"You can't even lay a single scratch on me. Move on before you get hurt."
Zero is the character from Capcom's Mega Man X series and the main protagonist of the Mega Man Zero series.
Zero was created by the late Dr. Albert Wily sometime in the early-21st century. His first chronological appearance was in the form of schematic blueprints during Bass's ending for Mega Man 2: The Power Fighters and described by Wily as his "greatest masterpiece." Learning from his past mistakes, including the accidental creation of Bassnium, and his construction of Bass and King, Wily constructed a new robot, far more advanced than anything he had ever built before with a power level far superior to that of Bass or Mega Man. Wily took the time to complete Zero, originally planning to use him against both Mega Man, and his insolent rebellious Bass. However, this never happened, and he was never utilized during the Wily Wars.
Zero was routinely activated in a semi-conscious state during his construction, and Wily conversed with him, mirroring what Light himself did with X. Zero was aggressive and disobedient, and because of this Wily decided to seal him in a capsule.
Decades later, in the early 22nd century, he was awakened by a group of Reploids prior to the first Mega Man X game. When he was first activated, he awoke as a Maverick (by the definition of wanting to cause harm to all humans) and destroyed all intruders who had dared to enter Wily's lair. Zero was later cornered by Maverick Hunter Elite, Gamma's Maverick Hunter unit inside an unknown facility, however at the cost of a total loss of said unit. Not wanting to get anymore comrades endangered by the powerful enigmatic Maverick, then-Hunter Commander Sigma himself challenged Zero in a fateful one-on-one battle. Even though Zero eventually gained the upper hand during the battle, Sigma was able to defeat the red Maverick after the gem on Zero's head began to glow and a 'W' symbol appeared, apparently causing Zero great pain. Sigma punched this crystal, shattering it and defeating Zero (subsequently passing on the Maverick Virus to himself). He was then brought to Dr. Cain, who analyzed him.
After that, Zero recovered from his battle with Sigma and was placed under Sigma's watch. Zero did not show any signs of Maverick behavior and was enlisted into the Maverick Hunters' 17th Elite Unit. Zero had sacrificed his life multiple times as a Maverick Hunter and was usually rebuilt or repaired as soon as possible.
However, towards the end of the Maverick Wars, Zero submitted his body had been examined by the top scientists, and his conscious, or control chip, was seperated from his body. A cure for the Maverick Virus was discovered. The cure was made into an entity known as the Mother Elf, and the scientists used the Mother Elf's energy to create Cyber elves that were used to spread the cure. However, Dr. Weil, one of the researchers, was power-hungry, and had stolen Zero's body and the Mother Elf. Weil created a Reploid of pure evil named Omega, who inhabited Zero's body.
Weil then corruped the Mother Elf, turning her into the Dark Elf, and used her to control other Reploids. Meanwhile, the other researchers constructed a new body for Zero. This body was potentially even stronger than Zero's original body, and when his control chip was inserted into the new body, he began to fight alongside Mega Man X in the Elf Wars. The war was so large that 90% of all Reploids and about 45% of all humans were killed in the war. In the end, Omega was sent into space, and Weil was exiled from Neo Arcadia, a utopia for reploids and humans ruled by X. Zero, deciding that it was his own fault that these wars happened, decided to seal himself away for good. However, the Dark Elf was still at large, and X sealed himself away to restrain the Dark Elf.
This would lead into the Mega Man Zero series, which takes place in 23XX, in a dystopian future. Zero is awakened by Ciel, the leader of the Resistance against Neo Arcadia. It is revealed that the ruler is Copy X, an imperfect copy of Mega Man X created by Ciel while the real X, now a cyber-elf, wandered around the Earth aimlessly. Years earlier, during an energy crisis, Copy X decided to label innocent reploids as Mavericks and exterminate them. Copy X was also served by the Four Guardians, known as Sage Harpuia, Fairy Leviathan, Fighting Fefnir, and Hidden Phantom.
