List of Appearances

Anthony "Tony" D. DiNozzo Jr., (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.

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.



Born in an unknown state, presumably New York, DiNozzo was the son of wealthy businessman Anthony DiNozzo Senior and an unnamed woman 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".

Presumably at some point, DiNozzo's mother who may have been an alcoholic like her husband subsequently died and this triggered DiNozzo's own miserable childhood as he was left behind in a hotel room 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.

After finishing either boarding school or high school, DiNozzo then attended Rhode Island Military Academy.

He later 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 Brad Pitt. Tony broke his leg during the game which was revealed to have been broken by Brad alone.

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.


Tony in a flashback from the Season 9 episode, "Rekindled".

While in Ohio State, Tony saw a townhouse on fire and rushed inside, finding a young boy inside a closest.

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.

The young boy, still resenting Tony for refusing to save his sister later grew up and also got a job at the Baltimore Arson Unit and didn't meet Tony until the Season 9 episode, Rekindled (episode) and as such, this event was what later prompted Tony to become a Detective.

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, a position he held until his resignation and subsequent departure from the team in May 2016.

JAG Season 8Edit

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 also helped process the crime scene at Protomac Park where the remains of JAG Lieutenant Loren Singer were discovered.

While Gibbs and Viv headed to JAG to interview Singer's colleagues, Tony went out to find where Singer had fallen into the river and eventually drowned which he did.

NCIS Season 9Edit

In Nature of the Beast (episode), the Season 9 premiere episode, it was revealed that Tony had tasked with following Agent Simon Cade who newly appointed SECNAV Clayton Jarvis believed had committed treason.

However, it was also discovered that Sean Latham, a supposed friend of Jarvis's was the true traitor, having manipulated Jarvis into believing that Cade was guilty.

NCIS Season 10Edit

NCIS Season 11Edit

In Past, Present, and Future (episode), after learning that Ziva had gone into hiding, Tony personally headed to Israel in the hope of tracking Ziva down.

After months of searching which also saw Tony growing a beard as well, Tony later used all the clues he had gathered from Ziva's pattern and eventually tracked her down at the country house where she had been born and attempted to have her return to the United States with him but despite his best efforts, Ziva ultimately chose to stay behind in Israel.

In Once a Crook (episode), as a result of Ziva's abrupt and permanent departure from the team as well as NCIS itself with her ultimately choosing to stay in Israel rather than return to the United States, Tony, became insomniac which saw him not sleeping for the last days, as he struggled to cope without her.

This in turn ultimately hampered Tony's own ability to focus on the case concerning an informant of his who Tony had met while working as a cop in Baltimore and also the current investigation concerning the murder of Navy Petty Officer First Class Andrew Wells.

NCIS: New Orleans Season 1Edit

DiNozzo appeared in the NCIS: New Orleans Season 1 episode, "Carrier" where he was sent to New Orleans to assist the NCIS New Orleans Team led by NCIS Special Agent Dwayne Cassius Pride into a possible outbreak of bubonic plague on board the Navy Ship, the U.S.S. Geronimo which had resulted in the death of Navy Lieutenant Lewis Collier.

Upon arriving in New Orleans, DiNozzo arrived at the Geronimo and met Pride as well as Navy Commander Louanne Bates, the X.O. of the Geronimo with the three later wearing protective gear and searching Collier's quarters and later the quarters of Lieutenant Duncan for any kind of evidence as into where the plague had first occurred, the team having discovered Duncan in his bunk, dead from the effects of the plague. A search later turned up various evidence with the three later uncovering a water rat although tests that CDC officer Carol Wilson conducted revealed that the rat was healthy and like the Biological Attack on NCIS that had happened ten years previously, the plague itself had been created in a lab.

Presumably, after assisting the team, DiNozzo returned to D.C.

NCIS Season 12 Edit

NCIS: Los Angeles Season 7Edit

Tony appeared in the NCIS: Los Angeles Season 7 episode, "Blame It On Rio" where he worked with the NCIS Office of Special Projects Team to help track down a fugitive that Tony himself had been tasked with bringing back to D.C.

During this case, Tony also met the OSP team in person and also presumably for the first time, making him the fourth person next to Gibbs, McGee and Vance to have met or spoken to members of OSP in person while DiNozzo also became the third person behind Abby and Vance to gain personal access to the Office of Special Projects Headquarters.

NCIS Season 13Edit

In the Season 13 premiere episode, Stop the Bleeding (episode), Tony struggled to come to terms with Gibbs being shot but despite his urge to stay, was ordered by Vance to continue investigating the case.

Tony and CIA officer Joanna Teague, the mother of deceased NCIS Special Agent Ned Dorneget both traveled to Shanghai, China to dismantle the Calling once and for all.

While there, Tony shot dead the Calling's leader, Daniel Budd.

With the breakdown of his relationship with Zoe Keates, Tony spent an increasing amount of time searching for a sense of belonging and family, leading Gibbs to question whether Tony wanted to be an agent anymore.

