In the comic book world, Superman and The Flash have raced numerous times to determine which of them is the fastest man in the world. But later this month, Supergirl and The Flash are going to find out who the fastest person is!
Grant Gustin is slated to appear on CBS’ Supergirl TV series as Barry Allen a.k.a. The Flash in “World’s Finest,” a stand-alone story that finds Barry temporarily trapped on Supergirl’s Earth. But that’s not going to stop the two heroes from having a little lighthearted fun! In a new preview clip from the episode, the Flash and Supergirl (Melissa Benoist) recreate some of that Silver Age magic as they line up to race.
On your marks…
Get set…

Here’s CBS’s official description of the episode:
“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.”
For now, this is only a one way crossover, as Benoist isn’t expected to return the favor and appear on The Flash this season. But who’s to say that she won’t show up at some point on The Flash season 3? Supergirl has also been renewed, which means that a second crossover is entirely possible.
The Flash will appear on Supergirl on Monday, March 28 on CBS.

Put Your Mask on, Barry!
Seriously, dude. You're worse than Tobey Maguire's Spider-Man. At least his mask was damaged when it came off...all the time.
