A sort of movie that explores Dexter's actions and achievements through history.
A few robots come from the future, apparently to do him in, he defeats them and travels there to see how he saved the future, as the robots prophesied. And so the adventure begins.
Some say this is one of the darkest movies of the series, and it includes torture and lots of action considering it's a cartoon and especially pertaining to the Dexter series. However, some funny moments catch your eye from time to time too.
Ah, finally changed the image, I'm glad to see people still seed this.
