Maxwell is the main character of Scribblenauts. Players take control of Maxwell, and use him to interact with the different levels and grab the Starites. Maxwell may be able to run and jump, but without your help, he can do little else. It's up to you, the gamer, to bring to life any noun you can come up with to help Maxwell reach the Starite.

Much has been made of Maxwell's unusual appearance, including what Destructoid has dubbed his "Rooster Helmet". In an interview with Joystiq, Jerimiah Slaczka admited that Maxwell went through 20 designs before settling on this one, and has decided to officially endorse the name of Maxwell's hat as a "Rooster Helmet".

You'll notice that the notebook that he scribbles his objects from has the logo of 5th Cell on the back.
