* SugarWiki/AwesomeMusic: The guitar duel between Bob and Megabyte in season 1.
* BadassDecay: Matrix in season 4.
* BellisariosMaxim: Not everything about this computer world really makes sense as related to how we use computers. It is just an interesting setting, as well as way to bypass fan comments related to the computer limitations. Like "Why are there no shadows?" "Uh...It's inside a computer!"
-->'''Hexadecimal:''' Nevermind, it will be glorious!
* ClicheStorm: Certain episodes have their plot built on a long string of cliches, but it is either done as an AffectionateParody or otherwise knows what it is doing.
** {{Troperiffic}}
* CompleteMonster: [[BigBad Megabyte]], an order-obsessed virus, becomes one after season 2. While in previous seasons Megabyte had a personal code of honor and was [[AffablyEvil affable enough]] to give Enzo a birthday present, after a forced FusionDance, he loses those qualities, as shown when he uses an EldritchAbomination's invasion as a way to trap [[TheHero Bob]] in an EldritchLocation. With Bob out of the way, Megabyte turns his attention on capturing Mainframe, with the end goal of infecting the Supercomputer and the entire Net. To that end, he lets his sister Hexadecimal get crushed with the [[ThereIsNoKillLikeOverkill side of a game cube]], then has her rebuilt with a shock collar so she is forced to power his death ray. He makes it incredibly difficult for Enzo to continue beating game cubes, dooming thousands of binomes to a FateWorseThanDeath and causing untold destruction for the sake of driving the kid into a HeroicBSOD. When he gets into the Central Office, he decapitates [[{{Mentors}} Phong]] and [[ColdBloodedTorture tortures his severed head]] not only for information, but for his own sadistic amusement. His minions, Hack and Slash, are terrified of him, and he often [[{{Fingore}} breaks Herr Doctor's fingers]] as punishment. Even after being defeated, he's caused so much damage Mainframe can't recover and the heroes are forced to deliberately [[CessationOfExistence cause a crash]] for a chance at rebirth. Later, he returns to Mainframe and [[spoiler: impersonates Bob]], turning everyone against Glitch-Bob before proposing to Dot and almost marrying her for no reason other than [[ItAmusedMe to amuse himself]]. He is willing to hurt anyone and everyone for [[ForTheEvulz his own petty amusement]].
* EnsembleDarkhorse: Hexadecimal.
* EpicRiff: The episode dealing with Enzo's birthday sees Megabyte roll up with an electric guitar and play an absolutely [[SugarWiki/AwesomeMusic face-melting solo]]. It then turns into a [[ThePowerOfRock Power of Rock]] showdown between him and Bob for even more epicness. Megabyte even lampshades how awesome the whole thing is.
-->'''Megabyte:''' "I've always wanted to do that!"
* EpilepticTrees: Quite a few fans like to believe that Megabyte and Hexadecimal merging is what caused Megabyte to become more vile, crazy, and dangerous later in the series. It would certainly explain the stark contrast between "give Enzo a guitar" Megabyte of season 1 and "try to commit genocide" Megabyte of season 3 but that's about the extent to which it makes sense.
* EvilIsCool: '''Megabyte'''. Everything about the character just exudes frightening badassery, from [[Creator/TonyJay his voice]] to his look.
* EvilIsSexy: Daemon qualifies for this. Also Hexadecimal, [[spoiler: until her HeelFaceTurn later on.]]
* FamilyUnfriendlyAesop: Little!Enzo tells [[spoiler:Infected!Matrix]] to embrace his hate and use it to defeat Daemon.
* FanonDiscontinuity: Some fans leave out season 4, due to the somewhat disappointing conclusion to the Daemon arc (see HypeBacklash below) and the fact that it, and thus the show, ends on a massive cliffhanger (contrasted with season 3, which gives a pretty satisfactory ending due to the fact that [[SeriesFauxnale it was originally intended as such]]).
* FoeYay: Bob and Hexadecimal, with Hex seemingly unable to decide if she wants to kill him or flirt with him, [[spoiler: and after her HeelFaceTurn, she kisses him and performs a HeroicSacrifice to save him and Mainframe.]] As well as Dot and Megabyte, [[spoiler: with Megabyte posing as pre-glitch Bob to trick her into marrying him, and even forcing a kiss on her.]]
* FunnyAneurysmMoment: Megabyte and Matrix's brutal fight at the end of season 3 makes the earlier moment where Megabyte gives Enzo a guitar for his birthday seem a lot less funny than it originally was. Really, all of Megabyte's antics in the first season become a hell of a lot darker in tone after the later seasons.
** "Talent Night" in general. It's kind of depressing watching Dot plan so much for Enzo's birthday knowing that thanks to unfortunate circumstance, she'd miss getting to see him grow up completely.
* GeniusBonus: The more you know about computer hardware, computer software, computer programming and CGI the more entertaining the show becomes. Several character's names are rooted in technical terminology. In particular the character designs for Phong (phong shading) and Ray Tracer (Ray Tracing) actually demonstrate the CG principles they are referencing.
** There are a few, mostly relating to binomial sequences. The punchline to one joke is told in binary and when Daemon orders Deacon to recite Code 101. He proceeds to recite a series of binomial numbers; the code translates to five, four, three, two, one, [[OhCrap zero]].
** Daemon's name itself is its own genius bonus. A daemon is a background process which is why Daemon had such a passive process during her infection of the net, simply sitting back and monitoring all of her guardians is her function.
