Question: what is gabumon based on?
Answer: Gabumon is a Reptile Digimon whose name and design are derived from the "Gabu Kashira" (がぶ頭?), a Kabuki puppet whose face instantly changes from that of a timid maiden to a horned fiend with the pull of a string. Although it is covered by a fur pelt, it is still clearly a Reptile Digimon.
