Ponyta

Ponyta (ポニータ Ponyta) is a -type Pokémon, and can evolve into Rapidash starting at level 40.

Appearance
Ponyta is a horse Pokemon that has cream colored fur. Rather than having a fur mane, Ponyta has one made of fire, which burns when it is happy or excited. On its heels are streaks of fire. About an hour after birth, its fiery mane and tail grow out, giving it an impressive appearance.

Special Abilities
Ponyta can have the ability Flash Fire or the ability Run Away. Flash Fire allows Ponyta to be immune to all -type moves and increase its Attack if it is hit by these moves.
