Ziva David, portrayed by Cote de Pablo, formerly held the post of Mossad Liaison Officer to NCIS, to which she was appointed following the
murder of Special Agent Caitlin Todd by a rogue Mossad operative named Ari Haswari. David was Ari's control officer and half-sister. After Agent Todd's death, she requested a liaison assignment to NCIS, where she subsequently joined Special Agent Leroy Jethro Gibbs' team. At the end of Season 6, Ziva falls under suspicion as a spy for the Mossad.
Her specialty with the Mossad was espionage,assassination and terrorismand is highly trained in the martial arts. She speaks Hebrew, English, Arabic, Spanish, French, Italian, German, Russian and Turkish. Despite being fluent in English, she sometimes misinterprets idioms and phrases that have different meanings in other languages if translated directly; this is a running joke within the series. Ziva is very skilled with a knife and has been shown teaching her colleagues how to throw it properly. She is the one person Gibbs trusts with any type of firearm in difficult, potentially hazardous, situations. In her career, she has traveled
extensively to countries including Egypt (where she met Jenny Shepard), Iraq, the United Kingdom and Morocco. In the episode "Good Cop, Bad Cop" Ziva became a probationary NCIS Special Agent after she terminated her links with Mossad for good. Since then, Tony has referred to her (as with McGee) as "Probie". As of "Rule Fifty-One", she is a citizen of the United States and able to become a full agent.
Ziva rarely speaks of her personal life. Her father Eli David is the director of Mossad. The show rarely mentions Ziva's mother, Rivka, who taught her to drive; all that is known is that she does not have the same mother as Ari. Her younger sister, Talia "Tali" David, was killed in a Hamas terrorist attack against Israel at the age of sixteen. She also has an Aunt Nettie who likes to play mahjong. Ziva's hobbies include playing the piano, singing, dancing (she took ballet when she was young), cooking,reading, and boxing. She enjoys the fictional drink Berry Mango Madness. She drives a red Mini Cooper, likes listening to the Israeli band Hadag Nachash and the Latin American band Kinky. She does not own a television but her favorite film is The Sound of Music.
De Pablo describes the character as someone who is "completely different from anyone else on the show" and that because "she's been around men all her life; she's used to men in authority. She's not afraid of men."
