Why is Rarity Percy?

I’ll show them!

Rainbow Dash is just Gordon with a blue face (and white wheels).

And Glynn (from The Adventure Begins).

Don’t forget Skarloey

…Rarity’s a purple caterpillar with black stripes. >>

“Fancy a really useful blue engine like Rainbow Dash becoming a disgrace the Sun Controller’s railway!”

I always figured Pinkie would be more like Percy.

GORDON WHAT’S A RARITY

the facial expressions are what really make this image.
 
Fluttershy: [yaying internally]  
Dash thinking to herself: Man, I can’t believe I’m a freakin train…  
and Rarity …I’m actually not sure what’s going on with Rarity.

This gives “the iron horse” a whole new meaning.

Watching Thomas and the Magic Railroad right now. Sure, the movie is a bit too “mature” for young kids and is super Americanized, but I still love the hell out of it. The original script is a lot better though.

the swag train takes no breaks  

Rainbow Dash is the express train engine while Fluttershy and Rarity are the switch yard engines. Makes sense.

“Rainbow was rather cross, and thought of a devious, evil plot to disrail Fluttertrain.”
