Pokémon evolutions by various conditions

This is a list of Pokémon that evolve by some kind of status or condition, such as gender, location or time of day. Once the condition is met, the Pokémon needs to level up once more in order to evolve.

This information applies to any games that feature both Pokémon from the chain, so for example in Generations 1-3 the evolution chain with Mamoswine doesn't exist.
