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.

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.

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.

Biography

Pre-Series

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 theater 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 struggled to look after him on his own. At one point, he was left behind in a hotel room on his own for several days.

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.

DiNozzo was shipped off to boarding school when he was 11. 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. 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 18 months in Philadelphia before moving to Baltimore, where he stayed for almost two years. While at Baltimore, Tony ran into his future boss: Leroy Jethro Gibbs and the two worked together on a money laundering case. It is also revealed that Tony had proposed and was engaged to a woman named Wendy, during his time with the Baltimore PD.

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 joined NCIS and began as an NCIS Probationary Agent before eventually being promoted to the rank of Senior Special Agent of the team.

Occupation

Prior to joining NCIS, Tony did police work in Peoria, Illinois, Philadelphia, Pennsylvania, and Baltimore, 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, apart from a short period of 4 months when he was reassigned in season 6.

Personality

DiNozzo was often seen most times as immature and obnoxious, but funny. The rest of the team hates to admit it, but Tony's antics and pop-culture knowledge have led to solving quite a few a few cases, because of his creative ways. He tends to annoy his co-workers (especially his boss, Agent Gibbs), yet no one can deny he is a good cop, and they miss him when he is not around.

There also have been a few times where he's shown interests in more of his work than being funny. However he is shown to slacking a lot at work and needs to be told to work many times. He always mocks his co-workers and gives them nicknames. He is known throughout the seasons to be a ladies man and objectifies women to the annoyance of his female partners. He also have a wandering eye and it takes him a while before he figures out he wants a serious relationship and stop sleeping around.

He is very loyal and cares about his friends, he protects them and will put himself in harms way to save them.

Physical Appearance

Tony is a tall, lean man in his late forties with brown hair and green eyes.

Abilities

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. At one time, observing Tony interrogate a suspect, NCIS Director Leon Vance asked to Gibbs and Bishop, also watching behind the glass, "Has the Tony show started yet?" in a nod to the peculiar style of interrogation that is unique and compatible to DiNozzo's personality. Nevertheless, he is able to show great results when interrogating a suspect, despite his peculiar methods.

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. She also gave him the opportunity to lead his own NCIS team in Spain, but he passed on the promotion to stay with Gibbs and the team.

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.

Firearms

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.

Interrogation

He can be laid back when it comes to the situation and is blunt, however showed in Baltimore when he and Danny Price were interrogating Joey Peanuts. He is fairly laidback when it comes to interrogation and helped Joey by offering him a piece of gum and doesn't want to chew gum alone, however when the situation comes to getting louder just like in Bounce (episode), he got louder at Mitch Wilkins after how he wanted to know after Justin Grady was killed and the reason why he killed Justin Grady with the pictures on how Renny Grant and Carl Davis were framed as well as Justin Grady being killed with reference of The Three Stooges.

Lockpicking

Undercover Work

Regarded as his specialty, 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".

Family Members

Anthony DiNozzo Senior

Anthony Sr. and Anthony Jr. didn't always have the best relationship. When Tony young, he was sent to a boarding school by his father. As the years went by, Tony showed a lot of resentment to his father because of how his father behaved when Tony was growing up. Anthony Sr. would always flaunt about his money that he didn't have and then turn around and say that he would be having problems with his credit card so he didn't have to pay for a meal, hotel room, etc.

Mrs

Mrs. DiNozzo and Tony at a screening of 'The Little Prince'. (Shell Shock (Part 1))

Mrs. DiNozzo

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.

Various Stepmothers

Tony didn't really have relationships with his step-mothers because his father's marriages would usually be over with before it began.

Tali David-DiNozzo

Tali is the daughter of Tony and former NCIS agent and love interest Ziva David.

Vincenzo

Vincenzo was mentioned in Head Case (episode), where Tony told Ziva his uncle owns a butcher shop on Long Island.

Relationships with Women

Wendy Miller

He was dating Wendy when he was a cop in Baltimore. He proposed and they got engaged. Right before the wedding she broke up with him and he never new why. In season 9 he gets an invite to a christmas lunch by her, but he does not show. Later in the season she appears when she is close to a case, as she is a journalist. They start up again their flirty tone and clear the air. She reveals that she did really love him but wasn't ready to settle down.

Amanda Reed

Pam Kim

Dr. Jeanne Benoit

Tony's relationship with Dr. Jeanne Benoit was his most serious relationship prior to Ziva. He met Jeanne while undercover as Tony DiNardo, a professor at a local university. During the months he was undercover, Tony was investigating Jeanne Benoit's father René Benoit (a.k.a. La Grenouille, a.k.a. The Frog) and becoming closer to Jeanne. He began to develop serious feelings to her and eventually they began dating. As their relationship started to become more serious, Tony struggled with hiding the truth from her as he did not want to hurt her. Eventually, he was forced to admit the truth to her and later lied about ever having loved her in order to keep her distant from Tony and the truth about her father.

Zoe Keates

Erica Jane Barrett aka EJ

He briefly dated EJ in season 9. She was a fellow NCIS Special Agent who transferred in from Rota, Spain. Their relationship did not last long, but it appeared to be meaningful for the both of them.

