* Because of how the stat calculations work due to their base stats, the following Pokémon cannot have Protosynthesis boost the following stat in battle without stat changes taking place. This accounts for with a negative Nature and 0 individual and effort values applied to the stat that will be higher by default and a positive Nature, 31 individual values, and maximum effort values applied to the stat that cannot be increased.
