Ninja is a LEGO theme based around the Samurai and Ninjas of feudal Japan. It ran from 1998 to 1999, with additional figures created for the Mini Heroes Collection one year later, in 2000. It is frequently considered to be a subtheme of Castle, as the traditional European-style medieval sets were discontinued the year prior, and the Ninja packaging sports the same shade of orange as the Castle boxes throughout the 1990s. Ninja accessories were also included in 10066 Castle Accessories released i
