Aggron's poor special defense means it can't take special attacks, and his poor typing gives him a x4 weakness to the ever common ground and fighting moves, making its physical defense a moot point. It has a niche in the form of recoilless Head Smashes and the ability to try to sweep by setting up using Rock Polish, but this wasn't enough to make it have use in OU. However, Aggron is one of the Pokémon to get a mega evolution, and it's a great one. It loses its rock-typing, gets increased special defense, gains the ability filter, and its defense goes through the roof. Not only that, but its attack goes up to a great base 140. All of this combined makes Mega Aggron is a defensive behemoth, tanking physical hits like they're nothing and hitting back hard. Polished Steel Aggron Aggron @ Life Orb / Aggronite Ability: Rock Head / Filter EVs: 252 Atk / 252 Spd / 4 Def Nature: Adamant - Iron Head / Heavy Slam - Earthquake - Head Smash / Stone Edge / Fire Punch / Ice Punch - Rock Polish / Autotomize With a Rock Polish up, Aggron becomes blisteringly fast, outrunning most unscarfed Pokémon. It's high defense means it can find plenty of opportunities to set up. Iron Head is your STAB, Earthquake is great coverage, and the third move is another coverage option. Head Smash is a must if you're using regular Aggron, while Mega Aggron would prefer Stone Edge or Fire Punch. Autotomize can be used, though it will weaken Heavy Slam if you're using it. RestTalk Megaggron Aggron @ Aggronite Ability: Sturdy / Filter EVs: 252 SpDef / 252 Atk / 4 HP Nature: Adamant / Careful / Impish - Iron Head / Heavy Slam - Curse / Dragon Tail / Roar - Rest - Sleep Talk A standard RestTalk set. Iron Head or Heavy Slam for damage, Curse as your boosting move, and the obvious Rest and Sleep Talk for a semi-decent recovery option. Dragon Tail or Roar can be used if you'd prefer phazing over boosting. Physical Tank Megaggron Aggron @ Aggronite Ability: Sturdy / Filter EVs: 252 Def / 252 Atk / 4 HP Nature: Adamant / Impish - Iron Head / Heavy Slam - Earthquake - Stealth Rock / Thunder Wave / Fire Punch / Stone Edge / Ice Punch - Dragon Tail / Thunder Wave / Roar / Fire Punch / Stone Edge / Ice Punch With max investment, Aggron gets the most terrifying physical defense in the game, allowing it to tank almost any physical hit with ease. The first two slots are your STAB and coverage, while the last two slots depend on what you want Aggron to do for you and your team, with your choices of either more coverage or more support. The attack EVs can be put into HP if you want to be able to tank even the hardest hitting moves, such as Close Combat from Terakion. Checks and Counters Aggron's biggest problem is its mediocre special defense and low speed. It will go down pretty quickly against Pokémon like Hydreigon, Heatran, and Megazard Y, all of which outspeed it. In addition, residual damage will work wonders against it, as Aggron has no reliable recovery. Burn almost completely shuts Aggron down, as it neuters its attack, leaving it unable to do much, and the burn damage will take its toll on Aggron's bulk. Wish and Heal Bell support are greatly appreciated for Aggron as a result. More sets will be added later. Feel free to post any ideas for sets you have, or comment on the sets listed here.
