8 Characters We’d Love To See On The Flash

8) Supergirl

While it would initially seem a bit farfetched to request that the Last Daughter of Krypton make a trip to Central City and meet up with The Flash, the fact that The Flash producer Greg Berlanti is currently developing a Supergirl series makes it a bit less of a pipedream.

I say a bit less because, despite the Berlanti connection, Supergirl is taking shape over at CBS, not at The CW, which homes both The Flash and its sister show, Arrow. However, we’ve heard a few times now that it’s possible that Supergirl will crossover with the two CW superhero series, so I’m leaving her on this list.

So far, Barry Allen has been the only good-natured metahuman to grace the streets of Central City. The others he’s met up with thus far have all been pretty bad, and either wound up in the metahuman prison underneath S.T.A.R. Labs, or have been killed. Bringing Kara Zor-El – another super-powered individual – into the series would help show Barry that he’s not alone, even if Supergirl’s from another planet.

Add the fact that the two have had some fun (albeit heated) interactions in the New 52, and you’ve got yourself a cool, high-octane episode to look forward to.
