Robert Grayson is the 1950s Marvel Boy, debuting in Marvel Boy #1 (Dec. 1950), from Marvel 1950s forerunner, Atlas Comics. He continued to appear when the series title was changed to Astonishing with issue #3. Created by writer-editor Stan Lee and artist Russ Heath, with writer-artist Bill Everett taking over with issue #2, this Marvel Boy is the son of Dr. Horace Grabshield (later Anglicized as Grayson), a scientist who fled Earth to Uranus with his infant during the rise of Nazi Germany. His final story during this period was in Astonishing #7 (Dec. 1951). He returned in Fantastic Four #165 (Dec. 1975) under the name "The Crusader", and appeared in the 12-issue ensemble miniseries Marvel: The Lost Generation (March 2000 - Feb. 2001) and elsewhere, eventually joining the superhero group Agents of Atlas.
