Effects

Ratio (r)Power
5 ≤ r      120
4 ≤ r < 5100
3 ≤ r < 480
2 ≤ r < 360
r < 240

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.

Changes

In Generations 5-6, the Minimize effect did not occur.

Z-Move effects

When a Pokémon is holding Steelium Z and uses its Z-Power, Heavy Slam turns into Corkscrew Crash and has base power 160.
