* AssPull: The citizens turning against the Megarangers comes out of absolute nowhere. Prior to this they never had a problem with the team, always praised them and showed full support. There was no set-up, they just suddenly hate them.
* SugarWiki/AwesomeMusic:
** [[https://youtu.be/3IREN9BxLz8 The theme song]] is very high-tension, sounds very much like it came from a modern-day video game, and is most certainly -- as the song will probably end up getting you singing -- "Mega, Mega, Mega!"
** All of the mecha themes count. [[https://youtu.be/9qe65aD7MS8 Denji Gattai! Galaxy Mega!]], [[https://youtu.be/XBING8yskbA Saikyou! Super Galaxy Mega!]] and [[https://youtu.be/Kfs67tkmzhA Ginga wa Mamore! Mega Voyager!]] are all very easy to get you pumping to the beat for the extremely awesome mecha at INET's disposal.
** [[https://youtu.be/PwDIMhTRwBA Don't Stop! Mega Silver!]] The instrumental version has a saxophone!
* BizarroEpisode: Episode 18. It involves Kouichirou meeting a forest spirit (in what is otherwise [[HowUnscientific a show about technology]]), a Mushroom Nezire with [[PlayingWithFire fire powers]], and a [[ArsonMurderAndJaywalking gag involving Miku comparing a cow's udders to Chisato's nipples]]. Oh! And Kouichirou becoming an AccidentalPervert when he runs into a girls' locker room.
* CatharsisFactor: Some members of the Nezirejia are so callous and evil that you cheer when they are inevitably obliterated.
** In the 16th episode, the particularly despicable Poison Moth Nezire is disgustingly gleeful about poisoning people, then throwing around the sickly, untransformed Megarangers. So when the kaiju battle is more in the Megarangers' favor, they make sure Poison Moth Nezire can spread his poison nowhere else; they carry him into space and blow him up there with the Booster Rifle, ensuring that his death will not endanger any more lives, which is something Poison Moth Nezire would've been happy about.
** Episode 23 has Anglerfish Nezire, who is on a pursuit for his little brother, Komutan, who has ended up in the real world. But he's not looking for Komutan because he cares for him; he's only looking for him to increase his power, and can care less if he is hurt. He doesn't even care that he's being protected by Kenta/Mega Red, and is disgusted that Komutan is friends with humans. Anglerfish Nezire does succeed in absorbing Komutan to gain the power to turn things to diamond, but Komutan eventually resists, escaping Anglerfish Nezire and attacking him to save Kenta. [[HeroicSacrifice But in possibly one of the biggest tearjerker moments of the series]], [[IHaveNoSon this results in Anglerfish Nezire declaring that Komutan is no longer his brother]], [[SiblingMurder before murdering his own sibling in response]]. [[LackOfEmpathy And the monster is so unfeeling about it that he]] ''[[LackOfEmpathy laughs at Kenta's despair.]]'' [[NoHoldsBarredBeatdown Kenta proceeds to beat the ever living hell out of Anglerfish Nezire]], letting out all his rage at this complete bastard of a Nezire for killing his friend. Even after Kenta has Riser Punched him within an inch of his life, Anglerfish Nezire is subject to almost nothing else but ''pain'' in the kaiju fight; while he does overpower Galaxy Mega, it takes him losing his antennae to Delta Mega for the satisfaction to really hit, as he has no power left to stop the Megarangers from forming Super Galaxy Mega. [[ImpaledWithExtremePrejudice All he has left is death by Super Galaxy Knuckle.]]
** Guirail's downfall is perhaps the crowning moment of catharsis in this series. After having to endure his most heinous schemes and even using Yugande as, for a lack of a better term, a human shield, it's safe to say that [[spoiler:when he was driven mad by the SuperSerum that Dr. Hinelar gave him, it was really fun to hear him scream in agony as he is betrayed, same as he did everyone else. This disappears when he becomes so insanely strong he can wreck Super Galaxy Mega, but it comes back when the Mega Voyager fires a freaking massive missile into him to destroy him for good.]]
