Necrozma

Necrozma is a Legendary Pokémon introduced in Generation VII, appearing in Pokémon Sun, Moon, Ultra Sun, and Ultra Moon. It is classified as the Prism Pokémon and is of Psychic/Dragon type. Necrozma is known for its unique ability to absorb light and its crystalline, alien-like appearance. In the lore of the Alola region, Necrozma is said to have once been a being of pure light that fell to the world ages ago. It is believed to have powered the region before its light was stolen by two other legendary Pokémon, Solgaleo and Lunala.

Necrozma possesses the ability Prism Armor, which reduces the damage taken from super-effective attacks. Its signature move is Photon Geyser, a special Psychic-type attack. Necrozma has several alternate forms that can be achieved through fusion with Solgaleo or Lunala, or by absorbing their power. These forms are Dusk Mane Necrozma (fusion with Solgaleo), Dawn Wings Necrozma (fusion with Lunala), and Ultra Necrozma. Ultra Necrozma is its most powerful form, achieved when it has absorbed enough light and is in its Ultra form. This form is Psychic/Dragon type and gains the ability Neuroforce, which powers up super-effective attacks.

Necrozma's design is characterized by its sharp, geometric body, glowing eyes, and a head resembling a prism. Its alternate forms showcase significant changes, with Dusk Mane Necrozma appearing more quadrupedal and lion-like, while Dawn Wings Necrozma takes on a more bat-like and ethereal appearance. Ultra Necrozma boasts a more imposing and radiant form, embodying its restored power. It plays a central role in the story of Pokémon Ultra Sun and Ultra Moon, where the player intervenes to help restore its stolen light.
