Pokédex entries

What each game says about it, in the games' own words.

Ruby	This POKéMON has a body of steel. To make its body, ARON feeds on iron ore that it digs from mountains. Occasionally, it causes major trouble by eating bridges and rails.
Sapphire	ARON has a body of steel. With one all-out charge, this POKéMON can demolish even a heavy dump truck. The destroyed dump truck then becomes a handy meal for the POKéMON.
Emerald	A POKéMON that is clad in steel armor. A new suit of armor is made when it evolves. The old, discarded armor is salvaged as metal for making iron products.
FireRed / LeafGreen	It eats iron to build its steel body. It is a pest that descends from mountains to eat bridges and train tracks.
Diamond / Pearl / Platinum / Black / White / X	It usually lives deep in mountains. However, hunger may drive it to eat railroad tracks and cars.
HeartGold / SoulSilver / Y	When it evolves, it sheds the steel carapace that covered its whole body and develops a new one.
Black 2 / White 2	In order to build up its steel body, it eats iron ore. This pesky Pokémon is known to eat railroad tracks.
Omega Ruby	This Pokémon has a body of steel. To make its body, Aron feeds on iron ore that it digs from mountains. Occasionally, it causes major trouble by eating bridges and rails.
Alpha Sapphire	Aron has a body of steel. With one all-out charge, this Pokémon can demolish even a heavy dump truck. The destroyed dump truck then becomes a handy meal for the Pokémon.

Official data here is present-day reference data from PokéAPI, not a snapshot of any one game's era — the Fairy type and hidden abilities arrived partway through the series, so a difference against an older game can belong to the series rather than to that ROM hack.
