Friendship

Happiness is a measurement of how much a Pok?mon loves its Trainer and enjoys being in their care. Happiness affects the evolution of certain Pok?mon, the power of Return and Frustration, and the availability of a few in-game items and ribbons. Certain events increase a Pok?mon's happiness (gaining a level, walking 256 steps) or decrease it (fainting, using herbal medicine).

Happiness was introduced in Pokémon Yellow for the player's starting Pikachu only, and expanded to cover all Pok?mon in Generation II.

Generation I

A prototype of the happiness system used by later games was introduced in Pokémon Yellow, the last main series game of Generation I. Like the later system, its value ranged between 0 and 255 inclusive; however, this value was only applied to the Pikachu the player started with.

Pikachu at maximum happiness

Unlike later games, since Pikachu is outside of its Pok? Ball, the player can turn and look at it at any time as it follows him around the overworld. Pikachu will then indicate its happiness in a small window that appears. At maximum happiness, Pikachu will jump up and down before the window appears.

Like later games, Pikachu's happiness will rise when it gains a level. If its Trainer uses an item on Pikachu, its happiness will also rise, even if it is an item that has no effect on Pikachu (such as a Potion at full HP). In this manner, Pikachu is much easier to make happy than Pok?mon in future generations.

Pikachu's happiness drops if it is put into Bill's PC or faints. Trading it to another game will reset its happiness to 0.

Happiness is not recorded for any other Pok?mon in Generation I, and the happiness of Pikachu does not affect much: the only real effect it has is whether Melanie will give Bulbasaur away in Cerulean City, which she will only do if Pikachu's happiness is 147 or higher.

Happiness	0 to 99	100 to 199	200 to MAX
Event	Change
Gaining a level	+5	+3	+2
Using an item	+5	+3	+2
Challenging a Gym Leader	+3	+2	+1
Depositing in the PC	-3	-3	-5
Fainting	-1	-1	-1

Generation II

In Generation II, the happiness system became fully implemented, building on the system used in Yellow by tracking the happiness of every Pok?mon owned by the Trainer. Like before, it is a single byte with a value between 0 and 255.

Happiness is set when a Pok?mon is brought under a Trainer's control: that is, it is 70 when a Pok?mon is captured from the wild, and reset to 70 when a Pok?mon is traded from another game. When a Pok?mon is hatched from an egg, its value is set to 120. If a Pok?mon is captured in a Friend Ball, rather than any other kind, its happiness is set to 200 instead.

Another function was given to happiness in Generation II: the evolution of certain Pok?mon, which has continued until the present as each generation introduces new Pok?mon which evolve through happiness. Happiness-based evolutions occur when a Pok?mon's happiness is 220 or higher.

Unlike in Generation I, happiness will not increase if an item that cannot be used is used on a Pok?mon: for example, using an HP Up on a Quilava which already has the maximum HP it can have will not result in raised happiness.

Happiness	0 to 99	100 to 199	200 to MAX
Event	Change
Walking 512 steps	+1*
Grooming, Daisy	+3
Grooming, older haircut brother	+5	+3	+1
Grooming, younger haircut brother	+10	+3	+1
Using vitamins	+5	+3	+2
Gaining a level	+5	+3	+2

Fainting	-1
Using EnergyPowder	-5
Using Heal Powder	-5
Using Energy Root	-10
Using Revival Herb	-15
Trading to another game	Reset to 70

However, some things, though frequently reported, aren't part of the Generation II modifier. The following are actions that do not affect a Pok?mon's happiness, either positively or negatively:

Putting a Pok?mon in Bill's PC
Healing a Pok?mon when weak and injured
Giving a Pok?mon a hold item
Using a Pok?mon in battles
Winning battles with a Pok?mon
Letting a Pok?mon's HP fall to critical status
Letting the player's Pok?mon get a status condition like Paralysis
Walking when the player's Pok?mon has a status condition

Generation III

Happiness in Generation III works much the same as before, with two additional happiness-boosting mechanics. If a Pok?mon is caught in a Luxury Ball or is holding a Soothe Bell, all happiness-raising events will increase the Pok?mon's happiness by one point more; happiness-lowering events are not affected. These effects stack on each other, meaning a Pok?mon in a Luxury Ball holding a Soothe Bell gets two additional points per event.

