When the CW's lineup of superhero shows returns in the fall, their number will have increased. "Supergirl" has zoomed over from CBS to join "Arrow," "Flash" and "Legends of Tomorrow" on the network, increasing the shared superhero universe to four concurrent series. And, as is tradition with the shows, the fall will see a crossover between the quartet of shows.

In an interview with MovieFone, "Legends of Tomorrow" star Caity Lotz expressed her excitement about the upcoming crossovers. "Yes, crossovers are what I'm most excited for, just because the potential of that! I want to go on 'The Flash.' I want everybody to come on to our show," said Lotz, who plays the White Canary on "Legends."

Lotz also has two specific characters she wants to fight. "I want to see, like, especially with Earth-2 on 'Flash,' I think it'd be really cool to kind of see [White Canary's sister] the Black Siren, which is Katie Cassidy. I want to see Katie Cassidy and Danielle Panabaker's evil alter egos. I want to go head-to-head with them."

The actress also wouldn't mind seeing the Earth-2 alter-ego of her all-action assassin character, Sara Lance. "I'd be, like, a librarian, or I knit scarves. That's what Sara does in Earth-2."

There is one development Lotz teased about season two of "Legends of Tomorrow," and it involves Sara Lance's love life. "I think Sara might get a new girlfriend!" While further details about Lance's potential romance have not been revealed, Lotz did touch on White Canary's ex Nyssa al Ghul. While actress Katrina Law will be appearing on a new show, "Training Day," Lotz says Law "worked it in her deal so that she could come and see us!"

"Legends of Tomorrow" returns to the CW for its second season on Thursday, October 13 at 8 PM ET.
