XS

Jenni inherits her speed from her grandfather, Barry Allen. Born on Aarok, Jenni grew up with no super-speed. After her mother and uncle died freeing hostages from the Dominators, making them aware of her family’s history, they kidnapped her and her father in an effort to tap her abilities. Disappointed that she had none, they began torturing her father—the sight of which activated Jenni’s latent powers. She rescued her father, and later checked herself into a research lab to learn to control her powers. Eventually, she was drafted into the Legion of Super-Heroes.

In addition to her speed, Jenni also wears a Legion flight ring that enables her to fly. One adventure left her stranded in the 20^th Century, where she played a small but crucial role in the defeat of Savitar. She briefly met her grandfather during the trip back to her own time.

The 31^st century was “recently” altered again. It has not yet been revealed whether XS still exists in this new future. The Justice Society’s Starman remembers her, but he remembers several different timelines.

Notes

* Note on Dates: The Legion of Super-Heroes stories essentially take place 1,000 years in the future. Unfortunately, this means that those stories suffer from the same “time shifting” that the present does: a story printed in 1996 would take place in 2996 with an 18-year-old character... but a story printed in 2002 would take place in 3002, and I doubt the Legionnaires have aged six years in that time.
