- Not to be confused with getting ninja'ed.
A Ninja is a role or role modifier such that the Ninja will never be seen as targeting anyone by a Tracker, Watcher, or other investigative role along these lines. It has been likened to the Tracker/Watcher equivalent to Godfather.
Although nothing technically prevents Ninjas from being town-aligned, and the modifier could even be useful for a Cop or similar role to prevent the Mafia discovering that they were investigated, the modifier is generally only seen in the hands of anti-town players, for whom it is a lot more powerful.
Use and Power
There will almost never be any ill effects to sending a Ninja to perform the Mafia's kill, so as long as the Ninja is alive, Trackers and Watchers will simply never see the Mafia kill. This tremendously decreases the effectiveness of both roles, as they can no longer directly catch scum.
