Pokédex Entries

Generation I

• Red and Blue Version: When several of these Pokémon gather, their electricity could build and cause lightning storms.
• Yellow Version: It keeps its tail raised to monitor its surroundings. If you yank its tail, it will try to bite you.

• Gold Version: This intelligent Pokémon roasts hard berries with electricity to make them tender enough to eat.
• Silver Version: It raises its tail to check its surroundings. The tail is sometimes struck by lightning in this pose.
• Crystal Version: When it is angered, it immediately discharges the energy stored in the pouches in its cheeks.

• Ruby Version: Whenever Pikachu comes across something new, it blasts it with a jolt of electricity. If you come across a blackened berry, it's evidence that this Pokémon mistook the intensity of its charge.
• Sapphire Version: This Pokémon has electricity-storing pouches on its cheeks. These appear to become electrically charged during the night while Pikachu sleeps. It occasionally discharges electricity when it is dozy after waking up.
• Emerald Version: It stores electricity in the electric sacs on its cheeks. When it releases pent-up energy in a burst, the electric power is equal to a lightning bolt.
• FireRed Version: It has small electric sacs on both its cheeks. If threatened, it looses electric charges from the sacs.
• Leaf Green Version: When several of these Pokémon gather, their electricity could build and cause lightning storms.

• Diamond Version: It lives in forests with others. It stores electricity in the pouches on its cheeks.
• Pearl Version: If it looses crackling power from the electrical pouches on its cheeks, it is being wary.
