Tapirmon is an Animal Digimon. It is thought that it is a Digimon that was generated from a medical computer for detecting brain waves, and it seems that it uses the data from humans in REM sleep as nourishment. In recent studies, it has been proven that it has the power to purge particularly bad nightmares and malignant computer viruses. Also, since it has the ability to change the captured nightmares and viruses back to normal, it is considered a holy Digimon. It wears a Holy Ring on its foreleg. Its "Nightmare Syndrome" is the same technique as that of the Ultimate Digimon, Digitamamon, but its connection to Tapirmon is a mystery.
