Mega Man X

Mega Man X (ロックマンX) is a series of action platform games released by Capcom. It is a sub-series of the Mega Man franchise previously developed by the same group with Keiji Inafune acting as one of the main staff members. The first game was released on December 17, 1993 in Japan on the Super Famicom and the following month on the Super NES in North America. Most of the sequels were ported to Microsoft Windows. The gameplay introduces new elements to the Mega Man franchise in the form of Mega Man's successor X including his new skills and power-ups in the form of armors while retaining the ability to decide which boss to fight first.

Set 100 years after the original games, the story follows X, the last creation of Dr. Light whose free-willed programming and intelligence allows for countless other free-willed androids called reploids to be produced. When these reploids begin to go "Maverick" and start to rebel against the humans under the command of Sigma, X decides to make up for his creations by joining the Hunters. Throughout the series, he is partnered by his superior Zero, who becomes a playable character from Mega Man X3 onwards. A third character named Axl, joins the group from Mega Man X7 onwards. For the remake Mega Man Maverick Hunter X, the antagonist Vile debuted as a playable character. While at first Zero possess the same skills as X, he becomes a swordsman in Mega Man X4.

The video games have also inspired several spin-offs that deal with other villains while several manga adaptations have been produced. Critical reception to the Mega Man X series was generally positive for its faster-paced action in comparison to the original series, but the continuous release of installments led to criticism about Mega Man X lacking innovations. A sequel series titled Mega Man Zero followed, and focused on its titular character while several crossovers involving X and other characters from the series have been produced.

Plot
The plot focuses on "X", a mechanical being created by Dr. Thomas Light. He is a new type of robot with the ability to think, feel, and make his own decisions. Recognizing the potential danger of this model, Light sealed X away in a diagnostic capsule for over 30 years of testing. X's capsule is uncovered by an archaeologist named Dr. Cain almost 100 years after X's creation. Excited by the possibilities X presented, Cain disregarded the warnings Light had logged in the capsule and created a legion of robots that replicated X's free will; these robots were called "Reploids" ("Repliroids" (レプリロイド) in Japan).

A number of Reploids turned against humans led by the rebellious Reploid Sigma. These Reploids are dubbed "Mavericks" ("Irregulars" (イレギュラー) in Japan), and a force called the Maverick Hunters ("Irregular Hunters" (イレギュラーハンター)) was formed to combat them. The Maverick Hunters were led by Sigma until he, too, became a Maverick and declared war against the humans, thus starting the Maverick War. X takes it upon himself to join the Maverick Hunters under his superior Zero. Throughout the series, X and Zero battle against the Mavericks to stop their plots to destroy the human race. Sigma continues using his power and a virus to create more conflicts with the Maverick Hunters and attempt to destroy the planet in the process. While X and Zero also gain new allies, in Mega Man X7 they work with the missing Maverick, Axl, who becomes their partner. In the latest game, Mega Man X8, it is revealed New Generation Reploids are doomed to become Sigma copies with the original Sigma dying in the process in his final showdown with the Hunters.

After the series reached an unresolved cliffhanger, a game entitled Mega Man X Dive was released by Capcom Taiwan in which a human plays Mega Man X, until due in part to some corrupted data known as Maverick Data, he/she gets transported into the Deep Log, a massive database with data on every Mega Man game. The player must progress through the scrambled code of the Maverick Wars, Elf Wars, and the Game Of Destiny, to destroy the Maverick Data causing the slow corruption of the Deep Log. In contrast to the Mega Man Zero and ZX sequel series, the spin-off Mega Man X: Command Mission instead is set in a future where X is a veteran Maverick Hunter dealing with rebellions. Capcom expressed their desire to portray X and Zero as stronger versions in this spin-off of their previous incarnations even if they come across as out-of-character to the audience.

Rockman X Interactive (1995–1996)
An interactive movie game known as Rockman X Interactive was in development between December 1995 and 1996; it would have featured several new characters and reportedly greatly influenced the direction of Super Adventure Rockman, another interactive movie which released in 1998. A copy of the design documents were once being sold on Yahoo! Auctions Japan, but were later taken down due to concerns about how the seller obtained them.

