Mega Man X (Marvel vs. Capcom series)

"As long as there's hope, we can change the future."

- Mega Man X

Mega Man X is a character from the Marvel vs. Capcom series that made his first playable appearance in Marvel vs. Capcom: Infinite. Though he made his technical debut in Ultimate Marvel vs. Capcom 3, but only as downloadable costumes for Zero and Frank West and as a card in the Heroes and Heralds Mode. Though Zero's moveset and voice did not change, X did share some of Zero's abilities and weapons during a few points throughout the Mega Man X series, namely his Z-Saber.

Ultimate Marvel vs. Capcom 3
Mega Man X made an appearance as a collectible ability card in the free DLC mode, Heroes and Heralds. The card's primary ability is to grant players a fixed amount of Hyper Combo Gauge when knocking out an opponent (possibly based on his growth ability) and its secondary effect grants players an air dash. Zero also briefly alludes to X in one of his win quotes, snidely comparing Hawkeye to X both in cunning and in the fact that they lost to Zero.

X was later confirmed to appear as a downloadable costume for Zero (though Zero's moves and animations all still apply) and was released on February 7, 2012. Frank West also has his "Mega Man X" costume from the Dead Rising series as a DLC costume.

Marvel vs. Capcom: Infinite
X appears in the story mode, which starts in Xgard, a fusion of Abel City and Asgard. While most members of X's team are fulfilling their mission to retrieve a special person who knows about the Infinity Stones (Thanos), X and Thor are fighting against Ultron Sigma's army of Xgardians and Ultron Drones, with both lamenting on the damage Ultron Sigma had done overall to their lands. When Ultron Sigma finally appears, the team tries to take him on, but to no successful avail. Captain America boosts X up for a direct attack on Ultron Sigma, but Ultron Sigma easily blocked it and knocked X down. Ultron Sigma was about to slice a downed X, but Iron Man blasts Ultron Sigma on time, only for Iron Man to get knocked down. With the team assembled, Doctor Strange creates a portal and the heroes escape.

The team regroups at Avengers Tower to discuss their plan of attack. With Thanos in their captivity, they use his information to track down the four other Infinity Stones, spread across various parts of the merged universes, and they split to gather them. X is assigned to locate the Power Stone, which is powering the core of Knowmoon. Strider Hiryu and Gamora serve as a distraction while X, Rocket Raccoon, Captain Marvel and Nova go after the stone. X and Rocket stay behind when they encounter a reprogrammed Zero and confront him. They manage to defeat Zero, undoing the rewriting altogether, and they reunite with the others shortly after the defeat of the one ruling Knowmoon, Grandmaster Meio.

After Rocket Raccoon takes the Power Stone, Knowmoon's Gravitron Core, which is filled with the Sigma Virus, is ejected and set on a collision course for New Metro City, where the rest of the heroes are fighting a giant symbiote monster. X's team do what they can to stop the core, but they are unable to damage it or slow its descent and are called back to Avengers Tower after it reached Earth's atmosphere. Thanos hatches a plan to kill two birds with one stone. He teaches Iron Man, X and Zero how to harness the Mind, Time and Power Stones acquired to destroy both the Gravitron core and the symbiote monster plaguing the city. Though they succeed, the destruction of the Gravitron was to close to the city, releasing the Sigma Virus with the heroes at the epicenter of it, infecting everyone. They consult Dr. Light's hologram, but he is unable to deduce a way to slow or halt the infection, the only possible solution being the destruction of Ultron Sigma himself. Reunited, X and Zero gear up together for the fight ahead while Iron Man and Thanos get to work on building a weapon that could deal a decisive blow to the robot tyrant by using the Infinity Stones.

Taking the fight to Xgard once more, X, Zero and the other heroes manage to finally break into the stronghold to confront Ultron Sigma in his lair while Iron Man and Thanos finish making the weapon. Before facing Ultron Sigma, they have to deal with a Sigma Virus-infected Thor, but when Thor is freed from Ultron Sigma's control due to the Soul Stone and Ultron Sigma changes into Ultron Omega, Thor, X, Captain Marvel and Dante team up to weaken him. Iron Man then arrives and summon the new weapon, which he names the Infinity Buster, and gives it to X. X is unable to hold the strength of the buster even when powered up, however with the assistance of Doctor Strange and Morrigan, X was able to be strong enough to fire the Infinity Buster and destroy Ultron Omega, ending the monstrous dictator's rule and the Sigma Virus infection.

Trivia

 * One of X's taunt quotes is a reference to Zero's "what am I fighting for" quote from Mega Man X4.
 * One of Zero's alternate colors in Marvel vs. Capcom 3: Fate of Two Worlds was based on X. As X appeared as a skin for Zero in its updated version, Ultimate Marvel vs. Capcom 3, the blue palette was removed, in favor of a color scheme based on X's first armor instead.
 * X's battle pose in Marvel vs. Capcom Infinite heavily resembles his sprite in Mega Man X, Mega Man X2 and X3.
