StarBurst is a combination of Pinkypie, Fluttershy,and Derpy hooves/ Ditzy doo. Starburst is StarDust's younger twin and can be overly hyper at times, but shy and quite at other times, and though he's an amazing flyer his downfall is that he tends to run into objects. StarBurst offically owned his name when he became the first pony to fly into outerpace and do one complete lap around the sun then back down to earth with his brother stardust. Starburst's cutiemark is half of a star and when pressed up against his brothers cutiemak it makes a complete star.