Maverick Hunter (2010)
In 2010, Armature Studio, a development studio founded by the creators of Metroid Prime, were developing a first-person shooter trilogy titled Maverick Hunter, which was intended to build on the mythology of Mega Man X. However, it was cancelled by Capcom after six months of development due to it being considered a "significant gamble" for the company. The game was one of the several cancelled Mega Man games of the 2010s, which also included Legends 3, Online, Universe and Star Force 4. 

Rockman XZ: Time Rift (2020–2021)
Rockman XZ: Time Rift was first revealed in September 2020 on NebulaJoy's official website, which included the game's logo. It was a crossover game between the X and Zero series for mobile phones, in a similar vein to X DiVE. Shortly after footage of the game leaked online, it was announced that the title was cancelled in August due to the underperformance of Devil May Cry: Pillar of Combat.

Gameplay
The original Mega Man series on the NES consisted of 2D platform games that focus on run-and-gun gameplay. Mega Man X uses the same basic principles as its precursors but with many added options. X has, by default beginning with X2, the ability to dash along the ground, cling to walls, jump off walls, and dash jump to cover greater distance than a normal jump. This all gives X more mobility than his original series counterpart. At certain times, the player can pilot vehicles including in an attack mech and an attack hovercycle.

X is also able to locate capsules and tanks that permanently upgrade his armor. These upgrades are all either hidden or require an exceptional feat to reach. Upgrades common to each game are increased maximum hit points, "sub-tanks" which can be filled with surplus health pick-ups and then used at any time to refill the character's hit points, and the ability to charge weapons earned from bosses, which gives them an enhanced secondary fire mode. In later games, there are multiple armor types available that can either be mixed and matched, or completed for additional armor set bonuses.

Mega Man X3 is the first game in the series which allows the player to play as X's ally Zero, although his playability is more limited compared to later games in the series. He relies on his saber almost exclusively starting in X4. Zero is more melee-oriented than X by using a "Z-Saber" sword. Rather than acquiring weapons from the bosses (with the exception of his Giga Attack), Zero learns special techniques that do not require ammo such as the "Hienkyaku" air-dash and "Kuuenbu" double-jump. However, Zero cannot upgrade any of his body parts in this game. In X6 and X7, the player can rescue Reploids to replenish health and acquire upgrades not otherwise available. In X7, the playable character Axl is introduced. Axl utilizes two guns known as Axl Bullets. In X8, a tag system is introduced, along with a new Double Attack feature, where the two selected characters can attack at the same time.

Mavericks serve like a boss. The stage boss Mavericks are based on various types of organisms (usually animals, but plants and fungi are also represented) instead of being humanoid, as were most of the bosses in the classic series, although their attacks and names are usually based on mechanical or chemical phenomena or laws of physics like in the original games. Defeating a Maverick allows X to use that Maverick's signature weapon. Each boss is particularly weak to one special weapon, so the player may complete the stages in an order that best exploits these weaknesses.

Production
Mega Man X was developed by a team at Capcom which had worked on the long-running Mega Man series for the NES. Lead artist Keiji Inafune (credited as a planner as Inemuryar) recounted that the development of Mega Man X required a lot of brainstorming for its storyline and content where the team's goal was to branch out from original Mega Man games while still maintaining their fundamentals. In the original Mega Man series, Inafune typically designed the protagonist while his protégé Hayato Kaji handled the supporting characters. However, their roles were reversed for Mega Man X. Inafune and Kaji worked simultaneously on the various designs for X with different pieces of armor attached. The idea for the armor parts came about because the game was planned during a time when role-playing video games were becoming extremely popular. Inafune felt that Mega Man had always represented a classic action game formula in which the hero earns his defeated enemies' abilities; the armor parts were added to supplement this concept.

The development team additionally wanted the world of Mega Man X to be much more sophisticated than in the first Mega Man series. They wanted to accomplish this with Zero's "hardcore" personality and the game's antagonist Sigma. As stated by Inafune, the original series' villain Dr. Wily had "a side to him you couldn't really hate". Sigma, however, was written as a once-good character suffering an "unforeseen error" that leads him to be completely evil. Starting with Mega Man X2, Inafune wanted to use a computer virus as a plot device, something he considered a more interesting idea than a tangible villain. This led to the creation of the Sigma Virus seen in Mega Man X3 onwards.

