Simon Pooni, an angry, bitter 12-year-old boy suffering from multiple sclerosis, idolizes superheroes, particularly Superior, a Superman analogue. An alien monkey named Ormon appears at Simon's bedside, informing the boy that of all the people on Earth, he has been granted the honor of being bestowed a single magic wish. Simon is then transformed into Superior. After playing the role of Superior for a week, he learns that Ormon is actually a demon incarnate, and he must sell his soul to the devil in order to remain as Superior. He is given 24 hours to decide, and is returned to his old body. The demon approaches an old bully of Simon, and offers him a similar wish, to become Superior's fictional nemesis, Abraxas; the only caveat is that he must pledge himself to Satan. Simon must then choose whether to become Superior again and save the planet from imminent destruction at the cost of his own soul. To force Simon to choose, Abraxas begins destroying the city. Simon transforms into Superior and fights both Abraxas and Ormon. Although Superior defeats them in battle, Ormon gloats that he still has Simon's soul, until he realizes that Simon is immortal, and that his soul can never be collected. Ormon is dragged back to Hell as punishment for his failure, and Simon reverts to his mortal form. The world honors Superior as a fallen hero, thinking him killed in battle, and Simon returns to his former life, but now at peace with himself.
Promotion
Prior to the release of the series, a marketing campaign featuring a Wizard magazine cover and a series of prophetic teaser images – all of which evoked Millar's love for the Superman mythos were released. Creator Mark Millar also gave comic stores across the world chance to earn a free full page advert in the books first issue by printing off and displaying promotional posters from his official website in their stores. A charity auction was held to name the main character. The winner, Simon Pooni, chose his own name.
In Kick-Ass 2 there is a poster of Superior in a flashback of Dave's childhood. In April 2014 it was announced 20th Century Fox had picked up the rights to a feature film.
