An Evil King Digimon said to be sealed in the deepest parts of the Dark Area. Because of its immense power, Belphemon’s data has been put into Sleep Mode by the Digital World’s system. Due to this deep sleep it cannot attack directly, but its snores inflict damage, making Belphemon: Sleep Mode difficult to attack. Its special move Eternal Nightmare is unleashed through peaceful snoring, and it uses Lampranthus to shoot a black flame from the chains coiled around its body. Eternal Nightmare is recommended for those suffering from insomnia, as everlasting slumber is almost guaranteed.
