The live action author is played by comedian Patton Oswalt. He was first mentioned (but not seen) in "Chin Up!" as the "forty year old dude who lives with his mom," as Timmy puts it. When the Crimson Chin asked if he made a lot of money, Timmy as Cleft pointed to the speech bubble and repeated "lives with his mom" (implying that he's either dependent on benefits from the United States government or simply sponges off his mother).
At the end of "The Big Superhero Wish!", Timmy and the Crimson Chin reveal to Nega-Chin the reason why he keeps losing is because the author makes it so. After the Nega-Chin escapes and Timmy and his fairies leave the comic book world, the author is shown trying to type up a quote for the Crimson Chin (his actions unintentionally prevent the Crimson Chin from saying a proper metaphor that would end the story in the comic book) when he hears a knock on the door. The guy at the door claims it's a delivery for him. When the author answers the door, he finds that it is the Nega-Chin.
The Nega-Chin then states he wants the author for a little chat about heroes. Before being taken away, the author tells his mom he's going out. He is then beaten to a pulp by the Nega-Chin who wanted to make sure he wins in the comic books. It is very likely this failed since the Nega-Chin is never shown defeating the Crimson Chin yet in any of the Chin's appearances after "The Big Superhero Wish!".
He’s one of two real humans seen in The Fairly OddParents, the other one was Scott Hamilton.
Although the author was mentioned to be 40, Patton Oswalt, the actor who portrayed him, was 33-34 at the time "The Big Superhero Wish" aired.
The Crimson Chin Author's name is Elmer Marmelman. This is a reference to Butch Hartman's real first name (Elmer) and the last name of one of the series' writers, Steve Marmel.
"As long as there is a single zit on the teenage face of justice...No, that's dumb, the Crimson Chin would never say that... Unless I tell him to!!"
"Oh, I hope it's a new issue of Nerds Who Live With Their Mothers Monthly."
