Gabumon

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. Due to its extremely timid and shy personality, it always gathers up the data which Garurumon leaves behind, and shapes it into a fur pelt to wear. Because it is wearing the fur pelt of Garurumon, who is feared by other Digimon, it fills the role of safeguarding itself as a result of protecting its body. When it is wearing the fur pelt, its personality does a complete 180° shift.
