The Monster Rancher video game and anime franchise features monsters raised by monster breeders, who then fight in tournaments against other monster breeders. Each of these monsters are uniquely defined by a primary breed (such as Golem), which defines its basic form and abilities, and a sub-breed, which defines its color scheme, modifies appearance, and slightly alters some of its statistical capabilities. Breed is commonly specified as Primary/Sub because of the inconsistency of name and form for the generated monsters between the games. For example, Golem/Suezo indicates a monster with primary breed Golem, sub-breed Suezo, and manifests as a large humanoid figure with the bright yellow skin and single eye that are characteristic of the Suezo monster breed. Each monster breed also has at least one "rare" sub-breed. These often unusual sub-breeds cannot be created by combining. They only come from certain CDs.
