“Agents of S.H.I.E.L.D.” announced that comic book superhero Mockingbird would join the cast at San Diego Comic-Con 2014, and they finally cast the role. Former ‘Friday Night Lights’ star Adrianne Palicki will play Barbara “Bobbi” Morse, a.k.a Mockingbird, according to The Hollywood Reporter. This is Palicki’s first time playing a Marvel superhero, but she has worked with DC before.

She starred as Wonder Woman in a failed pilot for NBC in 2011, and she played a villain in the failed “Aquaman” pilot in a 2006 CW pilot. Palicki also guest starred on Season 3 of “Smallville” as a Kryptonian vessel programmed to be Supergirl (the real Supergirl would show up later). Palicki is actually a hardcore comic fan outside of her acting career. She has a Supergirl tattoo, reads comic books and even has a brother who writes graphic novels.

Palicki will first appear in Season 2 of “Marvel’s Agents of S.H.I.E.L.D.” as Mockingbird during episode 5, and it appears that she’ll clash with Director Coulson. This actually fits with her comic book storyline which started with Astonishing Tales #6 in 1971, according to Marvel. The comics showed that Mockingbird clashed with S.H.I.E.L.D.’s security director Clint Barton, a.k.a. Hawkeye. However, Hawkeye eventually married her and made her the first recruit of the West Coast branch of the Avengers.

If she clashes with Coulson instead of Hawkeye, does that mean Coulson could have a new love interest? If that happens, it might not lead to a happy ending. Her relationship didn’t go so well with Hawkeye. After she traveled back in time and killed Phantom Rider (who kidnapped her), Hawkeye broke up with his wife.

At the very least, Mockingbird will likely be the same dedicated S.H.I.E.L.D. agent that she was in the comics. Like Clint Barton and Natasha Romanov, she doesn’t actually have superhero powers, but she is an agent who worked alongside superheroes enough to warrant her own superhero name. In the source material, Director Fury commended her for helping catch a bunch of subversives that had infiltrated S.H.I.E.L.D. Considering the TV version of S.H.I.E.L.D. is still recovering from the Hydra infiltration, Palicki could easily end up portraying a similar story.

“Marvel’s Agents of S.H.I.E.L.D.” will air premiere Tuesday, Sept. 23 at 9 p.m. EDT. Are you excited to see Palicki as Mockingbird? Sound off in the comments section below!
