I needed to make a new ref of her, instead of her using hawk eyes, she just has different colored eyelashes.
 
Backstory:
 
When Lightning was about 3-4 years old, she was put up for adoption. 
She ended up getting abused in her childhood and a little bit of her teenage years. 
Lightning was abused because she was different. She has surprisingly golden eyelashes. Like a hawk’s eye. 
She was also abused because she got her cutie mark faster than anypony else in her “family.” 
When Lightning was 17 years old, Celestia gave her hoof magic which 
Lightning didn’t know how to control for the first few times around. One day, 
when she was using her chaotic hoof magic, she accidentally erased most of her memories, 
removing the memories with her actual family. She also made herself really fast with her 
chaotic powers. (not as chaotic as Discord’s, it’s hella similar to Sans’ powers). She can sense things 
using her magic. Lightning is 24 years old and she is trying to discover her actual family. 
(until I create her family, she will still be trying to discover them. lmao that made no sense…)
 
How she got her cutie mark:
 
It was a few weeks before Rainbow Dash did her sonic rainboom, and Lightning was just flying ordinarily, 
she realized she was one of the fastest fliers in Equestria and she wanted to keep it that way. She kept on 
exercising, and getting faster and faster a whole lot, then she ended up with getting her cutie mark 
way before Rainbow Dash got her cutie mark.
