BigMamemon

BigMamemon is a Mutant Digimon whose name and design are derived from "Big Mamemon". It exists as the boss of Mamemon, which hold the alias of "Smiley Bomber", and it's questioned whether it isn't simply 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. The text on the soles of its shoes reads "BIG" and "MAME".
