Tony Dinozzo, full name Anthony Dinozzo is the womanising, chauvanistic agent on NCIS. Comes from a wealthy family and has a love for fast cars. He is very false in his opinions of women and prefers the blonde, busty type. He is rather unpleasant to Special Agent McGee, giving him the nickname of "Probie". He was infected with Bubonic Plague at the end of series 2, and someone tried to frame him for murder in series 3. Tries to make a pass often at new agent Ziva David much like he did with agent Todd, but is constantly blown off. Often recieves a slap across the back of the head from Gibbs.
Tony Dinozzo is played by Michael Weatherly who has also starred in many other US shows, such as Charmed, and has one son, August Weatherly, with his ex wife.
