Inhumans aren’t heading to the big screen any time soon, but they’ll still be on “Marvel’s Agents of S.H.I.E.L.D.” Earlier this summer, Marvel Studios announced that “Inhumans” no longer has a release date. The disappearance from the studio’s movie schedule apparently gives the ABC TV show rights to more comic book characters.

“We do have a little more freedom,” executive producer Jed Whedon told Gizmodo. “We’ve told a couple of seasons of stories but now we do have some more freedom. So when we return to focusing on Inhumans, we’ll be able to do a little bit more.” He and executive producer Maurissa Tancharoen also said they’d be able to utilize “some of the classic Inhumans.”

Daisy Johnson/Quake (Chloe Bennet) is actually a much newer Inhuman in the Marvel comics, but this means some of the older characters will be allowed on the drama in Season 4. Presumably, when they say “classic Inhumans,” they mean the Inhuman Royal Family. These are the members we’d most like to see with Coulson’s (Clark Gregg) team:

Black Bolt — This character is often silent because his voice is his power. His “quasi-sonic scream” can be as powerful as a nuclear weapon, according to Marvel. However, he has plenty of other powers including energy blasts, flight and the ability to manipulate matter. As a member of the Illuminati in the comics, he was regarded as one of the most powerful Marvel characters among the likes of Doctor Strange and Charles Xavier.

Medusa — This Inhuman’s power is in her hair. She can control each strand of her mane, which is tougher than steel. She is also trying to bring Inhumans and ordinary humans together in the comics, and that seems to line up with Coulson’s ideals in “Agents of S.H.I.E.L.D.” Season 4.

Crystal — The elements are what Crystal controls. She can manipulate and animate earth, fire, air and water. Medusa’s little sister highlighted the choice some Inhumans have to get their powers. She didn’t want to expose her daughter Luna to Terrigen Mist early in life, but her husband, Quicksilver, forced Luna to get her powers early. While the ABC drama definitely can’t incorporate Quicksilver, choosing your destiny seems like a theme the show could explore in-depth.

Fans will have to tune in to “Marvel’s Agents of S.H.I.E.L.D.” Season 4 to see which classic Inhumans join the cast. Season 4 premieres Tuesday, Sept. 20, at 10 p.m. EDT on ABC.
