Arrowverse Crossover Sneak Peek: Oliver and Barry Meet Superman!

We're only days away from the epic three-night crossover between The CW's Supergirl, Arrowand The Flash, and frankly, Sunday cannot come fast enough! We're even more psyched after watching the first sneak peek of the crossover!

In this clip that TV Guide and GameSpot are debuting exclusively, we get to see a meet up we've been waiting for ever since Supergirl first premiered!

After waking up in each others' lives, Barry and Oliver seek out their ally, Supergirl (Melissa Benoist), in the hopes that she can help them put their reality back in order, but they didn't intend on bumping into her larger than life cousin when they made the trip to the family farm. That's right! The Green Arrow, The Flash, and Superman (Tyler Hoechlin) officially come face to face -- and we feel like there's a really good Justice League joke just waiting to happen...

Naturally, this is less of a meet-cute and more of a meet-funny. Barry is his usual, adorable self, but he does catch Oliver puffing out his chest in some macho male posturing in their first face off with the Man of Steel. Oliver, he would destroy you, let's not pretend otherwise. It doesn't take them long to clue Kara in on their little predicament though, so let's hope she's got some ideas about how to undo this Freaky Friday they've pulled.

The Arrowverse crossover event kicks off Sunday, Dec. 9 at 8/7c on The CW.

(Full Disclosure: TV Guide is owned by CBS, one of The CW's parent companies.)
