have you seen this page in the scrapped monsters it reads Rainbow Mothra is depicted on the box art. It is unknown if he was to be truly included or it was merely an art error. During an interview for Godzilla: Unleashed Simon Strange mentions Rebirth of Mothra characters would not be allowed due to Toho considering it a separate series.