Pok?mon now have a base happiness per species; however, most catchable Pok?mon have the standard 70 points as their starting level.

Happiness	0 to 99	100 to 199	200 to MAX

Walking 256 steps	+1
Grooming, Daisy*	+3	+3	+2

Pok?mon FireRed and LeafGreen

In Pokémon FireRed and LeafGreen, the player can know the happiness level of his/her Pok?mon through the scene which appears after the player uses an item on the Pok?mon. The Pok?mon will either move towards the screen or not move at all. If the Pok?mon does not move, then its happiness level is neutral. The happiness level of the Pok?mon can be indicated by looking at how near the Pok?mon goes to the player. The nearer the Pok?mon moves towards the screen the higher its happiness level and the more it likes its Trainer.

Generation IV

Happiness in Generation IV is much the same as it is in Generation III, though the conditions are altered slightly. The Luxury Ball now causes a Pok?mon to gain a separate boost in happiness when they level up and while walking compared to Pok?mon in other Balls.

Dr. Footstep, the sole resident of the Footstep House on Route 213, will give a Pok?mon with maximum happiness a ribbon.

In HeartGold and SoulSilver, the player can gauge their Pok?mon's happiness based on the phrase that appears when they are spoken to outside of their Pok? Ball.

Daisy makes a return in HeartGold and SoulSilver. Visiting her in Pallet Town will let her groom one of the player's Pok?mon between 15:00 and 16:00 every day, increasing its happiness.

The Haircut brothers also make a return in HeartGold and SoulSilver. The player can visit them on any day of the week besides Monday to give one of their Pok?mon a boost in happiness.

In the table below, the first and second values separated by slashes show the changes for most Pok? Balls and Luxury Balls, respectively. Note that holding a Soothe Bell will apply a multiplier of 1.5 (rounding down) to only positive changes and that use of Luxury Balls will not reduce the effects of negative changes.

Generation V

Happiness is very much the same in Generation V as it was in Generation IV. As far as it has been tested, happiness conditions and related items are much the same, with the main differences being in what NPCs will rate and measure happiness. A lady in Nacrene City will rate the happiness of the player's Pok?mon. Another lady, in the Pok?mon Fan Club located in Icirrus City will also rate the happiness of the player's Pok?mon. A third lady in Castelia City will massage one of your Pok?mon per day, raising its happiness. She is located in the first building on the left side of Castelia Street.

The happiness statistics appear to have not changed much since Generation IV. Note that holding a Soothe Bell will still apply a multiplier of 1.5 (rounding down) to only positive changes and that use of Luxury Balls will not reduce the effects of negative changes.

Happiness raters

Happiness raters are NPCs that will indicate the happiness of the first Pok?mon in the player's party when spoken to. Some will give away certain items depending on the happiness, while others just tell the player how happy the Pok?mon is.

Statement	Happiness
"It is super friendly to you! I'm a bit jealous!"	250-255
"It is quite friendly to you! You must be a kind person!"	200-249
"It's friendly toward you. It looks sort of happy."	150-199
"It's quite cute."	100-149
"You should treat it better. It's not used to you."	50-99
"It doesn't seem to like you at all. It looks mean."	0-49

In spin-off games

Pok?mon Ranger: Shadows of Almia

Two Pok?mon in a Happy Mood

Happiness also has an effect in the second Ranger game. Partner Pok?mon can have the condition of Fine, Happy, or Very Happy. When it is in a Happy Mood, musical notes come out. Black musical notes come out of it when it is happy. Multicolored musical notes come out when it is very happy. This may happen whether it is with the player. This state of mind increases the speed the Partner Gauge fills up due to more Partner Energy being given.
