Dexter's Laboratory Wiki

Dexter's Laboratory is an American animated television series created by Genndy Tartakovsky for Cartoon Network. Initially debuting on February 26, 1995, as a seven-minute World Premiere Toons pilot, it was expanded into a full series after gaining network approval. The first season, which consists of 13 episodes divided into three segments each, premiered on TNT on April 27, 1996, and TBS and Cartoon Network on April 28. A second season of 39 episodes followed in 1997. In this season, Allison Moore, the voice actor for Dee Dee, was replaced by Kathryn Cressida, save for a few episodes. "Last But Not Beast", the second-season finale, was originally supposed to conclude the series in 1998. However, Tartakovsky directed a television movie titled "Dexter's Laboratory: Ego Trip" which aired on Cartoon Network on December 10, 1999. He left the series after the movie, focusing on his other projects, Samurai Jack and Star Wars: Clone Wars.

Production on a third season began in 2001 with Chris Savino taking over as creative director and later producer. It premiered in worldwide on November 18, 2001, during Cartoon Network's "Dexter Goes Global" marathon. The third-season episode "Poppa Wheely/A Mom Cartoon/The Mock Side of the Moon" is the first to feature Christine Cavanaugh's replacement Candi Milo as the voice of Dexter. Milo would voice the character from the next episode onward, with the exceptions of "Tele Trauma". A fourth and final season consisting of 13 episodes aired from November 22, 2002, to November 20, 2003. In total there have been 78 episodes and a television movie across 4 seasons. Also released was a controversial unaired episode called "Rude Removal", which was originally only shown at certain comic conventions. The segment was later picked up by Adult Swim and released to the public on January 22, 2013, online.

Believing them to mean him, Dexter travels to the future in order to see this event happen. He is horrified to find himself a wimpy young man, who works designing office cubicles for Mandark, his boss. Dexter convinces his older self that he is a genius who will one day save the future, and they travel to a later time together. Although they arrive in a scientific utopia, they find that the Dexter in this period is a doddering old man who can barely remember anything he has ever done. Backing up a few years, the three Dexters discover the world has fallen into ruin, and the inhabitants are extremely stupid. The Dexter in this time is a muscular hero, who reveals that Mandark stole his most prized invention, the Neurotomic Protocore (which D22 left in his cubicle). However, Mandark did not use the core correctly and reversed its energies, causing the widespread stupidity and allowing him to forbid technology to all but himself. All four of them team up to bring down Mandark, using the laboratory to build a large robot to storm Mandark's castle. When they arrive to confront Mandark, he summons his counterparts from the time period of each Dexter. At the climax of the battle, Dee Dee appears from the time machine and is revealed to be the one who saves the future (due to her curiosity about buttons). In a jealous rage, the Dexters build and send back through time an army of robots to destroy her — the very same seen at the beginning of the film. As the original Dexter returns to his own time and sees himself fighting with the robots, he realizes he has completed the cycle of events. However, tired of the whole ordeal, he decides to forget it and have a snack.
