Supergirl won't be appearing in "Arrow" or "The Flash" any time soon.
Executive producer Greg Berlanti previously suggested that Kara Danvers could cross over and team up with Oliver Queen or Barry Allen, but he has now downplayed that idea, reported Variety.
"The network (CBS) has said publicly at this point they're going to keep her to themselves," Berlanti said.

"I always approach the shows as a fan first, so I would love to see a crossover. I think in success, all things are possible. But there's a lot that would have to happen before everybody might say yes to that."
"Supergirl", starring "Whiplash" and "Glee" actress Melissa Benoist in the titular role, will launch on CBS in November.
Mehcad Brooks, Calista Flockhart, David Harewood and Chyler Leigh are also part of the main cast.
