Emily Kinney is trading zombies for meta-humans, securing a villainous guest role on The CW’s “The Flash.”

“The Walking Dead” actress will appear in episode 118 of the superhero show, titled “All-Star Team-Up,” which — as Variety first reported — will also feature a crossover with “Arrow,” as Felicity Smoak (Emily Bett Rickards) and Ray Palmer (Brandon Routh) travel from Starling City to Central City so Ray can get some help on his ATOM suit from STAR Labs.

Kinney will play Brie Larvan, a reimagining of the classic DC villain Bertram Larvan, also known as Bug-Eyed Bandit. Brie is a narcissistic tech wizard wreaking havoc in Central City. When Felicity and Ray arrive, Felicity recognizes Brie as her nemesis, and the two women engage in a hacker battle for the Flash’s life.

“In episode four of ‘Flash’ when Felicity came by, it wasn’t just a gag to have Felicity come by. It really was integrated into the story,” previewed “Flash” exec producer Andrew Kreisberg. “When you reach what’s going on in ‘The Flash’ at that point in the season, Barry is really at a crossroads. Having Felicity come by exactly when he needs her really plays into the whole storyline… [And] Ray Palmer is all about technology and STAR Labs is all about technology. We get to see Ray so happy to be in STAR Labs… With Cisco [Carlos Valdes] and Ray, they’re new best friends. The STAR Labs team is going to help Ray further his ATOM project.”

Routh was equally excited about the prospect of crossing over, telling Variety, “I’ve thought about that, because I’m a ‘Flash’ fan for sure — it’s a fun show, and the energy of that show jives more with Ray’s energy, so I think he’ll definitely be a kid in a candy store over there, checking out all of their cool equipment and everything they have going on.”

“The Flash” airs Tuesdays at 8 p.m. on the CW.
