Necrozma

Necrozma is a Psychic-type Legendary Pokémon known for its ability to absorb light and emit a dazzling glow. It has a crystalline, angular body with a black, prismatic appearance. Necrozma can transform into different forms, such as Dusk Mane and Dawn Wings, when it fuses with Solgaleo or Lunala, respectively. In its Ultra form, it becomes Ultra Necrozma, a powerful Dragon/Psychic-type with enhanced abilities. Necrozma is associated with the concept of light and darkness, often depicted as a being that seeks to restore its lost light.
