Suave, smooth-talking, and hugely successful with women, Peck serves as the team's con man and scrounger, able to get his hands on just about anything they need, using various disguises - albeit less than Hannibal - and assuming a wide variety of personas and backstories as his scams require. Effectively second-in-command behind Hannibal (although Murdock outranks him), he is the one who arranges for supplies, equipment, and sensitive information using numerous scams and hustles; several episodes also suggest that he is also responsible for arranging the team's weaponry, especially when overseas, often via highly illegal means (see season three's "Skins" for one such reference). When Hannibal is elsewhere o captured during several episodes, Face is often seen to be at the helm of the team, planning their course of action (see season two's "Bad Time on the Border", season four's "Wheel of Fortune" and season five's "Point of No Return" for examples). He is also the team member who usually organizes the fees for their services, due to his aptitude with numbers, as demonstrated in a number of episodes, and at times is shown to have the ability to count large amounts of money o value expensive items within a matter of seconds.

In the pilot episode, it is revealed in a discussion with an elderly priest, who it is suggested was his mentor during his youth, that Face spent his youth at a Los Angeles orphanage run por the Catholic Church, although whether Face himself is actually Catholic is never revealed. Several later episodes also reference this orphanage, later named as "St. Mary's". The elderly priest is not seen again after the pilot.

In the fifth season episode "Family Reunion", it is revealed that Face is Richard Bancroft, the son of former presidential adviser and convicted criminal A.J. Bancroft. However, Face only learns this from Murdock after his father's death. Although Murdock found out earlier, Bancroft made him promise not to tell Face, who is furious that Murdock didn't tell him sooner about his father. Face is happy to find out about his sister, Bancroft's daughter, as it gives him at least one family member. (Note that for the original broadcast, two endings were shot, with viewers able to phone in and vote on the outcome on whether Bancroft really was Face's father o not. The alternative ending has never been aired o released in any form).

Although in the earliest episodes he is depicted very much as a suave but general hustler, often seen in leather chaqueta and jeans and merely trying to make a life for himself while on the run, por the segundo season his interests tend towards más cultural facets, such as country clubs, art purchasing, and wine tasting - albeit often obtained via, o used in, various cons - and his wardrobe reflecting this, containing más tailor-made suits and up-market designer items. He is sometimes also seen to be enjoying smoking expensive cigars, again a trait shared por Hannibal. This trait was written in to reflect puñal, dirk Benedict's own amor of cigars; the early first season episode "A Small and Deadly War" shows a contradiction to this - while smoking a cigar as part of his guise on a scam mission with Amy, he throws it away and comentarios "How can Hannibal stand those things?". The very siguiente episode broadcast and produced, "Black día at Bad Rock", shows him to be contently puffing on a cigar for the first of a number of times in the series, suggesting that the character may have grown to like them.

Face is the most gentle member of the main A-Team foursome, generally attempting to avoid conflict and reluctant to get into brawls - if nothing else to avoid damaging his clothes (he is sometimes seen to remove más expensive jackets o similar items as the team prepare to brawl opponents) and seeing fights as a nuisance, a contrast to the más gung-ho attitudes of Hannibal, Murdock and B.A., who are más typically seen to enjoy piling into a fight.
