Boldore is a blue rock-like Pokémon with an array of red crystals on its back and front, and a spine protruding from between its yellow ears. Rocky chunks at its sides comprise pincer-like limbs, tipped with red crystals similar to the ones on its back. Its orange crystal is the hardened form of its endlessly leaking energy. The crystal shines brightly when its power rises. It searches for underground wells in the caves where it lives.