After destroying Copy X, resulting in the death of Hidden Phantom and the defeat of the rest of the Four Guardians, the fortress in which Zero and Copy X self-destructed, and Zero was presumed dead by the Resistance. Though, in reality, he has been wandering around the desert aimlessly for a year. Eventually, he is found by the Resistance, and taken to the new HQ.
Under the command of the new commander of the Resistance, Elpizo, Zero continued his duty by destroying Mavericks that were a threat to the Resistance. Meanwhile, Elpizo had been planning Operation: Righteous Strike, in which he believes the only way to acquire peace is to destroy Neo Arcadia, though Ciel and Zero were against the idea.
However, when he finally carries the operation into motion, it quickly goes horribly wrong when the Resistance soldiers involved in the operation were quickly killed by the three remaining Guardians. Having gone mad by the death of his soldiers and his absolute failure as a commander, Elpizo leaves the Resistance, and decided that he would make it up by unleashing the power of the Dark Elf to destroy Neo Arcadia.
Making his way into Yggdrasil, the location in which X's body was holding the Dark Elf, Zero had reached Elpizo, but it was too late. He had already gone mad and absorbed the power of the Dark Elf after destroying X's body, while also possessing the power of the Baby Elves.. After a fateful battle, Zero defeated Elpizo, who realizes the wrongs of his actions, and asks for forgiveness. However, the Dark Elf, turning good briefly, saves Elpizo from death by turning him into a cyber-elf.
As Zero continued his duties as with the Resistance, under the command of Ciel, he encounters a powerful Maverick named Omega on one mission, who easily defeats the Guardians. Zero and Omega engage in combat, but are interrupted by Dr. Weil, who has returned for revenge, as well as Copy X MK-II, a stronger and more advanced, yet still mentally imperfect, clone of Mega Man X.
Being endlessly loyal to X, or anyone like him, the Guardians side with Omega, Weil, and Copy X MK-II. While diverting Zero's attention by summoning several Mavericks to fight the crimson warrior, Weil spent his time looking for the Baby Elves. After persuading them to side with him, Neo Arcadia launches a missile at a small town to enable Omega to find the Dark Elf, Zero goes there and attempts to stop it, but fails, and Omega fuses with the Dark Elf, making him all the more powerful.
However, during an assault on Neo Arcadia, Zero makes his way to Copy X MK-II, where they fight. Zero defeats him, but after being completely destroyed by a built-in failsafe system by Dr. Weil, the real X, still a cyber-elf, reveals to Zero that Dr. Weil had apparently planned to use the failsafe system to frame Zero for the death of the ruler of the human utopia, and also ensures that Weil becomes the leader of Neo Arcadia.
Zero then proceeds to make his way to confront Weil. After terminating the Baby Elves, he went on to fight Omega in three different forms, the last having Omega in Zero's original Mega Man X-era body. After an intense fight, Zero manages to defeat Omega with the help of the Guardians, but the Dark Elf appears, creating an energy barrier around Omega, protecting him.
However, Zero manages to bypass the barrier and destroy Omega. The explosion is so massive, though, that it killed everyone nearby, except Zero, who was recovered by the Resistance. Also, with the death of Omega, the curse upon the Dark Elf has been lifted, and now she is pure of heart, once more becoming the Mother Elf, and flies away. Ciel explains that Zero survived because he was protected by the Mother Elf.
Meanwhile, Dr. Weil's tyrannical rule over Neo Arcadia has caused a several humans to flee, and start a settlement in Area Zero, which happened to be the crash site of Eurasia. The Eurasia Incident (Mega Man X5), happened to be the cause of Zero's death/disappearance for three weeks back in the Maverick Wars.
The humans fleeing from Neo Arcadia are attacked by Variant-brand Mavericks controlled by Weil, but Zero destroys the Mavericks, and the humans step out. One of the humans, a reporter named Neige, thanks Zero cautiously, but warns him to stay away from the settlement, as Reploids aren't welcome. When Ciel asks why, Neige explains that humans hate and resent Reploids for bringing war and death for over two centuries.
