Soulmon

Soulmon is a Champion Level Ghost Digimon that looks like a Bakemon with a witch's hat. It is a Bakemon that has taken in the data of a witch that was entered through fantasy and it is assisted by a black hat that raises its magical power. Due to this, the curse and magic attacks it uses are immense to fulfill its appetite, as their cast magic drains the victim's life.

Marcus and the others ignored Agumon's warnings as Soulmon's pranks on Marcus happened more frequently and started to get dangerous.
