The titular kangaroo character of the 2003 film Kangaroo Jack. He was notorious for a hallucination sequence anthropomorphising him being the sole focus of the advertising campaign, misleading the audience into thinking he would have a more significant role than he actually did, while in the film being an ordinary animal and more of a plot device than a character.

He was given considerably more focus in the animated 2004 direct-to-video sequel, Kangaroo Jack: G’Day USA, which anthropomorphised him throughout.

Not to be confused with Jack (kangaroo jack) or Jackie (kangaroo jack), who are separate characters belonging to the artist Kangaroo-Jack.
