Generation III · #0306 — Iron Armor Pokémon
Aggron, known as the Iron Armor Pokémon, is a dual-type Steel and Rock Pokémon that represents the final evolution in the Aron evolutionary line, which begins in Generation III. With a National Pokédex number of 306, Aggron stands as an imposing creature reaching 2.1 meters in height and weighing a substantial 360 kilograms. This massive Pokémon evolves from Lairon starting at level 42 and serves as a powerful defensive wall in competitive and casual gameplay alike. Its base stat total of 530 points heavily favors defense, with an astounding base Defense stat of 180, making it one of the most defensively oriented non-legendary Pokémon in the game. Aggron's combination of types, abilities, and stat distribution has secured its position as a respected and frequently used Pokémon across multiple generations of games.

Aggron is a large, bipedal Pokémon with a distinctly dinosaur-like appearance, most notably resembling creatures from the Ceratopsidae family like Triceratops combined with characteristics of the armored Ankylosaurus. Its body is encased in a crusty, highly durable gray exoskeleton adorned with plates of silver armor that reflect its Steel-type nature. The creature's most distinctive features are the two pairs of holes on its head, with curved, pointed horns protruding from the foremost holes—these horns are sharp enough to perforate thick iron sheets and grow longer throughout the Pokémon's lifetime, serving as a natural indicator of its age. Its forehead plating extends past its upper jaw in a small point, while sky-blue eyes and nostril-like holes mark its face. The body is further reinforced with gray-silver bands on its arms and legs, wide blunt spikes on its shoulders, and claws on both its hands and feet. Aggron's internal composition contains a high concentration of iron, making it a truly metallic creature. The Pokédex notes that the gouges and scars accumulated on Aggron's armor are worn with pride as mementos from its countless battles, with older Aggron bearing more extensive battle damage as proof of their combative history.
Aggron maintains a perfectly balanced gender ratio of 50% male and 50% female, allowing for equal breeding opportunities regardless of the trainer's preference. The species belongs to the Monster egg group, which encompasses a diverse collection of Pokémon typically characterized by their size, power, and often dinosaurian or beast-like appearance. The breeding process results in an Aron, the first stage of the evolutionary line, with an egg hatch counter of 35 cycles, translating to approximately 8,739 to 8,995 steps for the egg to hatch. Aggron exhibits a slow growth rate, meaning it requires substantially more experience points to level up compared to Pokémon with medium or fast growth rates, making the journey from Aron through Lairon to Aggron a lengthy but rewarding endeavor. The base happiness of Aggron is notably low at 35, reflecting the species' naturally aggressive and independent temperament. This lower happiness value makes raising Aggron from an egg or catching one in the wild somewhat more challenging for trainers seeking to quickly build affection, though consistent care and positive interactions gradually increase the Pokémon's loyalty and happiness over time.

Aggron evolves from Lairon when the latter reaches level 42, completing the three-stage evolutionary line that begins with Aron. This final evolution grants Aggron its Steel and Rock typing along with a significant boost to its Attack stat (110) and especially its Defense stat (180), transforming it into one of the most defensively formidable Pokémon in the Hoenn region and beyond. In Generation VI, Aggron gained the ability to Mega Evolve using the Aggronite, transforming into Mega Aggron and increasing its height to 2.2 meters while gaining additional weight at 395 kilograms. Mega Aggron's most significant change is the loss of its Rock typing, becoming a pure Steel-type Pokémon—a unique distinction as it is the only Mega Evolution to lose a type upon transformation. This Mega Evolution further enhances Aggron's already impressive Defense stat to an extraordinary 230, while its Attack increases to 140, creating an even more powerful tank-like presence in battle. Mega Aggron's signature ability changes to Filter, which reduces the damage from super-effective moves, further cementing its role as an unkillable defensive wall. The Mega Evolution physically manifests as a more imposing, armor-plated version with enhanced proportions that emphasize its role as an impenetrable fortress.

Aggron exhibits fiercely territorial behavior, claiming an entire mountain as its exclusive domain and mercilessly attacking anything that dares to violate its environment. According to multiple Pokédex entries, this Pokémon vigilantly patrols its territory at all times, making it an exceptionally dangerous adversary for those who trespass. However, Aggron displays a surprisingly protective and nurturing side regarding its mountain habitat—if its territory is ravaged by a landslide or fire, Aggron will haul topsoil to damaged areas, plant trees, and meticulously restore its environment to its former beauty. This combination of aggressive territorial defense and environmental stewardship reveals a complex personality focused on preserving its claimed domain. While seeking iron for sustenance, Aggron digs tunnels by breaking through bedrock with its steel horns, demonstrating both its strength and its dietary requirements. The species maintains lower-than-average base happiness at 35, reflecting its aggressive and independent nature, though this does not diminish its capacity for loyalty to trainers who earn its respect.

