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

Black / Y / Alpha SapphireOne swing of the sword incorporated in its armor can fell an opponent. A simple glare from one of them quiets everybody.
WhitePart of the armor on its anterior legs becomes a giant sword. Its cry alone is enough to intimidate most enemies.
Black 2 / White 2 / X / Omega RubyIn the time it takes a foe to blink, it can draw and sheathe the seamitars attached to its front legs.

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.
