Dexter secretly is a scientist for the Patriots.How else does Dexter get the money for his inventions? He gets funding from them, and is able to get help from them. Dee Dee wrecks his inventions on purpose because the Patriots hired her to make sure Dexter doesn't turn against them by him being distracted by fixing his inventions she wrecks. The reason why Dexter doesn't tell his parents? So the Patriots don't kidnap him and use them for ransom. New England Patriots? Makes sense
Dee Dee is a Yaoi Fangirl and is/was reaching puberty.Remember "Jeepers Creepers Where Is Peepers"? The episode in which Dexter and Dee Dee imaginary friend Koosie must save Peepers from some Generic Doomsday Villain? http://villains.wikia.com/wiki/Hookocho That Villain is Bishonen, Dude Looks Like a Lady, and a Walking Shirtless Scene, and basically, he's in Dee Dee's mind. Dont forget what's on his penis. And the fact that, if he destroy Dee Dee's mind/imagination, Dee Dee will no longer be a child. Does This Remind You of Anything??
- She is 12-years-old, I think, so she might be at the puberty age which supports this theory.
Regarding the show's incestuous subtext.Even for an older sister, Dee Dee is rather... attached to her baby brother. She's very touchy-feely, tries to distract Dexter from his work all the time, and gets upset when Dexter ignores her. He's the only character she treats this way, and it evokes a girl who's too into her love interest. The creators of the show probably wanted a kind of reclusive guy, extrovert girl plot...except that Dexter would be too aloof and preoccupied to catch on to her advances. In the end, they decided to just make the two siblings, probably to explain how she's always at his house if he doesn't like her much. But they kept the trappings of a one-sided romance.
Dee Dee is Eris from The Grim Adventures of Billy & Mandy.A younger form? An avatar? A daughter? A herald? Whatever she is, there's nothing better to disrupt the delicate machinations of science and technology than the divine powers of chaos and discord. If she grows up to be a total babe with an accent as inexplicable as her brother's, well... no surprise here.
Dee Dee is not Dexter's sister, but his future daughter.Some time in the future, Dexter has a daughter but also creates an invention which threatens the world. Dee Dee is sent back in time to prevent this from happening by pretending to be his sister and destroying his inventions that could set up her future. She can get into Dexter's lab no matter what protections he puts on it because, to her, they've always been there; she knows how to bypass them. And Dee Dee is a codename, literally standing for 'Dexter's Daughter'.
- Ego trip may be the idea that Dexter in the future finds out about her plans and wants to stop her. When the robots are sent, Dexter destroys them, and then the rest of the plot follows up to the other Dexter's sending their own wave after Dee Dee.
- Alternatively, they're opposite sex clones. Either she's from the future, or Deedee used to be a supergenius, but in the experiment that produced Dexter, her advanced knowledge got transferred to him, and she became a massive ditz). She's able to bypass the security features because, as far as the security features know, she is him.
- As far as we know, Dexter could be some sort of technological Haruhi, and Dee Dee is there to stop him. Except that he won't grope her. Eww.
- Dee Dee's Dexter's granddaughter; that's why she called him gramps when he was old in that episode. It's because he is her grandfather.
Dexter is Dexter from Dexter.What? He hates people, is super smart, and has an oblivious sister. It makes everything slightly less confusing.
- I like this one, but it is immediately jossed by the fact that Dee Dee knows about the lab, while Deborah knows nothing of Dexters "hobbies". can this hole in the theory be patched?
- So, wait, does that mean Mandark dismembers hookers?
- His parents named him Susan, who's surprised?
- Alternatively he buries boys, slices young women in bathtubs, throws family mothers from bridges and blunts family fathers to death with hammers. In this order.
- Dexter has red hair, trouble fitting in with normal people, above average intelligence, talks to himself constantly, and clearly feels some level of disgust with the world around him.
- Perhaps the "secret lab" under his house is really just young dexter's way of referring to the basement where he butchers animals.
- Dee Dee is obviously a nickname, short for Deborah, Dexter's childish and easily-excitable sister.
- As for Dexter's taller, thinner, dark haired evil counterpart, that would have to be Mandark. Obviously no young man would want to go through life with the name Susan, so he switches to Brian later in life.
- Dexter's accent is obviously an affectation, as no members of his family share this accent. Presumably he drops it once he begins to mature. The show Dexter's Lab is set before Dexter's 'dad', Harry, realises exactly what his son has been doing down in the basement.
- So, wait, does that mean Mandark dismembers hookers?
- Continuing on from the above troper's guess, Dexter's Lab is seen from Dexter's point of view as a young child, hence the cartoony style, lightheartedness, and no hint of Harry not being Dexter's real dad.
