Heavy Slam inflicts more damage the heavier the user compared to the opponent. The table to the right shows the different base powers for each ratio, where r = UserWeight ÷ TargetWeight

For example, if the user's weight is at least 4 times more than the target but less than 5 times, Heavy Slam hits with 100 base power.
