Show Summary

Dexter's Laboratory is the story of a young boy prodigy. Born with an extraordinary mind, Dexter has built his very own extremely high-tech and expansive laboratory in his room that NASA could only dream of. But Dexter has to keep his lab a secret for fear others will exploit it. Through out the years, Dexter has had to hide his lab from his parents and others but it is no easy task. All Dexter wants is to spend all the time he can inventing new things in his lab, but between his stupid and annoying older sister Dee Dee constantly barging into his lab and tearing up the place and his arch enemy and rival genius Mandark constantly tiring to take over his lab, Dexter's life is anything but easy. Dexter's Laboratory was originally premiered on Cartoon Network as part of the inaugural, Space Ghost hosted, "World Premiere Toons" before becoming a feature with two full shorts on the regular series, a.k.a. the What a Cartoon Show, it eventually became a series itself. Characters: Dexter - Dexter is the big guy here to spite his short size. Dexter's IQ is enough to rival his role model, Albert Einstein. Dexter is an impressionable little boy who loves action. He is always looking for a fight in his giant Robo-Dexter or against his rival, Mandark and when he isn't doing that or working in his lab, he is playing with his action figures or watching TV. You would be hard pressed to see Dexter outside unless he is doing some sort of experiment or fighting some sort of evil. But other than all that, Dexter spends all his time in his lab. Dexter is constantly working on something new and building on to the lab. So much in fact that he has some inventions he can't even remember making and there are parts of the lab he doesn't know anything about. Naturally, Dexter is the head of his class much to the dismay of his fellow students. Dexter is pretty much devoid of friends but he isn't really bothered by it. As long as he can work in his lab, Dexter lives on. Dee Dee - Dexter's older sister is a very happy and delightful girl. Being taller and older than Dexter gives her a sisterly edge. Dee Dee is one of the few who knows about Dexter's lab as she stumbled upon in when the both were younger. But Dexter does not need to worry about her spilling the secret as no one would believe her even if she did. Dee Dee lives in her own little world complete with unicorns, imaginary dragons, and talking ponies. Her room is a pink nightmare of stuffed animals and dolls that Dexter must avoid at all costs. So naturally, no one really takes her seriously. She is a dancer and a singer but insists on practicing in the lab and wreaking the place in the process. She also has some athletic skill in most sports. But behind it all, Dee Dee is actually a very caring sister who does truly love her little brother. Mom - Mom is a happy home maker who can't stand filth in any form. You will be hard pressed not to find her wearing her yellow gloves. She, like Dexter, wears them everywhere. Mom always has dinner on the table by the time Dad gets home and is always willing for a bit of "playing around" with her husband at anytime. She gets the kids on the bus in the morning and off in the evening. Just your standard work at home Mom who sits on the brink of insanity at times. Dexter seems to take after her with her hard work ethic and inability to stop once she starts. She works in the kitchen much like Dexter works in the lab and hates it when Dad drops in to bother her. Dad - Dad is the typical working man. He leaves in the morning for work and comes home in the evening for dinner. He loves sports and working with his tools. He is a handy man and handles most of the hard work around the house. He likes to mess around with his family, especially Dexter. He enjoys annoying his wife in the kitchen and giving her a playful little pinch in the butt. His constant attempts to get Dexter out of his room and into a uniform of some sort usually are forfeit. He is an outdoors man as well. He loves to fish and camp. Dad is a very laid-back guy. Dee Dee seems to take after Dad with his sports skill, his love of the outside, and his thrive at being annoying. Mandark - Mandark is Dexter's rival and he is totally evil. Mandark is on the same intellectual level as Dexter and has proved it many times. He also has his own lab in his room though it doesn't seem to be a secret as Dexter's. Mandark's lab is bigger and better than Dexter's and he never misses a chance to reminded Dexter of that fact. Mandark's #1 ambition is to shut down Dexter's lab thus making him the only genius around. Mandark is always looking for a way to outdo Dexter in anyway possible. Mandark also has a major crush on Dee Dee which is a point that Dexter exploits all the time. His parents are actually peace loving and hippies in a sense. He repents his parent's ways, but still is forced by them to do peaceful rituals when the time comes.

    • Don't hate me for this...

      I hate this show so much!
    • For the most part, this was a good show.

      I mean, the show had likeable characters, funny humor and creative a unique concept. Dexter has a secret laboratory in his room that his older sister, Dee Dee, always barges in to screw things up while their parents are none the wiser. My problem? The writing, again. Some of the episodes had some really bad writing even before it went through seasonal rot. For example, there was this episode were Dexter makes a dog talk and nobody is phased by that fact. Another episode had Dexter trying to get some ice cream and the ice cream man won't give him any because-SPOILER ALERT- the last time Dexter paid for ice cream, he paid in pennies and ruined the guy's life. I'm not kidding, that's why he was the antagonist of the episode; and let's not forget the Christmas special, the episode where Mandark impersonates Dexter's Mom, and the infamous banned episodes, Barbequor and Rude Removal. And let's not forget the seasonal rot era, where the show overstayed its welcome and should've ended when CN had the chance. Guess that's what happens when people keep asking for more episodes instead of being satisfied with the ones they got. Yes, I would love shows like Invader Zim to be brought back, but I'm content with the 26 episodes that we got; I mean, it's better than nothing right? All and all, Dexter's Lab was a good show; not the best, but still fun to watch none the less.moreless
    • A great show that unfortunately went downhill later on.

      Dexter's Laboratory was a really great Cartoon Cartoon. The story behind it was pretty good. A boy genius, Dexter, invents things in his laboratory, while trying to prevent his (In his mind) "stuuupid" sister Dee Dee from destroying it. He also tries to outbest his rival, Mandark in everything thats science. There were also some pretty cool side stories involving superheroes. Like The Justice Friends (An obvious parody of the Avengers) and Dexter's pet monkey, well, Monkey.

      Admittedly though, I thought that Dexter himself could be pretty arrogant. Not as in he's got a bit of an ego on him, but still has likable traits. No I mean that he's a genius who talks down on people for not being as smart as him, especially Dee Dee. Jeez, I couldn't help but think what a jerk he was! Though to be fair, Dee Dee could be pretty annoying too. I do really like Mandark though. He's the perfect evil counterpart of Dexter, his laugh is so stupid that it's actually kinda funny to listen to, and he can be rather arrogant too. But his arrogance is acceptable because he's the rival of the show.

      Dexter's Lab also had a lot of funny parts in it, and there was plenty of action in more than a few episodes. It also ended on a good note with the movie Ego Trip. Or so I thought. When the 2000s came around Cartoon Network decided to bring the show back. Turns out, it wasn't such a good idea.

      Who were the people who decided to make those last two seasons? A whole new creative company apparently. They changed the animation and they got a new team of writers, who completely messed up the show. They changed so many things that made the first two seasons good. The biggest thing they screwed up on was they changed how Dexter and Mandark met. The only episode that was really good was the "Wacky Races" parody episode. Apart from that, Dexter's Lab got pretty stupid.

      But even though the new series wasn't that good. The old series was a really good show. In fact, the first two seasons is what I'm really scoring the show on, cause I don't even consider the newer series canon. Dexter's Laboratory was one of Cartoon Network's best shows, and it deserves to be remembered for the first two seasons.moreless
    • Great Show

      Dexter rocks so bad xD! Too bad they canceled it. Hope it is on for re runs.
    • Love the show

      One of the best tv shows that ever hit my childhood. I have to be honest, the old Dexter was WAY more better than the new one.
