Jacqui, originally a male pegasus, is now a 30-year-old female changeling, renowned for her performances as a metal musician, and respected for her unique skills as a sound engineer. Born in Manehattan, her early life involved moving between cities, including Appleloosa and Ponyville, where she developed a countryside accent and faced a series of unlucky relationships. At 26, she transformed into a changeling at the request of her ex-boyfriend, though the process left her with a unique mix of pegasus and changeling traits. After reuniting with her childhood friend, Emerald Ink, their friendship blossomed into love, leading to marriage and the birth of six children. Jacqui later underwent a metamorphosis, gaining magical abilities, changing her gender to be female on a more permanent basis, and successfully reunited with her two lost children, completing her family. Despite personal challenges, Jacqui continues to thrive in her music career, touring across Equestria and beyond.
