Two questions, not one score
IVs help explain why two Pokémon of the same species and level can have different stats before comparable training. EVs reflect the training invested into particular stats. A Nature then applies its own stat effect. Looking only at the final number hides those separate causes.
| System | What it describes | Common way to work with it |
|---|---|---|
| IVs | Individual potential in each stat | Judge feature, breeding or Hyper Training where available |
| EVs | Training assigned to stats | Battles, vitamins and other game-specific training items |
| Nature | A stat-growth preference | Original Nature or a Mint’s effect in supported games |
Give training a job
Before optimizing, decide what the Pokémon will do. A raid attacker, a fast competitive support Pokémon and a casual story teammate can need different investments. Copying a competitive spread without the team strategy behind it is not automatically useful.
EV limits mean a Pokémon cannot maximize every stat at once. Unplanned story battles may already have added EVs, so a serious training project may require checking or resetting that investment using the options in your game.
Hyper Training is not breeding
Supported games can improve a Pokémon’s effective individual stats through Hyper Training. That does not mean those improved values become the inherited IVs passed to an Egg. Check the level requirement and the relevant NPC in the current title; these changed between games.
Let’s Go uses a different stat-boosting structure from the usual EV system. Legends games and GO also have their own systems. A six-stat training guide should name which game it covers.
You do not need perfect IVs and EVs to begin a normal adventure. Learn move categories and matchups first. Detailed training becomes more valuable when you can identify the specific battle problem those extra stats will solve.
