Digimon Story Time Stranger BigMamemon Field Guide

BigMamemon Overview (In-Game Profile)
A Mutant Digimon that acts as the boss of the Mamemon and is sometimes referred to as the “Smiley Bomber”. Some believe that BigMamemon is actually an aggregation of Mamemon.
Though normal Mamemon are about the same size as In-Training Digimon, they pack more power into their small frames than appearances would imply. BigMamemon, on the other hand, lives up to its name by being dozens, if not hundreds, of times larger than its smaller kin. At this size, why it’s still referred to as “Mamemon”, named for its small statue, is unclear.
BigMamemon has a warm, gentle personality and isn’t fond of conflict or battle. It can always be found playing with its Mamemon followers.
Its special move, Big Smiley Bomber, uses the Mamemon under its command as weapons. BigMamemon is said to shrink in size after using this technique.

BigMamemon Digivolution
Digivolution is the process that allows your Digimon to grow stronger and unlock new forms. Each Digivolution path has specific requirements, such as reaching a certain level, achieving a minimum stat threshold, or meeting personality and bond conditions.
Some Digimon also require special items or story progression to evolve. Choosing when and how to Digivolve is essential, since certain evolutions may branch into multiple options, giving you flexibility in shaping your partner’s role in battle.
De-Digivolution
In Digimon Story Time Stranger, de-digivolution allows you to return a Digimon to a previous form. Unlike standard digivolution, which requires stat thresholds and level milestones, de-digivolution has its own conditions. To de-digivolve a Digimon, one of the following requirements must be met:
- Encounter requirement: The Target Digimon must have already been encountered at least once during your playthrough.
- Personality requirement: The Target Digimon’s base Personality must match the current Digimon’s Personality.
Meeting either condition will unlock the option to de-digivolve, giving you more flexibility in reshaping your team and experimenting with different evolutionary paths.
BigMamemon can de-digivolve into the following forms:
