The story of the crossover will based on the DC comic book storyline "Invasion!" in the 1980s and co-producer Marc Guggenheim stated in an interview that they will be using cutting edge prosthetics and computer effects to achieve a feature film-quality look, faithful to comic book artist Todd McFarlane’s interpretation of the characters. The said crossover will center on Supergirl and it is set on Barry's home town of Central City.

Kreisberg added the "Supergirl" season 2 will not only focus on about Fort Rozz aliens, but a whole universe of species, creatures, invaders and explorers that make pit stops on Earth, comparing it to "Men in Black". Supergirl will also fight the mysteriosu Project Cadmus as they are connected to the disappearance of her adopted father, Jeremiah Danvers (Dean Cain).
