MLP: Dynamite Dash

Rainbow Dash's older sister. I figured out her name and story before finally settling on her appearance. She lived with Rainbow in Cloudsdale when the younger Dash was just a little filly, but left with two other friends, Lovely and Wonder. She was the fastest pegasus in Cloudsdale, but, while proud, is less likely to show off her talents than her sister. When she bursts into her fastest speed (nearly matching the sonic rainboom) she leaves a trail of flames in her wake.
