Thunder (かみなり Thunder) is a damage-dealing Electric-type Move introduced in Generation I. In the anime, Thunder is often used by Raichu that battle against Ash's Pikachu. The move resembles Thunderbolt then, but is more powerful. Pikachu also has learnt Thunder.
Thunder never misses in heavy rain, but has 50% accuracy in intense sunlight. It may also paralyze the target. It also hits Pokémon that are flying.
Startles all Pokémon that have already appealed.
