Description:
For Heavy Rain, when she flies faster than normal pegasi limits she’ll leave her own vapor trail that looks like this. In uniform, she would leave behind the iconic Wonderbolt vapor trail.
Side Note: That I always found it funny and I may be a little salty about this that Rainbow Dash and Lightning Dust are the only two pegasi shown to have their own unique vapor trails. More so on Rainbow Dash’s side when she puts on the Wonderbolt Uniform and still has a rainbow vapor trail despite the rest leaving the iconic actual thundercloud vapor trail.