After a Maverick disturbance is detected near the settlement in Area Zero, Ciel dispatches Zero to quell the disturbance. After destroying the Maverick, he is stopped by 8 more Mavericks, named the Einherjar, and their leader, a mysterious Reploid named Craft.
After being sent on several missions, all of which involving destroying the Einherjar, he confronted Craft during a Maverick attack on the Area Zero settlement. After the battle, Craft realized Dr. Weil was the villain, and disappeared.
Zero confronted Craft again on a space station called Ragnarok. Craft reveals that he believes that the best way to eliminate Dr. Weil is by firing a giant laser beam at Neo Arcadia, where Weil presumably resides. Zero attempts to stop him, but fails, and the laser kills most of the residents of Neo Arcadia. However, Zero does manage to terminate Craft once and for all.
When Zero is transported back to Earth, it is revealed that Dr. Weil survived the blast, and now controls Ragnarok. As Zero returns to Ragnarok for his final clash with Weil, the spaceship begins to crash into Earth due to Weil fusing with the core of Ragnarok. With the space station heading straight for Area Zero, Zero is the settlement's last hope.
In his last battle, it is also revealed that Zero does not have enough time to escape if he survives his clash with Weil. Zero figures out that by destroying Ragnarok's core, Ragnarok will explode while still in orbit, and Area Zero will be saved. In a last act of noble courage, Zero sacrificed himself once and for all, destroying Weil, Ragnarok, and himself.
The ultimate result of the infamous Dr. Albert Wily's research, Zero was built with the intention of surpassing anything Wily had built before, and to destroy his long time nemesis's creation, Megaman, as well as his own misguided creation, Bass. Being made before the introduction of standard mass produced Reploids and during the construction of X, his internal processes and construction are considered to be more advanced than most known robotics and on par with X's parameters and capabilities.
He is initially outfitted with an armament known as the Z-Buster, an arm cannon capable of firing of blasts of energy as well as manipulating it to launch it in special variations and projections.
During the X2 series and onward, Zero adopts and becomes the user of the Z-Saber, a beam sword that became his trademark weapon. Not only capable of manifesting itself as a beam of light, it is also capable of changing its consistency, ranging from from different wavelengths of frequencies, different states of energy, including pure electricity, ice, and fire, and to even various mass compositions, including metal, crystal, and even foliage, to suit a variety of situations in combat and on the field.
Zero is also outfitted with the Learning System, a system not unlike the Variable Weapons System in its copying and adaptation of certain weapons, but adapts various abilities and techniques of opponents and enemies, and even goes as far as copying the kind of power and possible energy projection emitted from the attack.
As an android created by Dr. Wily, he possesses superhuman strength, speed, and durability. All Reploids possess these attributes, but it is unknown on how stronger they are than humans exactly.
However, underneath his exterior displays of ability and performance, just like X, Zero holds an immense and potentially limitless capability for adaptation and power. Via his power grid and many gameplay incarnations of him, Zero is a traditional Glass Cannon (weak on defense but strong on offense) as in the main Mega Man games, most of his attacks did an immense amount of damage. But in his fighting game counterparts, Zero has his traditional low health, but makes up for it with great combo potential and versatility despite not being overly strong. Thus, it can be stated with Zero's swordsman skills and with his other abilities, Zero can adapt to practically any foe he fights, and his long combos tend to show Zero often and always fights at his best and does not tolerate holding back.
The reason for his low health is mainly due to his creator and Dr. Light being unable to provide future armor upgrades for him that involve his durability (barring the secret Black Zero armor), and thus his defense mainly stated consistent through out the Mega Man X series. Despite this, he makes up for this with skills in other fields/strengths and great adaptation to many situations.
A hardened soldier, he is a war torn veteran, and is cold, calculated, and ruthless on the battlefield. Once a competitive and daredevil Maverick Hunter, devastating events and close tragedies of those close to him and related to the Maverick Wars brought him to light the sorrows and suffering of the conflict. However, he knows when to show restraint, and can easily tell right from wrong. He comes off as sarcastic and distant, even to his closest allies X and Axl. However, deep down, he is caring and would always put his life on the line for his friends, no matter the consequences. This can be proven by the fact that Zero dies a total of two times in the X series alone, three if you count the non-canon scenario of Mega Man X5 where he sacrifices himself to protect X from Sigma.
