Mega Man X5

Mega Man X5, known as Rockman X5 (ロックマンＸ５) in Japan, is the fifth game in the Mega Man X series and the third X game on the PlayStation console. It's also the only game to have a time limit on the stage select. The FMV sequences, seen in Mega Man X3 and Mega Man X4 (with the exception of the game's opening), have been replaced with still screens and text.

The player can choose X or Zero in the title screen, but you can still choose between the two characters later inside the game (a staple of the series starting with this game). The only difference is that if the player chose X, he will be able to use the Force Armor, and with Zero, he will be able to use the Z-Buster.

It should be noted that series creator Keiji Inafune originally intended for this to be the last title in the Mega Man X series, with Zero dying and resurrecting later in the Mega Man Zero series, but Capcom later decided to green-light Mega Man X6 against his wishes, changing his plans.

Story
Several months after the Repliforce war, Earth is at a peaceful time. The repair of the space colonies damaged during the war was almost complete, the only space colony remaining being the giant colony Eurasia located in a Lagrangian point. As it was quite old, it was planned to receive extensive renovation. However, one day someone had occupied Eurasia and took control of it, scattering a virus in the colony and using its artificial gravity systems to set it on a collision course towards Earth. Within 16 hours, Eurasia will crash and cause great destruction, in the worst case extinguishing all life from the planet. The Maverick Hunters plan on using the large particle cannon Enigma to destroy Eurasia before it happens. The Enigma cannon is somewhat old and needs to be upgraded. Signas, the Hunter's new commander, orders to Mega Man X and his comrade Zero, as they race against time to collect the four parts necessary to upgrade the Enigma and stop Eurasia before it's too late. To make things worse, Sigma scattered the Sigma Virus all over the world and the parts needed are being protected by Mavericks.

From this point, the story diverges into different subplots:
 * Once X and Zero have recovered the initial four items required to use the Enigma, it is fired and can either succeed in destroying the space colony or fail and only destroy part of it.
 * If the Enigma fails, only part of Eurasia is destroyed, slightly changing its orbit and delaying the crash. Signas begins his next plan: launching a space shuttle (which is infected by the virus and the auto-pilot doesn't work) directly at the colony to destroy it. Again, four pieces must be collected to enhance it from the last four Mavericks, and after doin so the shuttle will launch with Zero as its pilot (as Zero mentions, he is the only competent pilot left).
 * Like the Enigma, the space shuttle can either succeed or fail.
 * If the shuttle succeeds, 86% of Eurasia is destroyed and Earth is no longer in danger. Zero contacts the Hunters from his escape pod to tell them he's okay and that he'll land soon. After Zero lands, the Hunters come to pick him up. Mega Man X6 shows that this is the scenario that happened. However, the remains still caused large damage to Earth's surface, devastating its ecosystems and spreading pollution around the planet.
 * If the shuttle fails, only part of Eurasia is destroyed and it crashes on Earth. Zero becomes a Maverick.
 * If time runs out, Eurasia collides on Earth, and Earth barely survives. Zero becomes a Maverick.

In any scenario, Eurasia (either complete or only its remains) fall into Earth and the colony virus merges with the Sigma Virus, creating a new virus in the local of the collision in the point 11F5646. Alia detected the strange energy of the virus and dubbed it the Zero Virus due to its similarities with Zero. The Hunters go into Eurasia's remains to verify the virus. If Zero became a Maverick, X still feels as if he can save Zero, so X fights through the area to get to Zero and help him.

Upon entering the third Zero Space stage, X and Zero confront each other, the dialogue changing depending of the character currently used:
 * If the player is using X, he will confront Zero about the latter's rise in power, and plead with Zero to go back to the Hunter Base to get a check-up, which Zero stubbornly denies.
 * If the player is Zero, he will confront X and two Lifesavers (the Hunters' medical unit) and will be labelled as a Maverick by the Lifesavers due to Zero's immunity to the Sigma Virus.
 * If Zero "awakened" with the virus, X confronts the "true" Zero, whose power had grown tremendously. X narrowly defeats Zero.

