* DramaticIrony: When Twilight confronts Dexter about the solution to Clover's conundrum, he calls her out on how Earth pony scientists has their work neglected because [[FantasticRacism they weren't unicorns]], Twilight responds that creatures who lack magic can't do much to study magic. Let's remember to [[ChildProdigy whom]] [[BadassBookworm she's]] [[TrappedInAnotherWorld saying]] [[GadgeteerGenius this to]], an incognito representative of another species without magic.

* ChildProdigy: Dexter. Even without revealing the full extent of his scientific abilities, his interest in science rivals that of ''Twilight'', and is able to solve an Equestrian concept called "Clover's Conundrum" that has baffled even the greatest scientific and mathnatical minds in Equestria for centuries.

* ChildProdigy: Dexter. Even without revealing the full extent of his scientific abilities, his interest in science rivals that of ''Twilight'', and is able to solve an Equestrian concept called "Clover's Conundrum" that has baffled even the greatest minds in Equestrian mathematics.

** Dexter's laser pen, which he used to torment Diamond Tiara, [[spoiler: helps him defeat a changeling that was a disguised as Cheerilee]].

** Twilight, after Dexter's solved Clover's Conundrum. She spends ''nine hours'' examining it, sending letters to and from an important professor, and teleporting about the library. She calms down after Rarity dumps buckets of water on her head... only to see Rarity accidentally erased the blackboard in the process. Then she remembers that Dexter was the one who wrote it, and waits for him anxiously at Pinkie's surprise party. And the morning after the changeling attack, Twilight slips back into her manic phase when asking about the Conundrum.

* PhysicalGod: Implied in regards to the alicorns. Most notably, Princess Luna is capable of actually perceiving and attempting to interact with Dexter when he is moving at 64 times normal speed (although he's still fast enough she can't make out his precise features or quite catch him) and effortlessly shrugs off warding spells she warned would leave most ordinary people in a coma for a month at best.

* LaserGuidedKarma: Literally. When Diamond Tiara mocks Dexter, he builds a laser pen that [[BullyHunter sets her crown on fire]]. Ironically, this was an accident rather than DisproportionateRetribution; Dexter just wanted to ruin the finish, he didn't realise that the crown was actually a fake.

* StealingTheCredit: After reading the proof to Clover's Conundrum Dexter left in her blackboard, Twilight excitedly starts sending the answer to as many institutions as she can and receives many excited responses awaiting for the method needed to reach said answer. When confronting Dexter about said method, Dexter points out all those institutions thought ''Twilight'' had been the one to solve the Conundrum, and accuses her (correctly) of this trope, knowing full well that had Twilight mentioned Dexter, an earth pony, had been the one to solve it, there would be far less attention, as earth pony mathematicians are rarely taken seriously. He promptly pokes holes in her speciesist logic and leaves her rattled, as while she has the proof, ''she can't explain the necessary math''.

* GenreSavvy: After Dexter stole the blueprints to his diagnostic machine, Luna puts tracking devices on the more advanced items Dexter left behind, in case they are also stolen by this super-fast colt. Dexter, however, would not be denied so easily.

* BadassBookworm: Dexter, who puts his skills to use against [[spoiler: the Changelings]].

* {{Expy}}: InUniverse, Dexter considers Pinkie Pie, with her [[NoSenseOfPersonalSpace extroverted]] and [[GenkiGirl excitable behavior]], her pink color, and blue eyes, to be one for [[AnnoyingYoungerSibling Dee Dee]]. This fills him with enormous amounts of grief, and he actually calls her Dee Dee on instinct

* TimeTravel: Dexter doesn't believe the claims that Luna and Celestia are immortal, and doesn't believe in Nightmare Moon. His solution? Build ([[ContinuityNod a new]]) time machine to witness and record the [[WrongGenreSavvy perfectly-normal day and prove the propaaganda false]]. [[spoiler: Predictably, it all goes to hell in a handbasket.]]

* HeroicSociopath: Dexter is frequently called a "borderline sociopath" in the narration. Knowing Dexter, he likely ''diagnosed himself'' as such at one point.

Let's remember to [[ChildProdigy whom]] [[BadassBookworm she]] [[TrappedInAnotherWorld saying]] [[GadgeteerGenius this to]], an incognito representative of another species without magic.

* FlatEarthAtheist: Dexter has the uncomfortable position of being a rationalistic skeptic in a world that genuinely does run on magical principles. Much to his discomfort as he keeps finding out that his "rational" assumptions are wrong and, yes, the ponies are telling the truth. His sheer level of skepticism arguably pushes him close to HollywoodAtheism, but he does make painstaking rational arguments. For example, even after being forcibly confronted with the fact that Equestria is a geocentric[[note]]sun and moon orbit the planet, rather than planet orbiting the sun[[/note]] world, he refuses to believe that the Princesses are responsible... because how could life have ever evolved over billions of years if two individuals have to physically control the sun and moon? He's still ''wrong'' in his assumptions, but his reasons for being skeptical are rational. He's just insisting on applying real-world scientific fact to a world that runs on magic.

* GenreSavvy: After Dexter stole the blueprints to his diagnostic machine, Luna puts tracking devices on the more advanced items Dexter left behind, in case they are stolen by this super-fast colt.

* {{Jerkass}}: Dexter is as antisocial and egotistical as per canon, but it really stands out among the residents of [[SugarBowl Ponyville]]. Highlights include insulting Equestrian history, and calling Pinkie Pie stupid.

* PhysicalGod: Implied in regards to the alicorns. Most notably, Princess Luna is capable of actually perceiving and attempting to interact with Dexter when he is moving at 64 times normal speed (although he's still fast enough she can't make out his precise features or quite catch him) and effortlessly shrugs off warding spells she warned would lead most ordinary people in a coma for a month at best.

* PragmaticVillainy: [[spoiler: The changelings don't go after the Elements of Harmony because they would lose their only defense against dangers like Sombra and Discord]].

* StuffBlowingUp: Dexter decides to perform a chemistry experiment with the CMC, and end up destroying Carousel Boutique. Rarity is [[{{Understatement}} not amused]]. And Twilight will not let Dexter anywhere near her lab.
