At the CW Upfronts, Mark Pedowitz basically made all our wildest superhero dreams come true: It looks like Supergirl, Arrow, The Flash and the Legends of Tomorrow are all teaming up!

This better be one hell of a bad guy.

On Thursday morning, CW boss Mark Pedowitz confirmed what we’ve all been waiting and hoping for: With Supergirl ‘home’ on The CW, the network is planning a “mega-crossover” of all four of its DC dramas.

Via IGN’s Eric Goldman:

This has been confirmed by EW, who also brings a direct quote from Pedowitz:

“Just imagine what our superhero crossover episode is going to look like come December. [I’ll be] our biggest one ever.”

Whether this means all four shows, we don’t yet know — but we sure hope so!

Not only does this mean that Kara will (probably) meet Oliver Queen, but it also confirms that, however they plan to sort this whole Supergirl being on another Earth thing, they’ve got a crossover plan in motion that includes the latest member of the CWDC team.

Considering recent events on Legends of Tomorrow (whose series finale is tonight), we’d also be very interested in seeing how a certain Captain Cold could factor into this whole thing. For not to mention Katie Cassidy’s Black Siren, who may or may not be popping up as well.

Of course it’s all speculation at this point, and who knows how The CW will be able to pull it off?! But we’re already psyched. We wonder if this will take place across a whole week (with one bit of the episode in each of the shows’ timeslots), or if one or two of the shows will be bringing in the main cast members from everywhere else.
