Friendship: Difference between revisions

In the [[core series]] games, friendship was introduced in {{game|Yellow}}, though only for the {{OBP|Pikachu|Yellow}} received at the beginning of the game. It was expanded to apply to all Pokémon starting in [[Generation II]].

Friendship affects the [[Friendship evolution|evolution of certain Pokémon]], the power of certain [[move]]s, and the availability of a few in-game [[item]]s and [[ribbon]]s. Certain activities/events can increase a Pokémon's friendship (such as gaining a [[level]] and walking a certain amount of steps), while others decrease their friendship (such as [[fainting]] and using [[herbal medicine]]).

* In {{game|Yellow}}, [[Melanie]] in [[Cerulean City]] gives the player a {{p|Bulbasaur}} if the partner {{OBP|Pikachu|Yellow}}'s friendship at least 147. Melanie will give the player this Bulbasaur even if Pikachu is not in the party or even in the game.

* Trying to release the partner {{OBP|Pikachu|Yellow}} or evolve it with a [[Thunder Stone]]{{sup/1|Y}}

Friendship was introduced in {{game|Yellow}} as a mechanic exclusively for the {{OBP|Pikachu|Yellow}} received at the beginning of the game. {{pkmn2|Outsider}} Pikachu are not affected, nor are any {{p|Raichu}} (even if Raichu was evolved from the partner Pikachu through [[trade]]). However, any {{p|Pikachu}} whose [[Original Trainer]] is the {{player}} is treated as their partner Pikachu, and all partner Pikachu share the same friendship value. This value persists if the partner Pikachu is traded, and any change in this value applies to all partner Pikachu.

When in the [[party]] and not [[fainting|fainted]], the partner Pikachu (or first partner Pikachu in the party, if there are multiple) [[Walking Pokémon|follows the player in the overworld]], and interacting with Pikachu brings up a pop-up window showing Pikachu's face. Apart from certain special events that cause special reactions, Pikachu's expression changes based on its current friendship. At maximum friendship, Pikachu jumps up and down before the window appears.
