Jolteon (Japanese: サンダース Thunders) is an Electric-type Pokémon. It evolves from Eevee when exposed to a Thunderstone. It is one of Eevee's final forms, the others being Vaporeon, Flareon, Espeon, Umbreon, Leafeon, and Glaceon.
Jolteon is a dog-like Pokémon with a very short tail, surrounded by a fringe of spikes on its rear. It has four slender legs, each with a three-toed foot and a pink paw pad. It has large, pointed ears with black insides. Jolteon is covered in yellow fur, and has a white, spiky collar. It can make its fur sharp like needles; this is similar to Glaceon, which also has fur that can be made sharp. Jolteon has dark, fox-like, black eyes.
