History VideoGame / MegaManZero

* BleachedUnderpants: Toru Nakayama, the main artist of the game, has at least 6 adult doujinshi to his name.

Another entry into Creator/{{Capcom}}'s popular flagship ''Franchise/MegaMan'' series, a DarkerAndEdgier direct SequelSeries to ''VideoGame/MegaManX'' for the UsefulNotes/GameBoyAdvance that continues the story of Zero, X's partner and best friend.

The series lasted for four games, the first in the franchise to be given proper closure. It would spawn a sequel series, ''VideoGame/MegaManZX'', which currently stands at two installments. A CompilationRerelease of the entire saga has also been released for the UsefulNotes/NintendoDS. Creator/IntiCreates later went on to develop ''VideoGame/{{Azure Striker Gunvolt|Series}}'', a {{spiritual successor}} to the ''Mega Man Zero'' series, and as their first independent video game series. Another compilation re-release, aptly named ''Mega Man Zero/ZX Legacy Collection'', was released in February 25, 2020 for [=PlayStation=] 4, Xbox One, Nintendo Switch, and PC through Steam, bringing the entire ''Zero'' and ''ZX'' series into one package along with new beginner-friendly features in the form of a Casual Scenario mode and a Save-Assist ability, optional CRT and smoothing filters, the Japan-only e-Reader Mod Cards for ''Mega Man Zero 3'' and Dual-Slot feature from ''Mega Man ZX'' implemented, a collection of music and artworks from both series, and a new Z Chaser mode where players can race against one another to quickly clear stages.

** Which is probably why the CompilationRerelease for the UsefulNotes/NintendoDS comes with an "Easy Scenario", an option to play through all four games in one go with all the weapons, items, and cyber-elves collected and maxxed out.

** The ''Mega Man Zero Collection'' for the UsefulNotes/NintendoDS, which adds an "Easy Scenario" Mode for beginners, fixed some of the translation errors, brought over the Japanese-only e-Reader Mod Cards from ''Rockman Zero 3'' in the overseas release, the ability to use the DS's X and Y buttons, and a gallery with unlockable images.

* BookEnds: The first and last major missions of the series are actually very similar; the major difference is the sense of scale. Both are timed boss fights against named Mavericks where innocent lives are on the line if the timer reaches zero - in ''Zero 1,'' it's three reploids that Aztec Falcon is trying to retire. In ''Zero 4,'' it's [[spoiler: all life on the planet in the long run, as Weil tries to ram his KillSat into Area Zero, the last bastion of nature (and thus oxygen) left after Neo Arcadia was blown to smithereens.]]

* CataclysmBackstory: The Elf Wars shaped the present world into a CrapsackWorld. The war has killed roughly 90% of reploids and 60% humans on earth in a span of 4 years. Dr. Weil and Omega were responsible.

* MookCarryover: Neo Arcadia's various Mechaniloid and Pantheon minions [[note]][[VidoeGame/MegaManZero1 Pantheon Hunters, Pantheon Guardians, Pantheon Zombies, Barrier Counters, Cannon Hoppers, Carryarms, Carrybees, Condoroids, Floppers, Garms, Gli-Eyes, Gyro Cannons, Hoppiders, Kerberoses, Seal Cannons, Securipiders, Sharkseals, Shellcrawlers, Spikings, Top Gabyoalls]], [[VideoGame/MegaManZero2 Molegules, Poplans, Saranets, Telly Bombs, Yadokroids]], [[VideoGame/MegaManZero3 Crossbynes, Lamports, and Shotloids]]. [[/note]] initially have Copy X leading them in the first game, before Sage Harpuia and later Elpizo in the second game, before settling on Dr. Weil for the third and fourth games.

* FantasticRacism: As a result of the discrimination, most mass produced reploids have NoNameGiven, being simply called by their designated serial numbers, like TK-31 or HE-22. It was Ciel who named most of the Resistance members, and she seems to [[ThemeNaming love birds]]. Shown more in the fourth game where most of the Caravaners distrust Reploids. Granted, they have been waging RobotWar for more than 2 centuries now...

** The firefly-producing mook in the Crystal Cave stage can help you traverse the confusing path of seemingly spike-laden area by revealing the invisible platforms around them.

** Zero was made by Dr. Wily as TheAntichrist. 2 ironies come from this: 1) [[spoiler:Omega (Zero), especially after powered with Dark Elf (read: a maverick antivirus that turns into a corrupting agent) is similar to Awakened Zero in ''X5'', i.e. what Wily intended Zero to become. Bonus points with Weil having similarities to Wily.]] 2) Zero ends up being the savior of the world, in the end.

* LockedOutOfTheFight: In the third game, the 4 Guardians only show up to aid Zero after he defeats all three of the FinalBoss' forms.

* MothMenace: Robotic moths appear in Cubit Foxtar's level as enemies. They usually appear in darkened rooms, in which you can choose to turn on the light (by powering up the generator), causing them to move towards the light instead of swarming you.

** The Cyberspace areas in ''Zero 3'' are also inaccessible [[spoiler:except for in Sub Arcadia, due to the BonusBoss hidden in it]], which means no Satellite Elf usage whatsoever.

--->'''Ciel:''' With [[spoiler:both Weil and]] Craft gone, who could still be [[spoiler:running Ragnarok]]? Zero, [[StarWars I have a bad feeling about this]]. Just be careful, okay?

** Omega [[spoiler:Zero's]] finisher is a seven hit combo that he initiates by dashing low to the ground at Zero, ressembling Akuma's [[Franchise/StreetFighter Shungokusatsu]]. It is actually called ''Rambu'', though, meaning "berserk dance."
