Daley Wong is a highly skilled deputy inspector for the A.D. Police and Leon McNichol's partner. He is also openly homosexual. Daley flirts openly with the heterosexual Leon whenever Leon's temper tends to get the better of him, and Leon often reciprocates with good humor, creating a good working relationship. Daley's sense of humor is very dry and understated.
Daley is not developed much in the series. He is, however, portrayed to be loyal and highly competent, both as Leon's underling and as a commander in his own right (in the first and final episodes he is shown commanding his own AD Police squad).