He also acts as a mentor to X and Axl, and is a competent leader, being the commander of the Special 0 Unit of the Maverick Hunters. Outside of his duties as a Maverick Hunter, he yearns to find out about his past.
However, in the Mega Man Zero series, his personality is a bit different, possibly due to his amnesia. He is far more silent, having very little lines in the first Mega Man Zero game compared to the rest of the series. He doesn't show a solid personality in this series, though at one point in Mega Man Zero 3, when his friend Ciel begins to question her own actions, Zero assures her that what she is doing is right, and inspires her to continue going on. Later on in the series, he eventually regains his memories, but having experienced a lot in his lifetime, he remains taciturn and without much to say.
His future personality also shows signs of deep indifference and coldness to those inhospitable to him and his friends. In Mega Man Zero 4, he and Ciel attempt to warn the human residents of Area Zero, the last habitable place on a devastated Earth, of the grand threat of the powerful Ragnarok satellite cannon. Faced with much resistance, and their complaints of how Reploids, their wars and destruction that potentially destroyed the world, and how Zero is nothing but the cause of the series' conflict, he leaves them, while telling Ciel that the humans have been warned, and that it is up to them to decide whether to evacuate or be destroyed by Ragnarok. Despite this, he also has much hope in humans, as he believes it is within them to change the world for the better.
Lastly, the most notable difference in terms of personality between his Mega Man X incarnation and his Mega Man Zero incarnation is that the former fights for justice and peace as a Maverick Hunter, while the latter fights on his own accord, refusing to be acknowledged as a hero. There at also hints of him believing in fighting at full power, as Zero's never one to hold back in fights.
In his Mega Man X incarnation, he sports blue eyes, a blond ponytail with a blue band, as well as a red helmet with several "horns" and a blue, triangular energy crystal in the center of his helmet. His body is the standard build of a reploid, despite the fact that he is technically an android, as a reploid is a replica of X built in 21XX. As of Mega Man X2, he also has shoulder guards with the letter Z on both of them.
In his Mega Man Zero incarnation, his appearance is sleeker and more human-like. Like most of the characters in the Mega Man Zero series, he sports a vest that he wears over a skintight bodysuit. The energy crystal located on his helmet is now green, and he now has black eyes. His skin is also paler.
"This will be over in a nano-second."
—Spoken before battle
Zero plays similar to his TvC counterpart, and is versitile as a Rushdown/Cross-Up Point character. Zero's normal attacks and special moves don't do a lot of damage on their own, but are meant to be strung together in super-long and highly damaging combos. When facing a skilled Zero player, one opening from you can allow Zero to perform an extremely long combo that could potentially take away more than half of your lifebar, as well as being able to sport an interesting amount of pressure from said strings, to the point where Zero can build meter at a great rate with amazing hit confirms. The only notable changes for TvC veterans are that most of Zero's original crazy loops are gone (along with some of his original bread & butter combos), and in that his neutral game is quite improved to the point where Zero is no longer over-reliant on pressure, thus Zero can fight from both far and close better than before, being able to put pressure from afar with his Hadangeki and Zero Buster. Zero can still loop like in TvC, but his loops now require different methods of execution, which his new Raikousen move can be of great use. Also, his Hyper Combos have also been adjusted to be far more practical in their usage (especially Rekkouha), making Zero's combos more damaging overall than in TvC.
