A Light Ball is a held item that doubles Pikachu's Attack and Special Attack. If a Pikachu holds a Light Ball while breeding, the offspring Pichu will know the move Volt Tackle. A Light Ball has no effect when held by any other Pokémon, including Pichu and Raichu. It can be obtained as a tier 2 special drop. It is also a drop from wild Pikachu and Raichu.
