One of many brief aliases that Lana Lang employs in her ongoing quest to discover Superboy's secret identity. Lana assumes the identity of Sky-Girl when her father, Professor Lewis Lang, brings back a magic belt from Easter Island that gives her super powers. Wearing a lead mask, Lana becomes Sky-Girl, and gives Superboy competition in Smallville (Adv No. 189, Jun 1953: "The Girl of Steel").
