Chi-Yu

Chi-Yu, also known as Iiyui, is a dual-type Dark/Fire Legendary Pokémon introduced in Generation IX of the Pokémon series. It is a member of the "Treasures of Ruin" and does not evolve. Chi-Yu resembles a goldfish, with its eyes formed by two pairs of curved jade beads, once considered sacred and used in religious rituals. Its body is composed of deep red and yellow flames that burn at over 3,000 degrees Celsius, capable of melting rock and sand. Chi-Yu's true form is the jade beads themselves, brought to life by the envy of those who desired them, while its body is a form it constructs using fire control. As a member of the Treasures of Ruin, it possesses immense power and unique abilities, including the move Ruination and the ability Beads of Ruin. Its design is often associated with the Chinese mythological creature Hùndùn and goldfish, with its name possibly derived from "crucian carp" and "jade."
