Some Pokemon will only evolve after you raise your friendship level to a high enough level. These include:

Eevee: Evolves into Espeon (during the day) or Umbreon (at night)
Cleffa: Evolves into Clefairy
Pichu: Evolves into Pikachu
Riolu: Evolves into Lucario
Budew: Evolves into Roselia (during the day)
Togepi: Evolves into Togetic
Azurill: Evolves into Marill
Munchlax: Evolves into Snorlax
Friendly Pokemon will also get bonus bonuses in battle, usually to help deal with difficult situations. They may ignore the pain of status, or endure the blow that would have knocked them down.
