Granddaughter of Barry Allen, a.k.a. the Flash. Jenni Ognats carries on the family tradition as the 31st century speedster, XS. Jenni Ognats is the granddaughter of Barry and Iris Allen from their time in the 30th Century, and her mother is Dawn Allen, one of the Tornado Twins. Jenni and her cousin Bart Allen were raised to adolescence, a short span of time for Bart who aged rapidly. Eventually, the Tornado Twins were killed in battle and Jenni's Grandma Iris took Bart back to the 20th century for his safety as he had manifested speed powers. This left Jenni alone with her father, having not developed any abilities of her own. She was captured by the Dominators, an alien race with a long-standing interest in metahumans who knew of Jenni's heritage. Knowing that stress was likely to bring latent superpowers to the four, they forced Jenni to watch as they tortured her father. This had the desired effect and her super-speed kicked in. She used it to rescue her father and escape from the Dominators. XS was created by Tom McCraw and Jeff Moy.
