''Dragon Ball'' started in 1984 and ran until 1996, and it is stated by several authors (including Masashi Kishimoto) that it served as a major inspiration for their own works (and given that ''Dragon Ball'' [[TropeCodifier codified]] several modern Shonen tropes, it shows).

** '''Implementation:''' Like the previous duel between ''Manga/DragonBall'' and ''Naruto'', both are manga series from [[Magazine/ShonenJump Weekly Shonen Jump]]. In theory, they're fairly different given their different settings, but in practice both revolve around cool abilities and fights, with a villain that starts as PluckyComicRelief before revealing his true nature and sparking a global war. It's {{Shonen}}, there's only so much that changes from the formula. Also, the dueling pair gives us a meta pirates vs. ninja, which might have been started from the competing fandoms. Curiosly, as both series star regularly in Shonen Jump crossover games, this pirates vs. ninja is a popular choice of match.

** '''Implementation:''' ''Sweet Blue Flowers'' takes a rather serious approach, which deep insights into the minds of the characters, interspersed with some comedy. ''Sasameki Koto'' is more of a SliceOfLife comedy, although it has its share of serious moments as well.
----
* ''Anime/PrettyCure'' (2004) / ''Toys/{{Jewelpet}}'' (2009)
** '''Capsule Pitch Description:''' MagicalGirl shows that reboot with every new season. Both have cute, snarky mascots.

** '''Implementation:''' ''Aquarion'' sways more to the SuperRobot size and contains lots of fanservice and innuendo in contrast to ''Eureka'' which is mostly RealRobot and less in need of censorship.

** '''Implementation:''' Most obviously, the two series are aimed at different demographics (''The Idolmaster'' appeals to both boys and girls, while ''Uta no Prince-sama'' is more focused toward girls). ''Uta no Prince-sama'' also has quite a bit of yaoi subtext compared to the yuri in [=iM@S=].

His actions mean he [[VillainProtagonist may]] or [[AntiHero may not]] be a villain. Features strong BlackAndGrayMorality.
** '''Implementation:''' Both shows premiered in Japan at roughly the same time, although ''Death Note'' was based on a {{manga}}. The tone of ''Death Note'' is somewhat [[DarkerAndEdgier darker, grittier and more realistic]] and features {{Shinigami}}, while ''Code Geass'' allows for occasional filler episodes, has [[LighterAndSofter somewhat more levity]] [[FamilyUnfriendlyViolence while still somehow being more violent]] and still quite dark,[[note]]mostly because ''Death Note'' goes heavy on the grittiness[[/note]] and features HumongousMecha.
----
* ''Anime/SkyGirls'' (2006) / ''Anime/StrikeWitches'' (2007)
** '''Capsule Pitch Description:''' Scantily clad young females operate fantastic flying machinery to fight creatures that copy the appearance of other things.
** '''Implementation:''' ''Strike Witches'' leans more toward the [[MoeAnthropomorphism Mecha Musume]] concept whereas ''Sky Girls'' has a more classical HumongousMecha theme. Both series feature character designs by Humikane Shimada and contain quite a bit of {{fanservice}}, although ''Strike Witches'' really ups the ante by giving none of the girls any pants. Both [=OVAs=] were created at roughly the same time, though ''Sky Girls'' was turned into a TV anime first.
----
* ''Anime/GRGiantRobo'' (2007) / ''Anime/{{Raideen}}'' (2007)
** '''Capsule Pitch Description:''' DarkerAndEdgier, CG-enriched remake of classic GiantRobot franchises.
** '''Implementation:''' It can't be a coincidence that these two shows launched within mere weeks of each other. They're very similar shows in many ways. They're also both very similar to ''Anime/RahXephon'', a series that was, itself, based on the original ''Raideen''.
----
* ''Anime/KotetsuJeeg'' (2007) / ''Anime/TengenToppaGurrenLagann'' (2007)
** '''Capsule Pitch Description:''' SuperRobot animes with TransformingMecha that work mainly on RuleOfCool.
** '''Implementation:''' They aired on the same season, Spring 2007, and both have a suprising large amount of common elements, even [[ThisIsADrill drills]]. However, ''Gurren Lagann'' keeps basically one-upping itself while ''Jeeg'' is a more standard MonsterOfTheWeek show, but it's the sequel of an anime from TheSeventies, hence being the "original".
----
* ''Literature/{{Baccano}}'' (2007) / ''Literature/{{Durarara}}'' (2010)
** '''Capsule Pitch Description:''' Both shows feature an EnsembleCast with many characters created by the same author, Ryohgo Narita and even takes place in the same universe. Both shows also feature gangs, organized crime and lots of action with some supernatural entities thrown into the mix.
** '''Implementation:''' ''Baccano'' mostly takes place in America during TheGreatDepression and is told in a [[AnachronicOrder non-linear storyline]]. Not to mention it is [[BloodierAndGorier more graphic]] [[{{Gorn}} in terms of violence]] than ''Durarara''. The latter, on the other hand, takes place in present day Ikebukuro, Japan and has a more straightforward and linear storytelling than ''Baccano''.
----
* ''Manga/{{Freezing}}'' (2007) / ''Literature/InfiniteStratos'' (2009)

