Overview

At a glance, Aron seems to be a generic Rock-type Pokemon, with a great Defense stat and a good Attack stat. However, a closer look at Aron reveals that it has access to the combo of STAB Head Smash and the Rock Head ability, allowing it to do enormous amounts of damage without taking recoil. It also sports an impressive nine resistances and one immunity, making it very easy to switch in and start wrecking havoc. Nonetheless, the tiny iron Pokemon is not without its flaws. The current metagame is crawling with Fighting-type Pokemon, all of which can quickly dispose of Aron. In addition to this, Aron's abysmal Speed stat means it will be easily revenge killed by faster Pokemon.

Rock Polish

Life Orb Rock Head Jolly / Adamant
Moveset EVs
~ Rock Polish
~ Head Smash
~ Iron Head
~ Earthquake
196 Atk / 116 SpD / 196 Spe

This set is Aron's best shot at sweeping. Aron's horrible Speed stat significantly limits its sweeping potential, and Rock Polish is a great solution to this problem. After a single Rock Polish, Aron hits 26 Speed assuming a Jolly nature, outspeeding all unboosted Pokemon in Little Cup while getting the jump on Choice Scarf users with up to 17 Speed. This turns Aron into a formidable late-game sweeper. Sadly, setting up a Rock Polish is not easily accomplished because of the plethora of Fighting-types running around. Thanks to Aron's many resistances, though, it is possible with the correct team support. Head Smash is what makes Aron so dangerous, as it seriously dents anything that doesn't resist it. Iron Head is used for secondary STAB and has decent neutral coverage with Head Smash. Earthquake rounds out the coverage nicely, hitting any Steel-types except Bronzor.

Choice Band

Choice Band Rock Head Adamant
Moveset EVs
~ Head Smash
~ Iron Head

~ Superpower
196 Atk / 116 SpD / 196 Spe

With a Choice Band equipped, Aron becomes an immediate threat, boasting an Attack stat of 26 and a STAB 150 Base Power attack in Head Smash. The power of this set allows Aron to 2HKO almost everything in the tier, making it extremely hard to check. However, because this set trades Speed for power, Aron must be wary of any Pokemon faster than it, or else it will be revenge killed rather quickly. Head Smash has the sheer power and ability to break through many walls that Aron would usually have trouble with, such as Slowpoke. Iron Head, while not as powerful as Head Smash, still hits hard and is able to hit any Fighting- or Ground-types that resist Head Smash. Earthquake has great coverage with Head Smash and Iron Head, OHKOing most, if not all, Steel-types. Superpower is mainly on this set for its ability to hit Bronzor and Ferroseed, which otherwise wall this set. Still, Bronzor only takes a maximum of 40% from Superpower, so packing another Pokemon to beat Bronzor is recommended.

Other Options

Aron can run other sets, but they are generally outclassed by other Pokemon, or they are just too gimmicky. Stealth Rock and Roar along with the ability Sturdy can be used to make a decent lead set, but Dwebble does a much better job as a lead because it also has access to Spikes, and it's faster. A Hone Claws set can be used to boost Aron's Attack, but Aron will find it hard to set up. Also, Aron will be much too slow to sweep without a Speed boost. A defensive set with Eviolite can be used, but Aron has too many common weaknesses to be an effective tank. Metal Burst and Sturdy is an option to bait Fighting-types and OHKO them, but after Aron succeeds at doing this it's basically death fodder for the rest of the match. Iron Tail can be used on any of the sets listed above for more power instead of Iron Head, but the 75% accuracy is very unappealing. Aron can also utilize Magnet Rise to avoid Ground-type attacks, but it's not worth the turn it takes to set up. Even with Magnet Rise in effect, Aron still has two other common weaknesses.

Checks and Counters

Countering Aron is simple because of its common weaknesses. Any Fighting-type such as Mienfoo, Scraggy, or Timburr can OHKO Aron, assuming Sturdy is not in play. Bronzor, Slowpoke, and Hippopotas can wall Aron most of the time, but Slowpoke must be careful of Choice Band Aron. Priority moves including Mach Punch and Aqua Jet will leave a huge dent in Aron, if not KO it. Any Pokemon that can outspeed Aron and hit it with a super effective attack, such as Staryu, will beat it.
