Crossover ship?

Gary’s blastoise lost to Ash’s charizard  
Shimmer’s demon lost to Sparkle’s friendship.

You are now Equestria’s newest princess. You thought everything was gonna be just fine. Just when your guards is down, guess who steals your magic crown and challenges you to a prom? SUNSET MOTHERUCKING SHIMMER, that’s who.
 
You are Trixie Lulamoon. For the past three years, you’ve been set up as Twilight Sparkle’s rival. But then who decides to show up, slap you in the face, steal your position, gets paired up with Twilight in hundreds of fanfics within days, and even replaces you as Sethisto’s waifu, while you are forgotten? SUNSET MOTHERFUCKING SHIMMER is just that awesome.
 
Sunset has just finishing owning your nerdy, scrawny butt in the prom. She goes up to the stage to accept her prom queen crown. She’s tired. She trips and falls off the stage, landing on her head and lapsing into a coma. Why? Because not even SUNSET MOTHERFUCKING SHIMMER is safe from SUNSET MOTHERFUCKING SHIMMER.

 
I’m gonna assume this was what caused a falling out between Shimmer and Celestia.

Perfect couple

SUNSET WAS HERE  
TWILIGHT IS A LOSER

Fuck! We will forever be unable to ignore her girth

Sunset Motherfucking Shimmer, anyone?

And then they were shipped.

You know who actually she reminds me of? Scanty and Kneesocks.

Sunset Shimmer really is shaping up to be the best part of this mess. She’s giving of a lot of “over the top high school bitch caricature” vibes and I am loving them.

Gary Fucking Oak.
