Julie Finster, distant relative of Suzi Fusion, comes from a family that hasn't had many direct relatives who wear costumes and fly about. To make matters worse, Julie is the 84th person with the FISS powerset (Flight, Invulnerability, Speed, Strength), making her somewhat common and unfashionable in the super-heroing world. Her cousins, the atomic-powered 'Nuclear Family' have come to town, lording their fame and fortune over Julie's household. Can her self-confidence survive? And what's with all the demons and cherubs flitting around Wonderburg?
