''Dexter and Monkey Master'' is a television series created by [[{{Walkyverse}} David Willis]], based on his comic series ''The Head Alien''[[note]], both of which only exist within the continuity of ''DumbingOfAge''[[/note]]. It follows the adventures of Dexter the Head Alien, a megalomaniac dictator from a distant world, and his beleaguered robotic henchman Monkey Master. It also featured a tie-in comic series from MKG that started in conjunction with season 3.

!!Contains examples of:
* AnimatedAdaptation: And consequently...
** CompressedAdaptation: "Wedding Smashers" cuts out several gags and a lot of the real wedding subplot from the comic. Fans are naturally split on whether it works or not.
* ArtisticLicenseHistory: Napoleon's height in "Time's Short".
* AscendedExtra: The Sensitive Scanner in season 2.
* AscendedFanon: Head Alien's nickname of "Dexter" started as a fan in-joke, seeped into the comics and became his name outright on the show.
** It originated in the fanfic "Love Hurts", when Head Alien got a girlfriend named Sandra to contradict Monkey Master's claim that he was a "bit of a dork" outside the workplace. Unfortunately, she got really obsessive over him (StalkerWithACrush levels of obsessive) and begun following him wherever he went. Head Alien tried various ways to escape her (the origin of the grappling-hook chase-scene, another in-joke in the fandom), including one where he just put on a trench coat and wig.
-->'''Sandra:''' Hey, there you are, Head Alien!
-->'''Head Alien:''' Head Alien? Who's Head Alien? I'm Dexter!
-->'''Sandra:''' ...''(removes his wig)''
-->''({{beat}})''
-->'''Head Alien:''' Fine, I'm bald. You happy?
** This lead to an inside joke among the fandom when wherever someone would mention Head Alien doing something, someone would inevitably reply "Who's Head Alien? That's Dexter." This eventually bled into jokey advertisements of the comics ("Join Dex--uh, I mean, Head Alien"), until it was established in the comics that Dexter was his real name and Head Alien his title, which he's ''[[InsistentTerminology very tetchy about]]'', to the point of threatening those who won't call him by title with vaporization. (Except his very close friends, like Monkey Master.)
* AuthorsSavingThrow: The mindwipe year. Led to a BrokenBase between those who were relived the DorkAge was over, those who ''liked'' the previous season, and those who didn't like it but thought the mindwipe was a cheap way out.
* BusbyBerkeleyNumber: Monkey Master somehow corrals a French regiment into one during "Time's Short".
* CakeToppers: Head Alien disguises himself as one during "Wedding Smashers" as part of his scheme to raid the wedding. It goes badly, ''badly'' wrong.
* CrossOver:
** With Robo-Vac in issue #49 of the comic.
** With Ultra-Car in a season 4 episode.
* DeadpanSnarker: Monkey Master, constantly.
* FanonDiscontinuity: Season 8.
* FreakyFridayFlip: Dexter and Ultra-Car in the crossover episode.
* GettingCrapPastTheRadar: At several points. But a particular standout occurs in "Time Travel Trouble" when they run into a college-age Dexter's mother, looking rather sweaty and disheveled as she emerges from a darkroom...followed by an equally overtaxed woman several moments later.
* HeyItsThatVoice: Dexter is [[WesternAnimation/TheCritic Jay Sherman]]!
** Monkey Master is [[ToyStory Stinky Pete]]!
* HistoricalDomainCharacter: Napoleon Bonaparte in "Time's Short".
* HypocriticalHumor: Dexter pointing out his clone's weakness is "''obviously'' his hypermassive overconfidence!"
* ItRunsOnNonsensoleum: The various doomsday devices. Especially the one that runs on ''shrimp'' in "Wedding Smashers".
** In "Time's Short" Dexter attempts to build one that's powered by human annoyance. He sets up his SeverelySpecializedStore to gather fuel. Unfortunately, the end of the episode reveals that [[spoiler: he never figured out how to harvest it, so the device could never have worked.]]
* ImprovisedWeapon: The bride in "Wedding Smashers", who manages to beat someone up ''with an ice sculpture''.
** After his alarm-clock disguise fails, Dexter chases off the FBI using only a spring in "Time's Short".
* LimitedWardrobe: Dexter's trenchcoat and cape.
* TheNapoleon: Dexter, lampshaded in "Time's Short" with him meeting the actual Napoleon for a fight.
* PaperThinDisguise: Dexter posing as an alarm clock in "Time's Short".
** The wigs in "Wedding Smashers".
** Several episodes have disguised Monkey Master as an actual monkey or ape. Somehow, it tends to succeed.
* ShoutOut: "Insert stale joke about Shirley [=MacClaine=] here!"
** The priest in "Wedding Smashers" is a pretty clear take-off of the one from ''ThePrincessBride''.
** The SeverelySpecializedStore in "Time's Short" is a take-off on the Cheese Shop sketch from ''Series/MontyPythonsFlyingCircus''.
* TimeTravel: Used in season 2's two-parter "Time's Short" and "Time Travel Trouble".
* TimeTravelTenseTrouble: From above mentioned "Time Travel Trouble".
-->'''Dexter:''' We've already met earlier... later... whatever.
* ThinkingOutLoud: Lampshaded: "What's the point of ''not'' saying things out loud?"
* VillainProtagonist: Dexter
* WeddingSmashers: "Wedding Smashers", naturally.
* WorldOfSnark: Some MoralGuardians have criticised the show for "cultivating a culture of snarkiness".
* ZanyScheme: All the time. ''Obviously'', the only way to get shrimp for a shrimp-powered doomsday device is to crash a wedding and raid the buffet.
** That time is sort of lampshaded -- Monkey Master tries to get Dexter to consider a more rational scheme (such as raiding shrimp farms), but Dexter's already set his sights on crashing the wedding.
** And then turns out to be justified, as ''there are no other shrimp in the entire state'', as shown through montage.
