Main and supporting characters Special agents and intelligence officers Charles Irving "Chuck" Bartowski (Zachary Levi), the protagonist of the series, begins the series as an affable and anxious Nerd Herd associate at Buy More who unwittingly downloads the entire CIA/NSA secret database subliminally into his brain through an e-mail from old friend/nemesis Bryce Larkin, and must use his newly found knowledge to help the CIA and NSA in spy missions. He sometimes goes by the self-chosen alias and codename "Charles Carmichael." In "Chuck Versus the Final Exam" he passes his final spy test, and by "Chuck Versus the American Hero" he has been officially inducted into the CIA, although he was fired after going rogue in "Chuck Versus the Cliffhanger." He, alongside his new wife Sarah, choose to form a freelance spy company in the aftermath of the episode.

Little is known about her family, except that her father is a conman who was arrested during her teens. She is quite protective of her past. She is fired by the CIA alongside Chuck after his rogue operation in "Chuck Versus the Cliffhanger," but decides to form a freelance spy company with her new husband. First seen in: Chuck Versus the Intersect (Pilot) Colonel John Casey (Adam Baldwin) is an NSA agent, and is one of the agents assigned to guard the Intersect. Casey is promoted from Major to Colonel in "Chuck Versus the Colonel". He is dismissed for treason in "Chuck Versus the Tic Tac", but reinstated after his capture of the Ring director in "Chuck Versus the Other Guy".

First seen in: Chuck Versus the Helicopter CIA Agent Bryce Larkin (Matthew Bomer) was Chuck's college roommate at Stanford. He joined the CIA in 2002, his and Chuck's junior year, then learned that the CIA intended to take Chuck on as an operative, as tests had shown that his brain was capable of processing a staggering amount of visual information. Fearing that working for the CIA would destroy his good-hearted friend, Bryce manufactured evidence that Chuck had cheated on the test, thus removing him from the CIA's recruitment list. Five years later, Bryce sent Chuck the Intersect because he knew that Chuck had the mental capacity to interpret it. Bryce is killed in "Chuck Versus the Ring" attempting to destroy the Intersect 2.0 . First seen in: Chuck Versus the Intersect (Pilot) CIA Agent Daniel Shaw (Brandon Routh) is a CIA officer assigned to assume command of Operation Bartowski during their pursuit of The Ring.

First seen in: Chuck Versus Operation Awesome CIA Director Langston Graham (Tony Todd) was a supervisory agent at the CIA. He recruited Sarah Walker after her father's arrest. He had seen Sarah's birth certificate and is thus is the only other recurring character presumed to have known her real name. He acted as Sarah's supervisor on her mission to protect Chuck.

In "Chuck Versus the Ring: Part II" a video recording left by Stephen after his death reveals that he has been waging a secret spy war and that everything he's done has been "for her." Mary's whereabouts are currently unknown, even to Stephen. However it has been revealed that her disappearance was actually the result of capture, and that for an undetermined period of time she was a hostage of Volkoff Industries.
