Anthony D. "Tony" DiNozzo, Junior, (or "Junior" by his father, Anthony DiNozzo Senior or Very Special Agent Anthony DiNozzo) was the Senior Field Agent on the NCIS Major Case Response Team led by Leroy Jethro Gibbs with Tony also serving as the second-in-command of the team and in rare occasions where Gibbs was usually absent or elsewhere, Tony automatically became the temporary leader of the team. After being with NCIS for fifteen years, having first joined the agency in 2001, Tony resigned from NCIS for good in May 2016 to care for his daughter, Tali David-DiNozzo with his position of Senior Field Agent being passed onto fellow NCIS agent Timothy McGee.
He is also the son of Anthony DiNozzo Senior and an unnamed woman as well as the partner/lover of fellow former NCIS Special Agent Ziva David.
Born in an unknown state, presumably New York, DiNozzo was the son of wealthy businessman Anthony DiNozzo Senior and an unnamed woman (whose maiden name was Paddington), with the family residing in Long Island, New York and also harboring some wealth although the degree of wealth they had was never revealed.
At the age of five, young DiNozzo endured nightmares about vampires due to his mother going through a phase involving Louis XV that inspired the decor of his room.
During his childhood, DiNozzo also owned some Sea Monkeys until his mother accidentally drank them, having confused their sea castles with her mint julep.
Due to the fact that his father was a Civil War re-enactor, young Tony was forced to carry the poop bucket during scenes, causing the other re-enactors to call Tony "their little poo boy".
DiNozzo's mother loved movies and used to take him to the theatre with her to watch movies, with DiNozzo later telling Ziva that she was the person who got him interested in movies. "The Little Prince" was the last movie they saw before his mother's death.
DiNozzo's mother died when he was only 8 and this triggered DiNozzo's own miserable childhood as his father struggles to look after him on his own and he was left behind in a hotel room on his own for several days at one point.
DiNozzo Senior would later remarry, choosing various women who would become young Tony's stepmothers with Tony having no positive or pleasant memories of any of them.
At some point, DiNozzo as a teenager was shipped off to boarding school. He attended six boarding schools in the four years he spent in high schools, making a habit of getting expelled from each one. The seventh and last one was Remington Military Academy, a private boarding school in Tiverton, Rhode Island. Tony completed his 12th grade year there, graduating high school in 1989.
Tony then attended Ohio State University, graduating with a Bachelor of Arts degree in Physical Education.
During his time at Ohio State, he was on the varsity basketball team and made it to the Final Four before losing to UCLA. He later participated in a football game leading a team against one from Michigan that was led by Doctor Brad Pitt who appeared in SWAK (episode). Tony broke his leg during the game which was revealed to have been broken by Brad himself.
At some point, Tony joined the Ohio State Alpha Chi Delta fraternity. He also received a combined score of 950 on his SATs.
While in Ohio State, Tony saw a townhouse on fire and rushed inside, finding a young boy inside a closet.
As Tony carried the boy out of the building, the boy mentioned his sister, Amber and as Tony attempted to save Amber, a part of the ceiling fell in front of him and as such, Tony decided to leave Amber and save the boy instead.
It was later revealed that Tony had a choice: save the boy or risk their lives to save Amber. Tony ultimately choosing to flee the building with the boy in tow.
Upon becoming a Detective, Tony spent two years in Peoria and Philadelphia before moving to Baltimore which was revealed in the Season 1 episode, High Seas (episode).
While at Baltimore, Tony ran into his future boss: Leroy Jethro Gibbs and the two sides worked together on a money laundering case.
Tony eventually discovered that his partner, Danny Price was a dirty cop which ultimately prompted Tony to resign from Baltimore PD for good and join NCIS instead, Gibbs having suggested it to him earlier.
Tony eventually joined NCIS and presumably began as an NCIS Probationary Agent before eventually being promoted to the rank of Senior Special Agent of the team.
JAG Season 8
Tony made his debut appearance in the JAG Season 8/NCIS backdoor pilot episode, Ice Queen (episode) where at the time of his introduction, he was the Senior Special Agent of the main NCIS Major Case Response Team led by NCIS Special Agent Leroy Jethro Gibbs which also included Agent Vivian Blackadder, Dr. Donald Mallard and Forensic Scientist Abigail Sciuto.
He was first seen driving to Potomac Park in the NCIS Major Case Response Team Truck.

Prior to joining NCIS, Tony did police work in Peoria, Illinois, Philadelphia, Pennsylvania, and Balitmore, Maryland. He was still working with Baltimore when he met Leroy Jethro Gibbs for the first time, catching up to the older man in a footrace while Gibbs was undercover. After learning that his partner on the Baltimore police force was "dirty" in 2001, Tony resigned and applied to work with NCIS instead.
Presumably, after a few months, Tony was promoted from Probationary Agent to NCIS Special Agent before becoming Senior Special Agent of the main NCIS team, a rank he held up until his resignation from the team in May 2016.
He has discribed himself as "the wild card."
Tony is a tall, lean man in his late forties with brown hair and green eyes.
As an NCIS Special Agent and also the Senior Agent of the Major Case Response Team, Tony was one of the most skilled Agents associated with NCIS in general.
He was trained to process crime scenes and interrogate any possible suspects too.
He was also extremely skilled in undercover work as evident by former NCIS Director Jenny Shepard choosing him for an undercover operation that lasted for most of NCIS Season 4.
Like Gibbs, DiNozzo was old school in terms of using traditional methods to solve a case but in recent years, DiNozzo had also begun using technology as well.
Like all NCIS Special Agents, Tony was trained in the use of a firearm with his primary weapon being a SIG-Sauer P228.
He was also a skilled marksman, capable of wounding and/or killing or non-lethally wounding a suspect as the situation required.
Regarded as his speciality, DiNozzo was exceptionally skilled in undercover work. It was this that eventually led him to taking on numerous alias during various undercover operations for NCIS.
He even worked with NCIS Director Jennifer Shepard on an undercover mission to help apprehend Rene Benoit AKA "La Grenouille".
Anthony DiNozzo Senior
Mrs. DiNozzo nee Paddington, first name unknown, was Anthony DiNozzo Senior's first wife and the mother of Anthony DiNozzo Junior. She was either British or was closely related to people from Britain as Tony has multiple British relatives.
She used to take her son on weekend trips to these dollar matinees in New York City. There was a pretty run down theater over on 42nd Street where she used to take Tony. She loved movies, and it is a passion she shares with her son.
The last movie mother and son saw together before she died was 'The Little Prince'. Tony was 8 at the time, meaning she died in either late 1978 or early in 1979.
Mrs. DiNozzo's best friend, sorority sister, and brides maid at her wedding to DiNozzo Senior was Linda Turner. Linda was also Tony Junior's godmother.
In S11's Dressed to Kill it was revealed that Linda's husband, Hamilton, had died the year before, and the two of them had then rekindled their friendship. Which had led to them dating and then getting engaged. While initially against the wedding, Tony gave his blessing at the end of the episode.
Vincenzo was mentioned in Head Case (episode), where Tony told Ziva his uncle owns a butcher shop on Long Island.
