About Adventure Time

The hand drawn animated series originally debuted as a short produced for Nickelodeon in 2007, but wasn’t commissioned as full-series by Cartoon Network until 2010 after going viral online. With nine complete seasons, Adventure Time draws inspiration from the fantasy role-playing game Dungeons & Dragons. The series centers around Finn the Human, a fiery 12-year-old, voiced by John DiMaggio, and his companion Jake the Dog, voiced by Jeremy Shada, who uses magical powers to change shape and size.

Finn journeys through the Land of Ooo left destroyed by nuclear war a thousand years prior to the series beginning. While battling evil and righting wrongs, Finn along with assistance of Jake the Dog, interacts with others like Princess Bubblegum, the ruler of the Candy Kingdom; the Ice King, the misunderstood ruler of the Ice Kingdom; and Marceline the Vampire Queen, a thousand-year-old demon/half-human. The critically award winning show has since inspired books, video games, clothing, and costumes!
