Heavy Slam deals varying damage depending on the weight of both the user and the target. The heavier the user is in comparison to its target, the more damage will be inflicted. The base power varies as follows:

- 120 base power, if target's weight is less than or equal to ⅕ (20%) of user's weight.

- 100 base power, if target's weight is greater than ⅕ (20%) of user's weight and less than or - equal to ¼ (25%) of user's weight.

- 80 base power, if target's weight is greater than ¼ (25%) of user's weight and less than or equal to ⅓ (33.3%) of user's weight.

- 60 base power, if target's weight is greater than ⅓ (33.3%) of user's weight and less than or equal to ½ of user's weight (50%).

- 40 base power, if target's weight is greater than ½ (50%) of user's weight.

I need the Pokemon Aggron is using Heavy Slam on to calculate the power.
