Night Baron (闇の男爵 Naito Baron?) is a fictional character that Yusaku Kudo invented in his bestselling mystery series.


Night Baron is a phantom thief who also occasionally descends to murder, but still has yet to be caught. The identity of Night Baron is currently unknown even to Shinichi. There are at least eight books in the series.[1] As little else is known about Yusaku's novels, Night Baron has no known nemeses or rivals. Night Baron's costume has been used multiple times to hide the identity of characters during a case. Additionally, Night Baron's name was appropriated for the name of a computer virus, which has been used by the Black Organization to protect sensitive data.


Night Baron wears a white face mask with eye-slits and a mouth curved in a twisted grin. The only visible physical features are that he is tall and thin, with straight black hair that falls just past his ears. He always wears a dark blue or black top hat, suit, and caped overcoat.

He seems very similar to Kaito Kid, but is willing to kill to avoid being captured.

The reward for the one who correctly deduces the sponsor's identity is that their stay at the hotel is free, as well as a copy of the mysterious Night Baron virus program. A costume of Night Baron is used three times. The first time, "Night Baron" pushes Conan off a high balcony into the hotel pool.
