History VideoGame / MegaManZero4

Followed by ''Videogame/MegaManZX''.

Though Zero destroyed Omega and thwarted Project Elpizo in the prior game, Dr. Weil still rules over Neo Arcadia with an iron fist and has begun persecuting both humans and Reploids. This forces Neo Arcadians to flee their homes to establish a new colony in the wilderness, settling in [[NewEden Area Zero]] (the crash site of the Eurasia colony from ''VideoGame/MegaManX5''). Zero learns of Operation Ragnarok, a military campaign by Weil to obliterate all inhabitable places like Area Zero so that humans cannot flee Neo Arcadia, and decides to thwart Weil's evil plans.

* GetBackHereBoss: Almost half of the eight bosses use a disappearing trick of some sort as part of their strategy, leaving very little opening for Zero to attack. This can be worked around with two of them (Mandrago and Kraken) who are vulnerable to the Z-Knuckle in this state.

The game introduces the Zero Knuckle, a weapon that lets Zero steal other enemies' weapons and use them for himself, as well as a new mechanic where Zero can alter weather conditions before entering one of the eight main levels, which modifies the level layout, enemy placement, and whether the boss can use their EX skill for Zero to [[PowerCopying copy]].

Dr. Weil still rules over Neo Arcadia with an iron fist. This forces Neo Arcadians to flee their homes and try to establish a new colony in the wastelands, finding NewEden Area Zero (the crash site of the Eurasia colony from ''VideoGame/MegaManX5''). Zero learns of Operation Ragnarok, a military campaign where Weil plans to obliterate all inhabitable places like Area Zero so that humans would stop running away from Neo Arcadia, and decides to thwart Weil's evil plans.

''Mega Man Zero 4'' is a video game created by Creator/{{Capcom}} and Creator/IntiCreates for the UsefulNotes/GameBoyAdvance in 2005. It's the fourth and final installment in the ''VideoGame/MegaManZero'' series.

The game introduces the Zero Knuckle, a weapon that lets Zero steal other enemies' weapons and use them for himself, as well as a new mechanic where Zero can alter weather conditions before entering one of the eight main levels.

** Carnage Force-0 and Hell the Giant are reworked versions of the Introductory Level bosses from ''VideoGame/MegaManX2'' and ''[[VideoGame/MegaManX3 X3]]''. The in-game database even mentions that Carnage Force is built from ancient blueprints.

* DamnYouMuscleMemory: The hanging ledge ability from ''X5'' to ''X6'' returns here. Unlike those games, where movement like dashing is possible, Zero remains stationary (unless the "ledge" itself was moving) and must jump to move around.
* ADayInTheLimelight: This is the first game in the ''Zero'' series (and really, in ''any'' game of the original timeline) that actually gives humans the spotlight to see what their side of all the {{Robot War}}s is. The result is, as expected, [[HumansAreFlawed decidedly mixed]]: Humans are shown to be [[FantasticRacism quite distrustful and even hateful of Reploids]], blaming them for constantly starting wars that have ultimately ravaged the planet and made life for everyone difficult. It's the reason why they've refused to let Reploids into their settlement in Area Zero and distrust the Resistance despite being helped by them. [[JerkassHasAPoint There is a bit of a point to that]], but they are also woefully misinformed on many things, such as ignoring how the current Robot War was sparked because the Neo Arcadian regime prioritized human safety and comfort over Reploids to the point of being willing to genocide the latter on flimsy excuses, that their "hero" X was actually a delusional and woefully inept KnightTemplar copy who started it all, and the fact that humans actually had it very well off in the current CrapsackWorld as a result until [[TyrantTakesTheHelm Dr. Weil]] (a ''human'' himself) decided to make life a hellhole for ''everyone''. Zero observes this and isn't very impressed with them as a result, several times calling them out on being such stuck-up, cowardly and ungrateful bastards. At the same time, the humans ''are'' capable of seeing past their prejudices and ultimately come to realize how wrong their viewpoint really is.

* GrandFinale: ''4'' marks the conclusion of the ''VideoGame/MegaManZero'' subseries[[note]]though the story continues on to the distant future with the ''VideoGame/MegaManZX'' series[[/note]] (and the first to do so in the entire ''Franchise/MegaMan'' franchise), seeing Zero put a stop to Weil and his tyranny over Neo Arcadia. [[spoiler:He succeeds, but not without going down together with Ragnarok.]]
* GreenAesop: Plot here is protecting the last trace of nature from a villain bent on making sure that his [[TheEmpire empire]] is the only habitable place left on Earth.

** There is no incentive to maintaining high rankings aside from bragging rights[[note]]something that even the first game does have[[/note]], since the eight Bosses now use their EX Skills if the weather is favorable to them.

** Zero, Ciel and a select few members operate from a mobile unit instead of the Resistance Base. The rest of their forces do not appear, even in any of the missions, save for [[spoiler: the rescue of survivors from the ruins of Neo Arcadia]] and the ending.

* NeverFoundTheBody: [[spoiler:All that remains of Zero after defeating Dr. Weil and destroying Ragnarok is his shattered helmet, stranded in somewhere in the desert. Ciel, however, remains hopeful that Zero is still alive.]]

* PowerStereotypeFlip: Despite being a lightning user, Mino Magnus is slow both in thought, speech and movement.

* TheEndOfTheWorldAsWeKnowIt: DoubleSubversion: the ColonyDrop really isn't going to bring out the aforementioned effect; however, seeing as the target of the drop is a NewEden area in a CrapsackWorld where all other forms of nature are mechanical reproductions, it arguably comes close.

* DiscOneFinalBoss: Craft the new [[DragonInChief commander]] of the Neo Arcadian army. At the climax of the game he turns against (and destroys) Neo Arcadia, supposedly killing Dr. Weil, and Zero storms Ragnarok to fight him. The heroes thought that defeating Craft will finally be the end of it, until Ragnarok starts moving again, and it's revealed in the end that Weil survived Craft's attack.

* SenselessSacrifice: After being inspired by a speech on how it is better to [[GiveMeLibertyOrGiveMeDeath laugh at death than to live without freedom]], Craft, betrays Weil and uses his laser satelite to destroy their capital, dying at the hands of Zero for his efforts. [[spoiler: Now the heroes need to stop the satelite from continue firing. But turns out Weil can't die and is the only with complete control of the satelite, making Craft's betrayal and subsequent death pointless.]]

** Later, [[spoiler:Craft pulls out a HeelFaceTurn (sort of) and tries to destroy Neo Arcadia and Weil using [[KillSat Ragnarok]]. You are sent to stop him, but right before the final boss door, the Ragnarok is successfully fired, claiming millions of lives. And then you fight him]].

** Using the Zero Knuckle to remove the vines in Noble Mandrago's stage is much faster than trying to slash or shoot them, and can save precious time when clearing a level.

** A UniqueEnemy is the Card Key-holding

** All eight of Weil's numbers from ''VideoGame/MegaManZero3'' make brief appearances as projections for one of [[spoiler:Dr. Weil's]] attacks.

* DamnYouMuscleMemory: The hanging ledge ability from ''X5'' to ''X6'' returns here. Unlike those games, where dashing while hanging is possible, Zero remains stationary (unless the "ledge" itself was moving) and must jump to move around.

* HelpfulMook: A variant with the helicopter enemies. They provide aid via their propellers; when the main body is destroyed Zero can use the propeller to fly upward. One use for this is to reach the Sub Tank in Noble Mandrago's level.
