Origin of Superman early issues of the series, it was unclear if the story was intended to be the new origin of the mainstream Superman or the beginnings of a new universe, similar to Marvel's Ultimate line. DC later confirmed that "Birthright" was the new official origin of Superman, and it was embedded into the Superman fiction in "Superman" (vol. 2) #200. Krypton was redesigned again in "Birthright", portrayed as a society that used its advanced science and technology to make its planet into a paradise. Clark Kent respected his alien heritage and designed his Superman costume based on images of Kryptonian culture
Publication history of Superman Superman encountered a fictional cartoonist provided a tongue-in-cheek look at how such work was delegated. The story, which purported on the title page to tell "how comic strips are written and drawn", showed a studio filled with "artists -- stacks of them -- figure men, background specialists, inkers, letterers" as well as script-writers, all devoted to the production of stories about a Superman-like character, while the original creator of the strip was to Superman's consternation kept busy answering his fan mail ("King of the Comic Books", Superman no. 25, 1943). In the early stories, Superman is the only science-fiction element.
