Story  
Rainbow Flash was borned with some kind of destiny - since he looks like Rainbow Dash and even was named similar to her. When he was a colt, he didn’t even know that there’s a filly so similar to him. But when Dash did her first Sonic Rainboom (that was the cause of Mane 6’s Cutie Marks appear), Flash’s Cutie Mark appeared too. It appeared as a black cloud and a rainbow flash coming out of it - this is a symbol of his destiny connected with Rainbow Dash. He didn’t know what does it mean for a long time. But when he grew up, he moved to Ponyville and then he met Dash. He fell in love with her, but she didn’t even know about him (or maybe about his feelings? or maybe just didn’t love him). But since Dash was popular in Ponyville, and she even knew princess Celestia, there appeared some problems for Flash: nopony really knew him - everypony knew Rainbow Dash and when they started to talk to Flash, it was only a mistake (they all said “Oh, I thought you’re Rainbow Dash, sorry” and walked away). Flash was so lonely and felt so bad, so he started to drink and smoke, and whatever else (he wanted to forget about the reality). His life became harder.  
After some time, Flash met a pony called Stringsbreaker, - a young artist who left his home to become popular. After some talk with him, Flash realized that this youngster is as lonely as Flash is, and helped him. After this meeting, Rainbow Flash and Stringsbreaker became very good friends.  
Rainbow Flash tries many jobs for earning money, but he’s always fired at last because of his bad habits. Because of it, Flash is poor, and can only live in a small, old house.
