Season two of "Agent Carter" will feature more ties to Marvel's shared universe, including some that stretch far beyond the comparatively grounded corner the ABC series resides in. Hayley Atwell's super spy will travel to Los Angeles for season two with Jarvis (James D'Arcy) in tow to investigate Isodyne Energy. There they'll go up against the Marvel Cinematic Universe's version of Madame Masque, a classic Iron Man villain brought to life by Wynn Everett. And, as revealed last year, the season will also include the extra-dimensional energy known as the Darkforce.

"Agent Carter's" showrunners Michele Fazekas and Tara Butters spoke with Comic Book Resources about the upcoming season and the Darkforce's role in the show -- and how it ties "Agent Carter" to the upcoming "Doctor Strange" film.

When asked if Isodyne Energy is connected to the Darkforce, Fazekas answered affirmatively. "Basically, Isodyne is a company that we invented based in part on real life companies like Radiodyne or General Atomic or the beginnings of the Jet Propulsion Lab -- all of which were in L.A. in the '40s, and were developing the space program and were developing nukes," explained Fazekas. "That's what Isodyne is, and what you'll learn is they were involved in the nuclear testing out in the desert when they were testing the, at the time they were calling it the atom bomb -- and one of these tests didn't go as expected. You'll learn more about that in Season 2, but they stumble upon what people in the Marvel Universe will know as Darkforce, but because they've never seen it before they just name it Zero Matter. That's our tie-in to the 'Doctor Strange' universe, and also to 'S.H.I.E.L.D.' because you've seen it in 'S.H.I.E.L.D.' as well."

The Darkforce played a part in "Agents of S.H.I.E.L.D.'s" first season, as it powered the antagonist Blackout in the episode "The Only Light in the Darkness." But just because the Darkforce powered that supervillain in a certain way in the present day Marvel Universe doesn't mean it will work the same way in the 1940s-set "Agent Carter."

"The cool thing about what we learned as we researched Darkforce over the course of Marvel comic book history is, it affects people in different ways," explained Fazekas. "It's created a bunch of superheroes, it's created a bunch of villains, and it has all these different properties. It could be a liquid, it could be a gas, it could be a solid, it could give you powers, it could kill you. It has a lot of different applications, which was cool for us. We were able to select what we liked and sort of make our own rules as to what it does, how it operates, and who it affects in our world."

"Agent Carter" returns with a two-hour premiere on Tuesday, January 19, at 9 pm ET/PT on ABC.