As the team investigation into an escaped British spy, Jacob Scott, suggests evidence that Scott could next be looking to find Ziva, Tony becomes determined to find her before anyone can hurt her. He is shocked and worried when he sees evidence of Ziva's house in Israel burning in the aftermath of a mortar attack, and decides to fly out to find her. However, before he leaves his apartment, Abby and McGee arrive to reveal the fact that Ziva has in fact died. This leaves Tony completely devastated and manic in grief.

The following day, Tony is shocked to discover that he and Ziva have a daughter, Tali David-DiNozzo, due to the fact that Ziva never contacted him after he had left Israel. He questions whether Ziva ever really knew him, and if due to the fact that Ziva never told him of Tali's existence, Tali actually knows him. Despite this, he admits to McGee that he was in love with Ziva.

After he finds a picture of him and Ziva in Tali's bag, and Tali identifies the pair of them as her parents in Hebrew, Tony realises that Ziva must have told their daughter about him.

Although he was spending time with his daughter, Tony was also determined to be a part of the team that brings down Kort. When he arrives at the location McGee gives him once NCIS has tracked him down, he tells Kort that Ziva was his family, and fires along with the rest of the NCIS team when Kort goes to pull out his gun, killing Kort.

Later, Tony reveals to Gibbs that he is going to resign from NCIS in order to devote his time taking care of Tali, with plans to go to Israel 'to get answers', and then to Paris, due to the fact that Ziva loves the city. He then goes on to say goodbye to his friends at NCIS, before leaving.


Prior to joining NCIS, Tony worked as a Police Detective in Peoria and Philadelphia as well as Baltimore but upon discovering that his Baltimore partner was in fact corrupt, Tony chose to resign from the Baltimore Police Department force for good and join NCIS instead which occurred in 2001.

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.




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.

Undercover Edit

Tony's specialty was going undercover and he was so skilled at it that Gibbs regarded Tony as a "born operator".

This skill which had been honed to perfection enabled Tony to go undercover many times, especially if it required getting information about a suspect or person of interest in a case that the team were investigating without tipping off the suspects themselves, examples are in the Season 1 episode, Split Decision (episode) where he posed as a rogue weapons-dealer, unknowingly uncovering an Alcohol, Tobacco and Firearms operation in the process and in the Season 2 episode, Chained (episode) where while disguised as a prisoner, Tony befriended an escaped convict named Jeffrey White who had information on stolen Iraqi antiques.

His undercover skills were so good that Director Jenny Shepard chose him to help her with a top-secret undercover operation concerning her personal enemy, the Frog.

Languages Edit

Tony was fluent in Spanish and Italian.

While in Shanghai, China, he also displayed some fluency in Mandarin Chinese.

Firearms Edit

Like all NCIS Special Agents, Tony was trained in the use of a firearm with his primary weapon of choice being a SIG-Sauer P228.

Interrogation Edit

Tony was skilled at interrogating various suspects that the NCIS team come across. He was always seen interrogating suspects usually by himself or alongside Gibbs, McGee, Ziva and Bishop.

Lockpicking Edit

Tony was skilled in lock-picking.

Relationships with Family MembersEdit

Mrs. DiNozzoEdit

Various StepmothersEdit

Relationships with WomenEdit

Wendy MillerEdit

Amanda ReedEdit

During the case investigating the murder of his colleague, fellow NCIS Special Agent Chris Pacci, Tony met and subsequently befriended Amanda Reed with the two beginning a relationship.

Unfortunately, any hopes for a good relationship were permanently extinguished when Tony learnt that Reed was in fact Lieutenant Commander Hamilton Voss and also the one responsible for killing Pacci which left Tony stunned.

Upon being discovered, Reed attempted to escape but Gibbs cornered and shot her dead, avenging Pacci.


For a time, Tony dated a social worker named Michelle.

The relationship ended, prompting Michelle to break into Tony's apartment and fill his closet with dog crap.

Pam KimEdit

Zoe KeatesEdit

NCIS ColleaguesEdit

Leroy Jethro GibbsEdit

Abigail "Abby" SciutoEdit

Vivian "Viv" BlackadderEdit


Viv and Tony in the JAG Season 8/NCIS backdoor pilot episode, "Ice Queen".

At the time she joined NCIS, Viv who was also Tony's partner was still struggling to come to terms with the murder of her brother, Rex.

In the field, the two worked well together and had a sibling relationship although like Gibbs, Tony was left concerned by Viv's constant need for revenge against the terrorist who had carried out the USS Cole bombing.

It's presumed that after Viv blew the anti-terror operation in Rota, Spain, Tony stopped speaking to her for good and also subsequently cut off any kind of communication with her as well, presumably because he was angry at her for knowingly jeopardizing the operation or putting Gibbs's life in danger or maybe because he felt she was too far gone to be reasoned with.