In gameplay, Zero mainly uses his trademark weapons, the Z-Saber and Z-Buster. He also performs a wide variety of attacks and techniques that he gained during the X series. As a homage to his X series specs, Zero is has quite a low defense rating (or in this case, a low health rating). Get hit by a powerhouse and he's done for in 1 or 2 combos, so be careful about getting hit. or extending brutal combos. He also seems to lack quick mix-ups due to no overhead command normals, though his H.Hienkyaku can sometimes help with that. Using Zero requires him to be on the move at all times, ready to know what move to use; looping with Zero requires good execution as well as learning how to stick his Hyper Zero Blaster in combos by drumming to other buttons to hold down during a charge in a combo (which is mitigated by his amazing hit confirms with moves like his standing and jumping H). Learning how to utilize all his attacks to their fullest can make him dominate most opponents like the S-Class Hunter he is. With his neutral game in mind, due to Zero being a "weapon/sword character", his hitboxes can lead into abare-types of combos, which are combos that can be done off of any random hit confirm; in the hands of combo-happy experts with a knack for tight execution, this can make Zero rather deadly and put his foes in a cautious state.
Along with the new game systems, Zero is also no longer has any easy escape options, since there are no combo breakers in MVC3 like with TvC's Megacrash (Zero players could build an insane amount of meter off a few combos, and thus could shut down many of their opposistions' offenses). And now he is a more tolerable threat than in TvC. Another notable loss for Zero is that his air dash is slower, and that he can no longer double jump like in TvC.
A few unique things that have applied to Zero are that his 2C/crouching H does not hit low. His dash is also a run, in that he can continuously run for as long as the player holds the direction Zero is running, making him strong at tech chasing and making very versatile in controlling his running unlike other characters who must wavedash to either move fast (which Zero lacks) or be able to stop. Also, unlike Viewtiful Joe (and like Frank in UMVC3), Zero's jumping H no longer finishes air combos, and gains a new air combo/aerial rave finisher in its place instead.
Ironically similar to his SvC version, Zero also has a jumping DP special loop, with his Raikousen. Unlike the original midair Triple Rod infinite, this loop involves getting a knockdown in the corner, and spamming a Sougenmu mode L Raikousen on his foes. Raikousen alone near the ground can also be used for powerful crossups or juggles in air combos.
In UMVC3, most of his normals have been nerfed in that they have less hitstun. Though one would think his combo potential has lowered, but now his zoning potential has increased. His Hyper Zero Blaster despite its knockdown nerfs can now be fired off from any of Zero's attacks and can be charged at the start of the round (as a nod to his original series, where one can do so before entering a boss area and during a cutscene before said fight), but the latter function combined with moves such as his Raikousen can make zoning a fair breeze, as well as make moves such as his Sentsuizan more useful in combos. Along with a slight health buff, Zero like with his TvC version ascends the high-tier thrones once more thanks to his new capabilities.
(Note: Some spellings use the extra "o" and "u" romanizations, and some are romanized without them.)
- Shippuga (Hurricane Fang): Turning dash slash attack from MMX4, now colored orange instead of pink. Meant for BnB combos (especially during juggles), can now cancel into a launcher. This move seems to pack less range than in TvC, and the assist version does one hit instead of three hits with Zero running up a small bit before performing it.
- Kuenzan (Air Circling Slash): Zero's jumping H/C attack. Zero performs a frontward-somersaulting slash in midair. Comes from MMX4, but variations of this move appear in other Mega Man games involving Zero's appearance. If performed as 2C during a jump, Zero will perform the Kuuenzan while facing backwards (possibly as a reference to how Zero can turn directions when doing a rolling slash in the original MMX games). Works as a powerful crossup tool, even if Zero doesn't use the reverse version.
- Hyper Zero Blaster/Zero Buster: Holding A, B,C or Dash makes Zero charge his buster, and releasing it makes him fire it. Can be used in midair, where Zero fires downward instead (but cannot OTG). If all three buttons have been used to dash, you cannot use other attacks until released. It can now pierce the opponent for 3 hits, and flies more faster when fully charged and has different colors (colored either green, blue, or yellow instead of blue mixed with yellow). It is a very useful attack in terms of extending combos, and can cancel into other special attacks. Origin is MMX3, which is the only MMX game where Zero can use his Z-Buster while at the same time is given the feature of charging it. The charge took a total of 6 seconds to fully charge in TvC, but in MVC3, only 3 seconds is required.
