Stray Pikachu

Pikachu is a small Pokémon whose morphology is based on a rodent. Although its name and category refer to a mouse, according to its designer, its cheeks are based on those of a squirrel. Its body is yellow with two brown stripes on its back and at the base of its tail. The tips of its ears are black, and it has a large red circle on each cheek. It has a lightning bolt-shaped tail for males and a heart-shaped tail for females.

Pikachu stores a large amount of electricity in the sacs in its cheeks. These sacs appear to charge electrically during the night while it sleeps. It occasionally releases electricity while half asleep, as if dreaming it's giving off electric shocks. It occasionally releases small shocks after just waking up. Pikachu's cheeks can also be recharged by an electric shock delivered by another Pikachu. It is a very curious Pokémon, which is why it can often be seen near human settlements.

Pikachu's primary habitat is the forest, far from human settlements, where it can find berries, which it roasts with its electricity. So, if you find a scorched berry lying on the ground, it's very likely Pikachu's work. It likes to live in groups, where it always keeps its tail up in the air to keep watch. In this position, it can easily be struck by lightning, and if it feels threatened or disturbed, it will release all its stored electricity. The energy released by several individuals together is capable of generating thunderstorms.

Based on the Pokémon universe, this Pikachu can talk, something only a minority of Pokémon can do.
