Started watching a new “Seven Deadly Sins” (because that theme will never get old /sarcasm) anime and it got me thinking about the Mane 7 (or whatever we’re calling the Mane 6 plus Sunset instead of Spike) as possible incarnations of said Sins.
Twilight as Wrath
Applejack as Greed
Rarity as Vanity
Fluttershy as Lust
Pinkie Pie as Gluttony
Rainbow Dash as Sloth
Sunset Shimmer as Envy
The justification for my choices are as follows:
Twilight is the angriest out of the group and also the most prone to (intentional) violence, especially against other sapient beings. Time and again throughout the series, her solution to many problems has been to attack them (after, of course, some provocation, as wrath is reactionary rather than initial, which is simply aggression).
Applejack started off nearly as mercenary as the griffons. She only cared about the Gala because of the potential money she thought she would make there.
Rarity is a fashionista by trade. There is no enterprise more vain. Not even the media.
Fluttershy is xenophilic. Of course, the true manifestation of her sin stems from her fans, but that seems to me to be how sin-level lust works.
Pinkie Pie should not have to be explained.
Rainbow Dash is the tricky one, given that her dedication to her ambitions had given her the power to achieve them, but you have to look at her character. RD is actually incredibly lazy and frequently found napping or otherwise lounging.
Sunset Shimmer was literally a Green-Eyed Monster in the first movie. She was motivated by a desire to be as powerful as Celestia to the point where she forgot why she wanted that power in the first place.
I also think that Trixie should have been Rarity’s primary antagonist rather than Twilight’s. The former two both use the stage as their field of choice, and have similar-looking character flaws. Also, whenever Trixie attacked Rarity, it was with something that is known only to the two of them to be un-fashionable. Like Applejack said in 7-9, most ponies don’t have the slightest grasp of the fashion world, and if she was truly ignorant, Trixie could have just as easily accidentally dressed up Rarity in an ensemble that was “avant-garde”, which would typically look just as terrible to a fashion-blind pony as the actually terrible designs. But she never made that mistake, and Trixie is prone to mistakes.
Just some thoughts.
