Jenni is the second (by six minutes) child of Bart Allen and Cissie King-Jones.
HistoryJenni was born six minutes before her twin brother Max on June 12, 2017.
Jenni is fairly introspective, compared to her twin. She likes to think before she acts, and often creates multiple plans before deciding on a course of action. She is the plotter, Max is the do-er. She started playing the piano when she was eight; she likes it because focusing on the tempo forces her to slow her thinking down.
Jenni's powers manifested at a young age, giving her the ability to run at high speeds when she was as young as three. She has the ability to perfectly recall everything she reads. She is also abile to think at high speeds, and is therefore excellent at predicting events and is a very good strategist.
Jenni is especially close with her twin brother, Max. She adores her big sister Ick and is very protective of her little brother Bat.
Jenni is very much her mother's daughter, but she looks to her father as her role model for the type of hero she hopes to become.
Jenni uses the codename Impulse in honor of her father.

Jenni's PB is Tessa Allen.
