>>25310629yeah but it's not like they would ever make the sun mascot a plant that absorbs sunlight, it's gonna need a stronger association with the sun, so it's almost certainly fire.
possibly fire/psychic, fire/fairy, fire/electric, fire/dragon, who knows
but the moon is a lot more ambiguous, they could easily go in any direction they want with fairy, dark, ghost, psychic, water, ice or even rock and it would all feel apropriate
