Aron opens a three-stage Steel and Rock line: it evolves into Lairon at level 32, and Lairon becomes Aggron at level 42. Sturdy lets it hang on at 1 HP through a hit that would otherwise knock it out from full health, and Rock Head spares it the recoil from moves like Double-Edge. Its hidden ability, Heavy Metal, doubles its weight, which matters for weight-based moves. Only 0.4 meters tall, it still weighs 60 kilograms.
A whole colony of Aron debuted in "A Hole Lotta Trouble," where Ash, May, Max, Brock and Team Rocket lost their way in a cave full of them. Steven, who has an Aron of his own, guided them through. Later, in the movie Giratina and the Sky Warrior, an Aron and its evolved relatives helped Ash's group stop a shattered glacier, and wild Aron on Iron Island were caught up in Team Galactic's scheme in "Steeling Peace of Mind!"
Aron debuted in Ruby & Sapphire (2003) on three cards: an Uncommon by Midori Harada and two Commons illustrated by Mitsuhiro Arita and Ken Sugimori. Sandstorm added an Atsuko Nishida Aron the same year. Team Magma vs Team Aqua (2004) then printed two "Team Magma's Aron" cards, both by Katsura Tabata, tying the species to the villains' side of the Hoenn story, and Double Crisis brought back a Team Magma's Aron in 2015 with art by Akira Komayama.
Since then Aron has appeared as a Common in nearly every era, from Crystal Guardians and Mysterious Treasures through HeartGold & SoulSilver, Black & White, Sun & Moon and Sword & Shield sets to Twilight Masquerade (2024). Ken Sugimori has drawn it twice, in Ruby & Sapphire and Unbroken Bonds.

Aron's most valuable cards come from the EX era, with ten of the twenty-five leading Aron cards printed there, yet the single most valuable Aron card is the Common from Mysterious Treasures, 2007. Every one of the 23 Aron cards carries a market value, covering printings from 2003 to 2024, and the ten leaders hold 84 percent of the total value. That makes Aron card value a top-heavy picture, with a short list of prints doing most of the work.
The Mysterious Treasures Common from 2007 leads the most valuable Aron cards by 2.9 times over the next card, the Uncommon from Ruby & Sapphire, 2003. Third is Team Magma's Aron, a Common from Double Crisis in 2015. Fourth and fifth are Commons from Power Keepers in 2007 and Sandstorm in 2003. Four of the five are Commons, and only the Ruby & Sapphire card carries a higher printed rarity than that.
The EX era supplies 10 of the twenty-five leading Aron cards, followed by Sword & Shield with 3, and Diamond & Pearl, HeartGold & SoulSilver, Black & White and Sun & Moon with 2 each. The newest era's leader is the Aron from Twilight Masquerade, 2024, which sits 21st overall. Vintage here means the WOTC era, and no vintage card appears in the top ten or the top twenty-five: all ten leaders and 23 of the twenty-five are modern.
Among the ten most valuable Aron cards, 9 are Commons and 1 is an Uncommon. Widening to the leading twenty-five, 22 are Commons and 1 is an Uncommon. No holo, reverse holo, 1st Edition or illustration rare print appears in either group, so Aron card value rests on plainly printed Commons from the EX, Diamond & Pearl and HeartGold & SoulSilver sets named above.
Aron ranks 725th of 1020 species with priced cards by the value of its leading card, and 572nd of 753 by the combined value of its ten leaders. In its evolution line, Aggron ranks 204th of 1020 by top card and Lairon 830th. Aron cards therefore sit in the lower half of the species ranking, and Aggron, not Aron, holds the strongest top card in the line.
