Aggron can have one of two abilities: Sturdy, which nullifies the effect of one-hit KO moves on it, and starting with Generation V, prevents it from being Knocked Out in one hit--if its HP is full, an attack that would have caused a KO will leave it with 1 HP; or Rock Head, which nullifies recoil from moves such as Double-Edge or Head Smash. Aggron from the Dream World have access to a third Ability, the Heavy Metal Ability. This ability doubles its weight in battle, affecting how much damage it would take from Grass Knot or Low Kick as well as how much damage it can deal out from the attack Heavy Slam.
Aggron is in the Monster Egg Group, and its Egg takes approximately 8,960 Steps to hatch. It takes Aggron 1,250,000 Experience Points to reach Level 100.
Aggron resembles something from the prehistoric era in which dinosaurs ruled the Earth. In addition to being clad in armor, it has two horns protruding from its head, and part of its head has formed a third horn. This part resembles a Triceratops, albeit longer horns and a bipedal Pokémon.
Aggron doesn't have any differences to differentiate between male and female.
While it isn't a Shadow Pokémon, an Aggron can still be obtained in Pokémon XD: Gale of Darkness by capturing an Aron at the Cave Poké Spot, a place to find Wild Pokémon in the Orre Region, and evolving it twice.
Aggron makes appearances at Phobos Drill, Trozei Battle and Mr. Who's Den in Pokémon Trozei!.
Aggron can only be obtained by evolving a Lairon in the first Mystery Dungeon game. In Explorers of Time, Explorers of Darkness and Explorers of Sky, Aggron appears on the first 12 floors of Deep Dusk Forest. However, this Pokémon cannot be recruited, so the only way to obtain one is by evolving a Lairon, just like in the prequel. Aggron appears in all three versions of Mystery Dungeon 3 on floors 21-29 of each game's respective Secret area. Additionally, Aggron also appears on floors 1-16 & 18-25 in the Legendary Areas of Stormy Adventure Squad and Light Adventure Squad.
Aggron appears in Pokémon Ranger: Shadows of Almia at Volcano Cave. Aggron returns in Pokémon Ranger: Guardian Signs on the 3F's Left Observation Room of the Air Fortress in the Present; and the Fire Temple mission "Shaken by Aggron's Footsteps" by capturing it or another form in its evolutionary line and obtaining its Slate, but the slate can only be kept if the Boss is defeated within the time limit. Aggron also appears in the Odd Temple mission "Deoxys & The Mysterious Temple," a Downloadable mission that will require two-player co-op at the minimum to clear.
The only way to obtain an Aggron in Pokémon Conquest is to evolve a Lairon.
Aggron can be found at Volcanic Slope Canyon 3-2 in Pokémon Rumble Blast after completing the game.
Trading Card Game
Aggron appears in 10 different sets. It is listed as a Rare Card in the EX Ruby and Sapphire, EX Sandstorm (EX Card), EX Team Magma vs Team Aqua, EX Legend Maker, EX Crystal Guardians (EX Card), EX Power Keepers, Mysterious Treasures, Rising Rivals, Triumphant and Dragons Exalted Sets.
Steven Stone used an Aggron to thwart Team Rocket's usual mischief in the episode A Hole Lotta Trouble!!. More recently, Paul used an Aggron in his Sinnoh League Quarterfinal battle against Ash. It would force Ash's Pikachu to retreat, but it suffered a Burn from-and was defeated by-Ash's Infernape, the first fall of the full 6-on-6 battle.
Another trainer used an Aggron in the film Jirachi Wishmaker and Lucario and the Mystery of Mew. Wild Aggron appeared in the films Giratina and the Sky Warrior and Zoroark: Master of Illusions, along with the Pikachu Short Pikachu's Summer Festival.
Aggron's Manga info is unknown at this time.
Aggron is a part of the Neverused (NU) tier of competitive battling. With a high Attack stat and a strong STAB in Head Smash that complements its ability Rock Head extremely well, Aggron can fire off insanely powerful Choice Band-boosted attacks without taking any recoil. It is capable of threatening two of the tier's bulkiest Pokémon in Musharna and Mega Audino without having to worry too much about losing offensive merit against slower threats. Aggron is very destructive against slower teams, as it can fire off its powerful attacks at will without having to worry about the threat of being picked off easily. It has solid coverage to boot, with STAB Heavy Slam, Superpower, and Ice Punch to complement its powerful STAB in Head Smash very well. However, Aggron's matchup against offense is poor due to low Speed and a bad defensive typing, with x4 weaknesses to both Ground and Fighting, coverage types that Normal-types commonly use. Aggron also has a low Special Defense stat that undermines some of its resistances, which leads to it being hit hard even by resisted attacks. Aggron's lack of ability to stop Normal and Flying-types due to its flaws compounds weaknesses on a team due to the need for another Pokémon to check them while likely sharing the same weaknesses.
Aggron is also viable in the Rarelyused (RU) tier of competitive battling. With a massively powerful attack in Head Smash, Rock Head to negate Head Smash recoil, and a nice Attack stat to boot, Aggron is among the tier's best wallbreaking threats. It has some very good coverage attacks to hit foes that resist its powerful Head Smash, with Heavy Slam, Low Kick, and Fire Punch, which can hit the likes of Flygon, Rhyperior, and Steelix very hard. Aggron does have its flaws that restrict it from being a dominant force, though, as its base 50 Speed and x4 weaknesses to Fighting and Ground often make it candidate to be forced out after it gets a KO. It has poor HP and Special Defense stats, which undermine its incredibly high Defense stat and resistances, while giving it a poor matchup against a lot of the tier's special attackers.
