Bio: For all of her life, Darkflare teased and pranked Cloudburst. When Cloudburst was 5, Darkflare was speeding around the house, being annoying. She eventually passed by the fireplace, setting her tail on fire. Cloudburst tried to help, but she singed her mane. Darkflare finally went outside and flew through a rain cloud, putting the fire out.
At around 15, Cloudburst still didn't have her cutie mark. She knew she wanted something helpful, but she was terrible as a nurse or doctor, couldn't mix herbs correctly if her life depended on it, and was too afraid of fires to become a firefighter. She was very self concious about it, being the only pony in school without a cutie mark. Her sister's birthday was coming up, and she got to become a Wonderbolt for her present. That wasn't fair! Darkflare got to live her dreams, go and travel with the Wonderbolts--but of course, Cloudburst also saw the joy of not living with her sister for the rest of her life. She wouldn't be the victim of hundreds of pranks... Cloudburst thought about all of this, drifting into a deep sleep, lying on her cloud. But what felt like a millisecond later, Cloudburst snapped awake, being soaked with rain. But, the weather was supposed to be sunny for a few days, no where did it call for rain... "Hey, Blank-Burst! You're looking a little wet!" teased Darkflare, and Cloudburst knew exactly what was happening. Darkflare had dragged over a raincloud and decided to have a little fun with her sister. "Blank-Burst, need a towel? Too bad, you don't get one!" Darkflare shouted, flying away. Cloudburst hated that nickname, it was insulting and horribly stupid sounding. Darkflare had placed a giant, 10-foot cloud above her head, and now Cloudburst had to clean it up. She circled around it, kicking and bucking the cloud into pieces, thoroughly enjoying the process. As soon as the cloud was gone, she turned around and saw something on her flank -- her cutie mark!
After discovering her talent and passion for weather control, she realized that it was a very important and helpful job. It might not seem like it at first (Oh, great, snow. Like that's gonna help anypony) but without it, no rain would fall, lakes would run dry, plants would wither, and everyone would starve to death. (And everyone died happily ever after, the end.)
Now, Cloudburst works at the weather factory, moving clouds into place, destroying rogue clouds, and helping out with any tasks if necessary.
