Months later, Mister Fantastic went into space to expose himself to cosmic radiation to revitalize his own powers. Unknown to Richards, Kragoff, still intangible, was also aboard the spaceship. Kragoff used his invisibility to hide from Richards for days until he was able to immerse himself in cosmic radiation, restoring his powers to what they originally had been. The Red Ghost could again become tangible or intangible and visible and invisible at will. He even gained the power to make other objects in his vicinity intangible and invisible. Fully recovered, he battled Mister Fantastic, and escaped.
