Overview

Aggron is the very definition of scary; wearing a skull helmet topped with razor-sharp horns, carrying bullet-proof steel armor, and wielding lethal claws, there are few opponents that can even think about standing up to the metal beast. However, Aggron isn't all bark and no bite, as its Rock Head ability allows it to pummel opponents with the powerful Head Smash without any recoil. Defensively, Aggron is also a monster to deal with, as its whopping base 180 Defense and plethora of resistances courtesy its Steel typing enables it to comfortably take on most physical threats. Unfortunately, its typing also comes with the drawback of 4x weaknesses to the common Fighting- and Ground-type attacks thrown around in the tier. Aggron's lackluster Special Defense also lets it down when it comes to taking special hits; as it easily falls to moves such as Scald. Although Aggron is a rather unbalanced Pokemon in terms of stats and typing, use it correctly and you will find that it is a diamond in the rough.

Choice Band

Choice Band Rock Head Adamant
Moveset EVs
~ Head Smash
~ Heavy Slam
~ Earthquake
~ Fire Punch / Aqua Tail
116 HP / 252 Atk / 140 Spe

With a Choice Band wrapped around its head, Aggron becomes a truly terrifying foe to face, as only the bulkiest of threats will be able to take its blows and retaliate. Its Choice Band-boosted Head Smash is something that every RU team must prepare for, lest they be shredded by its power. Adding insult to injury, Aggron takes no damage from this risky attack thanks to Rock Head. Unfortunately for Aggron, there are a few Pokemon that can switch into Head Smash and retaliate; for these, Aggron can use its alternative STAB move, Heavy Slam. As Aggron is very heavy, Heavy Slam will more often than not be hitting at full power. Earthquake gives Aggron outstanding coverage alongside Head Smash. With it, Aggron can smite Steelix and opposing Aggron, both of which would otherwise be able to bring it down. Fire Punch is the recommended choice in the last slot to hit unsuspecting Ferroseed, but Aqua Tail can be used instead to hit Pokemon such as Rhydon harder than the other moves. Choice Band Aggron is primarily a wallbreaker and should be used as such; it can easily switch in on Pokemon such as Cinccino and Escavalier and either devastate them with Head Smash or hit the predicted switch-in with one of its other high-powered moves.

SubPunch

Leftovers Rock Head Adamant
Moveset EVs
~ Substitute
~ Head Smash
~ Focus Punch
~ Magnet Rise / Toxic
116 HP / 252 Atk / 140 Spe

Aggron's powerful move, Head Smash, is known and feared. It can use that fear to set up a Substitute as the opponent switches out to a Pokemon resistant to Rock-type moves. Steelix and Ferroseed are common switch-ins that get blown away by the impending Focus Punch. Substitute also protects Aggron from status such as burn and sets up a shield against weak, resisted moves such as U-turn. Head Smash achieves incredible power despite the lack of a boosting item and is Aggron's strongest move. Focus Punch decimates common Aggron switch-ins such as Steelix and Ferroseed and has great neutral coverage alongside Head Smash. Magnet Rise is the main move in the last slot to thwart Sandslash's and Steelix's attempts to break Aggron's Substitute with Earthquake. With a temporary immunity to Ground-type moves, Aggron can render many Pokemon incapable of harming it as it sets up a Substitute in their faces. Toxic is an alternative to surprise walls such as Quagsire and Tangrowth and limit their walling capabilities.

