PrinceMamemon is a Mutant Digimon whose name and design are derived from "Prince Mamemon", though it is also a pun on the musician, Prince. Having taken in data on the Net concerning a royal family, it is a prince of the Mamemon world. Partnering with KingEtemon, it plays the part of a mock royal family of the Digital World, and that's why it looks so gorgeous. Although its personality isn't awful, it was incited by KingEtemon and is convinced that it truly is a member of the royal family, and the embarrassing thing is that it considers even the "Royal Knights" to be its subordinates. Despite its appearance, the part that it boasts is its tremendous destructive power, since it is a Mega, after all.
