History:Born in Cloudsdale like his older cousin Thunder Dash, Storm Rush was found always wanting to push himself to the limits. Every year, The Great Eastern Storm would come. Many Pegasus have tried to fly through this storm, but they never got through. Some have even gone down trying. In the summer of his 8th year, The Great Eastern Storm struck. He was determined to fly though it. Just like Thunder Dash, he was struck by lightning, but did not go down. He was able to fly through it. This is how he got his cutie mark. Currently, he and Thunder Dash are the only two pegasus to fly through The Great Eastern Storm.
Example RP Segment: (His pridefulness gets the best of him and his cousin has to scold him)
Storm Rush watched as the red pegasus zoomed across the sky. "Pfft, I can do sooo much better than that!" He said as he took to the sky and performed some awesome maneuvers. The red pegasus stopped and just looked at him in amazement. Storm Rush stopped. "And that's how it's done, he said landing about to walk away. However, his cousin, Thunder Dash stood in his way. "Ugh, what are you doing, get outta my way!" Storm Rush said. "I got things to do, places to fly to, storms to conquer!" He said impatiently. He then tried to go around, but Thunder Dash spread his large wings out in order to prevent Storm Rush from going anywhere. "What were you doing up there?! Didn't I tell not to show off and belittle other pegasus like that? Huh? But you wouldn't listen to me. You think you're all that. Cuz, you still have a long ways to go." Thunder Dash scolded Storm. Storm Rush felt the guilt in his heart. He knew what he'd done was wrong. He decided to go apologize to the red pegasus who was sitting on the ground with his head down. The red pegasus was hesitant at first, then realized Storm's sincere apology.