Rock Polish

Life Orb Rock Head Adamant
Moveset EVs
~ Rock Polish
~ Head Smash
~ Earthquake
~ Heavy Slam
4 HP / 252 Atk / 252 Spe

Aggron's Speed is the only thing holding it back from a sweep, so Rock Polish is an amazing move for it. With Rock Polish, Aggron can outspeed most of the metagame and potentially sweep weakened or unprepared teams. This is aided by the fact that Aggron can easily force switches, giving it time to set up Rock Polish and go on a Speed-boosted rampage. Head Smash is Aggron's most powerful move and is what makes it so threatening; frailer Pokemon such as Rotom are easily OHKOed, while even bulky walls such as Tangrowth can be 2HKOed by it. Earthquake gives Aggron nearly unresisted coverage alongside Head Smash and has a respectable amount of power in its own right; in addition, it gives Aggron a move to hit opposing Aggron and Steelix, both of which would otherwise wall it. Heavy Slam is the best move in the last slot as it lets Aggron take down Rhydon and Sandslash, two Pokemon that can easily sponge Earthquake and retaliate with an Earthquake of their own, it also provides Aggron with a powerful and consistent secondary STAB attack to use when Aggron cant risk relying on Head Smash's shaky accuracy. Although Aggron still boasts incredible power when holding a Life Orb, it is best if physical walls are weakened or removed before Aggron attempts to sweep. Choice Scarf holders such as Rotom-C and Manectric can outspeed Aggron even after an Rock Polish, so they too should be taken care of before Aggron sweeps.

Other Options

Although Aggron is normally seen as an offensive Pokemon, it can also run a decent support set thanks to its rather overlooked base 180 Defense. Like most Rock-types, Aggron has the almost mandatory Stealth Rock as well as niche moves such as Metal Burst and Taunt. Metal Burst is particularly effective when used in conjunction with Taunt, as the opponent will be forced to attack Aggron. Taunt can prevent Poliwrath from healing itself with Rest and Tangrowth from using status moves or Leech Seed. Hone Claws and Curse are two boosting moves that Aggron can use with decent results; Hone Claws boosts the accuracy of Head Smash, Iron Tail, and Aqua Tail while also boosting Aggron's great Attack stat. Unfortunately, it doesn't boost Aggron's Speed or Special Defense, which means Aggron can be easily revenge killed. Curse suffers from the same problem, and although it also increases Aggron's already excellent Defense, most Ground- and Fighting-type attacks will still OHKO. Dragon Tail is an interesting move for Aggron as the latter forces numerous switches and can rack up entry hazard damage; after its counters have been sufficiently weakened by entry hazards, Aggron can potentially sweep. Lastly, Aggron can try to rectify its poor Speed with a Choice Scarf. While this lets Aggron outspeed many Pokemon that it wouldn't normally, Aggron's Speed is just too low to make it as effective as other Choice Scarf users.

Checks and Counters

Quagsire, Poliwrath, and Torterra are some of Aggron's best counters as they can switch into almost all of Aggron's commonly used moves, fearing only Toxic, and Fire Punch in Torterra's case. They can all decimate Aggron with super effective STAB Earthquake or Circle Throw. Tangrowth is also a great check to Aggron as it only fears Choice Band-boosted Head Smash, which can 2HKO; otherwise, it can tank Aggron's hits and either put it to sleep or hit its weaker Special Defense with Giga Drain or Leaf Storm. Steelix and Ferroseed are commonly-seen switch-ins to Aggron, as they are among the few Pokemon in the tier that can shrug off Head Smash; however, they are both 2HKOed by Focus Punch after a layer of Spikes. Sandslash can also sponge Aggron's Head Smash and retaliate with Earthquake; it only has to fear Aqua Tail, and even then it can survive one. If you don't have one of the few Pokemon that can switch into Aggron, then you will have to resort to revenge killing it. Sets that run Choice Band are quite easy to revenge kill as they cannot boost their Speed. Rock Polish sets are harder to deal with but can still be outsped by fast Choice Scarf users. For instance, Choice Scarf Rotom-C and Manectric can both outspeed +2 Aggron and revenge kill it. Priority moves from the likes of Hitmonchan are also a great way to check Aggron; however, not even a Choice Band, Iron Fist-boosted Mach Punch can OHKO Aggron at full health, so it should only be used when Aggron has been weakened.
