Earlier this week, it was reported that "Terra Nova's" Jason O'Mara is joining the cast of "Agents of S.H.I.E.L.D." season 4 as the new boss of the covert organization. His character has been described as a character "whose Marvel roots go back to the 1940's."

Aside from O'Mara boarding the ABC series, another recent update on the upcoming series is the promotion of one team member, as revealed by the official synopsis for the next run:

"In light of the Sokovia Accords, and with Hydra obliterated, S.H.I.E.L.D. has been legitimized again and no longer needs to operate in the shadows. Since the world presumes that Coulson is dead, the organization needed a new Director to be the face of the organization."

It goes on, "Coulson finds himself back in the role as an agent and teamed with Mack, and together they are tasked with tracking down and confirming the presence of Enhanced people, a.k.a. Inhumans. They have been trying to track down and capture Daisy, a.k.a. Quake, who has gone rogue in an attempt to atone for sins from the past. But with the world believing that Daisy is a dangerous outlaw who has taken down banks and bridges, the new Director has no qualms about taking her down for good."

Based on the synopsis, Agent May will also be tasked to train strike teams, while Fitz and Simmons will take their relationship to the next level. Also, the new season will introduce a Ghost Rider, as announced last month at the Comic-Con.

"Agents of S.H.I.E.L.D." season 4 premieres on Sept. 20, 10:00 P.M. on ABC.
