Dexter's Laboratory: Ego Trip

Dexter's Laboratory: Ego Trip (1999) is a feature-length animated special you can watch online on iFILM. It's the first big-screen outing for Cartoon Network's pint-sized boy genius and his secret lab.

Robots crash into the lab with orders to destroy "the one who saved the future." Dexter scraps them in seconds with the gadgets lying around, but the title sticks in his head, so he fires up the time machine to go meet his grown-up self. The truth stings. In one future he's a scrawny office drone designing cubicles, while his old rival Mandark lounges around as a rich, smug boss.

Created by Genndy Tartakovsky, who would go on to make Samurai Jack, the special runs on his trademark sharp angles and faster, snarkier gags. Fifty minutes, no filler — pure nostalgia for anyone who grew up glued to the channel. The original title is Dexter's Laboratory: Ego Trip. Stream it online on iFILM.
