Ponyta

Ponyta is a -type Pokémon introduced in Generation I.

Appearance
Ponyta is a horse Pokémon 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. Run Away allows Ponyta to run from all wild Pokémon battles. After birth, it is weak. However, as it runs, it gets stronger. It is known to run fast and jump high. Its hooves are harder than diamond and its legs are strong a durable; able to absorb the shock from taking high jumps. It allows humans to ride on its back occasionally. However, if angered, it may choose to burn its rider by igniting its back.

Evolution
Ponyta evolves into Rapidash at level 40.

Trivia

 * Despite Ponyta's Diamond Pokédex Entry saying that it takes an hour for its flames to appear after its birth, it instantly appears in the games when a newborn Ponyta is hatched.
 * Ponyta is one of the fourteen Pokémon able to collect a foreign Pokédex Entry in Pokémon Diamond and Pearl.
 * In the anime, Ash rides a Ponyta (which evolves into Rapidash in the same episode) but in "reality" a Ponyta would be too small to ride.
