White / Y / Alpha Sapphire	They attach themselves to cave ceilings, firing steel spikes at targets passing beneath them.
Black 2 / White 2 / X / Omega Ruby	By swinging around its three spiky feelers and shooting spikes, it can obliterate an opponent.

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.
