Dexter's Laboratory: Ego Trip is an Annie Award-winning one-hour animated television special spawned from the Cartoon Network animated television series Dexter's Laboratory, produced by Hanna-Barbera (now Cartoon Network Studios) for Cartoon Network, and aired in 1999. The film features the protagonist Dexter going to the future to see his futuristic versions of himself and his eternal rival Mandark to stop the latter from taking over the world.
Ego Trip was originally intended to serve as the series finale for Dexter's Laboratory, but due to a mixed reception from critics and high viewer ratings, the series was picked up for two more seasons with the first episode, Streaky Clean, airing on November 16, 2001.
Robots from the future come to destroy Dexter because he saved the future. Dexter defeats them and because of hearing that he saved the future, he travels into the future to find out what it is that he did.
After routinely chasing the evil Mandark (Eddie Deezen) out of his lab when he tries to steal the "Neurotomic Protocore", Dexter (Christine Cavanaugh) is confronted with a group of robots that have appeared from his time machine. They declare that they are here to destroy the one who saved the future, and make ready to attack Dexter. Dexter easily destroys them with the use of various tools and gadgets from his lab. However, news that he is "The One Who Saved the Future" intrigues him, and he decides to travel through time to discover how cool he is.
In the first time period he visits, Dexter finds a tall, skinny, weak version of himself working in office-designing cubicles, with Executive Mandark as his rich, successful boss. The child Dexter unwittingly reveals the existence of blueprints regarding the Neurotomic Protocore from the beginning of the movie, and Executive Mandark steals it after the two Dexters move forward in time.
In the second time period, the two Dexters meet their much older self, a wizened senior citizen Dexter about the same height as the child Dexter (and Mandark as a "brain-in-a-vat", renamed as "Braindark", who can never do anything other than only complain about his situation). All the technology from the blueprints has been implemented, creating a utopian society where anything can be materialized with the power of the mind. Old Man Dexter can't remember how he saved the world, so they travel back in time to find out.
In the third time period, which appears to take place between the first and second time periods, they find a dystopic world where everyone is stupid and knowledge, science, society and technology are forbidden, controlled by Overlord Mandark, thanks to his plan about the Neurotomic Protocore. They meet Action (Hero) Dexter (Jeff Bennett), who is tall, muscular and bald (senior citizen Dexter, it turns out, wears a wig), as well as having grown a large beard and huge muscles while digging underground after Mandark stole the plans. They go back to Dexter's laboratory and build a giant robot to invade Overlord Mandark's fortress. Reaching there, they are faced by the monstrously corpulent dystopian Overlord Mandark, who has summoned versions of himself from other time periods to oppose the Dexters. A battle royale ensues, with each Dexter fighting the Mandark of his own time period.
While the Dexters struggle to prevent the Mandarks from using the core, the Dee Dee from the present timeline unknowingly is transported to hero Dexter's time and undos Overlord Mandark's dystopia by pushing a button, setting the core's flow from negative to positive. The other Mandarks are transported back to their own timelines and the dystopian Overlord Mandark is reduced to nothing but his brain, meaning that he is now Braindark, which explains about brain-in-a-vat situation from Dexter and D22's earlier encountering. After DeeDee leaves, the Dexters are upset to know that DeeDee was the one to save the future, not Dexter. In response, the Dexters build robots from the remains of Mandark's lair and orders them to destroy the one who saved the future. With the core now at a positive flow, the Dexters bid each other farewell and return to their own times.
In the present timeline, he is shocked to find that the robots he sent were destroyed by himself, the Dexter who went to the future earlier. This confuses Dexter, and he goes to eat lunch. He then glares at DeeDee when she comes up to greet him and walks away, confusing her.
- Dee Dee (Cameo)
- The Time Machine is the same--if not similar--to the one used in DeeDeemensional.
- The first time traveling into the future, Dexter realized his original house interior was changed,and his family moved out. This could explain--through cartoon logic-- the re-designing of Dexter's house in the new seasons.
