Moore recalled that he was unsure if DC would allow the creators to depict the character as fully nude, which partially influenced how they portrayed the character. Gibbons wanted to tastefully depict Manhattan's nudity, selecting carefully when full frontal shots would occur and giving him "understated" genitals—like a classical sculpture—so the reader would not initially notice it. Dr. Manhattan's forehead is marked with the atomic structure (specifically the Bohr model) of hydrogen, which he put on himself, declining a helmet with the atom symbol.