Either way, both X and Zero fight in a room where Dr. Wily's mark is displayed prominently in the background, and just as the fight is ending, the opponent uses Soul Body on the player to weaken him. They lie exhausted on the ground. Sigma appears out of nowhere intending to finish X off. Zero jumps in front of X's prone body and protects him from Sigma, claiming to know everything Sigma is trying to do. Sigma concedes defeat and vanishes for the moment, saying he will be waiting. The Hunters then prepare to the final battle against Sigma.
 * If Zero is normal, he attacks Sigma with his Z-Buster, and collapses with the exhaustion.
 * If Zero became a Maverick, he returns to normal and sacrifices him life to save X.

Once in the final chamber, Sigma reveals that his entire plan hinged on awakening Zero from his "false self" and giving him his true power by infecting him with a massive amount of the Sigma Virus, scattering it around the Earth. But as the amount was not enough to awaken him, he used the colony as a virus and let it land on the Earth. The Hunters fight Sigma, who loses and reveals his final body; a huge, unfinished battle body. Sigma tells X of an old man he met, with a seemingly undying hatred for X. If the player is Zero, Sigma tells him of the same man, who supposedly knows enough about Zero to be his own father (at this point, it is obvious that Sigma is referencing Dr. Wily). X and Zero fight Sigma's last body and defeat him, but Sigma has one last trick up his sleeve; he self-destructs, attempting to take both of them with him.

After the explosion, the extent of the damage is shown; Zero's body lies shattered on the ground, his lower torso and left arm apparently destroyed in the blast. X kneels down to pick up Zero's broken body and pleads with him not to die, not noticing Sigma's severed head charging a blast behind him. Sigma fires an energy blast at X, catching both he and Zero in the chest and creating a hole there. This blast seemingly jars Zero from death, as he smiles and blasts Sigma's head with his Z-Buster, finishing him for good. He lies on the ground and calls for X, noting that his friend's optimism at the thought of Zero living is what lead to his death.

In Zero's ending, he reflects on his life as a vision of him in his original body fighting the original Sigma (a fight referenced in a flashback in Mega Man X4) comes up. He assumes these visions are due to his power source running out and his memory unit malfunctioning as another vision, this time of a blurred Dr. Wily come into view. The focus shifts from the doctor to an incomplete Zero lying on a table, where Zero notes he was created for destruction. A red and faded picture of Iris then flashes through his mind, while Zero apologizes to her. He then makes a remark that it would be better for him to die, so as to restore the peace. Zero then tells X goodbye, and passes away.

In X's ending, he is missing his lower torso and both arms after Sigma's explosion. A mysterious glowing figure (obviously being Dr. Light) appears and tells X to rest and relax. X than is repaired and returns to the Maverick Hunters. His ending has two varieties:
 * If Zero was normal, a scene three years after the final battle with Sigma is shown. Alia alerts the Maverick Hunters of a large Maverick rampaging in HORIE 2146 block, and X tells the three new Hunters nearby to move out. The final scene shows X holding Zero's Z-Saber, while one of the other Hunters remarks that X's eyes have changed and sharpened, more and more reflecting his former partner and friend, Zero. X then says that as long as he has Zero's saber, he can fight any enemy. This ending leads to Mega Man X6, which happens three weeks later instead of three years.
 * If Zero became a Maverick, the glowing hologram tells X to hold on for just a little longer, and to forget all of his painful memories. The scene fades. One week later, X and two other Maverick Hunters are moving some things. One of the Hunters asks X if he remembers anything about what had happened the previous week, with X firmly stating that he doesn't remember anything about the battle. The other Hunter remarks that X is now a Special-A rank Hunter, the same as Zero, and explains to X that he and Zero worked together to defeat Sigma. X comments that he didn't forget Sigma's name; he remembers it clearly, and yet he has no memory of Zero. He assumes that whoever repaired him may have accidentally deleted the data (Dr. Light erased X's memories to ease the pain of fighting Zero and leading to his death). One of the Hunters says that it's a miracle X came out of the battle at all. The scene then shifts to the control center, with Signas, Alia and Douglas. Signas remarks that it's indeed a miracle X came back, and without so much as a scratch. Douglas mentions that it's still difficult to repair X and Zero's bodies, since their internal workings are still a mystery. Alia says that she's not interested in miracles, and doubts most Reploids believe in them either. Douglas asks about X's memories of Zero, and Signas admits that even he doesn't know how it happened, be it an accident and purposeful. Alia mentions that there's a protection in X's systems now; X's body won't even accept data related to Zero, and even she couldn't program a protection that complicated. The final scene shifts back to X and the two Maverick Hunters, where X says that they need to work harder to achieve peace, and that his secret dream is to build a Elysium, a paradise for both humans and Reploids.

