Necrozma

Necrozma is a Psychic-type Legendary Pokémon introduced in Generation VII, specifically in the games Pokémon Ultra Sun and Ultra Moon. Known as the Prism Pokémon, Necrozma is an Ultra Beast that originates from Ultra Space and is distinguished by its crystalline, black body. Its lore describes it as a being that was once whole and radiated light, but after an ancient incident, it lost its original form and now constantly seeks light to regain its power and stability. Necrozma is depicted as a powerful and often aggressive entity, driven by its insatiable need to absorb light, which it uses as its energy source. In the games, it plays a pivotal role in the storyline, eventually fusing with Solgaleo or Lunala to become Dusk Mane Necrozma or Dawn Wings Necrozma, and ultimately achieving its true, radiant form as Ultra Necrozma. Its existence is deeply tied to the concepts of light and darkness, and its design reflects its fractured, crystalline nature. Its unique origin and immense power make it a significant figure in the Pokémon universe, representing a profound force from another dimension.
