Contessa Valentina Allegra de la Fontaine: Eliza Dushku (01 of14)
Open Image ModalJessica Jones: Amy Acker(02 of14)
Open Image ModalDum-Dum Dugan: Neal McDonough(03 of14)
Open Image ModalNorman Osborn: Alan Tudyk(04 of14)
Open Image ModalNo self-respecting comic-book story can function without a bad guy, and Osborn/the Green Goblin certainly qualifies. No character did more to damage S.H.I.E.L.D., which means he could be the basis for a season-long arc (or three), and Tudyk proved in "Dollhouse" that he can play scary, damaged characters very well. Obviously he's got a commitment to ABC's "Suburgatory," but if he's underused again in the upcoming season, we say set him free! (credit:Getty)
Jimmy Woo: Ken Watanabe(05 of14)
Open Image ModalThis Asian-American secret agent would work well within the context of a weekly spy-adventure series, and ever since Watanabe reminded us in "Inception" of what a charismatic actor he is, we've wanted to see a lot more of him on our screens. Delving into the "life model decoy" stories that Woo was involved in would also allow Whedon and the writers to explore the kind of identity issues seen in the short-lived Fox drama "Dollhouse."

Daisy Johnson: Amber Benson (06 of14)
Open Image ModalJohnson, who in the comics is Director of S.H.I.E.L.D., has the ability to cause seismic activity and once defeated Magneto that way. It's been too long since Benson had a prominent role on television, and the role of Daisy would draw on her strength, range and general ability to kick ass. (credit:Getty)
Jessica Drew: Summer Glau(07 of14)
Open Image ModalGlau, who debuted as a dancer in the "Buffy" spinoff "Angel" before blowing our minds on "Firefly," has the right kind of physicality and grace for the role of Jessica Drew, the original Spider-Woman. After a series of adventures fighting a wide array of bad guys, Drew eventually became a private investigator, meaning she (possibly in combination with a similar character, Jessica Jones) could potentially anchor a weekly drama with procedural overtones.

Carol Danvers: Evan Rachel Wood(08 of14)
Open Image ModalWood proved her dramatic chops at a young age thanks to her breakthrough role in "Thirteen," and after showcasing her kick-ass side in "True Blood," we think there are few young actresses that could pull off Carol Danvers' combination of poise and empowerment as well as she could. In the comics, Major Carol Danvers (AKA Ms. Marvel) has served as executive director of S.H.I.E.L.D. after Nick Fury was deposed, and is a superheroine in her own right after an explosion caused her genetic structure to meld with Captain Marvel's, imbuing her with superhuman strength and flight. Since we're betting ABC doesn't have the budget for a super-powered superhero show, we see Danvers as a respected agent of S.H.I.E.L.D. with aspirations towards leadership. (credit:Getty Images)
Sharon Carter: Tricia Helfer(09 of14)
Open Image ModalAs an integral part of S.H.I.E.L.D. and the occasional girlfriend of Captain America, Carter would be a key part of any TV spinoff, and Helfer proved on "Battlestar Galactica" and in countless guest roles that she has the presence, acting chops and physical ability to play the part of an active field agent with a complicated past. It'd be nice if Hayley Atwell, who played Sharon's aunt Peggy in the "Captain America" movie, wanted to play her own niece in the American drama, but that seems unlikely. Either actress would be a fine addition to the new show, but we'll admit that even the hint of a "BSG"/"Avengers" crossover makes us all tingly. (credit:Getty)

Open Image ModalAgent Coulson: Clark Gregg(14 of14)
Open Image ModalClark Gregg's Agent Coulson has been an integral part of the Marvel cinematic universe since his introduction in "Iron Man," and is so beloved by fans that he was retroactively brought into the comics. We still don't know if "S.H.I.E.L.D." will be a prequel or sequel to the events of the "Avengers" movie, but whether Coulson is revealed to be alive, a LMD, or Whedon suddenly introduces Phil's long-lost twin brother Bill, we need to see Clark Gregg in "S.H.I.E.L.D." in some capacity if the show goes to series.
