EquipmentĪs a Legionnaire, Jenni carries a flight ring and utility belt. She is fast enough to run on water and was also able to break through the timestream without the Cosmic Treadmill thanks to some coaching from her grandfather, Barry. While XS' top speed has yet to be clocked, it is readily apparent that she can move at super-sonic speeds (at least MACH 10). She can vibrate at super-human speeds, allowing her to eventually phase through matter. Jenni can run at superhuman speeds and projects an aura that makes her immune to the extreme heat she puts off while running. She reappeared in Final Crisis: Legion of 3 Worlds, where it reveals that Jenni and her family were from New Earth. XS appeared in Infinite Crisis, where she and her teammates are back on Earth-247, trying save world from the Crisis. In Dead Heat, Jenni meets her cousin Bart Allen and other speedsters in 20th century to take on Savitar.

Gates elected to accompany her, while the rest of her team of Legionnaires returned to the Multiverse. After suffering the loss of her father when Earth-247 collapsed, Jenni opted to stay on New Earth following the mission to try and seek out estranged family members. Soon after they arrived on Earth-247, her mother and uncle were killed under unknown circumstances. She finds out that her family escaped to Earth-247 because Professor Zoom was after them. During this encounter, Jenni learned that she was originally born on New Earth. Her team of Legionnaires was plucked to New Earth to team with two other Legions in stopping Superboy-Prime.

Eventually, Earth-247 was destroyed and being stuck in the timestream was the only thing that saved Jenni's existence. XS served with the team until an encounter with the Teen Titans and her cousin Bart and the Fatal 500 left the Legion trapped in the timestream. They were eventually rescued by a reformed Legion of Super-Heroes who recruited them back into the fold. She and Star Boy stayed behind on Xanthu while the planet evacuated and single-handedly staved off Robotican forces for sometime. XS joined Star Boy and Dreamer on the planet Xanthu, where they succeeded in rescuing countless people from the Robotica invasion. The two began to flirt but were soon separated by the Legion's dissolution following the Blight invasion. Following the team's reuniting, she accepted her crush on Cosmic Boy would go nowhere and discovered she had accidentally been shooting down advances from ex-Legionnaire Magno. When a team of Legionnaires were once stranded in the 20th century, XS was ironically left at home in the 30th. XS had a lot of familiarity with time travel, having traveled to the 20th Century several times, where she met her cousin, Bart Allen. She developed a crush on leader Cosmic Boy and later M'Onel both went unrequited. She became a valued member of the team, her super speed saving the whole team early on when she single-handedly rescued them from the funeral bombing of Kid Quantum. She worked with the United Planets scientists to gain some control of her powers and was thus drafted into the Legion of Super -Heroes as the representative from Aarok. Character Evolution Reboot / Earth-247 XS (Earth-247) XS was created by Tom McCraw and Jeff Moy. She used it to rescue her father and escape from the Dominators. This had the desired effect and her super-speed kicked in. Knowing that stress was likely to bring latent superpowers to the four, they forced Jenni to watch as they tortured her father. She was captured by the Dominators, an alien race with a long-standing interest in metahumans who knew of Jenni's heritage.

This left Jenni alone with her father, having not developed any abilities of her own. 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. Jenni and her cousin Bart Allen were raised to adolescence, a short span of time for Bart who aged rapidly. 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.
