Necrozma Gx

Necrozma is a Psychic-type Legendary Pokémon introduced in Generation VII, specifically in the Pokémon Ultra Sun and Ultra Moon games. Hailing from Ultra Space, Necrozma is known as the "Prism Pokémon" due to its ability to absorb light, which it uses as an energy source. Its natural state is often depicted as a dark, crystalline entity, but when it absorbs enough light, it can transform into more radiant and powerful forms, such as Dusk Mane Necrozma (fused with Solgaleo) and Dawn Wings Necrozma (fused with Lunala), and ultimately into Ultra Necrozma. Necrozma is unique in its classification as a Legendary Pokémon that can fuse with other Legendaries, a mechanic central to the plot of its debut games. Its behavior is driven by an insatiable hunger for light, leading it to sometimes act aggressively in its pursuit of energy. In the anime, Necrozma plays a significant role in the Pokémon the Series: Sun & Moon arc, where its story of light absorption and subsequent suffering is explored. It represents themes of light, darkness, and the pursuit of power, making it a compelling figure in the Pokémon universe. Its unique design and lore have cemented its place as a fan-favorite Legendary.
