Donphan

Donphan (Japanese: ドンファン Donfan) is a Ground-type Pokémon introduced in Generation II. It evolves from Phanpy starting at level 25. Donphan is a gray, elephant-like Pokémon with a thick, black band of hide running down the length of its back and extending to the tip of its long trunk, resembling a car tire. This tough hide prevents regular attacks from inflicting even a scratch. Male Donphan have longer tusks than females. Donphan has the ability to curl up into a ball and violently roll around like a wheel. These rolling tackles are strong enough to knock down a house. While normally calm, Donphan can become enraged and start a rampage. Donphan travels in herds with a ranking system. The larger its tusks, the higher its rank in the herd. Donphan's design is likely based on an elephant, with the tire-like markings referencing its rolling abilities. Its name, Donphan, is thought to be a combination of 'don' and 'elephant'.
