Mummymon is a Ghost Digimon. Its whole body is wrapped in bandages in the manner of an Egyptian mummy. It is also known as the "Necromancer" due to its summoning and manipulation of the reluctant souls (residual data) of annihilated Digimon. What it's thinking is difficult to understand because it is taciturn and its facial expressions are concealed, but it is a dangerous being that, if attacked, will brandish its weapon and completely beat down the opponent, and, if cornered, will start randomly firing its cherished gun, "Obelisk".
- Snake Bandage: Coils the bandages on both of its arms around the opponent, like a snake.
- Necrophobia: Summons ghosts to drive its opponent into maddened death.
