―Terry Jeffords in "The Oolong Slayer"
Lieutenant Terrence “Terry” Vincent Jeffords is a main character of the show. He is a linebacker of a man who's lost his nerve, not because he's a wimp, but because a year prior to the series, his wife Sharon had twin baby girls; Cagney and Lacey, and he can't imagine not seeing them grow up.
Terry had a rough childhood. He was overweight, was bullied, and had a cruel father. He had a joy in his early life, though: the books of D.C. Parlov. He viewed police officers as superheroes, which is why he joined the force, and was saved from bullies by one.
During his time as a field officer, his infamous nickname was "The Ebony Falcon". He has a third daughter called Ava who was born later on Thanksgiving 2015 after Sharon Jeffords goes into labor at the 99th Precinct.
He played linebacker at Syracuse.
Terry spent a year abroad in Tokyo in his junior year at college, where he briefly dated Chiaki, who broke his heart.
He doesn't get along very well with her brother-in-law Zeke, due to how badly Zeke treats him. The only time Zeke showed respect for Terry was out of sympathy when Zeke thought Holt was abusing his authority.
He had an addiction to food which got real bad, to the point where he broke a restaurant window because they were closed at 6:00. He got over it by re-booting his system (sticking his head in ice water) every time he felt for a food craving.
Before joining the 99th Precinct, he was a detective at the 65th precinct. There, he was mocked after he exclaimed that a cat was an accomplice to a burglary, and was helping a seemingly paralyzed (he was faking his disability) man, who turned out to be the burglar when Terry and Jake went back to the case twenty years later.
And prior to the show's events, he worked at the 18th precinct with Captain Holt, as a fat version of himself nicknamed as "Terry Titties." In 1995, he made Detective and started his first day at the 65th Precinct.
Terry is usually seen at his desk in a normal shirt, usually with a tie and suspenders. He is 6'3", and is 240 pounds. He is very muscular as he likes to work out whenever he can. Charles describes him as looking like 8 circles with suspenders.
During Chocolate Milk, Terry wants to have a vasectomy however he is prevented from doing so by his massive stature; the doctor didn't have enough anaesthesia for a man of his size.

Several episodes contain a running gag involving Terry Jeffords' love for yogurt.
‘’Read full article on Terry talking about himself in third person Terry often uses third person to describe his emotions.
In the earlier parts of the show, Terry repeatedly brought up his past obesity. This stopped in the later seasons, however, as it could've been seen as offensive.
Terry is caring, protective over the squad, and hardworking. He has a habit of referring to himself in the third person. When he had twin daughters, he freaked out and ended up afraid of getting himself hurt, but soon enough he showed himself to be a tough, heroic, fearsome man who would do anything to protect his squad. He fearlessly charged against an armed criminal to save Captain Holt's life, twice, and when Jake, Charles, and Gina were trapped in a store with terrorists breaking in, Terry defied orders in order to prevent them from being endangered - he openly defied Detective Pembroke to prevent him from endangering his friends. Holt sees potential in Terry to be a captain, and recognises him as a great leader and a compassionate person.
Terry is a good cop and a serious person, but he is also extremely smooth and everyone in his precinct really likes him - he is almost as much of a father figure to some detectives as Holt is. Terry often jumps at the chance to console or to otherwise help a detective in a personal situation, even if he doesn't understand such situations from personal experiences: he consoled Rosa after the departure of Adrian Pimento, and drank with Jake when he realized that them solving the unsolvable case was all about him getting over Amy.  He shows amazing amounts of tolerance with his fellow detectives: he can speak on reasonable terms with an enraged Rosa, a despondent Charles, and having to contend repeatedly with the incompetent Hitchcock and Scully.
Terry is capable of a ferocious temper, almost as ferocious as Rosa's (which is really saying something). He reacts furiously when Jake tries to exclude him from his first case back in the field, when the Vulture disregards the lives of his colleagues during a hostage situation, and when he is perceived as fat by some people. He is capable of incredible feats of strength when riled, such as ripping a thick book in half with both hands, slamming a door so hard that the window, and the interior of the room, completely falls apart, and even lifting the back end of a car off the ground with both hands for an extended amount of time.
Terry was the precinct's champion marksman.