* CompleteMonster: [[BigBadWannabe Action Commander Guirail]] is the cruel and self-serving deputy of King Javious I, sent to oversee Dr. Hinelar on the operation to take over Earth. A [[SlasherSmile constantly-grinning]], [[SmugSnake self-confident bastard]] whose defining features are his {{sadis|t}}m and disturbing love for underhanded tactics, he is a brutal, savage fighter who relishes in the pain of his victims. Although loyal to Javious, he repeatedly demonstrates [[TheUnfettered he'll go to any lengths to see that his job is finished]]. One of Guirail's most defining crimes is his love for using {{human shield}}s: his first scheme involved him ''[[WouldHurtAChild kidnapping children]]'' just to hide behind [[DirtyCoward in order to save his own skin from the Megarangers]] and tricked Mega Red into punching his much younger friend, using his horrified reaction to escape. Worse yet, Guirail likes to trick his own allies into being subjected to horrible experiments while being unconcerned about collateral damage. In a particularly low moment, he proves how far his cowardice extends when he shows how quick he is to catch his own "comrades" in the crossfire to gain an advantage. [[ManipulativeBastard After convincing his much more honorable ally Yugande to work together for the common cause]], Guirail tricks him into becoming an unwilling FusionDance partner, then makes him take the full brunt of damage when the chips are down against them both. [[EvenEvilHasStandards Even his own allies are revolted by how far Guirail is willing to go, and are more than happy to set him up to meet his own end.]]
* EnsembleDarkhorse: The Nezirangers, [[PsychoRangers for]] [[Series/PowerRangersInSpace obvious reasons]].
* HilariousInHindsight:
** At one point, Shun fell asleep in a computer while continually pressing the 'Delete' button. Later in Creator/MasayaMatsukaze's seiyuu career... what would be his most infamous words? [[spoiler:'''[[Manga/DeathNote SAKUJO!!/DELETE!!]]''']]
** This is a video game-themed ''Super Sentai'' series. Almost 20 years later, the sister franchise ''Franchise/KamenRider'' would also release [[Series/KamenRiderExAid a video game-themed series]], although in Ex-Aid case, the video game aspect is combined with a MedicalDrama story.
* LesYay: In Episode 6, Miku tells Shintarou, a boy who wants to date her, that she likes another person. When the other Megarangers ask who that is, Miku doesn't necessarily answer their question. Instead, she grabs Chisato's hand and goes to take her for tea, with Chisato being shocked and misinterpreting it as a romantic gesture directed towards her. It's a minor example as, later on the series, it's revealed that she likes Shun.
* {{Moe}}: Miku, the resident BigEater of the team.
* MoralEventHorizon:
** If using children as human shields isn't enough for Guirail, he most certainly crosses it to the point of no redemption when he uses Yugande, one of his own fellow generals, as a human shield in an attempt to save his own hide from the Megarangers' Super Galaxy Mega's finisher. [[spoiler: Yugande may have barely survived, but still...]]
** Arguably, you could say that Dr. Hinelar crosses it when he creates the Nezirangers [[spoiler: for the sole purpose of killing Javious.]]
*** Technically, he already crossed it as Dr. Samejima when he [[spoiler:experimented on his daughter Shizuka, and as a result sacrificed her for the sake of his experiment.]]
** Shibolena makes it clear that she will never be a good person when she and her [[MonsterOfTheWeek Rose Nezire]] enact a plan to turn children into carbon copies of said Monster of the Week. She makes it immensely personal when she forces Ruri, a friend of Chisato, to drink the wine that results in the transformation. And she does this all with a sadistic grin on her face as she preys on a literal child, intent on making her a monster.
* {{Narm}}: During Guirail's meltdown, the camera shows his feet in a puddle of yellow goo, making it look like he wet himself.
* NarmCharm: The [[GratuitousEnglish English version]] of the opening song, as featured in Episode 44.
* RetroactiveRecognition: People will know Masaya Matsukaze because of his voice acting career after his TV career via Megaranger.
** Shigeru Kanai is now a politician. He was first elected in the 2010s under the defunct Democratic Party of Japan.
* ToughActToFollow: Not the series itself, but rather, one of the specific arcs, the Neziranger Arc. The arc executed the PsychoRangers concept ''so'' well that Toei hasn't tried anything else like it since then - although evil rangers have been used since, a team in the same vein as the Nezirangers hasn't been made. Nowadays, if a team of evil rangers is used, either they'll be joining the heroes sometime after their debut (see [[Series/NinpuuSentaiHurricaneger the Gouraigers]]), they'll be dealt with in the same episode they're introduced (i.e., [[Series/UchuuSentaiKyuranger Jark Sentai GoIndaver]], Recycle Sentai Great Worldgers) or are [[EleventhHourRanger stand-alone rangers that join the team late in their series]] (i.e [[Series/BakuryuuSentaiAbaranger AbareKilller]], [[Series/KikaiSentaiZenkaiger Staceasar]], and [[Series/AvataroSentaiDonbrothers Don Murasame]], [[Series/OhsamaSentaiKingOhger Ohkuwagata Ohger]]).
