Officer Brennan almost always has a slightly confused look on his face. He has a bulbous nose and a rather long face.
He wears a blue shirt with a name-badge on one side and the official badge of the Arcadia Law Enforcement on the other, along with a tie, navy-blue trousers, and a navy-blue jacket with a star badge on one arm.
He is a slightly incompetent and gullible, but well-meaning officer who tries his best to help maintain law and order in Arcadia. He greatly likes his job and often tries to help people in need, like when he called for a police car to assist Claire and Toby, who he thought was severely ill.
Brennan is on good terms with friend and colleague, Detective Scott, and often assists him in solving cases and catching crooks.
