'Crisis on Infinite Earths' might drastically change 'Supergirl' and 'The Flash' by collapsing The CW's DC multiverse
Irrespective of who survives and who dies, the Arrowverse will be a drastically different place post-Crisis. Even if our heroes manage to avoid a full reboot, fans can expect to see all the shows change drastically to accommodate the effects of the event.
With ‘Crisis on Infinite Earths’ looming on the horizon, Arrowverse fans are hotly debating which heroes will survive the event and which ones will have to make the ultimate sacrifice. But even if all our beloved superheroes manage to survive the "Crisis," the comics suggest the event will have huge consequences for the Arrowverse as a whole.
The aftermath of the ‘Crisis on Infinite Earths’ comic book event saw the collapse of the multiverse. All the infinite parallel worlds that made up the DC multiverse were condensed into a single Earth, now populated by beings who were initially part of different universes but who no longer remember their past lives.
If the CW shows pull off a similar merging of universes, we could see Supergirl moving from her current home on Earth-38 to the main universe, which would allow her to work more closely with her friends the Flash and Batwoman. Unfortunately, this could actually add more problems for our heroes to deal with as well.
With the good comes the bad and even if the "Crisis" gives Earth-1 their own versions of Superman and Supergirl, the event could also lead to villains from other universe coming into the prime universe. Post "Crisis", the Arrowverse could introduce brand-new versions of familiar villains and the best part is that the heroes wouldn’t even realize the difference. We might even see reappearances of characters from the dystopian Earth-X, where the Nazis won World War II.
There’s no way the Arrowverse can go through ‘Crisis on Infinite Earths’ without making massive changes to the shows. For one thing, now that ‘Arrow’ is officially coming to an end, fans will have to come up with a whole new name for the shared multiverse of The CW superhero shows including 'Supergirl', 'The Flash', 'Legends of Tomorrow' and 'Batwoman'. If the "Crisis" does condense the multiverse down to one universe, we could be looking at a network-wide soft reboot of all the CW shows.
There’s even a chance ‘Black Lightning’ could be brought into closer contact with the rest of the CW’s DC properties, though the show has so far stayed away from those characters. In the world of ‘Black Lightning’, the Flash and Supergirl are nothing more than comic book characters. That’s unlikely to change but it is hard to imagine how the series can expect to ignore the massive world-ending event going on in its sister shows.
Irrespective of who survives and who dies, the Arrowverse will be a drastically different place post-Crisis. Even if our heroes manage to avoid a full reboot, fans can expect to see all the shows change drastically to accommodate the effects of the event. What those changes might be, we won’t know until the event hits screens but we do know the world will never be the same again.
The first season of 'Batwoman' will begin airing alongside the fourth season of 'Supergirl' on The CW October 6, while 'Arrow' Season 8 and 'The Flash' Season 6 will begin airing on the network October 15 and October 8 respectively.
