Digitamamon is a Perfect Digimon that is mostly in an eggshell except for his dinosaur-like legs and golden eyes. He can withdraw into his egg for protection and appears to have a near infinite space within his shell. He can control nightmare energy and release it from his eggshell. His name comes from "tamago", the Japanese word for egg, as a "Digi-Egg" called a "Digitama" from Japanese.
