Kimball Cho

He is a very serious and stoic person, literally, probably from his time in the army.
He is very willing to follow Jane's investigations and follow Lisbon, almost reluctant to follow anyone other than Lisbon or Jane.
He is always chosen as the lead agent when Lisbon has to leave, he is highly respected by the CBI team, showing concern and a desire to help when Jane is going through difficulties.
He generally appears to be the calmest and most lucid agent, but he becomes irascible if someone he cares about is threatened.

He is a member of the CBI team, along with Teresa Lisbon, Patrick Jane, Wayne Rigsby, and Grace Van Pelt.
Although he is usually a very serious person who always follows the case to the letter, he also has a very sharp sense of humor. He primarily acts as an interrogator, as he is very persuasive and an excellent listener.
He is a good friend of Rigsby, and his deadpan humor and calm demeanor complement and contrast with Rigsby's carefree character.

He is 37 years old, his last name is Cho, he hates pineapple on pizza, and he is 1.80 m tall.

Cho was a member of the Avon Park Playboys gang; his gang name was "Ice Man." After spending time in a juvenile detention center, he apparently found the right path and joined the United States Army.
