The crossover between The CW’s “The Flash” and CBS’ “Supergirl” is almost here! Airing Monday, March 28th at 8pm (EST) on CBS, we will soon see Barry Allen (Grant Gustin) zoom into National City and ultimately help Kara Zor-El (Melissa Benoist) tackle the combined calamatous might of Silver Banshee and Livewire! This episode of “Supergirl“, which is titled “World’s Finest“, will finally 100% pull the series into the DC TV Universe, after a tease a few weeks back on “The Flash“. It joins the likes of “Arrow“, “Legends of Tomorrow“, the animated series “Vixen“, and, of course, the Scarlet Speedster’s own series. Below lies a short, but fun teaser for the crossover…
Here’s the official synopsis for the episode…
Kara gains a new ally when the lightning-fast superhero The Flash suddenly appears from an alternate universe and helps Kara battle Siobhan, aka Silver Banshee, and Livewire in exchange for her help in finding a way to return him home.