Long ago, there was a king who wore a helmet meant to resemble the head of an Aggron. He was trying to channel the Pokémon’s strength.
The Japanese name Bossgodora combines 'Boss,' suggesting leadership and dominance, with 'Godora,' likely derived from 'godzilla' or similar powerful creatures, emphasizing Aggron's imposing nature and territorial authority. The English name 'Aggron' itself appears to be a portmanteau of 'aggressive' and 'iron,' perfectly capturing the Pokémon's temperamental personality combined with its metallic composition. The design draws inspiration from multiple prehistoric creatures, primarily the Triceratops from the Ceratopsidae family, evident in the distinctive paired horns and dinosaur-like body structure. Additionally, elements of Ankylosaurus are incorporated through the armor plating and the protective, heavily-fortified aesthetic. The silver armor plates and steel-gray coloration directly reflect its Steel typing, while the rocky, weathered appearance of its exoskeleton complements its Rock typing. Historical references appear in the Pokédex entry mentioning a king who wore a helmet designed to resemble Aggron's head, attempting to channel the Pokémon's legendary strength and territorial power. This cultural reference adds depth to Aggron's design, positioning it not merely as a creature but as an entity worthy of emulation by human leaders seeking to embody its formidable qualities.

In competitive Pokémon battling, Aggron serves as one of the premier defensive walls available to trainers, with its exceptional Defense stat of 180 allowing it to withstand even super-effective physical attacks. The Sturdy ability, which prevents Aggron from being knocked out in a single hit and instead leaves it with 1 HP, combined with its Rock Head ability that negates recoil damage from moves like Double-Edge, makes Aggron an exceptionally durable tank in battle. Its hidden ability, Heavy Metal, doubles the Pokémon's weight, which can be strategically utilized or detrimental depending on the competitive format and opponent team composition. With a relatively modest Attack stat of 110 and particularly weak Special Attack and Special Defense stats of 60 each, Aggron functions best as a physical wall that uses moves emphasizing its bulk rather than offensive power, typically running a moveset focused on defense, status moves, or physical coverage moves. The low Speed stat of 50 means Aggron almost always moves last in turn order, but this is often irrelevant given its defensive prowess. Mega Aggron further elevates Aggron's competitive viability by increasing its Attack to 140, Defense to an unprecedented 230, and providing the Filter ability that reduces damage from super-effective attacks, making it capable of surviving hits that would obliterate most other Pokémon.
Aggron is a steel and rock type Pokemon.
Aggron evolved from lairon that evolved from aron.
Aggron is weak to fighting, ground and water type moves.
Aggron can be found in poni plains (alola).
Aggron has maintained a consistent presence in Pokémon popular culture since its introduction in Generation III, establishing itself as an iconic representation of raw defensive power and territorial majesty. The Pokédex entry referencing a historical king who wore a helmet resembling Aggron's head to channel its strength has inspired numerous fan theories and creative interpretations exploring the connection between leadership, power, and the natural world. In the anime series, Aggron has appeared in various capacities, though it remains less prominently featured than some other Pokémon, yet its appearances consistently portray it as a formidable and awe-inspiring creature worthy of respect. The species has generated considerable fan art and discussions within the Pokémon community, particularly among competitive players and those appreciating defensive-oriented team compositions. Trading card game representations of Aggron have also contributed to its cultural significance, with various Aggron cards released across multiple sets, some featuring impressive artwork that emphasizes the Pokémon's imposing stature and armored appearance. Aggron's role as an environmental steward in the Pokédex, actively restoring its habitat after damage, has resonated with environmentally-conscious fans and highlighted a more nuanced characterization beyond its aggressive territorial nature. The introduction of Mega Aggron further revitalized interest in the species within competitive circles and general fandom discussions.
Aggron's availability varies significantly across different Pokémon games, though it has been featured in most major releases since Generation III. In the original Ruby and Sapphire games, Aggron served as a native Pokémon of the Hoenn region with the local Pokédex number 0072, making it relatively accessible to players progressing through the main campaign. Subsequent generations have included Aggron in various games, including Black 2 and White 2 (local number 0168), X and Y (local number 0101 in Mountain Kalos), Omega Ruby and Alpha Sapphire (local number 0074), and more recent titles like The Crown Tundra expansion (local number 0193). The catch rate of 45 represents a moderate difficulty in capturing Aggron in the wild, requiring somewhat more effort than common Pokémon but considerably less than legendary creatures. Base experience yield of 239 points per defeated Aggron provides reasonable experience progression for trainers battling them in the wild or during trainer encounters. Additionally, players can obtain Aron at lower levels in many games, allowing them to raise and evolve the creature through natural progression without necessarily encountering a wild Aggron. The Aggronite Mega Stone, required for Mega Evolution in Generation VI onward, is typically distributed through postgame content or special events, ensuring that players who complete the main story can access Aggron's full potential through its Mega Evolution form.
