BigMamemon

BigMamemon is a Mutant Digimon. It exists as the boss of Mamemon. As a matter of fact, it's suggested that it is an aggregation of Mamemon. Since normal Mamemon are the same size as Rookie Digimon, they possess a degree of power that couldn't even be imagined from their appearance, but as its name suggests, BigMamemon is dozens or even hundreds of times the size of a Mamemon. However, the reason why a "Mamemon" is this size is still unclear. Its personality is extremely gentle, and it hates conflict and battle, so it is always playing with its Mamemon followers.[3]