- Hadangeki (Wave Severing Attack): Fires a wave from his sword via an outward downward slash. The H version fires two waves in very quick succession via a cross wave done by Zero slashing inward back in an instant. Origin is MMX7.
- Ryuenjin (Dragon Flame Blade): A flaming sword rising uppercut. Comes from MMX4. As of MVC3, this move can't be used in the air since the input command for this is the same as Raikousen which is an air only attack.
- Sentsuizan (Spinning Crasher Slash): An aerial version of Shippuuga from MMX6, which is a diving slash attack in midair. the L/A version is a fake move that can be canceled into an attack, where Zero draws his saber's hilt but quickly places it back over his shoulder. Causes stagger on grounded opponents and finishes air combos/aerial raves in midair, as well as OTG the opponent off the ground. The startup for this attack on all versions has Zero pause in midair for a bit, stopping his momentum.
- Hienkyaku (Flying Swallow Feet): A dashing teleport move from MMX4 that leaves behind red-shadow afterimages, but provides no invincibility. Can dash in two different directions on the ground, or three in midair. Used for crossups and other certain practical uses, such as extending combos and mixups. Zero's feet now shoot jets as an added effect.
- Raikousen (Lightning Flash): Zero dashes with a ripping slash forward with saber extended followed shortly by a streak of lightning, its angle can be changed going three different directions (low, mid or high). Comes from MMX8 although its color is blue now instead of violet, Zero is now also visible during the entire attack. The lightning streak itself is not a physical portion of Zero's hitbox, and is actually an energy attack, meaning Advancing Guards will not displace it. Can be used for crossups if Zero passes behind the opponent at times.
- Rekkoha (Rending Light Supremacy) (Level 1): Giga Attack from MMX6. Punches the ground with a charged up Z-Buster, bringing down a salvo of rainbow-colored pillars of energy onto the opponent. Can hit OTG. The pattern of the beams is changed from TvC (from a row of raining forward beams to a complete hailstorm in a contained vertical area), and Zero is also no longer invincible during startup. This attack is rather useful for midair DHC's if the opponent has been struck with a Hyper high in the air, as the beams will appear on screen sooner.
- Sougenmu (Twin Phantasms) (Level 1): Creates a shadow copy of himself that mimics his actions and doubles his hits from attacks. The shadow is now colored gray as opposed to blue, and now imitates all of Zero's actions instead of just special moves (other than Hienkyaku). Power up attack from MMX5. Appears differently than in MMX: Command Mission, where the shadow was colored red and the attack was named Heat Haze. Cannot build meter in this state, though Zero's assists are doubled as long as this move is still in effect if he is tagged out.
- Ittou Ryoudan: Genmu Zero (One-Bladed Double Severing: Phantasm Zero) (Level 3): Draws his saber, gives off a familiar red glow and leaps up to pivot himself before launching a huge, supersonic energy wave from his saber. Based from MMX5 when fought as a boss, namely the 'Maverick' form of Zero (hence his red aura). The term used during the attack, 'Ittou Ryoudan' is the art of cutting an opponent in two with a single stroke, and also references its use as an instant killing attack in its debut. Also one of the few Hyper Combos to do only 1 hit. Cannot OTG, despite its appearance.
- Reploid - Clear Arcade mode with Zero on any difficulty
- A-Rank Hunter - Clear Arcade mode with Zero on Very Hard
- Maverick Hunter - Complete 5 missions with Zero
- Special Zero Unit - Complete 10 missions with Zero
- Level-Headed - Use Zero 30 times
- I Prefer Swords - Use Zero 100 times

Theme SongMarvel VS Capcom 3 - Zero Theme(03:54)
Zero's theme is a remix of his battle theme from Mega Man X2.
|Zero's ending has him hitching a ride with the Silver Surfer back to his own world. Silver Surfer, instead, accidentally takes Zero to Neo Arcadia, the setting of the Mega Man Zero series, due to him not being able to tell the two apart (as they are essentially the same world in a different time). They soon travel to a different world in order to take Zero back to his homeworld.
Silver Surfer: We're here, finally. Our journey was a long one.