- Alternatively, Dexter and his family were on a drive home from a vacation to Miami but they crash and only Dexter survives. The crash had traumatized him (which explains why he's so f$#@ed up), but his vision improves (which explains why he no longer wears glasses). He later gets picked up by the police who take him to an orphanage, gets adopted by the Morrigans, and the rest is history.
- Honest Trailers already made a parody video about this.
Dexter's Lab is the prequel to The Big Bang TheoryThis says it all
Dexter is a leprechaun, or a Half-Leprechaun.He's short, red-haired, and does things that defy the laws of physics. Oh sure, he calls it "science," but he never once employs the scientific method. His uncle uses real magic and is clearly Irish.
- In Ego Trip, his future self is a giant, which kind of josses this.
- Tall leprechauns have been seen in numerous settings. Joss denied.
- Like in The Life and Times of Juniper Lee.
- Tall leprechauns have been seen in numerous settings. Joss denied.
Dee Dee's smarter than she's letting on.
- She's never seemed dumb by any stretch, just playful and hyperactive. It takes a level of brains to regularly bust into Dexter's lab.
- Agreed. Recall that she mastered general relativity before Dexter himself did.
- Deedee knows exactly what she's doing - the pilot episode where she has to check if Dexter's ready for school will show it (knocking on his door and asking if he's ready in such a quiet way that he wouldn't hear her even if he wasn't in his lab, and whipping out a credit card to open his locked door without batting an eyelid).
- Dee Dee is smart, but she wants to enjoy every moment of her life. She breaks things in Dexter's lab because she knows he is spending all his childhood locked away from the world. She is smarter than she looks.
- Then that means Dexter didn't make her smart in the science project episode, he just removed her hyperactivity so she can focus her intelligence.
Deedee is cosmically aware.This kinda makes her a bit of a jerkass because she knows exactly what Dexter or anyone else means or is trying to do and still goes out of her way to be the ditz.
- Or she can see the future and knows that if Dexter continues doing what he's doing, he'll destroy the world.
Dexter is a Son of Ether.Seriously? Why is this even a theory. Unless magic was involved, I seriously doubt any of the stuff Dexter builds could have been built by a 8-10 year old.
- More likely he's a Neid Artificer or Atomist, quite possibly an Unmada or even Illuminated.
The nut Dexter's often seen turning indefinitely is a wind-up system to power up his lab.He designed a huge, complicated power generator that would be able to provide days' worth of energy for his gigantic lab by expanding the energy generated by that simple turning motion.
Dexter's dad is who Owen is during his off timeThat means that Dexter's Dad is one of the Children of Oberon...which actually explains a lot about Dee Dee and Dexter.
Dexter becomes the Professor from Jump Start 3rd GradeAnd Polly is his daughter. They do kind of look alike...
Dexter's family name is DexterThis is why they call themselves the Dexter family.
- So, you're saying Dexter's full name is Dexter Dexter? Or Double D for sho- My god.
- We've seen him in the Powerpuff Girls via cameo, at Pokey Oaks. Not to mention Major Man exists in both shows.
- But he was also in Time Squad, and is known for his genius as Larry and Tuddrussel brought him to try and figure out what the hell they're supposed to do with Columbus.
Dexter is living in a projection of his insecurities.Dexter, in reality, gets terrible grades in school and is not very bright. He envies the students that do well, and has grown jealous of them. This is why much of what he says is random technobabble, the amount of Cow Tools in his lab, and why none of his experiments seem to have any purpose other than BEING "scientific things": It's all in his head. Dee Dee is actually an Honors student, and because of Dexter's jealousy, she appears in his fantasies as an idiot. Mandark is the head of Dexter's class, and as such, gets the role of Dexter's rival. Mandark's lab is what Dexter really imagines him to have.
Dexter goes on to work at Black MesaAfter moving out of his house to perform his experiments away from Dee-Dee's meddling, Dexter realizes he has to change his name to escape the stigma attached to his old one that came about as a result of his lab being exposed to the public. He changes his name to Gordon, after his favorite show, Flash Gordon, and changes his last name to Freeman because he will finally be a Free Man. To further mask his appearance, he also dies his hair a darker shade of red/Brown and grows a goatee. Using money made from Do D contracts at his existing lab, he attends MIT (Being unable to attend harvard for reasons that would later become a Mystery to everyone, even those involved. After Graduating, he moves to New Mexico and seeks out occupation, eventually settling for a laboratory not unlike the one he owned as a child... The rest is history.
Dexter is Calvin.Except he's an alternate universe version, in which he embraced science instead of just his imagination. Think about it: both of them are very intelligent children, and are highly imaginative - it takes some serious imagination to invent some of the stuff Dexter creates. Calvin invented a thing or two, as well (the Transmogrifier, for example) but lacked the resources to make it truly real. They both have non-human companions who they trust and look to for advice above anyone else (Hobbes and the Computer). And, both Calvin's and Dexter's parents are nigh oblivious about what their sons get up to when they're alone.
