CBS dropped yet another promo today for their superhero collaboration Supergirl and The Flash! The promo teases a race between the two superheroes, with both of them getting set to race for the title of Fastest’s Person Alive! The two heroes will collide on episode 18 of Supergirl entitled ‘World’s Finest’. The official plot synopsis goes as follows:

“Kara gains a new ally when the lightning-fast superhero The Flash (Grant Gustin) 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.”

Check out both promos below, as well as plenty of behind the scenes photos which not only show our heroes but offer our very first look at Banshee as well!
