Ultimate Spider-Man is a modernized reboot of the Spider-Man story, starting from the very beginning, with a plot that is inspired by, but very different from, the original continuity. The main purpose of the series is to be accessible to new and young readers, as it is free from the decades of history of the original, but it has been embraced by many longtime fans as well.
In Ultimate Spider-Man, Peter is a high-school student who is bitten by a spider during a school field trip—but instead of a radioactive spider (which reflected the Atomic Age in which Spider-Man's origin was written), it is a lab subject that has been genetically modified by Osborn Industries. This idea of using genetic engineering instead of radioactivity was used for the Spider-Man film. The themes, characterization, and setting are updated to reflect modern life. It is set in the Ultimate Marvel universe.
