Oh, I was just kidding about the leg!

Why don’t you ask her yourself? I mean, this series has writers. Twitter. Another modern high-tech crap.

Lightsaber

Nah, it was her older sibling. Kerfuffle pushed them out of the way just in time, but…
 

How did she lose her leg? So… She lose her leg. Therefore, now she’s without a leg.

Those can be nasty, she got of easy.

Tickle fight.

Accident at a factory.

She got stuck in the train rails.

Some random mare needed it for a scavenger hunt.
 
Let’s see who gets that reference

She had it in her luggage while flying once. It never turned up at the airport with the rest of her stuff.

She asked a different Pony how it lost it limb. Which is a crime punished by removing of a limb.

We do. Haven’t you seen the comments on all the other pictures of her? They hardly mention her leg. But it’s always fun to give a character a backstory. We do it all the time for other ponies

Applebuck duel against an apple family memeber.  
Outlawed ever since.

I actually kind of like that idea, like Scootaloo having short wings is said to be a birth defect.

Why are we even drawing attention to her prosthetic? Why can’t we just treat her like any other pony?

Freak accident with a sewing machine.

Could just be a birth defect. Although that’s not as interesting of a story

You assume she ever had 4 legs to begin with

Well, her name gives us a hint what happened…

Vietnam.

Maybe she was falling to her death when a black-colored dragon swooped down and saved her…well, most of her.
 
Get that reference?
