In the realm of crime procedurals, ex-spies are a familiar trope. However, NCIS distinguished itself by introducing an exceptional character in Ziva David, played by Cote de Pablo. Debuting in Season 3, Ziva quickly became one of the show’s most beloved characters. As a Mossad spy and assassin, she evolved into a formidable federal agent under the mentorship of Leroy Jethro Gibbs (Mark Harmon), the show’s iconic lead agent.
