Pokémon BlueMoon and MidnightSun Versions, codenamed Project Nova in their first incarnation, have been in development since 2006 and in that time have gone through many significant changes. What would have been the beta for the game was originally planned as a FireRed ROM hack; however, work on the hack was discontinued shortly after it began, and as such there is no actual beta version of the games. This page lists lists Pokémon, characters, and concepts considered for the game during their long history that ultimately did not make it into the final version of the games.