- For her performance as Dexter in Ego Trip, Christine Cavanaugh won an Annie Award for Outstanding Individual Achievement for Voice Acting by a Female Performer in an Animated Television Production.
- This movie was supposed to be the final episode of Dexter's Laboratory, as Genndy Tartakovsky left after producing the film (although he made two more episodes; one which aired during the theatrical release of the Powerpuff Girls Movie, "Chicken Scratch", and another one for the final produced episode "2Geniuses 2Gether 4Ever"). Due to the show's huge popularity, however, Cartoon Network wanted to give Dexter's Laboratory two more seasons. Genndy Tartakovsky has worked with Chris Savino on the first two seasons of Dexter's Laboratory, so Tartakovsky decided to hand his direction over to Chris Savino (storyboarder for season 1 and 2) during the revival the series, which premiered in 2001, and was met with mixed reviews.
- Dexter's Laboratory wasn't the last Cartoon Network show Chris Savino would run during its last two seasons, he also ran seasons 5 and 6 of the Powerpuff Girls.
- Chris Savino is also recognizable for creating The Loud House for Nickelodeon, until he was fired for sexual harassment in 2017.
- Much of the show's new crew included Chris Reccardi (co-creator of the Modifyers) and Aaron Springer (creator of Korgoth of Barbaria). Some of the show's old crew did stay for the revival run, such as Cindy and Clayton Morrow (who both also worked on the Powerpuff Girls and Chowder) and John McIntyre.
- This is the only episode that has cel animation with the season 3-4 design of Dad and the seasons 3-4 art style of Mandark's Laboratory. "Rude Removal" was the only episode after this to use cel animation, but neither Dad nor Mandark's Laboratory were seen in this episode, so it's hard to tell if they still had the newer designs. Most likely, they didn't, since the episode was produced in 1998.
- The character redesigns for seasons 3 and 4 were actually done by Chris Battle, who also designed characters for the Powerpuff Girls and AAAHH!!! Real Monsters.
- This is the final Dexter's Laboratory-related project to be produced by Hanna-Barbera before its closure in March of 2001 following the death of co-founder William Hanna, and the last to use traditional cel animation.
- Additionally, this special uses a CGI variant of the 1970s Hanna-Barbera swirling star logo (as seen after the end credits of fellow Cartoon Network series, The Powerpuff Girls) rather than the oval logo with Dexter's face, as seen throughout Season 2, or even the two rare 1996 prototype variants of the Cartoon Network Studios logos as seen throughout Season 1.
- This is the only episode rated TV-Y7-FV.
- For unknown reasons, Mandark dons on a more sinister persona and attire in contrast to his more nerdy look from the series and his lab is completely remodeled for unknown reasons as well. The reason for Mandark's sudden eviler turn and his lab's complete redesign is never explained, although it is likely that he became corrupted with power due to the potential of the protocore or that he simply became corrupted due to his past with Dark Forces.
- The movie has so far only existed in VHS and (an ultra rare) Video-CD formats. No release dates for future DVD or Blu-Ray has been announced.
- This is the last part of the series to be directed by Craig McCracken and Genndy Tartokovsky and the last part of the series in the 20th century.
- When Dexter kicked Mandark out of his house, the driveway is missing.
- Dexter was underdressed piloting his Dexo-Transformer, after summoning the Robo-Dexo 2000 to crush the last robot-- he's seen in his lab coat exiting it.
- When Dexter is escaping the Police in the first future, the front door closet is briefly shown to be open already. In the next scene, it is closed again.
- When a nude Number 12 was automatically dressed clothing by the machine, he was given a pair of black pants and a white coat, but with no signs of underwear visible underneath his pants. But when Number 12 is stripped off his clothes to be publicly spanked by Executive Mandark, he is seen in his underwear.
- When Dexter tells his wimpy self to stop typing, Wimpy Dexter's pants turn white.
