THE EVOLUTION ENIGMA

In GS there are two new ways to evolve your Pokémon; through firendship and through trading them to another GS pak when they are equipped with a particular item. There are also the old ways, like evolving your Pokémon through experiance, trading and stones. I have created charts to show which Pokémon you evolve in what way.

HOW TO GET YOUR POKÉMON TO LIKE YOU
DO
  • Keep them in your party for a long time. This doesn't mean they have to fight.
  • Use items on them and equip them with an item too
  • Give them haircuts in Goldenrod (every day but Monday) and let Gary's sister groom them (every day at 3-4 PM)
DON'T
  • Make the Pokémon take bitter medicines
  • Trade it away to another person (unfortunately, you must do this with the guys you need to evolve like that)
  • Let it faint over and over
  • Let it get really weak in HP over and over
