Also known as "Pete," Peter was born on July 5,1960 the second child of Mike Brady and the late Sarah Brady, who became Carol's stepson when she wed Dad Mike in The Brady Bunch TV series' pilot episode. He is the third oldest of the Brady Family. Peter is the middle Brady son and is very close to his brothers Greg and Bobby. He loves to joke around with Marcia and Jan and is very protective of Cindy.
He has a fragile ego that manifests itself in extremes; often he lets his achievements go to his head while at the same time lets the little things get him down. He celebrates his rescuing of a little girl from a falling shelf of toys, calling himself a hero, but not long after decides he has no personality when some kid at a party says he's dull.
The clumsiest of the bunch, he sometimes gets overexcited and acts impulsively before thinking. Peter is anything but dull. He may not be too great at fixing bikes or making ice-cream sundaes, but he builds a mean model volcano. He's also great detective and a pretty good reporter. Peter even proves himself to be a fine actor by playing Benedict Arnold in the school play, a role he later lives to regret. </span>Nevertheless, he is a fun-loving boy whom girls adored later in the original series. He has a non-related twin named Arthur Owens (also played by Christopher Knight), who is shown in the episode "Two Pete’s in a Pod" which had the plot of Peter having two dates at the same time. Peter is also the only one in the family with brown eyes - all the others had blue or green eyes.
Peter later joined the military for career guidance, as seen in NBC-TV's The Brady Girls Get Married. In later sequels, he is an administrative assistant (at one point, working under his fiancée, Valerie; they later end their engagement), and still later, a business partner with Bobby. Peter was the only Brady child to not have a spouse or significant other when The Bradys was cancelled. A little later, after sister Cindy married David Johnson, Peter came to Monticello, where David talked him into joining the county sheriff's department as a deputy under Sheriff Pat Moriarity; he later ran for the office of sheriff after Moriarity retired,and won! And one last thing: while still a deputy, he married a police detective named Chris, and adopter her nine year old son!
