CBS has unveiled a new poster (above) for the upcoming Supergirl and The Flash crossover episode, titled: ‘World’s Finest’.

The poster, featuring stars Melissa Benoist (Kara/Supergirl) and Grant Gustin (The Flash), is a parody of the cover of Superman comic #199. Benoist’s Supergirl co-stars David Harewood, Chyler Leigh, Calista Flockhart, Jeremy Jordan and Mehcad Brooks also feature on the sidelines.

Episode 18: ‘World’s Finest’, sees Kara gain 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.

The Flash and Supergirl crossover is set to air on CBS in America on Monday, 28th March. Sky 1 shows both shows in the UK but is yet to announce when they will air the crossover episode.
