9th Wonders! is a metafictional comic-book series in the NBC drama Heroes. In the show, it is written, illustrated, and self-published by Isaac Mendez. In reality, Mendez's artwork is provided by comic-book illustrator Tim Sale.
9th Wonders! is self-published, as the creator's name and home-studio address appear prominently in the back of the issue. The "official" company name listed on the issue's cover is the "Helix Comics Group" (a reference to the TV series' helix symbol). The "official/unofficial site" is 9thwonders.com
9th Wonders! is presented as a new series; an issue being read by Micah Sanders is visible in the debut episode "Genesis". Also in this episode, Hiro can be seen with 9th Wonders! artwork on his computer monitor. During the second episode, "Don't Look Back", another issue is visible with its cover numbering partially obscured. It is shown in the following episode to be number 14. The nature of the book appears fluid, as Nakamura references it heavily in order to receive prompting for his choices of action, leaving even the final page count (monthly books averaging 21–24 pages) in question. However, this is not fully explained.
In ".07%", Isaac Mendez is in his gallery with a courier who is an avid fan of the comic. He shows the courier the new issue and tells him that in it, Hiro travels to the future. He also says that it is the last issue, as he had just found out that he was going to die through his portraits. Isaac then gives the courier his sketchbook and sends him on his way. In "Five Years Gone", Mohinder shows the past Hiro Nakamura the comic book and tells him that the events in the book show that Hiro kills Sylar in the past, but this had not happened in the future that they were in. Later, Mohinder injects The Haitian with the poison intended for Hiro (as shown in the same comic). Mohinder gives Hiro the comic and sends him to the past again with Ando. This comic is then taken by Ando in order to help him find Sylar but upon confronting him in "How to Stop an Exploding Man", Sylar overpowers Ando and takes it for himself. Amused by the idea that Hiro would be able to kill him, Sylar disregards the comic.
In the second season, Bob is shown reading an issue of 9th Wonders! while waiting for Mohinder to arrive in the episode "Kindred". In "Fight or Flight", Micah shows Monica issue #10 of 9th Wonders!, which includes a character called St. Joan whom Micah describes as a muscle mimic or copycat (similar to Monica's ability). The blade held by St. Joan on the cover can be seen in one of the cases in the vault where Peter vaporizes the Shanti virus in "Powerless". Also, in "Four Months Ago", Micah is shown with a 9th Wonders! birthday cake.
In the third season episode "One of Us, One of Them", a turtle is briefly seen crawling by a copy of 9th Wonders!
