What if two Pokemon with the same weight used heavy slam?

Question

Example. An Aggron battling another Aggron. Would the attack do any damage?

Answer 1

Deals damage. The power of this move depends on (user's weight / target's weight), rounded down. Power is equal to 120 if the result is 5 or more, 100 if 4, 80 if 3, 60 if 2, and 40 if 1 or less.

So, the users weight / the targets weight is 1, because they have the same weight here. And 1 as a result is 40 power, as mentioned above. Now, here's some damage calcs.

252+ Atk Choice Band Aggron Heavy Slam (40 BP) vs. 116 HP / 0 Def Aggron: 58-69 (18.7 - 22.25%) -- possible 5HKO

252+ Atk Choice Band Aggron Heavy Slam (40 BP) vs. 4 HP / 0 Def Aggron: 58-69 (20.56 - 24.46%) -- guaranteed 5HKO

So it just won't do much.

Hope I helped! :)

No problem :P

Answer 2

If one Aggron has the Heavy Metal abiltiy, it will have a slightly better advantage. But if both have Heavy Metal or if they both don't, they won't do much damage to eachother.
