HAPPINESS

Introduction

A hidden value from 0 to 255 called Happiness (also known as Tameness or Friendship) is given to all Pokemon in the game, determining how well you've tamed each of your Pokemon. For most Pokemon, this value merely determines the power of Frustration (your Pokemon has a low happiness value) and Return (high happiness). For a select few Pokemon, evolution can be achieved when the happiness value is maxed out and the Pokemon gains a level after achieving max-out of happiness.

Pokemon that Evolve from Happiness

The following Pokemon evolve by happiness. When their happiness quota has reached 220 or greater, they will evolve the next time they level up with experience or by Rare Candy. The timing of this is important for certain Pokemon, as they must be levelled up during specified time.

Discovering Happiness

Base Happiness

Each time you catch, hatch or trade a Pokemon, its Happiness quota will be reset to a certain base value depending on what Pokemon it is.

Affecting Happiness Positively

There are only a certain number of ways you can affect your Pokemon's happiness, and each way has less of an effect as your Pokemon gains more happiness. Giving your Pokemon a Soothe Bell will increase the rate at which their happiness rises by 50%, and Pokemon caught with a Luxury Ball will get double the regular points when you level-up, walk, or use them in an important battle. Anyway, here are all the methods of affecting happiness:

Raising Happiness:
- Walk 256 steps with the Pokemon in your active Party. (+1 for all happiness values)
- Give the Pokemon Vitamins [HP Up, Carbos, Iron, Protein, Calcium, Zinc, PP Up] (+5 0-99, +3 100-199, +2 200-254)
- Usage in Important Battle [Gym Leaders, Elites, Champion] (+3 0-99, +2 100-199, +1 200-254)
- Level Up the Pokemon (+5 0-99, +3 100-199, +2 200-254 per level)

Affecting Happiness Negatively

I don't know why anyone would prefer their Pokemon to be unhappy instead of happy unless you want the Pokemon to hate you anyway, because Frustration is basically the same as Return, but it's much harder to maintain unhappiness, and your Pokemon don't evolve for it, either.

Decreasing Happiness:
- The Pokemon faints in battle. (-1 for all happiness values)
- Use of Energypowder (-5 for values 0-199, -10 for values 200-249)
- Use of Heal Powder (-5 for values 0-199, -10 for values 200-249)
- Use of Energy Root (-10 for values 0-199, -15 for values 200-249)
- Use of Revival Herb (-15 for values 0-199, -20 for values 200-249)
- As mentioned before, trading your Pokemon will reset its happiness to its base value, so be warned.

Myths of Happiness

There seemed to be a number of things thought to affect happiness that really don't mean anything at all in the game. Only the things mentioned above affect happiness, postively or negatively. But just in case you need things spelled out for you, the following factors do not affect happiness:
- Putting a Pokemon in the PC (Come on, would that really be fair? You can only have 6 Pokemon with you at a time.)
- Healing the Pokemon when weak and injured.
- Giving a Pokemon a hold item (Other than Soothe Bell).
- Using a Pokemon in battles (save level ups).
- Winning battles with a Pokemon (again, save for when it gains a level).
- Letting a Pokemon's HP fall to critical status (when the annoying beeper starts warbling).
- Letting your Pokemon get a status effect like Paralysis.
- Walking when your Pokemon has a status effect.

And that's basically all there is to happiness! May your Pokemon be tamed the way you want them to be tamed, and may Blissey rule the world!
