List of notable case characters

This is a list of minor characters in Detective Conan whose one time appearance in a manga case or episode made a notable impact on the plot of the main storyline or influenced the main characters in some way. This list excludes main characters, main law enforcement, the canon Black Organization, and mystery people related to the arc (e.g. Eisuke or Araide).

Sometimes characters on this list may have other minor background appearances, but those appearances generally aren't significant to consider them as recurring characters. Characters who have made multiple appearances in the manga are listed on minor recurring manga characters and those who have reoccurred in the anime or movies are listed on minor recurring anime characters