Deedee has a form of epilepsy that causes her to destroy laboratories
Mandark moves to DimmsdaleAfter turning his mom from a hippie to a gangster wannabe, Mandark decided he wold punish himself. He moved to a small town named Dimmsdale. He changed his name to Denzel because no adult man wold want to go through life with the name Susan. And he chaged his last name too Crocker because his old last name Astronominov was too hard to pronounce. Then he went to work at Dimmsdale Elementary School. Then he gets ready for a life unlike the one he had as a 16 year old.
- Actually, he had a different first name in his first appearance which was retconned to "Susan," so he probably has a different surname too; it totally be "Crocker."
- And it makes sense that even though we saw Crocker's "past", magic doesn't make time travel possible, only shows the godkid what could happen, so The Secret Life of Denzel Crocker was Timmy's perception of Crocker's childhood.
Dexter will work for the SCP Foundation in the future
Dexter has Asperger's SyndromeThis troper has it, and she sees aspects of it in him.
- The previous editor didn't elaborate much on this, but it actually makes a lot of sense the more you think about it. In fact, it could be that Dex has Asperger's or some sort of low to mid level Autism and the whole show was actually from his perspective. The characterization is all true, but everyone is suffering from character exaggeration because that's how Dexter thinks of them. Suddenly, some of the shows quirks seem more resonable:
- Don't forget that he also shows traits of being socially inept, has very narrow and specific focuses (i.e. his latest invention), often takes speech literally, etc... need I go on?
Dexter and Mandark both have a vague mental disorder that's connected to their intelligence.I can't think of a another reason why else these two boys sound vaguely foreign but have American parents. With Dexter, he sounds like a kid doing a bad/childish Austrian accent, while Mandark's could really be anything. Hell, I thought Mandark actually WAS foreign, with him looking Chinese(ish) while his sister had some sort of Mongolian look to her. This is completely thrown out the window when we finally see their parents and they happen to be completely white. (Seemingly, anyways.) It could be that Craig McCracken intended for him to be asian, but the new production team had different ideas. Whatever idea the case maybe, it reminds me of this disorder: http://en.wikipedia.org/wiki/Foreign_accent_syndrome
- Actually, I believe Mandark's dad is intended to be Russian and his mother Asian, as his mom is based off Yoko Ono (I think) and his surname is Russian.
Most of the episodes of the series take place in a simulation designed by Dexter to determine everything that might go wrong with his laboratory before he gets too far into building it.This explains the Negative Continuity as well as why Dexter, who's supposed to be a genius, keeps messing up. He's doing it on purpose to test his future lab.
Mandark is a Hero AntagonistWe're just seeing things from Dexter's point of view.
- "Sun, Surf, and Science" is focused completely on Mandark, and he's shown in a more sympathetic light than usual.
- I always thought that depending on where you put the focus, either one would look like the villain.
"Dee Dee's Room" is just a nightmare of Dexter'sThat episode is surreal even by Dexter's Lab standards.
Dexter moved up a grade or twoEverybody in his class looks older than him, and he is a super-genius after all.
- That also explains why Mandark (who looks older than Dee Dee) is in the same class as him.
Seasons 3 and 4 are an Alternate ContinuityThere are just so many retcons this has to be true.
Dexter's accent is fakeDexter's family seems pretty All-American, and he's the only one with an accent. This is because he saw geniuses on TV and thought that all geniuses had accents. Also, this further helped to differentiate him from his family, who are idiots when compared to him. So he faked his accent until it became natural.
Dexter is also running a Meth LaboratoryAnd the one reason why Dee Dee keeps going inside the Lab and breaking Dexter's machines is to find the Meth.
- OW MY CHILDHOOD
Dexter is somehow the final regeneration of the Doctor
- And that explains the size of his lab and the Timey-Wimey Ball nature of "Ego Trip"
- He's finally a ginger!
- This explains why his lab in his bedroom is bigger than the whole house.
- Dexter Who?
Dee Dee's name is not "Dee Dee"It's a nickname.
- If I remember correctly, Dee Dee (or variations) is a shortening of Dierdre in the same way Bob is a shortening of Robert.
The lab isn't actually inside the house.It's located somewhere else and connected to Dexter's room via portal technology.
- Or it might simply be underground.
- One episode, the one where Dexter shrinks his parents and the whole house so that he can observe them, suggests that he uses portal technology: there's a door at ground level, you can see the inside of the lab, but there's no other structure.
Dexter is asthmatic.Think of it. During the VERY first episode, Dexter started to cough, and then used an inhaler.
The secret password to get into Mandark's laboratory is...Ha Ha Ha Haha Haha Ha! Ha Ha Ha Haha Haha Ha!