** '''Implementation:''' ''Infinite Stratos'' has a much lighter tone and focuses more on the harem aspects of the story while ''Freezing'' is packed with nudity and gore. Both anime series aired their first and second seasons together. ''Freezing'' has the author's personal fetishes as fan service.

** '''Capsule Pitch Description:''' Superpowered teenaged boys join up with [[OrganizationIndex The Organization]] and partner with {{muggle|s}} girls and save humanity from equally superpowered enemies.
** '''Implementation:''' This appears to blatant copying, with ''Out Code'' being the shonen-er version of ''Code:Breaker''. The main difference seems to be the aims of their enemies: CB's BigBad wants superpower supremacy while OC's MadScientist wants to begin a huge BizarreBabyBoom. Also, the lead of CB has [[PlayingWithFire fire powers]] while OC's lead is [[ShockAndAwe electric]].
----
* ''Manga/KurokosBasketball'' (2008) / ''Manga/{{Haikyuu}}'' (2012)
** '''Capsule Pitch Description:''' {{Shonen}} sports series focusing mainly on the development of a high school sports team, notably a duo between the short protagonist and the tall dueteragonist, who work better together than individually.
** '''Implementation:''' Both series were serialized in Magazine/ShonenJump, and both series’ anime adaptation’s were made by Creator/ProductionIG. However, ''Haikyuu'' focuses on volleyball, while ''Kuroko’s Basketball'' focuses on basketball. Also, ''Haikyuu'' focuses on a declining volleyball team, while ''Kuroko’s Basketball'' focuses on a basketball team that had the misfortune to compete with many generational talents.
----
* ''Manga/BlastOfTempest'' (2009) / ''Manga/MagiLabyrinthOfMagic'' (2009)
** '''Capsule Pitch Description:''' {{Shonen}} fantasy series heavily inspired by classics of literature.
** '''Implementation:''' ''Blast'' draws its "Spirit Inspiration" from the works of Creator/WilliamShakespeare while a good part of ''Magi'''s main cast is named and modeled after "V.I.P.'s" from the ''Literature/ArabianNights''. Both manga had their debut around the same time, and their anime adaptations first aired on the same week and channel.
----
* ''[[VisualNovel/PhantomOfInferno Phantom Requiem for the Phantom]]'' (2009) / ''Anime/{{Canaan}}'' (2009)

''Phantom'' is about a young amnesiac man caught at the wrong place at the wrong time and forced into a crime syndicate. ''Canaan'' features a girl targeted by a crime organization and relies on the title character for protection.

