Genesis Supernova is a Psychic-type move with 185 power and 100% accuracy. This special move was introduced in Generation VII and is exclusive to Mew when it is holding the Mewnium Z and uses the Z-Move upgrade of its move Psychic. Aside from dealing massive damage, Genesis Supernova also creates a Psychic Terrain for five turns, which boosts the power of Psychic-type moves by 50% and prevents priority moves from being used. This makes it not only a powerful offensive option but also a strategic move for controlling the battle environment.
