The Pokémon gains Friendship from leveling up, but it's boosted if it levels up in the area where it was first met/caught. It's possible to lower a Pokémon's Friendship by having it faint in battle, giving it EnergyPowder, Heal Powder, Energy Root, or a Revival Herb. The ways to increase a Pokémon's Friendship include walking with the Pokémon in the active party, taking them to Daisy Oak in Pallet Town from 3-4 pm for a massage, giving them a Vitamin or a battle item (like an X Attack), teaching it a move from a TM, or giving it a haircut from the Haircut Brothers in the Goldenrod Tunnel. The Pokémon's current Friendship affects how much it's affected by specific actions. The Friendship mechanic was properly introduced in Gen II, where it applied to every Pokémon.