Originally, the Mega Man X3 team had no plans to provide a sequel until their superiors from Capcom aimed to try the X series on new hardware. The team aimed to make Zero different from X, he was remade as a proper samurai-like warrior who wields a Z-Saber instead of shooting like X. In order to get the approval to make Zero playable, the developers gave him special moves based on the Street Fighter fighting game series to compensate for lacking X's powers. In particular, Capcom struggled in the beginning with the number of backgrounds they had to draw, but were pleased with results. There were twice as many sprite animation patterns to create. Instead of presenting Repliforce as blatantly evil villains like Sigma, the writing staff decided to leave them some "moral leeway". They did not want the ideals of Repliforce and the Maverick Hunters to be so black-and-white.

Ever since the series started, Inafune wanted to add Dr. Wily to the story leading to the twist of Mega Man X4 that reveals he created Zero to set the climax of the series. Mega Man X5 was originally intended to be the final game in the Mega Man X series. According to Keiji Inafune, he had little to do with the title and told the staff his idea. Much to the dismay of Inafune, Capcom decided to publish Mega Man X6 the following year, in which Zero survived his fight from X5. Suetsugu believed that the navigator Alia might be the most fitting heroine in the series in contrast to the tragic Iris from Mega Man X4. Alia stood out as the only female character, which Suetsugu did not mind since the game is aimed towards a young demographic. As the idea of having a calm woman as navigator proved difficult to execute, the other navigator Roll Caskett from Mega Man Legends was used as a reference.

Kitabayashi explained that transitioning the character models of Mega Man X from 2D to 3D graphics was a challenge, but that including both 2D and 3D gameplay was not, as they had planned to have them in equal amounts for the game. The development team took into account the less-than-favorable reception for Mega Man X6, but instead of simply trying to make the next game new and fresh with 3D graphics, they decided to focus on "getting 3D right". The team also attempted to build upon the action-style gameplay for which the Mega Man franchise is known along with the more adult-themed storyline of the Mega Man X series. This involved adding the newer, non-traditional character Axl to deepen and better the narrative. Kitabayashi emphasized, "He's young, he's running away. He's like the new younger character of the group, and that's why I wanted to put him in there." However, the development team chose not to pursue 3D gameplay for Mega Man X8 simply because of its graphical style. The game's main illustrator, Tatsuya Yoshikawa, was an assistant in X7 and took a bigger role. He was responsible for designing the protagonists, the Maverick bosses, and the newer ancillary cast. Yoshikawa took into account what the characters may resemble if they were toys, and even imitated the joints of Revoltech figures. Similar to his previous work in X7, Yoshikawa wanted the designs to pander to his feelings about the first Mega Man X game while still following his own ideas too. The three main characters were revised for Mega Man X8 as Yoshikawa planned to give them more unique features to contrast their personalities.

Animation
In Maverick Hunter X, the player can unlock an OVA called The Day of Sigma that details the events leading up to the first level, including Sigma turning Maverick; it was produced by Xebec (who also produced MegaMan NT Warrior and Mega Man Star Force) and later included in the Legacy Collection. Characters from the X series also appeared in the Mega Man animated series in the episode "Mega X", which was a pitch at an X cartoon that never got off the ground.

Print media
Several tie-in manga adaptations have been released, mainly serialized in Kodansha's children's magazine Comic BomBom, its quarterly special issues and its sister magazine Deluxe BomBom. An adaptation of the first four games in the series by Yoshihiro Iwamoto ran from 1994 to 1998 and was collected into 12 volumes. An original story featuring elements from the first Mega Man X game called Irregular Hunter Rockman X by Shigeto Ikehara ran from 1994 to 1995 and was collected into two volumes. The magazine also published several one-shots, including one based on the Mega Mission carddass series by Hitoshi Ariga and an original self-contained story called Team X Shutsujin seyo!! by Daisuke Inoue. Yoshihiro wrote an alternative ending to Mega Man X5 in 2018.

The character of X appeared in the obscure Brazilian comic Novas Aventuras de Mega Man (translated as The New Adventures of Mega Man), where he is Classic Mega Man and Roll's younger brother; the comic rather notoriously implies that all three characters are attracted to each other in a sexual manner. Similarly, the fourth and final issue of the Dreamwave Productions comic series included a short story with Mega Man X at the end of the issue, where X travels back in time to get help from Classic Mega Man and Dr. Light; the intention was to publish a comic based on Mega Man X, however Dreamwave shut down before any issues were released.

