Julie received her powers shortly before the events of the series from an unnamed alien (most likely this reality's version of Aelfyre Whitemane) when the time came for him to pass them on. Shortly afterwards, the family moved to a new neighborhood. Julie mostly used her powers to perform chores like cleaning up her room, or hang out with her new friends from school. She did not participate in her siblings adventure to return the medaillion of Dr. Mobius to the haunted house it came from.
Powers and Abilities
As Lightspeed, Julie can move around at supersonic speeds while emitting a distinct rainbow colored trail. Her top speed is unknown. However, unlike most other incarnations of the character, this version of Julie Power apparently cannot fly.
Julie can ride a bicycle.
