What is the point of the ability Heavy Weight?

Question

I stumbled upon this ability which doubles the Pokemon's Weight. What in the world could be it's use, other than receiving more damage from Grass Knot?

Answer 1

The moves Heat Crash and Heavy Slam are affected by the Pokemon's weight (relative to the opponent).

Aggron and Bronzong can both learn Heavy Slam, but not Heat Crash. Since they are already very heavy, this means the move will likely attack with 100 or 120 base power.

Not really an honor. He does it all the time. But you should give him best answer.

Or he can give best answer to whoever he feels has the better answer.

I should get Best Answer even though I didn't even answer.

oo that Trachy...

Answer 2

Aggron. If he uses the move Heavy Slam with this ability, it is deadly. Easy 120 damage on most Pokemon + STAB.
