Pokédex entries

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

X / Omega Ruby	It creates throwing stars out of compressed water. When it spins them and throws them at high speed, these stars can split metal in two.
Y / Alpha Sapphire	It appears and vanishes with a ninja’s grace. It toys with its enemies using swift movements, while slicing them with throwing stars of sharpest water.

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.
