Pikachu is one of the most popular Pokémon in the world, and its signature ability is to generate electricity. Pikachu's lightnings are actually caused by a buildup of static electricity. Pikachu's fur is very good at generating static electricity, and when it comes into contact with another object, the electricity is released in the form of a lightning bolt. Pikachu's lightnings are not just for show. They can also be used as a weapon. Pikachu can use its lightnings to attack enemies, and it can also use them to create powerful electric fields.
