Almost immediately after ABC announced that Joss Whedon’s new TV series would be based on S.H.I.E.L.D., everyone began to theorize who would show up in the series. Now that casting will be ramping up for the show, we know at least who the core characters will be and they’re all original creations.

TVLine got their hands on the casting information, and posted these descriptions:

SKYE | This late-20s woman sounds like a dream: fun, smart, caring and confident – with an ability to get the upper hand by using her wit and charm.

AGENT GRANT WARD | Quite the physical specimen and “cool under fire,” he sometimes botches interpersonal relations. He’s a quiet one with a bit of a temper, but he’s the kind of guy that grows on you.

AGENT ALTHEA RICE | Also known as “The Calvary,” this hard-core soldier has crazy skills when it comes to weapons and being a pilot. But her experiences have left her very quiet and a little damaged.

AGENT LEO FITZ and AGENT JEMMA SIMMONS | These two came through training together and still choose to spend most of their time in each other’s company. Their sibling-like relationship is reinforced by their shared nerd tendencies – she deals with biology and chemistry, he’s a whiz at the technical side of weaponry.

Not much more to say as we just have to wait until the pilot arrives to judge for ourselves, but in Whedon we trust.
