Giant-Man is the alias used by several superheroes appearing in American comic books published by Marvel Comics, usually in association with the alias Ant-Man. Hank Pym first appeared as Giant-Man in Tales to Astonish #49, though he had appeared multiple times before, first in #27 as a civilian, and in #35 as Ant-Man. Regardless of iteration, Giant-Man usually has the power to enlarge to enormous sizes. Giant-Man also frequently overlaps with the alias Goliath.
