Pokédex entries

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

RubyBAGON has a dream of one day soaring in the sky. In doomed efforts to fly, this POKéMON hurls itself off cliffs. As a result of its dives, its head has grown tough and as hard as tempered steel.
SapphireBAGON harbors a never-ending dream of one day soaring high among the clouds. As if trying to dispel its frustration over its inability to fly, this POKéMON slams its hard head against huge rocks and shatters them into pebbles.
EmeraldAlthough it is small, this POKéMON is very powerful because its body is a bundle of muscles. It launches head-butts with its ironlike skull.
FireRed / LeafGreenIts steel-hard head can shatter boulders. It longingly hopes for wings to grow so it can fly.
Diamond / Pearl / Platinum / Black / White / Black 2 / White 2 / YDreaming of one day flying, it practices by leaping off cliffs every day.
HeartGold / SoulSilverIts well-developed neck muscles and ironlike head can smash boulders into pieces.
XIts well-developed neck muscles and iron-like head can smash boulders into pieces.
Omega RubyBagon has a dream of one day soaring in the sky. In doomed efforts to fly, this Pokémon hurls itself off cliffs. As a result of its dives, its head has grown tough and as hard as tempered steel.
Alpha SapphireBagon harbors a never-ending dream of one day soaring high among the clouds. As if trying to dispel its frustration over its inability to fly, this Pokémon slams its hard head against huge rocks and shatters them into pebbles.
SunIts belief that it will be able to fly one day is apparently the influence of information carried in its genes.
MoonWith its steel-hard stone head, it headbutts indiscriminately. This is because of the stress it feels at being unable to fly.
Ultra SunWhenever it sees bird Pokémon flying through the sky, it becomes envious and smashes its surroundings to bits with headbutts.
Ultra MoonSome theories suggest that its behavior of forcefully bashing its head into things stimulates cells that affect its evolution.

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.