Characters from Mega Man X appeared twice in the Archie Comics series; the first time was during the Dawn of X arc, and the second time was during the Sonic the Hedgehog crossover Sonic and Mega Man 2: Worlds Unite. Writers noted that prior to his introduction, many fans sent them messages expressing a desire to see X portrayed as a darker character. They decided not to start with the Command Mission incarnation, which depicted X as more of a leader.

Crossovers
X and Zero have appeared in other video games. In Dead Rising, the protagonist, a photographer named Frank West can unlock and wear an X outfit. Zero also appears as a hidden character in Tatsunoko vs. Capcom: Ultimate All-Stars and as a playable character in Marvel vs. Capcom 3: Fate of Two Worlds, Ultimate Marvel vs. Capcom 3, Marvel vs. Capcom: Infinite, and Teppen. For Marvel vs. Capcom: Infinite, X was included due to his significant popularity with Western audiences alongside Zero. They also appeared in the two role-playing games Project X Zone and Project X Zone 2.

Reception
Several websites retrospectively held Mega Man X as a successful milestone in transitioning the Mega Man series from its increasingly stale existence on the NES to the SNES. IGN named it the twelfth-best on its own top 100 SNES games list in 2011. The sequel Mega Man X2 was often praised for providing the player with new content GameSpot editors Christian Nutt and Justin Speer were appreciative of Capcom's attempt at expanding Mega Man X2 over its predecessor in all aspects. By the release of Mega Man X4, critics praised the added option to play through the game as either X or Zero, noting that the drastic differences in the way the characters played the same levels added to the game's replay value. The English voice acting was still criticized for poor performances. Mega Man X5 was generally well-received as an appealing sidescroller, although several sites commented that it did not contribute new major ideas to the franchise. The next two games were been critcized for a harsh difficulty caused by poor design, as well as recycled narrative. With the transition to 3D graphics, the general consensus was that the game's mixture of 2D and 3D gameplay was well-intentioned but poorly executed. The latest game, Mega Man X8, was generally praised for returning to a more classic style of Mega Man gameplay and removing the criticized gameplay elements of Mega Man X7, making it a much more appealing game than its previous two predecessors.

Mega Man X was a commercial success. The SNES version sold 1.165 million copies worldwide ,

IGN's Jeremy Dunham speculated that the game's more mature storyline and its inclusion of numerous gameplay extensions over the original Mega Man series helped create a "unique cadre of fans". The story is notable for being more violent than the predecessors with stages and bosses also looking scarier  Capcom producer Kazuhiro Tsuchiya played the first Mega Man X in his youth, enjoying the successor to the first Mega Man character, X, due to he having new unique skills, helping to popularize the "golden age of action games". X's characterization was often praised for coming across as a unique tragic hero similar to Hayao Miyazaki's works as well as dystopian works in general, compared to Ghost in the Shell, Casshan, as well as other famous gaming icons like 2B from Nier Automata, and Raiden from Metal Gear, who question the nature of his missions. Alexander expressed feeling guilty upon completing the game as the final narration highlighted X's depression over the chaos of war. His popularity led to criticism in Mega Man X7 for being the first and only time to have him unlockable and the player having to use his replacement Axl instead.

Meanwhile, Zero stood out mainly in his debut as playable character due to having own iconic techniques. Additionally, Brett Elston from GamesRadar credited Zero as one of the reasons the X series became so popular and that his own popularity within gamers earned him his own video game series. When compared with Zero, X was often seen as the less compelling character, with Zero being the more memorable of the two. The villain Sigma Sigma was praised for his backstory, resulting in the story of Mega Man X having unclear morality. Patrick Lee of The A.V. Club, however, stated that Sigma is "exactly the sort of boogeyman anti-progress allegories are built around". Saying that he is the "first piece of technology the Mega Man series suggests was a mistake to create", he says that Sigma runs contrary to the previous, optimistic themes of the series, which suggest that technology is ultimately beneficial to mankind, and that robots are "morally neutral tools". He described this "more cynical worldview" as "anti-technology scaremongering."
