Some old characters are 1. Special agent Kate Todd 2. Special agent Mike Franks 3. Director Jenny Shepard All these 3 characters died during the course of the various NCIS seasons
Ogio Kirby Mountainsmith I.T.Z
None. Gibbs and DiNozzo are the two characters who have been present in every single episode of NCIS that has aired till date.
The name of his character in NCIS Los Angeles is G Callen. His real name is Chris O'Donnell. He is the head of the NCIS team in Los Angeles and reports to Hetty. He is similar to the Gibbs character in original NCIS but isn't so senior to the other characters. So, he shares a friendly kind of rapport with other characters.
he is only a reoccurring cast member.

no names can be up to 64 characters in length.
There is a book series that started with NCIS but it is not the same characters from the show and in my opinion the books didn't read well, they were very boring and sounded more like a crime documentary.
