Pokédex entries

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

Black	By blasting water from its hooves, it can glide across water. It excels at using leg moves while battling.
White / X / Omega Ruby	It crosses the world, running over the surfaces of oceans and rivers. It appears at scenic waterfronts.
Black 2 / White 2 / Y / Alpha Sapphire	When it is resolute, its body fills with power and it becomes swifter. Its jumps are then too fast to follow.

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.
