Quoted By:
Shuppet and Banette switched places in the Pokedex. That is why the Pokedex entry for Banette only makes sense if it were the base stage. That is why the English and Japanese and Pre-release names got shuffled around.
Kagebouzu (Pre-release) -> Juppeta (Japanese Final) -> Banette (English)
Chaaku (Pre-release) -> Kagebouzu (Japanese Final) -> Shuppet (English), *same as Japanese name of Banette*
>BANETTE generates energy for laying strong curses by sticking pins into its own body. This POKéMON was originally a pitiful plush doll that was thrown away.
