Not that it's ever been relevant to anyone's anything, but I've mentioned before that there was a really odd missed opportunity with Team Plasma's weird Seven Sages thing and how they have six of seven colors of the visible light spectrum accounted for, but then are awkwardly missing indigo, while Ghetsis makes a second green member... and also Ghetsis and N(atural Harmonia) have a musical theme yet the sages don't fit any kind of musical theme, you'd sort of expect a Diatonic scale since it's made up of 7 Modes...
But you know what iconic Nintendo JRPG DID have
a set of 7 mystical wise"men" type characters
themed after both the 7 color spectrum
and the 7 modes of the Diatonic scale
which was also missing an indigo member
and whose odd member out of the group serves as the game's villain?
(also who raised a weird orphan kid to be their protege and erroneously told them they were royalty?)
The Magypsies (named after the Gypsy scale) in MOTHER 3
(I will forever be mad that the Seven Sages of Team Plasma aren't wearing robes actually matching their color theme names... They aren't even shuffled around properly because the names account for Red Orange Yellow Green Blue (no indigo) and Violet, but then they're wearing Yellow, Indigo(?), Red, Black/Gray(?), Green, and Violet? No proper Blue or Orange???)
