Well, here are some sets I made for the other Aggron thread before I realized this one already exists:
Body Purge
Aron @ Life Orb / Lum Berry / Balloon / Pumice Stone
EVs: 252 Atk / 4 Def / 252 Spe
Nature: Adamant (+Atk, -SpA) / Jolly (+Spe, -SpA)
Ability: Rock Head
- Body Purge
- Head Smash
- Earthquake / Aqua Tail
- Magnet Rise / Ice Punch / Aqua Tail
Seriously? I'm really surprised not to see Body Purge on the OP. :0 It's basically like Rock Polish? But it halves damage from Grass Knot and, more importantly, Low Kick? YESPLZ. Aparet from that, it's basically token RP Aggron movewise... Itemwise, I went a little crazy, but I thought Ballon / Pumice Stone further alleviating Aggron's weaknesses a little was cool.
Choice Band
Aggron @ Choice Band
EVs: 252 Atk / 4 Def / 252 Spe
Nature: Adamant (+Atk, -SpA)
Ability: Rock Head
- Head Smash
- Earthquake
- Aqua Tail
- Superpower / Ice Punch / Double-Edge
Basically the same set, I just threw in a few more options and removed Thunderpunch, which is dumb IMO because of all the things that can come in on it, immune, set up (Garchomp, Doryuuzu, olol) and have supereffective Ground STAB against Aggron, no less. I also agree with Forsety with regards to Heavy Bomber; it's really only effective with Heavy Metal, which compared to Rock Head and Sturdy is a pretty useless ability.
The poor thing got Heavy Metal in the Dream World?! That won't help it. Low Kick could probably KO it.
Aggron getting Heavy Metal (with relation to Low Kick) is like Parasect getting Dry Skin last gen... Making an already-lethal weakness into triple overkill, LOL. Only Heavy Metal is completely useless compared to its pre-existing abilitites. :0
Subgron
Aggron @ Leftovers / Lum Berry
EVs: 160 HP / 252 Atk / 12 SpD / 84 Spe
Nature: Adamant (+Atk, -SpA)
Ability: Rock Head
- Substitute
- Head Smash
- Focus Punch / Earthquake
- Magnet Rise
<3 Subgron. My favorite 4th-Gen Aggron set.
Potential Sets:
Sturdy Lead
Aggron @ Custap Berry / Lum Berry
EVs: 252 HP / 100 Def / 156 SDef (?)
Nature: Impish (+Def, -SpA)
Ability: Sturdy
- Stealth Rock
- Metal Burst
- Stone Edge
- Ice Punch / Dragon Tail / Rest
My version of the lead. Stone Edge and Ice Punch are options for hitting the many Mischeivous Heart Taunters, Dragon Tail is for Spikers/Taunting setup leads, etc, Rest is to preserve Sturdy Metal Burst for later use. Obv Rest needs Aromatherapy/Heal Bell support. Not really sure why Knock Down was listed here in the OP, it's only useful if you need to hit stuff with Ground (or maybe Arena Trapping), but Aggron has little use for it, IMO. :0
ShuffleTank
Aggron @ Leftovers / Lum Berry
EVs: 160 HP / 252 Atk / 12 SpD / 84 Spe (?)
Nature: Adamant (+Atk, -SpA)
Ability: Rock Head
- Head Smash
- Earthquake / Focus Punch
- Thunder Wave / Substitute
- Roar / Dragon Tail / Substitute
This set uses Aggron's bulk to attempt to spread paralysis around the enemy team. Thunder Wave helps Aggron's poor-ish speed, and Roar or Dragon Tail (depending on if you want to be able to phaze Subs or phaze when Taunted) spreads it around. Substitute can be utilized somewhere on the set, but you have to pick between paralyzing or shuffling foes when doing so. If you do opt for Sub, then Focus Punch is an option over Earthquake.
You're forgetting the obvious gimmick set.
Aggron @ Custap Berry
Ability: Sturdy
EVs: 252 Speed, 252 HP
Jolly nature
- Metal Burst / Counter
- Endeavor
- Rest
- Protect / Roar / Dragon Tail
I actually really like this set, gimmick or no, but it really needs Rest, IMO. It's not likely that Aggron will survive Metal Burst followed by Endeavor, but if it does, I'd definitely want to heal Aggron for rinse-and-repeat sessions later.
Also, I'd like to request that the Claw Sharpen sets be removed from the OP. :\ Claw Sharpen is pretty useless as a boosting move, for Aggron especially. Since his moves' accuracy is already quite acceptable, you're basically just using Sharpen. :0 Does anyone realize this? When has anyone (outside of Simple Pokes) EVER wanted to use Sharpen over something like Swords Dance or Dragon Dance? Sure, Aggron doesn't get those, but boosting with Claw Sharpen just takes too long and isn't worth the time it takes to get there; he'd rather just kill stuff with a Choice Band then waste 1-2 slots on making Claw Sharpen work.
