Digimon Story Time Stranger Omnimon Alter-S Field Guide

Omnimon Alter-S Overview (In-Game Profile)
A new form of Omnimon, born from a fusion between the WarGreymon subspecies BlitzGreymon and the MetalGarurumon subspecies CresGarurumon. Omnimon Alter-S is a different being from the Omnimon affiliated with the Royal Knights, but the multi-capable performance combining the special abilities of two Digimon remains the same, as does its strength.
How the pair came to fuse is a mystery. Did someone will it into being? Or does this fusion exist solely because of someone’s wish? The truth of the matter is unclear.

Omnimon Alter-S 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.
Omnimon Alter-S can de-digivolve into the following forms:
