Heavy Slam inflicts more damage the heavier the user compared to the opponent. The table 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.
If the target has used Minimize, Heavy Slam ignores accuracy and deals double damage.
When a Pokémon is holding Steelium Z and uses its Z-Power, Heavy Slam turns into Corkscrew Crash and has base power 160.
