Sword Scout Vs RED...
AppleJack vs. ApplePills: AppleJack, hands down. ApplePills forsook the increased physical strength (gained from years of Apple-Bucking) she had as AppleJack to focus on her addiction.
Pinkie Pie vs. Pinkis Cupcake: All depends on whether Pinkie Pie's unpredictability can tire out Pinkis Cupcake before the poor party-lover gets eaten.
Rainbow Dash vs. Rainbine: Again, it all depends, but I'm putting my bet on R.D., since Rainbine has neither (to the best of my knowledge) had to fire on a moving target, let alone one that moves as fast as Rainbow Dash can fly, nor has she really exercised her speed since she became Rainbine.
Rarity vs. RariFruit: Depends on whether or not Rarity would be willing to exploit RariFruit's obsession.
Fluttershy vs. Fluttershout: Hate to do it, but I'd have to put my bet on Fluttershout, because Fluttershy's only hope is that there's still some of her left in Fluttershout's psyche.
Brutalight: I'm sorry, you can't have your body back. It's MINE now...
twilight vs. brutalight- brutatlight: brutalight wins of course, she can conjure up swords
applejack vs. applepills- applepills: is applepills has pillz, she is ivincible
rainbow vs. rainbine- rainbine: she has guns
pinkie vs. pinkis- pinkis: she is a cannibal
fluttershy vs. fluttershout- fluttershout: no contest
rarity vs. rarifruit- tie: I have no idea, YOU DECIDE