Zero: Thanks for the lift. Sorry for all the trouble.
Silver Surfer: I was happy to be of assistance. So this is your home, isn't it? A very futuristic city indeed. Neo Arcadia, was it?
Zero: Yes, this is indeed Neo Arca... ...Wait, something is not right.
Silver Surfer: Sorry, but this is the wrong world. This seems to be the world of MegaMan Zero, according to my data.
Zero: I'm Zero, not MegaMan Zero.
Silver Surfer: Perplexing indeed. I cannot tell the difference between any of these worlds. The next dimension may have a world similar to this one. Shall we try again?
Zero: Yes, and sorry for all the trouble.
- This is the fourth time Zero has appeared in a Capcom crossover game; he debuted in SNK vs. Capcom: SvC Chaos (in his form from Mega Man Zero), Onimusha: Blade Warriors (again in his MMZ form) and Tatsunoko vs Capcom: Ultimate All-Stars, but it is the first time he has ever made it to the Marvel vs. Capcom series. All these listed games have Zero as a hidden/mid-boss character, while save for MVC3, where Zero is introduced as a starter.
- He also gains a modified version of Raikosen from X8.
- Because of this, he now has one attack from every main series game he has been playable in.
- His Level 3 hyper is the infamous Genmurei (yelled here as "Genmu Zero!") from the equally-infamous X vs. Zero battle from Mega Man X5. This also doubles as a Bilingual Bonus, as Genmurei literally translates to "Phantasm Zero".
- Zero briefly gains Awakening Zero's crimson Battle Aura during said hyper, however, it is possibly due to the fact that Zero is not under the virus is the reason why the Genmu Zero is yellow instead of green, and why it fires one wave instead of two like in the boss fight.
- A very subtle reference also comes from the color of his Z-Saber during Genmurei. Zero's Z-Saber can obtain a power-up from one of the Mavericks via his Tenkuuha (Aether Supremacy) ability (or in the case of in X5 and X6, from power-up parts) in several games (these three cases turn his saber purple), allowing him to deflect projectiles (the only exception was X7, where he had this augment from the start). In X8, beating Earthrock Trilobyte earns you the technique Rekkyoudan (Violent Mirror Severing), which gives the Z-Saber a yellowish-orange glow. During his Level 3, the Z-Saber exhibits both of these properties.
- Zero's Hadangeki and Genmu Zero are inversed in color in MVC3; the original Hadangeki was yellow in color, while Genmu Zero during Awakened Zero's X5 boss fight was green. However, Hadangeki was already green in TvC.
- His alternate color schemes are based on X, Axl, and his "brother" Bass. For Ultimate, he loses his X scheme for another one based off X's first Armor, and gets two schemes based off Vile and his Mega Man Zero design. His DLC costume is X himself.
- His character theme is a remix of his Boss Fight theme from Mega Man X2.
- In his ending, Zero also mistakes Silver Surfer's addressing of Mega Man Zero (as in the series, not Zero himself) as the title the Surfer gives him and quickly corrects him on it. This was one of the many problems found in a manga adaptation of Mega Man Zero.
- Zero in his X-Factor mode can be seen as a nod to Maverick Zero, in the infamous X vs Zero fight in X5.
- Zero's alternate color schemes are based on his allies X and Axl, as well as Bass (another robot built by Dr. Wily and Zero's technical brother). One of the updated alternate color schemes in UMVC3 is based on Vile, a recurring villain in the X series (in his X1 colors), while the others are based in X's super armor from the first game and the Mega Man Zero color scheme.
- All of Zero's attacks came from each of the MMX series games he was playable in from MMX3 to MMX8.
- The Hyper Zero Buster originated from Mega Man X3, while Shippuuga, Hienkyaku, and Ryuuenjin originated from Mega Man X4. The Sogenmu and Genmu Zero techniques came from Mega Man X5, while Sentsuizan and Rekkouha came from Mega Man X6. The only move that originated from Mega Man X7 was Hadangeki. Raikousen originated from Mega Man X8. Also, his standing L, M, and H in that order is a nod to Zero's basic saber combo pre-MMX6.
