Samurai Jack (2001)

In the distant past, a Japanese samurai (Phil LaMarr) embarks on a mission to defeat the evil shape-shifting wizard Aku (Mako and Greg Baldwin). Before he can complete his task, though, he is catapulted thousands of years into the future. He finds himself in a world where Aku now enjoys complete power over every living thing. Dubbing himself "Jack", he sets out on a new quest – to right the wrongs that have been done by his enemy, and to find a way back to his own time so he can destroy the evil for good. —Alan Back <ajback@yahoo.com>
