Move/Core Series/Unique Moves

Some Pokémon have moves specific to themselves or their evolutionary line. These unique moves are known as signature moves. Some of these moves are powerful moves that only certain Legendary and Mythical Pokémon can learn, such as 's or 's Steam Eruption. Other moves serve to highlight game mechanics or create unusual effects. One example is 's, which allows it to possess almost every conceivable move.
