Diancie is a small, vaguely humanoid Pokémon with a distinctive design. Its lower half is a cone-shaped gray rock topped with a large pink diamond, while its upper body resembles a white dress with small mitten-like hands. A golden half-circlet adorns its neck, centered with another pink diamond. Its gray head features purple eyes with red sclerae, pointed ears, and an elaborate headdress of pink crystals—four spikes along the top, hanging side crystals, and a prominent circular centerpiece on its forehead studded with a small golden piece and pink diamond.
Diancie originates from a mysterious mutation and can instantly create diamonds by compressing atmospheric carbon. These diamonds serve as both weapon and defense, typically unleashed in devastating storms. The Pokémon is widely considered one of the world's most beautiful creatures, its shimmering pink body celebrated as an extraordinary sight. It inhabits underground cave networks like the Diamond Domain, a crystal kingdom where it reigns as queen over numerous Carbink—though it largely ignores their presence. Diancie can communicate through telepathy, as shown in the movie Diancie and the Cocoon of Destruction.
When Diancie Mega Evolves, its transformation is dramatic. The white dress lengthens and loses its sleeves while the lower body becomes solid pink crystal, surrounded by an elaborate arrangement of longer crystals extending down the back. The neck circlet gains outward-curving tips and gains a companion waist circlet. Its headdress centerpiece becomes heart-shaped, with additional hanging crystals sprouting from the sides and back—one back diamond now rounded with two smaller gems below it that trail ribbon-like structures. The head diamond alone exceeds 2,000 carats.
Mega Diancie's power surges dramatically. It can now forge diamond swords during combat and shines so brilliantly when light reflects off its purified surface that looking directly at it becomes impossible. Fans often refer to this form as the "Royal Pink Princess" due to its appearance. Its combination of beauty and battle prowess makes it remarkably adaptable in any situation.