Dexter's parents are not his biological parentsHe was accidentally Switched at Birth. His biological parents are Hugh and Lila Test, also Susan and Mary are his sisters that means that Dee Dee's real brother is Johnny
- Alternatively, his real parents could have been those two scientists that looked like his mother and dad who were seen in that one episode where Dexter gets lost in the store, and their hyperactive son Dextor could've been Dexter's family's real son.
Dee Dee is smarter than Dexter.In the intro, you see Dee Dee roll her eyes and plug in the machine. That might seem minor, but in another episode, you see her hit buttons on Computer until she tells Dee Dee where Dexter is, and then she goes to rescue her brother. And when he insults her, she sends his pathetic ass back. My theory is every machine she destroys is either one that will malfunction horribly and/or one that will shatter the masquerade. So why does she hide it? Dee Dee is more socially adept, more athletic, and more popular. If Dexter knew she was also smarter than he was, he'd hate her. And nobody likes being hated. So she hides her intelligence to keep a relationship with her brother.
Dexter and Dee Dee are both altered clones of Helen Narbon Sr.In Dexter's case, she altered his sex, in case of Dee Dee, she enhanced her dexterity, flexibility, speed and reaction time. Dexter already went mad, Dee Dee will do so shortly, join her brother, make contact with Helen Narbon Jr and work on plans to conquer the US.
Lalavava, Mandark's sister, only appears one episode because...Mandark killed her! He than erased his parents' and his own memory of her ever existing.
Lalavava was created by Mandark in secret.He either cloned himself or recombined his parents' DNA to make his own sister, possibly as an assistant. Obviously this wouldn't go over well with his parents, so Lalavava lives in his lab and isn't allowed to tag along on family escapades with Mandark and his parents, explaining her absence in future episodes. Also gives her a Freudian Excuse for treating Mandark terribly.
Mandark is a trans boy.His backstory functions almost exactly like a trans kid's story (given a girl's name, dressed as a girl, laughed at for identifying as a boy, changing his name and appearance to be more masculine, and defending his masculinity while painfully hating the way he was raised). Since "A Boy Named Sue" is told as a backstory, one could invoke Unreliable Narrator to say he changed a few details to hide this fact, instead looking like a cis boy raised like a girl instead of a trans boy.
Dee Dee is evilShe knows that Dexter could better the world if he ever kept his lab up and going, and ensures that good cannot be done there.
Dexter's teacher Mr. Luzinski is Thaddeus Plotz.Both of them look alike, especially when compared to Mr. Luzinski's design in the older episodes, and both were voiced by Frank Welker using the exact same voice. The stress of running Warner Bros. Studios with Yakko, Wakko, and Dot running loose eventually became too much for Plotz, so he resigned and decided to start teaching elementary school. He had his name legally changed to lower the chances of the Warners ever finding him and ensure that he'd never be bothered by them again.
Dee Dee secretly likes Mandark.She just isn't open about it because she's afraid of her friends teasing her for liking such a nerdy guy. Given how, uh... flirtatious she sometimes acts with the equally dorky Dexter, her interest in his science stuff, she may well be attracted to Mandark's intelligence.
Dee Dee has a disease that will shorten her life considerably.She probably won't survive to her adulthood (one of the reasons why Dexter never met her future self in Ego Trip). The reason why Dee Dee is so keen in spending time with Dexter, beside her worry that he is wasting his childhood and life away by locking himself like he does (canon, as she said it in the "Way of Dee Dee") or why, in the episode when she was sick, their mother practically forced Dexter to read to her, is because Dee Dee is going to die soon. And Dee Dee knows it. The parents don't tell Dexter because, while he is a genius for certain things, he is still a little boy and there are things you don't know how to explain to a child. As for Dee Dee, rather than telling Dexter about it, she will rather try to enjoy whatever time she has by playing and living to the fullest (even if Dexter could find a cure, it would take exams and tests and she wouldn't want to waste her time like this). Also, maybe she doesn't want him to regret never spending time with her after she dies, so she will go play in his lab to be near him.
The reason why Mandark, on the future, became an evil overlord...Is that Dee Dee died. Think about it. As a child, he wanted to surpass Dexter and prove he was smarter. Understandable. As another person mentioned above, perhaps he isn't even a villain since the show is from Dexter's perspective... To go from such a normal goal from conquering the world, something must have happened. What? Dee Dee died and Mandark probably blames Dexter for it.
Dee Dee has supernatural powersShe has seen some insight into the future and also knew that her brother had been kidnapped without having seen it (when they were playing at the Chubby Cheese), seems to be able to communicate with animals and is friends with beings from another dimension (she remarked that Koosie isn't imaginary when he appeared the first time, so he is either from another dimension or she virtually made him real with magic, not different from Maria did to Sakutaro in "Umineko No Naku Koro Ni") and has show to be smarter than she lets on.
