Raichu

Raichu (Japanese: ライチュウ Raichuu) is an -type Pokémon introduced in Generation I.

Appearance
Raichu is a rodent-like Pokémon, sort of similar to its previous forms. Unlike Pichu or Pikachu, which both have yellow fur, Raichu has an orange-brown fur. It's has long ears, feet, but stubby arms with no fingers. Additionally, its electrical sacs are yellow, unlike its previous form's red coloring.It has a white belly, the tips of its arms and toes are brown. The soles of its feet are tan-colored and the paw pads on the undersides are yellow-ish orange. Raichu also have a long, thin, black tail that ends in a large lightning bolt shape. Male Raichus have larger "lightning bolt tails" than females. They are also bigger than their previous evolved forms.

Special abilities
Raichu has the ability Static and the hidden ability Lightningrod. Static allows Raichu to paralyze its foe when making a physical move. Lightningrod allows Raichu to draw in all -type attacks.

In the anime
Raichu made its debut appearance in the episode Electric Shock Showdown, under the ownership of Lt. Surge, the Gym Leader in Vermilion City. In this episode Ash's Pikachu is defeated in a one-on-one battle with Lt. Surge's Raichu, which then leads to Surge commenting on how Ash could never defeat his Raichu because his Pikachu was too weak.

Ash and Pikachu both, refusing to go through with evolving Pikachu in order to increase its power, face off against Lt. Surge again, this time using speed rather than power. By tiring Raichu out, Pikachu defeats Raichu and wins the battle.

Another Raichu, under the ownership of a trainer named Sho, was seen in Pika and Goliath!. Sho's Raichu used Hyper Beam at point blank range on Ash's Pikachu causing it to be in critical condition. This episode was very similar to the previously mentioned Electric Shock Showdown episode.

Another Raichu, named "Sugar" was seen under the ownership of an elderly woman named Abigail in the episode Cooking up a Sweet Story.

In the first episode of the Summer Camp for Pokemon episodes, Ash was given a Raichu to train and battle who was shy but warmed up to Ash but Ash had to return it after the battle.

Evolution
Raichu is the evolved form of Pikachu, and the final evolutionary form of Pichu. Pikachu can evolve into Raichu by the use of a Thunder Stone.
