This coming season of the CW DC shows, Arrow, The Flash, Supergirl, and DC's Legends of Tomorrow, will feature a huge crossover. DC VP of Creative Affairs Dan Evans chats with DC All Access offering some teases, which includes possibly seeing more of the Legion Of Superheroes in Supergirl, as last on Supergirl saw the Legion ring teased and this coming season features Mon-El (played by Vampire Diaries' Chris Wood).

"The direction for The CW shows can be summed up this way," Evans said." It's just going to be epic. We are going to really delve into the entire DC Universe. It's going to be more characters, bigger stories, and we kind of push the boundaries of what we can do on television. This season the big changes are going to be insanely big changes. We are actually changing the fabricate of the universe with Flashpoint. We'll be seeing a whole new set of team members for Arrow. And of course Supergirl coming to The CW will make everything crazy. We kind of hinted, you saw some interlock in the first season, and you saw the Legion ring, now one of the most powerful Legionnaires ever, Mon-El, will be showing up on Supergirl. We don't know what's going to happen from there. It can't be good for everybody. But it also opens a door. Are we going to see more Legionnaires? I hope so."

Evans continued with talk about the big crossover, mentioning comic book fans will love it.

"With CW, they really love and understand what we are doing, and they are so embracing, so loving, that we can go and do the craziest comic book stories," Evans offered. "With this crossover, it's going to take the most understanding of TV executives to make this happen. Comic book fans are going to lose their mind when they find out what the basis for the crossover is. I will say, it's based on a big thing from DC's history. It will justify the crossover, you will not feel cheated."