* GrowingTheBeard: The first two seasons were fun and entertaining, but excessively hampered by MoralGuardians that hindered the growth of a more mature show, they weren't allowed to cut to a commercial with someone in immediate peril (like falling off a cliff) for fear of upsetting the children. The final four episodes of the second season started up some more thematically interesting stories with a continuing storyline that fed through the rest of the series, which really hit its' stride in the first few episodes of the virtually censor-free third season.
* HilariousInHindsight:
** Nintendo announced that their next console would be called the "UsefulNotes/NintendoGameCube". The fact that the console's default color was ''purple'' did not hurt.
--> '''Mouse:''' "Wow! Now THAT'S what I call a bug zapper!"
--> '''Dot:''' "I don't believe it! We've been saved by a game cube!
** Another episode featured a brief gag (aired in 1997) that had a battleship called the SS Cameron catching fire and sinking. This was in reference to the obscenely overbudget fiasco of ''Film/{{Titanic 1997}}'' and what people were predicting of Creator/JamesCameron's career...
*** The number of VA's Reboot has in common with ''WesternAnimation/AdventuresOfSonicTheHedgehog''. In particular, for the first two seasons, Hack and Slash were played by the same actors who played Scratch and Grounder, also inept villainous robot mooks. {{Relationship Voice Actor}}s much?
** "I am become Gigabyte - destroyer of systems!" - terrifying until you find out there's a computer parts manufacturer with the same name- a ''creator of systems'' if you will. Go figure.
* HypeBacklash: The fourth season came out after being UnCanceled three years after the third season. With all the FanFiction and rampant WildMassGuessing from the fandom (with no expectation of ever ''getting'' a resolution), there were bound to be a few accurate theories and a few fanfics that proved to be a more satisfying conclusion for the Daemon arc.
* MagnificentBastard: Megabyte, ''Megabyte'', '''Megabyte'''.
* MoralEventHorizon: [[spoiler: Megabyte betraying Bob and banishing him from the Mainframe so he could take over.]] Especially cruel when one realizes that [[spoiler: [[UngratefulBastard the only reason Megabyte wasn't turned to dust years ago was because of Bob was certain that he could be redeemed]]]].
* SeasonalRot: [[PostScriptSeason Season 4]] is not as well-liked as the previous seasons, particularly the "My Two Bobs" arc (originally broadcast as a single TV movie). The fact that it [[LeftHanging ends on a cliffhanger]] makes it worse. The "Daemon Rising" arc is liked by some though.
* SeinfeldIsUnfunny: The CGI itself. It was mind blowingly cool when the show first premiered but was still very stilted and awkward because of the technical limitations. It didn't help that ''WesternAnimation/ToyStory'' premiered the following year with a film budget and time table that made some people believe that [=ReBoot=] was a cheap, inferior CGI product. This is in addition to the rampant ExecutiveMeddling that hampered the show. The truth is that this show and ''WesternAnimation/BeastWars'' laid the groundwork for CGI television and regardless of the technical limitations the story and scripting was of excellent quality.
* SpecialEffectFailure: Regrettably, animation goofs weren't only isolated to the first season where you'd expect it to be perfectly normal for the team and editing staff to get their bearings. Some silly things in plain sight seem to manage to slip past quality control, like virals having normal uninfected eyes, or character's anatomy interactions going a little bit haywire.
* SpiritualAdaptation: Of ''Film/{{Tron}}''.
* {{Squick}}: The nulls are slimy, multi-colored crosses between maggots and slugs that can make little noise beside a squeaky screech. Aside from Nullzilla which is FridgeHorror unto itself, there's a notable incident where an army of nulls devour one of Megabyte's Armoured Binome Carriers, with ''two henchmen still inside,'' and it's gone in seconds. Cringeworthy stuff.
* UncannyValley: Hex's Dot impression in the video game looks right, but maintains or even exaggerates Hex's signature walk with the swinging arms and the sashaying hips. FetishFuel turns into NightmareFuel when Hex's mask is removed in the form of Bob pulling off Dot's face, complete with squick sound effects.
** In the early seasons Dot especially came across rather doll like, which the creators commented on. Kathleen Barr's fantastic voice work helped minimize the uncanny valley, making her feel more lifelike.
* UnpopularPopularCharacter: Mike the TV. In principle, could easily fall into a number of [[TheScrappy scrappy]] tropes, but he is considered obnoxious by pretty much everyone else in the show. This made his antics skew on the side of endearing to the fans rather than smug goofiness. It helped too that his introductory episode had him rebooting in a game where everyone had to work together to win, and Mike did his part admirably.
* SugarWiki/VisualEffectsOfAwesome: At the time, at least, pretty much every part of Reboot was this. Now, [[TechnologyMarchesOn not so much]]. Several of the models still hold up well though, at least when they aren't moving, and the [[EpicTrackingShot crazy camera movements]] proved what an AllCGICartoon could do. The ArtEvolution of the show is also fun to watch.
* VillainDecay: Inverted. Over the course of the series, Megabyte became progressively more dangerous and went from concocting subversive schemes to [[TheBadGuyWins eventually taking over Mainframe and preparing an invasion of the Supercomputer]]. Even when the heroes seemed to have defeated him at last, Megabyte comes back in season four; stronger than ever [[ForTheEvulz and completely psychotic, to boot]]. He's still as vicious and cunning as he was in the past, but now has the ability to impersonate binomes and sprites. Oh and any sense of restraint or morality he ''may'' have had before is now [[OhCrap totally gone]].
