“Marvel’s Agents of SHIELD” has cast Adrianne Palicki as Marvel hero Bobbi Morse (aka Mockingbird) in season 2, Variety has confirmed.

Mockingbird is described as a super-spy who will make her first appearance in the fifth episode of “SHIELD’s” second season — but she may not be an ally to the newly promoted Director Coulson (Clark Gregg) and his team.

It’s not Palicki’s first superhero role — the “Friday Night Lights” alumna starred as the titular heroine in NBC’s ill-fated “Wonder Woman” pilot, and appeared in The CW’s scuttled “Aquaman” pilot in 2006. She reunited with “FNL” showrunner Jason Katims last season for a recurring role on NBC’s “About A Boy,” which she will reprise in season two.

Palicki joins other season 2 cast additions including Lucy Lawless as Isabelle Hartley, a veteran SHIELD agent; Nick Blood as mercenary Lance Hunter; Reed Diamond as Daniel Whitehall, a HYDRA agent known as the Kraken; Henry Simmons as SHIELD agent Alphonso “Mac” Mackenzie, and Simon Kassianides as Bakshi, a loyal right-hand man.

The introduction of Mockingbird was teased at the show’s recent Comic-Con panel in San Diego, where she was mentioned in a video clip featuring two of Patton Oswalt’s Agent Koenig characters.

Palicki is repped by WME and Anonymous Content. “Marvel’s Agents of SHIELD” premieres Tuesday, Sept. 23 at 9 p.m. on ABC.
