Hydro Vortex (Special) is a Water-type Z-Move introduced in Generation VII. It does not have a fixed power or accuracy; instead, its power is determined by the base move from which it is converted when a Pokémon holding a Waterium Z uses a special Water-type move. The power ranges depending on the base move's strength, generally amplifying the base move's potency significantly. Hydro Vortex never misses its target, as Z-Moves bypass accuracy checks. This move is a one-time use per battle and showcases an impressive animation, making it a strategic and visually appealing choice in battles. Hydro Vortex (Special) takes advantage of the heightened power and precision mechanics unique to Z-Moves, adding substantial impact to any Water-type Pokémon's arsenal.
