CBS has revealed the first poster for the upcoming crossover between Supergirl and The CW’s The Flash, as well as the plot details for the episode, airing March 28.
Titled Worlds Finest, the hour sees titular heroine Kara (Melissa Benoist) gain a new ally when the lightning-fast superhero The Flash, aka Barry Allen (Grant Gustin) suddenly appears from an alternate universe. Barry helps Kara battle Silver Banshee, aka Siobhan Smythe (Italia Ricci), and Livewire (Brit Morgan) in exchange for her help in finding a way to return him home.
The Scarlet Speedster already has some experience with alternate universes, having paid a visit to Earth-2 – another version of our world, albeit with some striking differences – in S2 of The Flash.
During that trip, The Flash teed up the impending crossover by including a shot of Benoist’s Supergirl while Barry travelled through the breach between worlds, hinting at a larger DC Comics multiverse that offered endless possibilities on infinite Earths.
While Supergirl and Superman don’t exist on Barry’s Earth-1 – which is set in a continuity known as the “Arrowverse”, since it encompasses all of the superhero shows spawned by Arrow, including The Flash, DC’s Legends Of Tomorrow and animated series Vixen – Barry’s ability to travel through time and space means that he’s capable of paying a visit to other DC Comics-based shows (even on other networks) without disrupting anyone’s reality.
Supergirl also stars Calista Flockhart, Chyler Leigh, Mehcad Brooks, David Harewood and Jeremy Jordan. – Reuters
