True Crime: Streets of LA/Gameplay

Character relationships
Why Nick first refused, and then accepted this case is personal; his father, Henry Wilson, was an exceptional police officer who was involved in a major drug operation in the 1970's; one day, he disappeared, and was never found. Soon afterwards, Internal Affairs found a stash of cocaine in his locker, bringing his motives and role in the situation into sharp question. Though heartbroken by his father's disappearance, Nick refuses to believe this.

Although branded as every police officer's worst nightmare, Nick Kang is secretly highly respected by a number of his peers. His relationship with Rosie begins extremely shakily, but develops into a firm bond based on mutual respect. On two occasions, Nick directly places himself in harm's way to protect the life of his partner.

Rosie learns the story of Nick's father, and that when he died, Nick and his brother Cary had traveled to Hong Kong to grieve. Nick then returned for revenge while solving another case. His methods grew increasingly reckless in his pursuit of "justice". FBI agent Masterton distrusts Nick Kang. Masterton wants him off the case, yet is unable to do anything because the Bureau has a contract with Wanda Parks. He grows even more frustrated as Nick embarrasses him with his sarcastic sense of humor.

Both Nick and his brother Cary are accomplished martial artists, but Nick makes a personal vow to himself to protect his younger brother from harm, because of what happened to their father. He is unable to keep him from being attacked by Rocky's thugs, though, and pursues him relentlessly (in a possible side story, Nick fails to protect his brother, leading to his death. Enraged, Nick vows to avenge him and singlemindedly goes after Rocky, losing sight of the truth).

Nick went under the surname "Kang" when his father Harry Wilson died, because he couldn't live up to or match his father's expectation and reputation as a great cop. He shares this feeling with George, his father's best friend.
