Raises the user's Atk and Def.
Bulk Up is a Fighting-type status move that raises the user's Attack and Defense stats by one stage each. This dual stat boost allows the user to become more formidable in battle, enhancing both their offensive and defensive capabilities. Bulk Up has an accuracy of 100%, ensuring that it will successfully boost the user's stats unless affected by accuracy-reducing conditions. In Polished Crystal, Bulk Up can be learned by various Fighting-type Pokémon, providing them with a strategic option to strengthen themselves for prolonged battles.
