Jolteon

Jolteon (Japanese: サンダース Sandaasu) is a -type Pokémon introduced in Generation I.

Physiology
Jolteon is a quadrupedal mammalian feline Pokémon that resembles a cheetah (with some traits of a jackrabbit). Jolteon's body is covered in spiny bright yellow fur. It has long rabbit-like ears, deep purple almond-shaped eyes, and a blunt muzzle (similar to that of a wildcat) with a small black triangular nose. It has a spiky white mane encircling its neck. Its legs and paws are slender and catlike, with three toes on each and no visible claws; however, in The Electric Tale of Pikachu manga, Sparky's Jolteon is shown to be able to extend and retract its claws like a cat. Jolteon has a spiny fringe of fur covering its backside, and it has a small short spike-like tail that is not often visible (but seen in games such as Pokémon Stadium). Its back legs seems to be powerfully-built, allowing it to run at high speeds.

Special abilities
Jolteon have the ability Volt Absorb. This allows Jolteon to absorb any -type move and heal itself. Jolteon is able to gather negative ions from the atmosphere, using the resulting electricity to create lightning bolts of up to 10,000 volts. Its individual cells also create small electrical charges on their own, which combined with the static electricity caused by its body can result in powerful electric-type attacks. It is very sensitive and temperamental, which causes it to constantly charge as it quickly changes moods. It can also make lightning and cause small thunderstorms. When threatened or angered, its fur stands on end and becomes sharp bristles, and it will fire these electrified needles from its body. Like cheetahs and jackrabbits, Jolteon are known for their incredible speed.

Evolution
Jolteon is one of the eight evolutions of Eevee. Its evolution is caused by the radiation from a Thunder Stone.

Origin
Like all Eeveelutions, physiologically, Jolteon resembles a feline, specifically resembling a cheetah on account of its yellow coloration and main attribute of speed. Its facial and body structure is reminiscent of a wildcat. When attacking, Jolteon is seen standing with its fur on end and its four legs splayed out, opening its mouth widely as if it is hissing; this motion is highly reminiscent to the stance of a threatened or angered cheetah, which hisses and jolts forward with its legs splayed out and fur standing on end. Jolteon also bears some resemblance to a jackrabbit, an animal also known for its speed.

Etymology
Jolteon's English name comes from "jolt" and "eon", much like Flareon and Vaporeon. Also, its Japanese name, Saandazu, which is read Thunders, is a pun about its electrical nature.
