ABC has released the latest look at "Marvel's Agents of S.H.I.E.L.D.," and is introducing viewers to the crime-fighting unit's dynamic duo behind all of the science.
Agent Leo Fitz (Iain De Caestecker) and Jemma Simmons (Elizabeth Henstridge) specialize in bio chemistry and technology, respectively.
"They have like a brother-sister relationship, SImmons is the bio chem and Fitz is the gadget team," Henstridge said. "Together, they're unstoppable."
The new series, which airs Tuesdays this fall, follows Agent Phil Coulson (Clark Gregg), who has assembled a select group of agents from the worldwide law-enforcement organization known as S.H.I.E.L.D. to investigate cases around the world and protect its citizens from extraordinary threats.
