Cyberworld

The Cyberworld (サイバーワールド), or Cyberspace (サイバー空間), is an alternate dimension featured in the Mega Man series. As its name implies, it is a digital world created through the advanced technology of the series.

Characteristics
The characteristics for the Cyberworld vary to almost nothing for both series, but rather their difference is based in the relevance it has for each series. The Cyberworld is a digital space created via Computers whose main purpose is to ease the life of people as well as for researching in laboratories, similar to the real-life Cyberspaces, however considering the timeline of the series it is to know that the Cyberworld is to be considered far more advanced and reliable, although not 100% safe, as it can also be attacked by bugs and viruses as any source of data. The Major difference between the Cyberworld of the series and that of the real world is the ability to be able to literally travel to the Cyberworld, in other words to be able to be digitalized and become Data to be in the Cyberworld itself. However this trait is mainly used when a network is attacked by dangerous viruses and/or bugs, thus digitalizing the most capable fighters to get rid of them as being deleted in the Cyberworld is by all means dangerous and can be fatal, thus hinting that only capable fighters are granted all their abilities as they are digitalized. It is also possible for data to be materialized in the real world, but this requires incredible power and intellect.

Mega Man X series
The Cyberworld does not really appear in the main series until later in the X series. The Cyberworld appears as mission stages when Maverick viruses (argueably digitalized Maverick Reploids) attack facilities' network and as such the player must be digitalized to destroy the threat. In the X series the Cyberspace is featured when Techno hijacks data about the Maverick Reploids thus being reborn, featuring as well that data can be materialized from the Cyberspace into the real world. The Sigma Virus itself being an example of such, being able to be seen and attack, as well as materializing Mechaniloids, however materializing data requires extraordinary power, and as such it is not a capacity totally exploited in the series. Magna Centipede's stage is a Computer Center where everything is run by its network, such as the security system and the sensor system which appears in an incredibly large room in which boulders fall and the player must avoid to be locked-on otherwise it will give power to the sub-boss Radar Killer.

The later trait of the Cyberspace is in Mega Man X4, where the player must face Cyber Peacock and the stage itself is an area of the Cyberspace, in which the player is given a limited amount of time to avoid bugs and digitalized Mechaniloids in order to reach to a warp point, shall the player score an S rank it will have access to a hidden area with prizes. Manipulation of time and space is seen in this world as the player can press a button to literally put the world perspective in reverse (what was considered floor now is the ceiling and vice-versa).

A major trait of the ability to materialize data into the real world is seen in the Mega Man X6 series, in which Gate is able to create and materialize the Nightmare Virus which antagonises most of the game, as well as the feature to alter the real world as it is often in stages how the Nightmare Virus can create bizarre phenomena such as raining fire balls, materialization of metal cubes, determinated areas-freezing, attraction of fly Mechaniloids, almost complete darkening, materialization of ground masses, etc.

In Mega Man X7, a Cyber Field is the stage for the mission of Snipe Anteator, the stage features unbreakable barriers (possibly some sort of Fire Wall) only bypassed by Axl's copy ability of samurai Mechaniloids (possibly meaning that the "Fire Walls" only allow "recognizable" data, while rejecting others, the other copy-able Mechaniloids possibly serving as bugs) the user can also alter the gravity by jumping in specified platforms in which the player can literally play head-down.

Mega Man Zero series
The Cyberspace appears as of Mega Man Zero 3 in which the player can access to the Cyberspace in almost every stage of the game, thus featuring that the Cyberspace is present in every place of the world not necessarily where computers are run, however as of the Mega Man Zero series science is far more advanced than that of the X series, possibly hinting any post-X era repercusions of the Cyberspace into the real world after the former has had real impact in the latter. When one travels into the Cyberspace the screen turns green-like and the player can move with more ease, thus serving as a shortcut, however each Cyberspace is limited and basically no stage can be finished in the Cyberspace. In Mega Man Zero 3, shall the player be in the Cyberspace area of the stage Sub Arcadia, it can unlock a special room in which the destroyed Hidden Phantom can be faced once more.

As of Mega Man Zero 4, the Cyberspace plays a little role in one of the stages in which Zero must travel into Ragnarok's network to destroy the security systems thus allowing him to be able to assault the core. The boss of the stage is the security system itself, Cyball.

A major trait of the Cyberspace materialization into the real world is shown by the Cyber-elves, AI creatures which are able to materialize in the real world and each one having special powers the player can use.

MegaMan Battle Network series
The Cyberworld in the MegaMan Battle Network series is the basis for the day-to-day life as the whole society is run by computers, thus being extremely important for every system in the world to be able to function properly. NetNavis are the "data people" of the Cyberworld serving as AI programs which emotions and their own intelligence however most of them serving humans preferring co-operation (similar to how Reploids are in the main series). The network though very stable is never fully rid of viruses, thus NetNavis are each in some point made for combat of viruses though this applies for "weak" viruses. Battle Chips contain programs that both a Navi and virus can use alike to materialize (in the Cyberworld) blades, guns, flamethrowers or any kind of weapon and phenomena alike. Differently from the main game's Cyberworld in this one there are two kinds of deletion. The one is the basically fatal-like deletion in which any deleted Navi or virus is to fully cease to exist and the other deletion is the deletion through "friendly combat" in which NetNavis fight each other as some sort of sport, in this case deletion never causes a Navi to be destroyed but rather be exhausted and unable to fight until being restored.

The Cyberworld is featured in every game as the main plot of the games involve the players getting themselves in the "need" to check the source of problems when a virus, bug, Hijacks an specified network thus wreaking havoc (normally being lead by a Navi operated by a hacker or any kind of Cyber criminal). In this Cyberworld bugs are almost never shown as enemies but rather as energy/money sources the player can use for more powerful accessories.

It is to know that the ability to materialize data into the real world is shown only in the last game in which a Navi can use a Copybot and appear in the real world. However in the anime this characteristic is far more exploited when Nebula uses Dimensional Areas to materialize their Darkloids, as well as Duo's Asteroid Navis and cache's phantoms requiring no Dimensional Area.

MegaMan Star Force series
The Cyberworld is replaced by the EM (electromagnetic) world. The ability to materialize into the real world is never shown at all, but it is rather that people can "see the EM waves" than a EM-being being in the real world itself. The EM world has almost no differences with the Battle Network series Cyberworld, and having the same functions and importance.
