>>43286317Some of Pikachu's speech is consistent enough that it seems that some phrases actually mean something. (In Stealing The Conversation, Team Rocket refers to this language as "PikaSpeak," however, this most likely isn't official.) For instance,
Pikachu always uses "Pikapi" when referring to Ash (notice that it sounds somewhat similar to "Satoshi"). Other speech includes:
Pi-Kachu: He says this during the sponsor spots in the original Japanese.
Pikachu-Pi: Kasumi (Misty)
Pika-Chu: Takeshi (Brock)
Pikaka: Hikari (Dawn)
PiPiPi: Togepy (Togepi) shuriken: (found this one very obvious back in the day and was really the only one i thought had actual meaning.)
PikakaPika: Fushigidane (Bulbasaur)
PikaPika: Zenigame (Squirtle) or Mukuhawk (Staraptor) or Goukazaru (Infernape) or Gamagaru (Palpitoad)
Pi-kachu: Pochama (Piplup)
PiPi-kachu: Team Rocket (Team Rocket).
Pi-Pikachu: Get da ze! He says this after Ash wins a badge, catches a new Pokémon or anything similar.
