Summary: Julie has been described as a "home-grown Atlas*." Her powers are akin to those of the mighty alien superhero, but she hails from Earth rather than the stars. She has yet to chose a "hero name" for herself, and she says she's not entirely certain she'll keep her current costume design.

 

Julie is one of what have become known as "common heroes" or FISSs (an acronym for flight, invulnerability, strength and speed).  Her powers, while indeed super, are hardly unique. Other metahumans of her ilk have sometimes found life easier if that stick to the "normal" career paths and keep their powers in the closet. Only time will tell if Julie will decide what to do with her talents.

Like other meta-humans with her power set, Julie is vulnerable to the fabricated element Argonite which weakens her and dampens her powers.