** '''Capsule Pitch Description:''' A [[DeadpanSnarker snarky]] male highschooler (with IdiotHair) tries to deal with one girl possessed by a supernatural entity in each arc. Some instances can result into the main character into having some sort of UnwantedHarem throughout the story. Both anime also have the same character designer, Akio Watanabe.
** '''Implementation:''' ''Bakemonogatari'' is a show that is [[QuirkyWork somewhat hard]] [[MindScrew to explain]]. It's got vampires, superstitions and lots and lots of [[PungeonMaster wordplay]]. ''The World God Only Knows'' on the other hand, has a [[RomanceGame dating sim]] {{Otaku}} who is forced to date girls in order to remove the evil spirits within them thanks to [[DealWithTheDevil a contract with a demon]]. The latter is also more lighthearted than the former.

** '''Capsule Pitch Description:''' A snarky male highschooler tries to deal with girls possessed by supernatural entities in each arc of the story. He is often accompanied with a girl who is almost as snarky as he is. Also, lots of quips for both series.
** '''Implementation:''' ''Bakemonogatari'' has vampires and other supernatural enteties. ''Bunny Girl Senpai'', on the other hand does not deal with those things and is more mundane than ''Monogatari'', but there are still several supernatural phenomena thrown into.
----
* ''Manga/OnePunchMan'' (2009) / ''Manga/MyHeroAcademia'' (2014)
** '''Capsule Pitch Description:''' Manga that focus on worlds where superheroes are commonplace and work under a system. Following two heroes who try to rise in the ranks.
** '''Implementation:''' ''One Punch Man'' is a webcomic redone in a more professional style on the online site Tonari no Young Jump. It is more comedy oriented and a bit of a GenreDeconstruction as the hero, Saitama, is so massively overpowered, he barely finds any joy in superheroing. Even when he does, he barely if ever gets any respect for it save from a small handful of heroes. ''My Hero Academia'' started its run about 5 years later in Shonen Jump. Storywise it is the opposite, as the hero, Midoriya, starts out having no powers but is granted them from his idol. However, he is still quite panicky to use them effectively, and has yet to earn much respect from other so-called heroes with superior abilities. In both cases, however, their hearts are in the right place and they tend to fight for what's right rather than fame and glory.
----

** '''Capsule Pitch Description:''' Both are gaming-oriented {{Seinen}} series revolving around protagonists engrossed in the world of {{Fighting Game}}s and the MediaNotes/FightingGameCommunity during the Video Arcade Renaissance of the early-mid 1990s.
** '''Implementation:''' ''High Score Girl'' establishes itself as a SliceOfLife romantic {{dramedy}} about children [[ComingOfAgeStory growing into adulthood]] during the 90s, heavily employing the arcade gaming boom and the 3rd, 4th and 5th generation game console histories as a backdrop for the story.

** '''Capsule Pitch Description:''' Popular anime of TheNewTens that changed the face of the MagicalGirlWarrior genre.
** '''Implementation:''' ''Puella Magi Madoka Magica'' is a {{deconstruction}} of magical girl warrior shows, playing with common traits of magical girls like love, heroism, and friendship. A lot of the show's popularity comes from its shock value, with a deliberately cutesy appearance used to mask the CosmicHorrorStory it really is, and it is considered to be the BreakthroughHit of Creator/GenUrobuchi. ''Kill la Kill'', on the other hand, is a {{reconstruction}}, making fun of other magical girl traits like magical girl outfits and powers.

Their respective writers, Creator/GenUrobuchi and Takahiro (the creator of ''Manga/AkameGaKill'') are also known for their dark imagery and themes in their writing, and both anime are centered around hope. However, ''Madoka'' incorporates more psychological horror, dark imagery, and philosophical themes (like many of Creator/GenUrobuchi's works) while ''Yuki Yuna'' incorporates more SliceOfLife elements, is more light-hearted, and more character oriented. The characters in ''Madoka'' are brutally killed off while the characters in ''Yuki Yuna'' are kept alive.

