Columbo

Columbo is a seemingly bumbling but actually highly astute homicide detective. He is known for his unkempt appearance, often seen in a rumpled trench coat, and his unassuming demeanor, which belies a sharp mind for solving complex crimes. Columbo has a knack for lulling suspects into a false sense of security, leading them to underestimate him at their peril.

Personality-wise, he is polite, rarely displaying anger or irritation, and often expresses admiration for the intelligence and achievements of the people he investigates, which further disarms them. Despite his casual, almost disheveled look, there's a keen intelligence and a methodical approach to his work. He is famous for his catchphrase, "Just one more thing," which he uses to circle back to a conversation when he seemingly remembers a crucial detail, often catching suspects off guard.

Columbo is often seen arriving at crime scenes in his old car, engaging with suspects in a conversational manner that seems aimless but is actually quite purposeful. He has a unique way of investigating, focusing on inconsistencies in the stories of suspects and piecing together what really happened through observation and conversation rather than relying solely on forensic evidence.
