When “Marvel’s Agents of SHIELD” returns to ABC this fall, the hit show will venture further into comic book territory by introducing characters inspired by Marvel’s “Secret Warriors,” Variety can exclusively reveal.

As Marvel fans know, in the comics, the Secret Warriors are a team of superpowered agents assembled by Nick Fury — including Daisy “Quake” Johnson (played by Chloe Bennet on the show). These special individuals are drawn from Fury’s Caterpillar initiative (which eagle-eyed viewers may have spotted an easter egg for in the season two finale) — made up of people with potential abilities who have remained hidden and thus are less likely to be compromised by their enemies.

Season three of “SHIELD” will introduce new friends and foes based on the “Secret Warriors” comic series when it premieres on Sept. 29. In the aftermath of SHIELD’s battle with Jiaying and the Inhumans, Director Coulson (Clark Gregg) will search the world for more powered people and assemble an extraordinary new team to deal with threats unlike the world has ever seen. However, the Agents of SHIELD will soon find out they’re not the only ones tracking down these new Inhumans.

Since Coulson and his team are already seeking out new recruits, ABC and Marvel are launching their own initiative at San Diego Comic-Con, giving fans a chance to be part of the team. From Thursday, July 9 through Saturday, July 11, SHIELD ambassadors will be roaming the convention to find the most dedicated fans and rewarding them with limited edition “Secret Warriors” pins. You can track the ambassadors on Twitter by following the @AgentsOfSHIELD account.

Fans who find themselves recruited to the “Secret Warriors” at Comic-Con will complete their first mission by posting a photo of themselves wearing the pin to social media using #SHIELDSecretWarriors, after which, “Marvel’s Agents of SHIELD” cast members will select some of their favorite photos, which could get posted to the show’s official Twitter page, @AgentsOfSHIELD. (Terms and conditions here.)

More will be revealed about “Secret Warriors” and season three of “MAoS” during the “Marvel Television Presents” panel at SDCC on Friday, July 10 from 3:00 PM – 4:15PM in Ballroom 20.

“Marvel’s Agents of SHIELD” returns to ABC on Tuesday, September 29 at 9 p.m.
