Sasha Calle's Supergirl managed to make a splash in the first full-length trailer for The Flash, although there is no word on whether or not she'll continue to play her under the watchful eye of James Gunn and Peter Safran.
If Calle does get rave reviews and vocal fan support for her role as Kal-El's cousin, it's a straightforward process to remove the actress from the DCU when the film is released this summer.
However, those who are not particularly familiar with DC's comic book history have been thrown for a love, with the mention of the superhero's earthbound alter ego raising eyebrows for its similarities to Brie Larson's in Captain Marvel's astonishingly divisive manner.
Although Supergirl made her debut on the big screen in 1984, Halle Berry's Catwoman is considered as DC's worst-reviewed live-action film of all-time.
At the end of the day, not everything needs to be boiled down to a Marvel vs. DC debate, but it always has been, and it will continue until the dust settles on The Flash.
