Dexter's Laboratory: Ego Trip

Dexter's Laboratory: Ego Trip is a 1999 animated science fiction comedy television film based on the animated television series Dexter's Laboratory. It was produced by Hanna-Barbera Cartoons and originally aired on December 10, 1999, on Cartoon Network. The film follows Dexter, the series' titular protagonist, as he travels forward through time and meets futuristic versions of himself and his rival Mandark.

While made for television, the film is the directorial debut of series creator Genndy Tartakovsky and was originally intended to conclude the series before it was revived in 2001. Ego Trip was the first Cartoon Network television movie produced, and is the final Dexter's Laboratory installment to be animated using traditional cel animation. It also marked one of the final performances of Christine Cavanaugh as Dexter before her retirement from voice acting; Candi Milo would replace her during the third season of the series.
