Leroy Jethro Gibbs
Special Agent Leroy Jethro Gibbs is a fictional Chief investigator from the NCIS television series by CBS Television, portrayed by Mark Harmon.
An experienced former US Marine Gunnery Seargant, Agent Gibbs is a highly skilled investigator and interrogator endowed with infallible intuition. He uses these skills to his advantage while working on a case. He also tends to think out of the command structure if that helps him.
Gibbs tends to be reticent, and reluctant to reveal his feelings. Only Ducky (Dr. Mallard) gets to call him "Jethro" on a regular basis, which suggests they have worked/known each other for a considerable time and there is a heightened sense of trust on both sides.
He is mostly called "Gibbs" by colleagues, "boss" by Tony and McGee. He is called "Gunny" by former USMC associates. He has been married three times to red haired women - all three marriages ended badly. One ex-wife stalks him on the anniversary of their split, another attacked him with a golf club and the other attacked him with a baseball bat. The mysterious red-headed woman who appears briefly to drop him off or pick him up at the end of a case (mostly S1) is never identified.
Gibbs can be extremely charming in an understated way and has a wicked sense of humour. He is unforgiving of his or his colleagues mistakes and demands high standards of himself and his team.
He has a coffee addiction and even has a personal rule about it:"Rule 23 = never drink a Marine's coffee".
Gibbs is fond of Abby and regularly bribes her with her favourite "Caf-Pow" beverage. He is aware Caitlin Todd has a crush on him, but never brings it up and isn't above lock-picking his team's desk drawers to see what they are "about".
He is building a boat in his basement by hand; with no power tools. This just leaves the question; how is he going to get it out of there?
Gibbs is pretty much useless with technology: he either can't or won't work a Palm pilot, and regularly trashes his mobile phones. Jethro needs corrective glasses for long sightedness, but is too vain to wear them. He can communicate in ASL with Abby but is out of step with popular culture "Why would Abby go to a fat party?".
A complex man of mystery and intrigue.
