@sigh  
Pinkie may actually work better as Nepeta than Gamzee, given her chipper-to-crazy ratio. Of course, then we have to find somepony else to serve as the murderclown. I propose Berry Punch. She’s the resident substance abuser, after all.

Nepeta as Applejack? Hmmm… it’s hard to buy but then again there really isn’t anyone else to match her up with.

my Troll = Pony lineup is:
 
Karkat Vantas = Lily Blossom (they both have red blood and two eyes)  
Aradia Megido = Doctor Whooves (very smart and connection to time)  
Tavros Nitram = Fluttershy (shy and love animals)  
Sollux Captor = Derpy Hooves (“different” eyes and somewhat yellow)  
Nepeta Leijon = Applejack (hardworking but cute and gets less screentime)  
Kanaya Maryam = Rarity (fashionista)  
Terezi Pyrope = Rainbow Dash (tomboyish that love colors)  
Vriska Serket = Trixie Lulamoon (pseudo-bitches)  
Equius Zahhak = Big Macintosh (for the STRONG)  
Gamzee Makara = Pinkie Pie (chill-crazy)  
Eridan Ampora = Twilight Sparkle (magician)  
Feferi Peixes = Cheerilee (cheery and slightly purple-pink)

Norman and Sunset? As Tavros and Vriska? Yeah I could see it.

“I’m going ghost!”

Pinkamena: “h0nk”

Pinkie is best/worst rascally clown.

Now…explode.
