When creating a perfect competitive pokemon, some attributes need to be correct on hatch/catch while others can be improved. This generation makes it easier than ever to turn a pokemon into a perfect pokemon.

Lets say I have a pokemon that, because of shininess, sentimental value, or other reasons, I want to use rather than breeding something better. It has the wrong nature, IVs, moves, ability, and just about everything.

What can be improved in game? What cannot be?

1 Answer 1


The only things that cannot be changed are:

  • Any specific IVs that aren't 31, such as wanting 0 speed for Trick Room
  • Any moves that are exclusive to special events (which SwSh does not have yet)
  • The gender of the pokémon, if relevant to the species
  • The pokéball it is stored in
  • Anything that relies on the PID (Spinda spots, whether Wurmple evolves into Silcoon or Cascoon, etc.)
  • Pure flavour information such as characteristic ("proud of its power", etc), time/location met, real world location (used for vivillon formes), shininess

Everything else can be modified.

  • IVs can be maximized to 31 through bottle caps and hyper training (requires level 100)
  • Natures can be changed through the new mints
  • The ability capsule can change an ability from "slot 1" to "slot 2" and vice versa
  • Egg moves can now be transferred to pokemon of the same species through the daycare
  • EVs can be reduced by EV reducing berries or reset entirely by an NPC on the Isle of Armor and retrained in the desired stats
  • The Isle of Armor DLC includes a way to give or take away from a specific pokemon the ability to Gigantamax
  • The Crown Tundra DLC includes a way to give a Pokémon its Hidden Ability (although it cannot revert a Hidden Ability back to a regular one)

It can also be assumed that any Pokémon that could only obtain a certain move in a previous game through a move tutor or something won't be able to pass it across once Home is out, but I'm listing that separately since it's unconfirmed.

  • Can you please update this with the new information from the release of Home and Isle of Armor? Apparently I'm not allowed to. Jul 23, 2020 at 5:33
  • To reviewers: if new DLC/patches includes new ways to change a pokémon's attributes, it's fine if they get edited in here.
