Overview

Aggron can certainly prove to be a headache for any player that goes up against it; with a respectable base 110 Attack and an amazing 150 Base Power STAB move, very few Pokemon can safely switch into Aggron. Unfortunately, Head Smash is really the only thing Aggron has going for it, and it has a lot of things going against it. Abysmal Speed, a horrendous defensive typing with two 4x weaknesses, and lack of special bulk all make it difficult for Aggron to survive for long in battle. However, if Aggron can find an opportunity to use Head Smash, it will usually pay off.

Choice Band

Choice Band Rock Head Jolly / Adamant
Moveset EVs
~ Head Smash
~ Heavy Slam
~ Earthquake
~ Aqua Tail / Superpower
4 HP / 252 Atk / 252 Spe

Aggron becomes absurdly lethal when equipped with a Choice Band. Head Smash deals devastating amounts of damage, and Aggron's Rock Head ability blocks recoil, allowing Aggron to use the attack with no risks, save for Head Smash's accuracy. This set focuses on abusing Head Smash, while the rest of the moves cover the Pokemon that resist it. Heavy Slam is a secondary STAB move, and it provides coverage on Fighting-types that resist Head Smash, such as Hitmontop. Earthquake deals with most Steel-types, including Registeel and Empoleon. Aqua Tail nails Ground-types, such as Golurk, Nidoqueen, and Claydol, while Superpower is Aggron's strongest move against Steelix, Empoleon, and Registeel.

Autotomize

Life Orb / Chople Berry Rock Head Adamant / Jolly
Moveset EVs
~ Autotomize
~ Head Smash
~ Aqua Tail
~ Low Kick / Magnet Rise
4 HP / 252 Atk / 252 Spe

Autotomize patches up Aggron's Speed, allowing it to pose more of a threat to offensive teams. Head Smash is obviously Aggron's STAB move of choice, and a powerful one at that. Aqua Tail covers Ground-types that resist Head Smash. Low Kick helps deal with most Steel-types, while Magnet Rise allows Aggron to beat walls that can only threaten it with Ground-type moves.

Other Options

Aggron can take advantage of its low Speed and other ability, Sturdy, to OHKO nearly any attacker with Metal Burst. Unfortunately, this keeps it from using Head Smash effectively. Aggron also has a decent selection of support moves, including Stealth Rock, Toxic, and Thunder Wave. Aggron can use a Hone Claws set to increase Head Smash's accuracy, but it is generally too slow to pull it off effectively. A set utilizing Substitute and Focus Punch to soften up Pokemon that resist Head Smash, such as Steelix and Registeel, is also an option. With entry hazard support, Aggron can also take advantage of Dragon Tail or Roar to soften up Pokemon that attempt to switch into it.

Checks and Counters

Hitmontop can switch into Head Smash and can revenge kill the Autotomize set with Mach Punch, but it should be wary of Heavy Slam, which can 2HKO after Spikes even after an Intimidate. Bulky physical walls that resist Head Smash also check Aggron effectively, especially Steelix and Nidoqueen, both of which threaten Aggron with STAB Earthquake. Because of its special frailty, nearly any Pokemon with a super effective special move threatens Aggron. Many Pokemon that threaten Aggron also outspeed it, such as Suicune with at least 52 EVs invested in Speed, so it is not very difficult to revenge kill.
