Raichu is a rather small tailed bipedal rodent. It is 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, black tail has a broad, lightning bolt-shaped end. Unlike Pikachu, however, it's fingers doesn't seem to show.
Raichu is orange in color, with a white belly. Its arms are halfway brown, as well as its feet. The soles of its big feet are tan pink 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. Its height is 2'07" and weight is 66.1 lbs.
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 and increase them 10 times stronger to cause even a legendary Pokémon to be unconscious. 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 slightly glow in the dark. Raichu is also capable of wielding various fighting moves, such as Focus Punch, Brick Break and many more. As Raichu is a fully evolved Pokémon, it is capable of using powerful moves like Hyper Beam and Giga Impact.
Raichu is much more aggressive than Pikachu, especially if it has stored too much electricity in its body. It needs to discharge this electricity through its tail into the ground, leading to scorched patches of earth near its nest. However, Raichu can sometimes be timid Pokémon, using Dig to hide or zapping people from fear, especially if it thinks its Trainer is scared of it, as shown in Stage Fight!.
It will constantly electrify objects, people, and Pokémon until its electricity level is back to normal. When searching for electricity, Raichu will raise its tail to gather electricity from the atmosphere or plant its tail in the ground.
