Miitopia is a Pretty Bare-Bones game, so i'm going to add a bit more dark to it. This is my fan theory about how the Fab Fairies are actually evil. There is even some proof with why the Green-Eyed Lady is so Jealous at them and stuff
Those Fairies act good against the Hero, but that's mainly because they sense his power, and don't want to get a whipping from it. They are not a part of the Dark Lord, however they can still be evil. And perhaps the only reason why the Youngest does quest is for something sweet to munch on, and knowing the hero's great power, she asks him to help her.
(Also, interestingly enough, they don't have wands. Not sure why, but don't fairies generally have wands in some myths?)
Other than the first time you meet the Retreat, One of the fairies always protects the retreat. This is probably to keep the Elves Brainwashed from their magic.
Now, here is a bit of past stuff to add in the evilness.
Perhaps the Green-Eyed Lady was once popular before the Fairies invaded. She was the only one to not get brainwashed by them, and hates them because of that, and Jealousy too.
Even in Mythology, Fairies are depicted as Wicked Creatures and they decept humans and bind them into servitude for the rest of their lives. It is the Realm of the Fey after all. Perhaps they do the same to Elves.
Also, the Realm of the Fey might've even had previous creatures in it, like Fairies, Brownies, Pixies, and more. And I'm curious; what happened to those Fey? Maybe the Fab Fairies are much darker than we think. Perhaps they are actually murderers and killed off the other fey, and all they have left are the Elves, slowly killing them too.
Let that sink in for a moment.
Now, you might question "The Middle Fab Fairy would never do that!", but what if I told you that The Middle Fab Fairy maybe pretends to be nice and Pacifist (Or maybe she has to do it because of her sister)? Heck, maybe ALL 3 Fairies are hiding their true personality.
Now, you won't be thinking the "Fab" Fairies the same way again.
Also, is it just me or is the Prince from a Nearby Land's Mom is dead?
Do you think my theory is true?
