Supergirl is on her way to CW, and she will become a part of the DC Comics lineup on the network. This now opens the door for an even bigger crossover event next season. This comes from Mark Pedowitz.
According to Entertainment Weekly, he revealed that fans of the DC world on television will see all four CW shows combine for one huge crossover event in December. Supergirl will join The Flash, Arrow, and DC’s Legend of Tomorrow for the event.
Pedowitz called the planned crossovers its “biggest ever.” He also said that Supergirl should have always been on CW and not CBS. The first season of the series aired on CBS, and it did feature a crossover between The Flash and Supergirl. That crossover event gave Supergirl a big boost in the ratings that night.
