Gholdengo

Gholdengo is a lively, cheerful, friendly Pokémon that evolves from Gimmighoul. Its shiny, sturdy, durable, golden body is made up of 1000 densely packed stacked gold coins, which it controls for both offensive and defensive purposes: it overwhelms its enemies by firing coin after coin at them from anywhere on its body in quick succession, and it can absorb impacts and lessen the damage it takes by letting coins fly off from areas hit by enemies. It gets along well with others and is quick to make friends with anybody.

It is associated with the number 1000, a grand milestone.
