Some of that love for characters is because they have been well-developed and fleshed out, with compelling backstories and arcs, while for others, it was that they brought such interesting story opportunities to the show. However, no series on air for so long is perfect, including NCIS, having just wrapped season 22, so there are also occasions in which characters were underutilized or fell victim to wasted potential, which forever tarnished their time on the show. Unfortunately, the way to resolve it has often been killing them off, leaving them with unresolved or unfulfilling arcs.
10. Agent Michelle Lee
One of the most divisive characters in NCIS, Agent Lee joined the team between seasons 3 and 4 before being outed as the mole in NCIS season 6, killing two agents in the process. However, it was revealed that she was forced to work against the team after her sister Amanda was kidnapped. Ultimately, Michelle allowed Gibbs to shoot her dead to help the gang take down Weatherman, and she died a hero. Michelle was both a hero and a villain, and her complex and flawed character made her an interesting addition to the show, which is why it was a shame when her time ended. She certainly deserved better.
9. Ned Dornegat
Ned “Dorney” Dornegat was first introduced in season 9 as a probationary officer before working his way up to NCIS Cyber Operations. He had a fun relationship with DiNozzo, and a complex relationship with his mother, Joanna Teague. Dorney met his end in NCIS season 12, when he helped the MCRT track down a terrorist cell that was recruiting children. He died a hero, saving multiple people during a terror attack in Cairo, and was killed during an explosion. Dorney was a strong addition to the team, but a character who could have been developed better, and his abrupt ending killed that potential.
8. Emily Fornell
7. Mike Franks
A former Supervisory Special Agent, Mike Franks was a mentor to Gibbs, with the two having a strong connection. Brought out of retirement to help Shepard and Gibbs in season 3, Franks helped the MCRT bring down the Reynosa cartel. However, the fan favorite met his end in the NCIS season 8 episode “Swan Song” while going after the Port to Port Killer. Luckily, a younger version of the character appears in NCIS: Origins, exploring his backstory, but in NCIS, he was a character who deserved more.
6. Agent Brent Langer
5. Eli David
Eli David was the classic case of a character who was misguided. His single-minded obsession with defending Israel came at the expense of his children – radicalizing son Ari and endangering the life of daughter Ziva. He was eventually killed in a drive-by shooting by anti-peace operatives, but the character should have had a different fate. It would have been nice to see him fulfill his goals and patch things up with his kids, but his death in NCIS season 10 illustrated the dangerous nature of the world of NCIS.
4. Jackson Gibbs
3. Director Jenny Shepard
Despite being a divisive figure during her run on the show, Lauren Holly’s Director Jenny Shepard was a strong and interesting addition to the team. NCIS‘s first-ever female boss met her tragic demise when the ghosts of her past caught up with her. Following her involvement in the death of arms dealer La Grenouille, whom she wrongly believed had killed her father, Shepard was eventually murdered in a shootout with a hitman sent by long-time nemesis Svetlana Chernitskaya. Jenny left an enduring legacy, and could have been in the show so much longer.
2. Special Agent Paula Cassidy
Paula appears in the NCIS season 12 episode ‘The Lost Boys,’ as a hallucination.
1. Special Agent Caitlin “Kate” Todd
One of the most shocking deaths in the entire franchise, Caitlin was the first core character to be killed off on the show, dying in the NCIS season 2 finale “Twilight.” The Secret Service agent was assassinated mid-sentence by terrorist Ari Haswari, in the final few seconds of the episode, in one of the most heartbreaking scenes in the whole show. The character was killed off after actress Sasha Alexander’s decision to leave NCIS due to the rigorous schedule of network television.
