Category Monsters is a term coined by Raiburuto to define monsters that have a characteristic in place of "Effect" that appears in that monster's classification, e.g. the Union in "[Machine/Union]". Toon, Spirit, Union, Gemini, Tuner, and Timeshifted Monsters are all Category Monsters. Fusion, Ritual, Synchro and Xyz are not Category Monsters. The term "Category Monster" is used with certain Extract Monsters and their support.
