Actually, that reminds me of how one of the White Wolf RPG systems has each player pick a sin and a virtue for their character, which ends up creating some surprisingly well-rounded personalities. If you want to “disguise” each representative’s sin (or make them seem like decent people/ponies/whatever at first), than that could be a way of doing it: focusing on a virtue for each and gradually hint that they’re really a villainous glutton or whatever.
My current fanfic project:
Transformers: Friendship is Magic, an AU which re-imagines the Mane 6 and company as giant transforming alien robots in sort of a mash-up version of the FIM pilot 2-parter with various Transformers series.
The one feature that I’m a little apprehensive about is that Sweetie Drops/Bon Bon, Ditzy Doo/Derpy, and Fluttershy (in addition to several other ponies) are going to be Decepticons. In a reference to her “kindness” trial with the manticore in the FIM pilot, Fluttershy will try to defuse a fight and end up empathizing and siding with the Mane Autobots. Most of the rest, though, won’t be switching sides anytime soon.
I hate to use TV Tropes parlance, but I worry casting minor background characters as recurring villains will come off as “Ron the Death Eater”-ish (fandom demonizing “good” characters). The idea here was that the major Decepticon players (Nightmare Moon, Sombra, Chrysalis, etc.) are
really good at exploiting the gray moralities of wartime to gain followers. Additionally, while the Mane 7 will still be a team of good guys by the end of the fanfic, I wanted to show how fractured the characters of Equestria would be in the event of an endless Transformers-style civil war, where both sides can indoctrinate their young and wartime can turn normally decent characters into monsters.
So, what do you think? Background Six et. al. as Decepticons (with some sympathetic reasons for joining them)…or should I wait until that EqG 3 movie introduces those “Shadowbolt” villains?
