A theory exists that Cubone is the child of a dead Kangaskhan due to its similar appearance to it. GamesRadar's Carolyn Gudmundson supported this theory and thought that it was possible that some Pokémon species were mixed up and Kangaskhan was originally an evolution to Marowak. Missingno. and M are commonly believed to be the missing link between Cubone and Kangaskhans theory.
