Best or worst pony means nothing to me. It’s just a petty myth created by the butthurted masses.

Sorry Flutters, but you’ve been voted off the Mane 6… well, “Mane 5.”

What?Most people claim her worst pony because she has a boring personality?All because of that?  
There isn’t anyone here that thinks she’s a bad friend and fails hard at being kind?
 
If she was just boring i wouldn’t even hate her.

Nope. There is no “worst pony”. There is only “worst human” and that title goes to anyone who seriously considers any of the mane 6 “worst pony”. In that case, there are many “worst humans”, unfortunately.

I made a .gif once
There isn’t actually a worst or best pony, because there’s no objective way to discern that.
 
So don’t let it get to you. Even when I say Rainbow Dash is best.
 
@Princess♠Molestia  
Sheesh, that’s even more than Mike Nelson.

Funny how Fluttershy was very popular in season one but tanked in the later seasons due to the reduancy of her personality.

You have the power to fix that, Fluttershy.

There is no such thing as worst or best pony Fluttershy, it’s a delusion created by butthurt people.
