Is there an Item in Pokemon Sapphire that doubles the user's weight?

Question

I am doing my Dream Team in Sapphire on Pokemon Online and I need Heavy Slam but I don't know how much Aggron weighs and if there is an item that raises their weight.
HELP!

Comments

Heavy slam does not exist in Sapphire it was introduced in Gen V.

Answer 1

There is no item that makes a pokemon heaver. The only way to increase weight is by the ability heavy metal, which is found on aggron as a DW ability.

Aggron's Weight: 793.7 lbs (360.0 kg)
With Heavy Metal: 1587.4 lbs (720.0 kg)
