Synopsis:
Professor Lang brings home a metal belt he discovered while on an archaeological dig. The belt fits Lana and gives her super powers. She wears a lead mask and wears a costume to become Gravity Girl.

Gravity Girl becomes a hero like Superboy, but she is only invulnerable to metal, wood and stone can harm her. Fearing this weakness will endanger her life, Superboy learns her secret identity and convinces Lana to give up the belt. Lana agrees and Superboy destroys the belt.
