Get ready for the Marvel Cinematic Universe's Golden Age, because the 1940s-set "Agent Carter" is coming to ABC this fall! The series, starring Hayley Atwell's special agent Peggy Carter, will follow the sharp-shooter's life following the events of 2011's "Captain America: The First Avenger" and last year's "Agent Carter" Marvel One-Shot short film that appeared on the "Iron Man 3" Blu-ray.

Thanks to the new series' status as a period piece, the entire world of 1940s Marvel will finally be able to be mined for adaptation, meaning we might finally get to see more of characters whose stories have most likely ended in the modern MCU. Considering all of the Golden Age heroes either originally published way back in the '40s or inserted there thanks to later flashback stories, there are a lot of characters that could pop up in the show's opening credits. Here are the six characters we hope to see fighting alongside Agent Carter.

Howard Stark

The "Agent Carter" one-shot ends with Peggy getting plucked out of her misogynist and mundane surroundings by Tony Stark's dear old dad to help him start a little organization called S.H.I.E.L.D. Any series focusing on Agent Carter's efforts getting the super spy agency off the ground should include Howard Stark - no questions asked. Good news: Dominic Cooper, who portrayed Stark in both "Captain America: The First Avenger" and the "Agent Carter" short, is eager to grow the mustache again. It remains to be seen how regular duties on an American TV show would affect Cooper's film career, even if the actor is willing to make such a commitment, but any appearances he could make would be more than welcome, and they'd provide even more connective tissue to the MCU.

Dum Dum Dugan

Just like Howard Stark, ol' Dum Dum also appeared in the "Agent Carter" one-shot. Timothy Aloysius Cadwallander Dugan has come a long way since his debut in 1963's "Sgt. Fury and his Howling Commandos" #1; he's appeared consistently in comics ever since his debut and he's become one of the most iconic S.H.I.E.L.D. members of all time. So far, Neal McDonough hasn't reprised the role in any modern-day Marvel movie, which leads us to believe that Movie Dugan hasn't discovered the secret to long life that's kept his comic book counterpart going all this time. No problem! Just make him a regular on "Agent Carter" so classic Cap fans can get their Dum Dum fix! Unlike Dominic Cooper, McDonough's no stranger to television. He's used to the grind thanks to roles on "Justified" and "Desperate Housewives."

Gabe Jones

Dum Dum isn't the only Howling Commando we want to see in "Agent Carter." Gabe Jones, played by Derek Luke in "Captain America: The First Avenger," would be a welcome addition to the new show. According to "Agent Carter's" summary, the show will tackle the sexism of 1946 America head-on, and we think it'd be smart for the show to champion the efforts made by African Americans as well as women during World War II. Like Dum Dum Dugan, Jones has gone on to become synonymous with S.H.I.E.L.D. - and we've only seen him once! Gabe Jones' story should be told, and "Agent Carter" should make that happen. Plus, putting any of the Howling Commandos -- whether it's Dum Dum, Gabe or others -- in the cast connects the show to "Agents of S.H.I.E.L.D.," where Agent "grandson of a Howling Commando" Triplett's been kicking ass lately.

Betsy Ross

As the Golden Age version of the hero appropriately named Golden Girl, Betsy Ross has numerous ties to the Marvel Universe that could be explored to rich effect on "Agent Carter." As a member of both the FBI and Women's Auxiliary Army Corps during the 1940s, Ross seems like she would have a lot in common with Peggy Carter. In the comics, she took on the name Golden Girl and wore a bulletproof cape while serving as Captain America's sidekick. If her last name sounds familiar, that's because she's since been retconned into being General Thaddeus "Thunderbolt" Ross' aunt, a fact that would help further tie "The Incredible Hulk" into the larger MCU.

The Falsworth Siblings

He's a gay man that's basically Britain's equivalent of Captain America and she's a take-charge heroine with vampire powers. There are no two characters more ready to be embraced by the Internet than Brian and Jacqueline Falsworth. As Union Jack and Spitfire, this brother and sister combo would add some international flair to "Agent Carter" and provide the show with a super hero twist; his super strength and her super speed can easily be accomplished on the small screen. And with Victoria Hand having exited "Agents of S.H.I.E.L.D." before coming out to the viewing audience, the MCU desperately needs its first gay hero. Let it be Union Jack.
