitting out on the crossover action. Instead, The Flash will switch slots with Supergirl, airing Sunday at 8/7c, followed by Arrow on Monday at 8/7c, and Supergirl on Tuesday at 8/7c.
That said, the cast and crew of Legends have said they're doing their own little crossover during their regular time, but it'll be sticking to its own characters for this "special" event. So, don't be sad! Honestly, there isn't enough room to properly engage every hero in the Arrow-verse, so the Legends are the most likely group to actually sit out. Who knows, maybe they won't need Supergirl's help next year since she's on Earth-38?
Oliver Queen is... the fastest man alive?
The writers better have a good idea of what they're doing because, honestly, we're lost. According to set photos and the poster released, Oliver will be the Flash and Barry will be the Green Arrow. At least, Stephen Amell will be stepping into the Flash suit and vice versa for Grant Gustin. (Maybe this will put the body shamers who criticized Grant Gustin earlier this year on mute for a while.)
Could the two switch bodies? Based on the tweet below from Amell, it's certainly likely.
There might even be multiple versions of Oliver and Barry as Amell also posted a photo of him and Gustin dressed in what people are calling "biker" attire.
This will be Batwoman's introduction to the Arrow-verse
Since the announcement that Ruby Rose will be playing Kate Kane AKA Batwoman in the Elseworlds crossover, and potentially going off to her own series for the 2019-20 TV season, her appearance is highly anticipated. How will Rose live up the mantle?
It's unclear exactly what role she'll play, but likely that this is the closest the DCTV universe will ever come to Gotham City and Batman, so it's likely they'll be pulling from Batman's comic history as they do with Superman and Supergirl.
With Barry and Oliver switching mantles, it might be likely to presume that Kara and Kate may end up doing the same in whatever world they're in?
It would make sense; Superman and Batman are always compared, so why not Supergirl and Batwoman? In this universe, that'd be the most logical swap.
Lois Lane and Clark Kent are coming to town!
Earlier this month, it was announced that Elizabeth Tulloch (Grimm) had been cast to play Lois Lane, the hard-hitting reporter at the Daily Planet with whom Cat Grant holds a deep resentment.
It was also announced that Tyler Hoechlin would be reprising his role as Clark Kent for the upcoming crossover, but it's still unclear what role his character will have, especially since we've seen him in two different costumes.
With all of the amazing characters and twists (that we know about), people are getting hyped for Elseworlds! Will you be tuning in? We certainly will! This is going to potentially be the best crossover yet!
