Heavy Slam is a Steel-type move with variable power, which depends on the weight difference between the user and the target. The more the user outweighs the target, the higher the power of the move, potentially reaching up to 120. The accuracy of Heavy Slam is 100%, making it a reliable option in battle. Heavy Slam does not have a fixed power but can be particularly effective against lighter opponents. It is often used by heavier Pokémon, such as Steelix or Snorlax, to maximize damage output. This move does not have any secondary effects like causing status conditions.
