We all knew this was coming. SUPERGIRL may have been way off on its own little island on CBS, far removed from the 'ARROW'-verse on the CW, but given that it comes from the same folks, it seemed inevitable that the characters would cross over. About a month ago, that crossover was confirmed, and all we had to do was wait.
We now have our first bit of information regarding the crossover, which will take place on SUPERGIRL (apparently this is currently just going to be a one-sided crossover). You can check out the poster and synopsis below (via Comic Book Movie)
"'Worlds Finest' – 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."
Seems simple enough. After all, the Flash has been hopping around between Earth One and Earth Two in his most recent episodes, it's not completely farfetched that he'd fall into an alternate reality where there's a Supergirl. This does, however, seem to make things a bit difficult for Supergirl to eventually cross over into Flash's world, but that's an issue for another day.
For now, we can all just sit back and enjoy the episode to come. Are you looking forward to this TV event? Let us know in the comments down below!
This crossover episode hits CBS' SUPERGIRL on March 28, 2016!
