only aggron can use it, and an ability that affects just one of his moves AND lowers low kicks damage (which isnt a common move by any means) isn't doing aggron many favors. Hard to pass up sturdy for this as well --- Welcome to Gamefaqs: Where adults argue with children. Constantly. Over nothing. (Y) People who agree: Several
I rate it the worst. It has almost no use, since Heavy Slam and Heat Crash are not only rather exclusive moves, but even if that weren't the case, you won't be hitting with full power in most cases unless the user is extremely heavy hitting something extremely light. So...in most cases, moves with the same type and often secondary effects are better. And the biggest part is that it increases damage from Low Kick and Grass Knot, which are not so exclusive moves.
Aggron would much rather have rock head, and grass knot is relatively common, so I can't see many scenarios where this would be helpful. Now, if aggron did choose to use it, and got low kicked, then you would have one very sad aggron on your hands. --- "it's that game that is so great it makes you want to destroy your Toilet." -Throwback2780
Can lead up to a few nice surprises, but too few attacks from the PokÚs who have Heavy Metal actually utilize weight - it's really an Aggron only thing. --- "Evil, beware. We have waffles..." - Raven, Teen Titans
