My first proper pony OC. She was originally going to be a unicorn, but earth ponies need love too, yo.  
Here’s a few cliff notes about Lightning Stripe.
 
• Lightning Stripe is a mute and cannot speak, instead communicating through her actions.  
• She is able to store electricity from lightning bolts in her body and discharge it at any given time. While charged she can run especially fast, although the charge will run out after a while. When this happens Lightning will need to recharge if she is to keep up the same pace.  
• While Lightning Stripe is charged, her cutie mark glows.  
• She has a tendency to be ditzy and easily distracted.  
• The stripes on her face are her interpretation of make-up. (She doesn’t quite understand how make-up works.)  
• Lightning wears socks to prevent her charge from going straight into the ground. Should she touch the ground with a bare hoof (or any exposed part for that matter) she will lose any stored electricity.
