Sunny Flare and Lemon Zest are perfect foils for pinkie pie and rarity Sunny flare is a girly girl elegant girl like rarity but is kinda stuck up and doesn't have rarity's tact and sincerity and is all work and no play cuz of her stickler for rules profile in like pinkie pies all play but they are both girly but they are more different than the same. And Lemon Zest like fun like pinkie pie but is semi obnoxious about it and does go all out like Pinkie is and her pink skin is more dark peach and like Sunny Flare Lemon Zest is a drill Sargent nasty when it's called for even if it wasn't on screen. Plus all of them skate so even if you make Lemon pinkes foil or Sunny Raritys foil or vise versa even in reverse (although Sunny is more Raritys foil than she is pinkies but still cute when she's pinkies foil and Lemon Zest makes a perfect fit for a foil for both Rarity and Pinkie and Sunny Flare which I will explain in the next comment ) they will still just you know click oh and rarity and Lemon zest foils bcuz both perfectionist and want things flawless but Lemon zest is more tomboyish and is a perfectionist on the field but a fun rocker when off duty and rarity is more generous and girl and well you get the idea
