High Quality Content by WIKIPEDIA articles! Dr. Henry "Hank" Pym is a fictional character that appears in publications by Marvel Comics. Created by editor and plotter Stan Lee, scripter Larry Lieber and penciler Jack Kirby, the character first appeared in Tales to Astonish #27 (Jan. 1962). Pym`s character, a scientist that debuted in a standalone science-fiction anthology story, returned several issues later as the superhero Ant-Man, with the power to shrink to the size of an insect. Pym is eventually given a crime-fighting partner, Janet van Dyne (Wasp) and goes on to assume other superhero identities, including the size-changing Giant-Man and Goliath; the insect-themed Yellowjacket; and briefly the Wasp.
