As you know from the season 3 finale of Marvel's Agents of S.H.I.E.L.D., Phil Coulson (Clark Gregg) is no longer the Director of S.H.I.E.L.D., becoming a regular agent once again and pairing up with Mack (Henry Simmons). O'Mara will take the reins, though we still don't know his character's name.
"It's a manly name," O'Mara teased to TV Line. "Yes, a very manly name."
We can also expect O'Mara to have a different approach than Coulson's. "It's definitely a new dynamic that we added to the mix," co-showrunner Maurissa Tancharoen said. "Things have been shaken up a bit."
O'Mara is an Irish actor whose past work includes In Justice, Life on Mars, Terra Nova, Vegas, and Complications, as well as a recurring role on The Good Wife. He is also the voice of Batman in the current DC Animation movie universe, voicing the caped crusader in Son of Batman, Batman vs. Robin, Batman: Bad Blood, Justice League: War, Justice League: Throne of Atlantis, Justice League vs. Teen Titans, and the upcoming Justice League Dark.
In light of the Sokovia Accords, and with Hydra obliterated, S.H.I.E.L.D. has been legitimatized again and no longer needs to operate in the shadows. Since the world presumes that Coulson (Clark Gregg) is dead, the organization needed a new Director (Jason O'Mara) to be the face of the organization. Coulson finds himself back in the role as an agent and teamed with Mack (Henry Simmons), and together they are tasked with tracking down and confirming the presence of Enhanced people, aka Inhumans. They have been trying to track down and capture Daisy (Chloe Bennet), aka 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. Agent May (Ming-Na Wen) is tasked with training specialist strike teams, and Fitz (Iain De Caestecker) and Simmons (Elizabeth Henstridge) have taken a big step forward in their relationship. But with Simmons' new promotion as Special Advisor to the Director in Science and Technology, Fitz, as well as her former team members, finds it hard to confide in or trust her since she's now the Director's confidant.
Robbie Reyes (Gabriel Luna) will roar into the lives of Agent Coulson and the team as a junkyard mechanic who can turn on a dime into the terrifying Ghost Rider. Will Robbie be a friend or foe to S.H.I.E.L.D. – as well as the world, itself? Meanwhile, Fitz discovers that socially awkward genius and friend Dr. Radcliffe (John Hannah) has started putting the finishing touches on a new, secret invention.
Marvel's Agents of S.H.I.E.L.D. returns Tuesday, September 20 in its new timeslot, 10:00 PM ET on the ABC Television Network.
