Pokémon can change themselves or be born or created with particular differences from the norm of the species. There are a number of Pokémon variations by type (not necessarily by Type), some of them from canon and others are Suocéverse-specific.

In general Variations are categorized in two scales:

• Whether the change is transient (will “run out” by itself or can be dispelled), or persistent (long-term lasting up to definitive for the specimen's lifetime).
• Whether the change is individual (selects and applies to only a limited / countable set of individuals) or general (applies over a population).
