Peralta is a cop that has never had to work that hard or follow the rules too closely. Perhaps because he has the best arrest record among his colleagues, he's been enabled - if not indulged - throughout his entire career. That is, until the precinct gets a new commanding officer, Captain Raymond Holt, who reminds this hotshot cop to respect the badge.
Jake is an Ashkenazi Jewish male with dark brown hair and brown eyes.
He is often seen wearing a button-down plaid shirt, a hoodie, jeans and at times, a stylish, black leather jacket. At Captain Holt's request, Jake has taken to sometimes wearing a tie. He used to wear a watch on his left wrist in the earlier episodes, his police badge on a chain around his neck and starting from the Season 5 Finale a wedding ring on his left finger.
Jake is a very competent detective with an incredibly immature, yet charming personality. He often butts heads with authority and teases his partner, and later wife, Amy Santiago. He has trouble expressing his emotions, preferring to crack jokes, but always shares his feeling eventually. He is extremely intelligent and calculating, but his intelligence is more focused on humour than his work.
He is a very laid-back individual, and takes his job seriously but likes the arresting-bad-guys part the most. Jake clashes with Captain Holt because of the latter's practical, down-to-earth methods against Jake's wisecracking nature. Jake Peralta has abandonment issues, given that his father left him at an extremely young age.
Jake was born sometime between May 21 and June 20, 1981, in New York City. He is a Jewish New Yorker, raised by his mother after his dad walked out on them when Jake was only seven years old.
As a child, Jake was the shortstop on his little league team. His dad was the coach, and after every game would take the team to Sal's Pizza. Halfway through their last season, Roger Peralta left his wife and son.
In Halloween, it is revealed that Jake has an Uncle Bob who taught him to shoot chess and backgammon pieces with a BB gun.
When he was 13, Jake had a crush on Jenny Gildenhorn. They attended his Bar Mitzvah together, where she broke up with him in favour of Eddie Fung. Since then, Jake has continued to hold onto hope that he and Jenny would reunite. He claims that Jenny dumping him is his worst breakup of all time.
After that, he lost his virginity to the daughter of one of his teachers, Mrs Stratton.
Rosa Diaz and Jake were classmates in the police academy. They bonded over their hatred of the training drills. Later, as detectives, they made a pact to trust each other fully when one offered to do 1,000 push-ups if proven wrong.
Jake has been working at the 99th Precinct for at least 8 years prior to the first season of the show. Before Raymond Holt took over as captain at the Nine-Nine, Jake enjoyed that Captain McGintley would allow him to get away with anything while on the job. He took advantage of McGintley's lax attitude and would participate in games with his coworkers, including The Jimmy Jab Games.
