History Manga / Gamma

''Gamma'' is an ActionAdventure manga by Ogino Jun that borrows heavily from all manner of SuperHero and YuriGenre plots.

* AluminumChristmasTrees: [[InvertedTrope Inverted, in an odd way,]] InUniverse; the Kitajishi sisters are shocked at the idea that there was once a time when superheroes, mecha, and giant monsters only existed in movies and TV shows; upon seeing some for the first time, they briefly assume that they're documentaries.
** In particular, Miyuki finds the idea of movies featuring giant monsters being made for entertainment to be "sick," since the world regularly has to deal with the actual consequences of such creatures existing. [[spoiler:Mr. Lostman, who's showing the sisters his old movie collection, explains that said films are from a time before giant monsters actually existed]].

* APupilOfMineUntilHeTurnedToEvil: [[spoiler:Sakaki began his career as Mr. Lostman's sidekick, though it's left ambiguous if he only became evil later on or was EvilAllAlong.]]

* AscendedFanboy: [[spoiler:Mr. Lostman, who idolized fictional superheroes before acquiring superpowers for real. This is what motivated him to use his powers to become Earth's first real-life superhero.]]

* MassSuperEmpoweringEvent: The war between two alien races that flooded the planet with Lambda energy, which has been [[SuperpowerLottery randomly augmenting]] the life energy of all living beings on Earth. This empowerment is temporary, however, kicking in at different ages in different people and lasting them for a few years, at most.

* MeaningfulName: Yuri's secret identity is named Lily Cure, "Lily" being the English translation of her given name (not to mention that she is about [[YuriGenre as straight as a rainbow]]). Similarly, the given name of Lightbright's civilian identity is Hikari, meaning "light" in Japanese.

* MsFanservice: Hard to choose any one girl as they all get a chance to show off their bodies, but Hikari, AKA Light Bright, with her form fitting VaporWear outfit probably takes the most amount of {{Fanservice}}.

* ShipTease: Quite and bit between Miyuki and Yuri- see IncestSubtext- but also a lot between [[spoiler: Miyuki and Hikari as well as Yuri and Marina, which are the OfficialCouple[=s=] at the series' end.]]

* WhamShot: The end of Chapter 7, when it's revealed that [[spoiler:the mysterious man responsible for the both the recent string of monster attacks and Discharge's death is Kyosuke Sakaki, a captain in the EDF.]]

* HeroOfAnotherStory: Almost the basis for the series. A large number of heroes are introduced but they all have off-screen relationships, back stories, and battles and most of what's shown is just their interaction with the main characters and their story. Plays with AnyoneCanDie a bit in that several of these heroes have tragic backstories or have lost friends. [[spoiler: Also Sakaki is shown to have killed off a large number of other heroes before implementing his final plan. Thankfully he seems to have missed a few more than he thought.]]

* HotterAndSexier: Volume five, containing the MythArc conclusion, really ups the ante in yuri fanservice.

* BadassNormal: Miyuki has never had powers, but is an extremely skilled swords-woman.

* BroughtDownToNormal: Being a superhero is a time-limited deal, so they only get to use their powers for five years, tops. Most end up burning through their powers in a year or two. [[spoiler:Averted with Mr. Lostman, the first superhero, who soaked up so much Lambda energy that he kept his powers until his death, aged 75.]]

* RelationshiopReveal: [[spoiler:Chapter 16 reveals that, after much [[ShipTease teasing]], Miyuki and Hikari are romantically involved]].

* CastFullOfGay: Being a YuriGenre work there are very few females that are not obviously a lesbian.

* BadassCrew: Neo Mugen, a team comprising of the most powerful of Japan's superheroes.

** The Rock Rangers are a musically-themed take on Franchise/{{Super Sentai}} and Franchise/{{Power Rangers}}. When seen out of costume, the team members all heavily resembles the main cast of Series/KaizokuSentaiGokaiger.

** A more heartwarming one comes near the end of Chapter 16, when [[spoiler:Miyuki and Hikari lean in to kiss one another [[SexyDiscretionShot before the art cuts to an exterior of their hotel]], revealing that the two are officially romantically involved.]]

* EvilutionaryBiologist: [[spoiler:Sakaki.]]

* ClingyJealousGirl: Yuri, in a Tsundereish way, for her sister and as she gets closer to Marian she doesn't like that so many people have AffectionateNickname[=s=] for her.

* RetGone: [[spoiler:Midori, Miyuki's best friend and Yuri's partner/sidekick, sacrificed herself to save Lily Cure (presumably in the same incident that took the latter's powers), giving up not just her life, but her entire existence ''retroactively''. Yuri is the only person who still remembers her, because she still holds a small portion of Lily Cure's powers.]]

* ShipTease: Quite and bit between Miyuki and Yuri- see IncestSubtext- but also a lot between [[spoiler: Miyuki and Hikari as well as Yuri and Marina, which are the OfficialCouple[=s=] ate the series' end.]]

** A more heartwarming one comes near the end of Chapter 16, when [[spoiler:Miyuki and Hikari lean in to kiss one another

* BaitAndSwitchLesbians: A very odd case, [[spoiler: for all their fawning, touching, and rather sensual interactions the Kitajishi sister's are not a couple and end up paired with other female characters at the series end.]]

** The Rock Rangers are a musically-themed take on Franchise/{{Super Sentai}} and Franchise/{{Power Rangers}}.

* ArmorPiercingQuestion: Zen Fujiwara/Flame Bane's backstory revealed that he first used his powers to brutally murder any villain he came across. He's outraged when he finds out that the public sees him as a villain as well until [[MoralityPet EDF agent Rei Nicole]] outright asks him how many people he's actually killed. He's notably taken aback as he admits that he hasn't been keeping track.

** Bulldramo is a walking ShoutOut to the [[ComicBook/IncredibleHulk Hulk]]. Chapter 17 even has a scene that copies Cap and Hulk's scene in the [[Film/TheAvengers2012 2012 Avengers movie]] down to the gestures.

* VictoryIsBoring: PlayedForLaughs; [[spoiler:after the final battle, the heroes who retained their powers have a ''lot'' more free time since there are no new villains or monsters appearing. Rider Mask Stag laments how he doesn't have anyone to actually fight; Yuri points out that he's basically complaining about the Earth being at peace.]]
* WellIntentionedExtremist: [[spoiler:Sakaki's ultimate goal is to empower all lifeforms on Earth with Lambda energy so Earth will never have to worry about being invaded by aliens again. However, he's a ''very'' nasty piece of work who has no problem murdering anyone who gets in his way, employs a pair of villainous psychopaths, and whose master plan will kill a massive amount of people.]]
