Ok I waaaaaas just gonna make her an OC but no joke when the idea for her popped into my head I was like Oh No Vapor Trail Similarities. Plus like I had multiple people point it out to me afterwords >>;;;;;; OOPSIES  
It was honestly gonna come down to her color scheme to determine if she was gonna be a Next Gen or not and HERE WE ARE
 
She was initially made on the basis of me fleshing out an underdeveloped plot point for one of my Other OCs but now she is an even bigger PLOT POINT for her younger sister I have yet to design. uwu I GOT AN IDEA FOR A SIDE ARC FINALLY AY E
 
SHE’S A VAPOR TRAIL X SKY STINGER IF IT ISNT OBVIOUS
 
I wanted her to be swan-themed and kinda noodly in comparison to Kera: fav.me/d9z07w7 (A really old ref plz forgiv)  
Also intended for their color schemes to contrast Significantly
 
The main thing to know about Willow is shes hecking Dead™  
Died in a horrible stunt accident involving her wingpony, Kerosene Skyflower OOPS
 
She was training at the Wonderbolts academy before she died obviously  
She’s the firstborn of two to Vapor Trail and Sky Stinger
 
Willow was very lighthearted and gentle to most, she aimed for greatness like that of her parents and was successful at achieving it. She was seen to many as the perfect prodigy to two Wonderbolt vets.
 
Willow wasn’t a fast flier, but she was precise given her somewhat abnormally large wings.
 
Willow was paired with Kera as Lead Pony in an attempt to level out Kera’s hotheadedness.