Trivia

 * Regardless of the gameplay progress (whether the player stops Eurasia or not) or selecting a character for the mission, the battle in the third stage of Sigma's fortress will always be between X and Zero.
 * When fighting X in the third Sigma fortress stage, he uses some of his Special Weapons from X4: an enhanced version of the Soul Body (where he launches many images at a time) and charged versions of Frost Tower and Double Cyclone.
 * In the same battle, X also dons his Ultimate Armor, making the battle the first (and so far, only) canonical appearance of the secret armor.
 * This is one of only two games, the other being X8, in which Sigma is not only fought once; he is fought as the intro stage boss as well.
 * All of the eight Mavericks' English names are based in the name of a member from the rock band Guns N' Roses.
 * Though indirectly, Mega Man X5 is referenced in Mega Man Zero 4, as the game's main setting, Area Zero, is revealed to be where the Eurasia colony crashed. By that time, centuries after X5, nature had returned to Area Zero. That certain aspect also forms part of Doctor Weil's plot.
 * The first Sigma fortress stage is a remake of Quick Man's level in Mega Man 2 and the second stage is a remake of the first Sigma Fortress stage from Mega Man X.
 * Many music tracks were re-used from previous games:
 * Duff McWhalen's stage music is a remix of Bubble Crab's stage in Mega Man X2.
 * The last part of the final boss music is somewhat similar to the song The Final Countdown by Europe. For that matter, Infinity Mijinion's stage music from Mega Man X6 also bears a thematic similarity to The Final Countdown.
 * The boss music from fighting Shadow Devil is a remix of Mega Man 1's Wily Boss.
 * The boss music from fighting Rangda Bangda W is a remix of the music used when fighting the same boss in Mega Man X (also the theme is used on a few of X1's other villains, including Vile).
 * The intro music is a remix of Zero's theme from Mega Man X and the Get Weapon theme from Mega Man 3.
 * Gamma Sigma is the second largest final boss after Dr. Weil fused with Ragnarok, and the largest of Sigma's forms.
 * Unlike X, Zero can air dash from the beginning of the game. It is possibly that he still had the Hienkyaku from Jet Stingray in Mega Man X4.
 * Also, when Zero is using the Zero Armor, his Z-Saber is purple, this could possibly be the Tenkuuha from Storm Owl.
 * This is the first Mega Man X game where there is a training mode, possibly because of the new abilities to duck and hold on to ropes.
 * Like in Mega Man X4, the game has a minor glitch that can cause it to crash on the Warning Signal at the beginning of boss battles on the PlayStation version, forcing the player to reset the game.
 * This was essentially planned to be the last Maga Man X game in the series. This is unofficially confirmed as to how the endings seem very dramatic and the fact that it is the only game in the series that X and Zero battle each other on a serious note. If the player picks Zero and fights X, X will wear the Ultimate Armor, the only appearance of it actually story-related.
 * Mega Man X5 is the last X game where you can go underwater.
 * It's also the first game where you can't shoot through walls.
