There once was a femme going to Iacon to fetch her sister home from a party at the bar. Shwas as the youngest out of three sisters. Their names are Arcee, Elita One, and Flareup. Her creator's name was Shadestreak. Their carrier died when Shadebreaker was just a baby. It was many years later that the great war started. Her sisters wanted her to be an Autobot, but schose the to be a Decepticon instead. The reason why is because she had fallen in love with Knockout, the medical officer.
