Hyper Training is a modern-game system that lets eligible Pokémon treat selected IVs as if they were maximized for battle calculations. It is useful for improving a Pokémon you already own rather than breeding a new one. The underlying original IV values may remain unchanged for certain breeding-related purposes, so Hyper Training is not always a substitute for breeding if you plan to pass IVs to offspring. Requirements, level thresholds, and items vary by game. For normal play, Hyper Training is optional; for competitive teams, it can save substantial time. Check the game’s rules before spending rare resources.
