Agent Grant Ward is deadly, precise and cool under fire. He's just doesn't play well with others due to his not-so-great people skills. He's volatile, but a decent guy with morals whose charm will eventually come through.

Soulful and quiet, Agent Althea Rice (a.k.a. "The Cavalry") is an ace pilot, weapons expert and soldier who is a bit damaged from her combat experience and has gone beyond the call of duty.

Finally, there's Agent Leo Fitz and Agent Jemma Simmons, also known as "Fitz-Simmons" as the two spend all their time together. Think more along the lines of a brother and sister who always bicker and annoy one another. They came up together and are masters in their fields: Fitz is good with weapons and gadgets while Simmons is into science. Yes, they are huge nerds (and also attractive).
