Lightning Rain was an OC that I just came up with. She is part of the next generation of The Wonderbolts after Rainbow Dash makes Captain and Spitfire Retires from military service. She was actually found by Rainbow Dash back when Rainbow was a Lieutenant. Just as Rainbow took the Captain seat she applied for the Wonderbolts. This was about two years after that she joined and Lightning Rain is part of the monster hunting squad of the Wonderbolts that was created by RD to help with covering the Everfree Forest to protect Ponyville. Because in recent years some of the monsters have been expanding their hunting area because of how crowded the forest is getting, or maybe something else is causing this no pony knows.
