Pikachu made it's debut in Snivy, I choose you! as Amelia's starter Pokémon. She specifically requested Pikachu from the Professor. Pikachu had it's first battle against Jason's Snivy. It put up a good fight, but it fell to the Grass Snake Pokémon's power.
Raichu is a rather small bipedal rodent. It's able to run faster on all fours. Like Pikachu, from which it evolves, Raichu has long ears and feet, and stubby arms. Also like Pikachu, Raichu has two horizontal brown stripes on its back. Its long, thin tail has a broad, lightning bolt-shaped end. Unlike Pikachu however, it does not have fingers.
Raichu is yellow-brownish in color, with a white belly. Its arms are halfway brown, as well as its feet. The soles of its feet are tan colored. Its bifurcated ears are brown on the outsides and yellow on the insides, and end in a distinctive curl at their bottom-most point. The electric sacs on its cheeks are yellow.
A female Raichu has a smaller, blunted lightning bolt at the end of its tail.
Although quite small in comparison to many other Pokémon, Raichu is capable of storing over 100,000 volts of electricity in its body. If Raichu’s electricity sacs are fully charged, its ears will stand straight up. Raichu exudes a weak electrical charge from all over its body that makes it take a slight glow in the dark. Raichu is also capable of wielding various fighting moves, such as Focus Punch, Brick Break and many more. Now that Raichu is a fully evolved Pokémon, it is capable of using powerful moves like Hyper Beam and Giga Impact.
Raichu, and its evolution family, Pichu and Pikachu, are the only known Pokémon that can learn Volt Tackle.

In a few rare cases, Raichu (as a Pikachu) can learn to manipulate Water and, with the help of a surfboard, perform the move Surf. Other rare cases show that Raichu (as a Pikachu) can also learn, with the use of balloons, to perform the move Fly.
When an offensive move makes contact with Raichu, there is a 30% chance that the attacking foe will become paralyzed. This can affect Ground-type Pokémon.
