While she was still quite young, Sue
became smitten with her aunt's handsome and brilliant tenant, science prodigy Reed Richards
; a university student at that point. Sue and her brother Johnny
insisted on coming on the maiden voyage of Reed Richards' experimental starship. But inadequate shielding allowed mysterious cosmic rays to penetrate the ship's hull and bombard the crew, forcing them to crash-land back on Earth. Upon landing they discovered that they had gained superpowers, and Sue became the "Invisible Girl."
