A fan favorite Smallville character is coming to the Arrowverse for Legends of Tomorrow Season 3.

In a recent interview with Rotten Tomatoes, Arrow and DC’s Legends of Tomorrow Executive Producer Marc Guggenheim revealed that an “established” DC character “who is not from the comics” would be joining the Legends of Tomorrow series in Season 3.

“We’re drawing on an established character who is not from the comics,” Guggenheim said. “Let me be very clear: not original to the show but not from the comics and not from any of the other DC Arrowverse shows.”

You’re probably wondering why we’re reporting on this at KryptonSite: It’s because this website, long before Supergirl, was considered the Web’s first source for Smallville news and information… and the Legends mystery character actually originated on Smallville.

Do you want to know what’s happening?

SPOILERS, obviously.

KryptonSite has learned that the character who is showing up is the one who might be one of Smallville’s most enduring creations: Chloe Sullivan. As played by Allison Mack, Chloe was the show’s “Lois Lane” before Lois actually came to the show. She was smart, fun, witty, and a great friend and confidante to the show’s Clark Kent….

….and now she’s going to be a regular character in Legends of Tomorrow Season 3.

We’ve heard that Smallville creators Alfred Gough & Miles Millar are receiving a royalty for this, and that if all of the pieces come together, it might even be Allison Mack reprising the role. So far, the actress has not been approached as the producers are still laying out Legends’ third season; our sources say producers are “very interested” in casting her, and that if she accepts, then yes, we will at some point get that Chloe Sullivan-Felicity Smoak meetup of our fanfiction dreams.

Chloe Sullivan has appeared in DC Comics continuity, at least prior to the “New 52” initiative; however, she did first appear in other media, having originated on Smallville.
