In anticipation of “Marvel’s Agents of SHIELD’s” premiere, a slew of new promotional material about the show’s central characters has appeared online. In addition to the above extended TV spot for the series, Entertainment Weekly debuted new character portraits that offer up an inside look into who each of these new Marvel Cinematic Universe characters are.

Chloe Bennet, for instance, plays a hacker named Skye. “Most hackers are portrayed as weird outcasts who only know how to deal with electronics. She’s a computer hacker who is not socially awkward. She’s just as much of an actress as I am, she knows how to get her way,” Bennet tells the outlet.

Then there’s Brett Dalton‘s Agent Grant Ward, who is a Black Ops specialist. “He’s a one-man ninja, he’s a Swiss Army knife, he has a tool for every situation,” Dalton says. “But he’s got a gap in that skill set and that’s anything involving other people.”

Ming-Na Wen plays Agent Melinda May, a pilot and weapons expert. “Something has happened to her at a level she couldn’t cope with so she ended up doing paperwork. She’s called in by Phil [Coulson] to join the team but she’s reluctant to get back on the field because of her deep dark past. Every human being needs to play a kick-a** character like this,” Wen says.

Agent Leo Fitz, played by Iain De Caestecker, is an expert in weapons technology. “He designs and builds all the gadgets and technology. He’s kind of lost touch with reality and spends a lot of time with Simmons — they can have the most crazy argument you’ve ever seen and then 10 minutes later it’s like nothing happened. He spends a lot of time living in front of the reality of a computer screen. Now he’s entering into this world that’s more hands on,” Caestecker says.

Fitz’s other half, bio-science expert Agent Jemma Simmons, is portrayed by Elizabeth Henstridge. “‘She’s always in the lab and works very closely with Fitz; like an old married couple. She’s highly intelligent doesn’t apologize for it and has come up the ranks very quickly,” she says.

Last but not least, there’s the man who came back from the dead: Clark Gregg‘s Agent Phil Coulson. “The last time I looked from this guy’s eyes they were going dark fast. And now he’s walking around with the story of this close call that he had and recovering from that,” Gregg says. “I don’t know how you can go through what Phil Coulson went through — and he doesn’t even know how near-death or full death that is — without being changed somehow. That’s not something that’s going to be ignored.”
