Shortly after Jenni's birth, their family was attacked by the villainous Professor Zoom. They, along with the family of her uncle Don Allen, attempted to flee to a parallel Earth using the Cosmic Treadmill. However, Zoom sabotaged the device, causing an explosion which created a rift in the multiverse. Zoom was ultimately defeated by an army of three different Legions of Super-Heroes, but Jenni and her family were subsequently stranded on Earth-247.
Despite her ancestry, Jenni did not at first display any signs of super-speed. However, the Dominators, knowing her family heritage, captured her. At the sight of seeing her father tortured, her latent super-speed powers activated. She managed to escape with her father before stray fire from the Dominators caused their base to explode.
After this, she checked herself into a laboratory to help her learn to coordinate herself at super-speed. Once she learned control, she was drafted into the Legion of Super-Heroes. She eventually learned to overcome her initial fear and nervousness, while she developed crushes on Cosmic Boy and, later, M'Onel, and eventually dated Dyrk Magz.
During the Legion's first trip to the 20th Century, XS was separated from them. She met her cousin Impulse, becoming a good friend. She revealed how she was participating in an archeological dig in the future. XS fought side by side with Impulse and other speedsters during the events of "Dead Heat". Afterwards, the 27th Century Flash (John Fox) fixed her grandfather's Cosmic Treadmill, enabling her to go home. Unfortunately, she overshot, encountering two further future incarnations of the Legion before returning. Impulse left her a goodbye note in the building she was participating in excavating.
XS was one of the Legionnaires left behind after many of her teammates were lost, causing the team to be forcefully disbanded. She traveled to Xanthu with her teammate Star Boy, where she found herself caught in a war between Xanthu and Robotica. While the two Legionnaires managed to save millions of lives by distracting Robotica long enough for the surviving Xanthians to escape off-planet, the two remained trapped there for months thereafter, until rescued by their returned teammates.