Both series have their degree of a happy ending, [[spoiler:although ''Madoka''s case is more of a BittersweetEnding]].

''Sword Art Online'' focuses mostly on action scenes and JapaneseSpirit, while ''Log Horizon'' focuses on political intrigue and attempts to recreate modern technology. ''Log Horizon'' is [[LighterAndSofter more lighthearted]] than ''Sword Art Online''.

** '''Capsule Pitch Description:''' Both shows involve a "special" class of high school students who are given a target to assassinate by a certain time period. Also, they feature a blue-haired protagonist who is level-headed and competent at what they do.
** '''Implementation:''' ''Assassination Classroom'' shows a comedy sci-fi setting that involves students of E-Class trying to assassinate their octopus-like teacher before their graduation, while ''Akuma no Riddle'' features a serious, realistic setting about twelve students of Class Black trying to kill a girl named Haru Ichinose with one of them have defected to protect her.

----
* ''Manga/AttackOnTitan'' (2013) / ''Literature/BlackBullet'' (2014)

** '''Implementation:''' ''Anime/KillLaKill'' is an original anime series made by the same team responsible for ''Anime/TengenToppaGurrenLagann''. ''Manga/AkameGaKill'' is based on a manga. The female protagonists are [[AntiHero anti-heroes]] for different reasons: Ryuko has a more selfish goal of revenge against the person who killed her father, while Akame is a cold-hearted assassin who resorts to murder to topple the Empire and rebuild society. ''Manga/AkameGaKill'' is considered to be DarkerAndEdgier than ''Anime/KillLaKill'' because the former has [[AnyoneCanDie a higher death count]] while most characters in ''Anime/KillLaKill'' either are knocked out or receive ClothingDamage at worst. ''Anime/KillLaKill'' incoporates more quirkiness (such as the theme involving clothes) and comedy, while ''Manga/AkameGaKill'' incorporates more TearJerker and drama.

** '''Capsule Pitch Description:''' MerchandiseDriven collectable card game anime adaptions.
** '''Implementation:''' ''Arc-V'' is a sequel to the long standing Yu-Gi-Oh! series aiming at children. ''Wixoss'' is JC Staff's adaption of Takara Tomy's card game aiming at male adults. Both deconstruct a number of elements from previous entries of the genre.

** '''Capsule Pitch Description:''' AnimeFirst {{Mecha Show}}s featuring UsefulNotes/{{Mars}}, [[PoliticallyActivePrincess a princess]], and an emotionally stunted main character that deconstruct a lot of RealRobotGenre tropes. Both shows take place [[CataclysmBackstory in the wake of a disastrous war in the past]] and are a more realistic take on real robots and super robots. Both shows also heavily pitched the fact that they had some serious star power in the form of their writers: Creator/GenUrobuchi for ''Aldnoah.Zero''[[labelnote:*]]At least for the show's basic background and the first 3 episodes[[/labelnote]] and [[Anime/NagiAsuALullInTheSea Mari]] [[Anime/AnoHanaTheFlowerWeSawThatDay Okada]] for ''Iron Blooded Orphans.''
** '''Implementation:''' ''Aldnoah'' features a Martian invasion of Earth led by imperialistic Martian colonists who want to plunder Earth's natural resources. ''Iron Blooded Orphans'' is about a Martian [[PrivateMilitaryContractors PMC]] group made up of ChildSoldiers trying to escort the leader of a colonial independence group to Earth to negotiate for greater colonial autonomy with a corrupt military organization standing in the way. ''Aldnoah.Zero'' flips the premise of the RealRobotGenre by putting the hero in a [[MechaMooks basic training unit]] and showing how [[WeakButSkilled good planning and tactics]] can [[RockBeatsLaser defeat advanced technology]]. ''Iron Blooded Orphans'' gives the hero [[LostTechnology advanced technology]] but [[DisasterScavengers limited resources]] with [[UnskilledButStrong little formal training]].