Ziva David

During several intimate moments, the two came close to revealing how they felt, but held back most of the time as they did not want to ruin theirs and the team dynamic. They have kissed as a part of an undercover operation early on in their partnership, and people bought their act. They never had much screen time after becoming romantic, but in season 7 and in later seasons, hints were dropped about them getting closer even though it might not have been all the way. It is always clear that Tony found Ziva attractive, and Ziva one time admits that Tony is not bad looking as well. They might have stepped over the line in Jet Lag (episode) when they both confronts one another about lying about sleeping on the couch in a hotel room they shared, meaning they both slept in the bed. Their romance is slowburning and teasing for the whole series.

Relationships with NCIS Colleagues

Leroy Jethro Gibbs

The two are shown to have somewhat of a father-son relationship. While Tony has immense respect and admiration for Gibbs, he also fears him just as equally. Even during times when it seems like Gibbs is making strange or unreasonable plans, Tony will put his absolute faith and trust in his boss that things will work out right while also staying close to help him if needed. Because he knows Gibbs so well, Tony knows how Gibbs will react during certain situations, around certain people, and during certain topics of conversation. During moments of uncertainty, Tony will usually turn to Gibbs for his thoughts and insight.

Gibbs trusts Tony completely and is shown to appreciate him, even if he considers Tony to be mostly annoying. He believes that Tony is an important part of the team and has numerous times throughout the series praised his skills as an Agent to others. He is also shown to appreciate Tony's antics as he knows that they make the team more tightknit and gives them all a break from the mostly sad realities.

Ziva David

Tony and Ziva had a rough start when she started at NCIS. She was the half-sister of known terrorist and murderer Ari Haswari. Once Ziva became a member of the team, their relationship became easier and much friendlier. Tony often mocked her lack of American culture and slang but found an opponent in her when she would mock his love life and behavior. It is clear that the two cares deeply for each other and are concerned when things seems to bug the other. They often know when someone is bugging one another before anyone else does in the team.

During several intimate moments, the two came close to revealing how they felt, but held back most of the time as they did not want to ruin theirs and the team dynamic. When Ziva was thought to have been killed, Tony showed emotional torment over this but was relieved when she was discovered to have faked her death for the safety of their daughter. Ziva is also shown to be crushed when the team believed he was dead in season 5. it is also suspected that they shared a bed while on assignment in Paris, when both lied about taking the couch in the hotel, meaning both of them slept in the bed. They share a kiss good bye when Ziva leaves the team and after years apart they eventually, the two moved to Paris to raise their daughter Tali.

Timothy " Tim" McGee

Him and McGee both had a tough but brotherly relationship. Tony constantly mocks Tim on his "geek" lifestyle and interests but also acknowledges that he has strengths that Tony himself does not possess. While he continually teases Tim and calls him a variety of nicknames often played on the first part of his last name "Mc". Tony does not hide that he thinks Tim is a highly capable and trustworthy agent and left leadership of the team to Tim when he left NCIS.

Tim is mostly annoyed with Tony, but they are both loyal to each other. Tim mocks Tony back, though not as much, and he is mostly annoyed with his behaviour. He is especially annoyed with his constant movie references and the pranks Tony subject him to. He does however consider Tony to be a capable Agent and trusts him. He also cares about him and will often be worried and investigate if Tony seems to be quite.

Abigail "Abby" Sciuto

The two are shown to have a sibling like relationship. Like the team, Tony is very protective of Abby and often does not hesitate to rush to her aid when she needs it. Abby also cares deeply about him and has shown real concern for him during times he was in trouble. She loves his humour and often describes Tony as great to others. She is very physical with him, giving him hugs and kisses on the cheek. He most of the time calls her "Abs"

He also knows her quite well and can tell when she's upset as she will typically change small things, such as when she stops playing music when she's sad. He'll then show concern and help her in any way he can.

Eleanor "Ellie" Bishop

Dr. "Ducky" Mallard

Similar to Gibbs, the doctor and Tony have a father-son like relationship although their dynamic is more relaxed and fun. Tony fully trusts Ducky's findings but often tries to keep the doctor from ranting too long during his well-known stories.

Jennifer "Jenny" Shepard

Tony and Jenny Shepard's relationship grew closer after Gibbs temporarily left NCIS. She put Agent DiNozzo leader of the team and the two of them worked on a secret case for months without the team knowing. This case led him to go undercover as a favour to her as the case was personal. After Gibbs returned, she offered Tony his own team in Rota, Spain, but he turned it down because he wanted to stay with the team. This shows her belief in his skillset and capabilities. He was one of the agents that took Jenny's death especially hard, as he was on her protective detail along with Ziva when she died.

Stanley "Stan" Burley

Caitlin "Kate" Todd

Kate and Tony was partners for two whole seasons. They loved mocking each other and had a brother/sister relationship, where they both support each other when its needed and prank and gets annoyed with each other. She was espesicially annoyed with his behavior towards women and his player antics and his ignorance of her privacy. At the same time she things he is a good man and a capable Agent. Tony is shown to take her death hard.

Vivian "Viv" Blackadder
