سپس سیگل و شوستر به خلق کمیک استریپ، در زمینه های کمدی و ماجراجویی، روی می آورند. آنها می خواستند برای روزنامه های سندیکایی نویسندگی کنند، بنابراین ایده های خود را به سردبیران روزنامه های مختلف نشان دادند. با این حال، سردبیران روزنامه به آنها گفتند که ایده های آنها به اندازه کافی هیجان انگیز نیست. اگر آنها می خواستند یک کمیک استریپ موفق خلق کنند، باید ایده ای پر شورتر و هیجان انگیز تر از هر چیز دیگری در بازار خلق میکردند. همین دلیل باعث شد تا سیگل دوباره برای خلق یک شخصیت کمیک استریپ دوباره به سوپرمن رجوع کند.Jerry Siegel, quoted in . "Superman: The Complete History", p. 15: "When we presented different strips to the syndicate editors, they would say, 'Well, this isn't sensational enough.' So I thought, I'm going to come up with something so wild they won't be able to say that."Jerry Siegel. "Creation of a Superhero" (unpublished memoir, written c.1978; Scans available from Dropbox and Scribd).:"...one of the things which spurred me into creating a "Superman" strip was something a syndicate editor said to me after I had been submitting various proposed comic strips to him. "The trouble with your stuff is that it isn't spectacular enough," he said. "You've got to come up with something sensational! Something more terrific than the other adventure strips on the market!"" سیگل قدرت های سوپرمن را تغییر داد تا او را شگفت انگیز تر بکند. نسخه بعدی سوپرمن، مانند بیل دان، قدرت هایش را به طور ناخواسته از یک دانشمند دیوانه بدست میاورد. اما این دفعه به جای قدرت های ذهنی، قدرت فوق بشری و پوست ضد گلوله بدست میاورد.Tye (2012), "Superman", p. 17: "The version he was drafting would again begin with a wild scientist empowering a normal human against his will, but this time the powers would be even more fantastic, and rather than becoming a criminal, the super-being would fight crime "with the fury of an outraged avenger.""Jerry Siegel. "Creation of a Superhero" (unpublished memoir, written c.1978; Scans available from Dropbox and Scribd).:p. 30: "The hero of 'THE SUPERMAN' comic book strip was also given super-powers against his will by a scientist. He gained fantastic strength, bullets bounced off him, etc. He fought crime with the fury of an outraged avenger."50: "What, I thought, could be more sensational than a Superman who could fly through the air, who was impervious to flames, bullets, and a mob of enraged amok adversaries?" علاوه بر این سوپرمن جدید برخلاف بیل دان شرور نبود و یک ابرقهرمان مبارز جرم و جنایت به شمار میرفت. زیرا سیگل باور داشت که یک کمیک استریپ که شخصیت اصلی آن ابرقهرمان است احتمال موفقیت بیشتری پیدا میکند.Siegel in , p. 10: "Obviously, having him a hero would be infinitely more commercial than having him a villain. I understand that the comic strip Dr. Fu Manchu ran into all sorts of difficulties because the main character was a villain. And with the example before us of Tarzan and other action heroes of fiction who were very successful, mainly because people admired them and looked up to them, it seemed the sensible thing to do to make The Superman a hero. The first piece was a short story, and that's one thing, but creating a successful comic strip with a character you'll hope will continue for many years, it would definitely be going in the wrong direction to make him a villain." سیگل در سال های بعد به یاد آورد که در برخی از پنل های نمونه اولیه کمیک استریپ سوپرمن با یک شنل "خفاش مانند" طراحی شده بود، اما درکل او و شوستر توافق کرده بودند که هنوز لباسی طراحی نشود و هیچ لباسی هم در باقی مانده نمونه های اولیه وجود ندارد.. "Superman: The Complete History", p. 17: "... usually [Shuster] and Siegel agreed that no special costume was in evidence, and the surviving artwork bears them out."Siegel and Shuster in , p.9-10: "Shuster: [...] It wasn't really Superman: that was before he evolved into a costumed figure. He was simply wearing a T-shirt and pants; he was more like Slam Bradley than anything else — just a man of action. [...]Siegel: In later years – maybe 10 or 15 years ago – I asked Joe what he remembered of this story, and he remembered a scene of a character crouched on the edge of a building, with a cape almost a la Batman. We don't specifically recall if the character had a costume or not. [...] Joe and I – especially Joe – seem to recall that there were some scenes in there in which that character had a bat-like cape."
