List of Appearances

Anthony "Tony" D. 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.



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 sometime in the mid-to-late 1980s.

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 was also in the Ohio State Alpha Chi Delta class of 1989. 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.


Witty and arrogant, egotistical and charming, intelligent and overbearing, Tony's complicated personality was only surpassed by his skill and ability as a federal investigator. As far back as his teenage years, Tony was athletic and confident, often masking any fears or insecurities behind a vain exterior. He disliked talking about his own past, in part due to a difficult childhood, but enjoyed being the center of attention and proving himself right. This overbearing nature sometimes complicated investigations, making others find him abrasive, but Tony consistently redeemed himself on the job with his ability to consistently produce results. Even into his 40's, Tony remained defiantly boyish and immature, making jokes, movie references, and playing pranks that others often considered beneath a man of his age.

Tony was most charming with women, and had a long string of relationships and one-night-stands over the years, preferring to avoid commitment until he unexpectedly became a father. Tony's approach sometimes struck others as sexist, but he was able to work with female colleagues and superiors with no hint of resentment or annoyance as to their gender. Tony's liking for films and the arts would sometimes come out with flair, such as when he made a show of informing his coworkers that he had bought a suit from Sy Devore because they had also sold suits to Frank Sinatra.

Coming to terms with his past and with people he had given loyalty, friendship and trust to was often difficult for Tony; he remained angry at his father for neglecting him as a boy until he was in his 40's, and the two men, proud and touchy, found it difficult to reconcile at first. His lack of a father figure in childhood led him to look up to Leroy Jethro Gibbs as one, a status Gibbs honored behind his gruff persona. Tony valued loyalty highly and hated betrayers and liars; his career at NCIS started in part because Tony found out his partner in the Baltimore, Maryland police was "dirty", leading him to quit.


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 a skilled marksman, capable of wounding and/or killing as the situation required.


Tony was a skilled interrogator, often interviewing suspects and witnesses at the crime scene (which ocasionally irritated his boss, Special Agent Gibbs, as DiNozzo was much more fond of flirting with female witnesses).


Tony was skilled in lock-picking.

Timothy "Tim" McGee

Already a veteran agent by the time Tim McGee joined NCIS, Tony often supervised the new agent and relished calling him "Probie" during his probationary first year of service. McGee, in turn, took his new-guy status and various assigned tasks in stride. Tony maintained some of this air of superiority and fondness for teasing McGee throughout some ten years of working together, but was surprised on various occasions by the wit and cleverness that McGee hid behind a rather bland exterior. Upon his departure from NCIS in Season 13, Tony symbolically passed on one of his favorite titles for himself, addressing McGee as "Very Special Agent McGee."
