The Scarlet Speedster and Supergirl’s worlds are set to collide when Barry Allen/Flash (Grant Gustin) zooms over to National City in an epic The Flash/Supergirl crossover episode.
Which is made even more epic by the fact that both comic-book shows are on different networks, with The Flash airing on The CW and Supergirl on CBS. (By the way, did you catch the Supergirl cameo in this week's Flash episode "Welcome to Earth-2"? That, too, was pretty epic.)
In order to whet our appetite, Gustin has shared a new pic on his Instagram account featuring himself in his Flash costume and Melissa Benoist suited up as Supergirl with the caption: “Those two emblems look pretty good together…”
Pretty good indeed! Check it out:
While we know Grant Gustin will guest-star as The Flash on Supergirl’s March 28 episode titled “Worlds Finest,” there are no details as to how and why Barry Allen will pop up in Kara’s world.
