=Generation I=
In Generation I, Pokémon Yellow introduced a prototype version of the Happiness value that would later be used in future generations.  Pikachu will follow your main character throughout the game.  You can turn and look at Pikachu at any time to gauge it's loyalty to you.  It's expression will range from indifference to estatic depending on how happy it is.  At it's peak, Pikachu will jump up and down.

Pikachu's Happiness level will rise when it gains a level.

It will drop when it is put into [[Bill's PC]], or faints.  Trading it will reset it's Happiness rating.

It is relatively easy to make Pikachu happy compared to Pokémon in future generations.

Happiness is not recorded for any other Pokémon in Generation I, aside from Pokémon Yellow's starter Pikachu.

=Generation II=
Pending.
=Generation III=
Happiness in Generation III is a value between 0 and 255. Wild Pokémon have their own base happiness, which is typically 70 (about 27%) for non-legendary first stage Pokémon, but not always. If a Pokémon hatches from an egg, its initial happiness ignores the base happiness value and is set to 120 (about 47%). When a Pokémon is still in its egg, its happiness value is ignored (as there are no aspects in the game that apply happiness to eggs) and the happiness value is used as a decrementing step value that triggers the egg hatch when it reaches zero.

Happiness evolutions occur when happiness reaches 220 (about 86%).

<!-- todo: put in the game's happiness modifiers. Be sure to include exact values (for example, emerald berries increase it by 5) -->