- Zero is one of only 6 characters (the other being Hsien-Ko, M.O.D.O.K., Spider-Man, Super Skrull and Shuma-Gorath) in the game to have a special quote fighting himself. This is due to him fighting "himself" in some games, namely in an opening cutscene in X5, and the Zero Nightmare in X6, as well as the Copy Zero from Mega Man X2 which Zero will destroy if X manages to have him repaired before that battle.
- Zero confuses Sentinel for a Maverick - a term used in the Mega Man X series describing a Reploid that desires to harm humans (this is partly true as it was made to combat human mutants, but not nessearily humans in general).
- Zero is considered the replacement for Mega Man in representing the series on MvC3. Zero is also considered the replacement for Hayato as well: both have similar fighting styles focusing on the energy sword.
- Niitsuma, the producer of MvC3, announced that he replaced Mega Man with Zero because he felt Zero had more variation in his moves.
- Zero is the only character out of the 3 who came to MvC3 from TvC with minimal changes to his actual model design aside from color fixing, the other two being Viewtiful Joe and Frank West. Zero's only changes involved his hair being to its usual length and form (in TvC had it somewhat thinner like in Mega Man X8), along with the aforementioned one-hand-open X6 stance. Joe's TvC model was exactly from his games (though he faces more forward towards his foe in MvC3's case) while Frank's face gets some changes. Also, in terms of gameplay, Zero's neutral game is more improved, making rely less on pressure like in TvC (where he was considered high/top-tier.) All three characters even improve greatly on their offensive games (More so for Frank and Zero).
- Both Frank and Zero have jumping C/H's that are normal midair attacks rather than air combo finishers (they instead have new ones), while Joe's original jumping C/H is now his j.S, while receiving a new j.C/H. In Frank and Zero's case, the same also applies to Ryu and Chun-Li, though the latter two are long runners in the series.
- In Ultimate Marvel vs. Capcom 3 one of his new win quotes can contextually be taken as a reference to (or even something of a jab at) the huge demand for Mega Man X: "If X were here, he would have tried to talk things out first. Unfortunately for you, X isn't here." Although it's highly likely the line is meant to be Zero suggesting to his opponent that if X were present before the fight it -along with their defeat- might not have happened at all, due to X's famous technical pacifist nature. Ironically enough, X himself is his DLC costume.
- Zero is also the only TvC character to keep a Level 3 Hyper after being transitioned over to the Marvel vs. Capcom series. His original Level 3 Hyper was the Dark Hold, where he would stop time after slashing his opponent with a rushing slash to hold them in place, then run them through with a enlarged Z-Saber in the shape of the one from the Zero series.
- Both his Level 3 Hypers even come from the same game of origin, Mega Man X5.
- Zero is classified as one of the shorter characters in-game, though he is actually estimated to be around 5'8 or 5'9. He is even called "an angry space midget" by Hawkeye. He is shown to be slightly taller than Wolverine, who is 5'3, and around the same height as X-23, though she is 5'6.
- Zero's alignment may be in question. When he was first awoken, he was violent and disobedient towards his creator, Dr. Wily, and caused destruction everywhere, leading him to be sealed away for a century. Because this incarnation of Zero is the Mega Man X series incarnation, he is a Maverick Hunter who protects the innocent. However, there have been occasions where he has been turned to evil (though these events are non-canon), and fights X. However, in SNK vs. Capcom: SvC Chaos, he is in his Mega Man Zero incarnation, and was quoted saying "Humans are my enemy. Enough of this. Shall we?" as pre-fight dialogue. In the final battle against Dr. Weil in Mega Man Zero 4, he is quoted saying "I never cared about justice, and I don't recall ever calling myeslf a hero. I have always only fought for the people I believe in. I won't hesitate. If an enemy appears in front of me, I will destroy it!"
- Zero is shown to be ambidexterous; his Z-Saber in real canon (more so than in his artwork than in his sprites and in MMX8) is sheated over his left-shoulder (the aforementioned makes him show it over his right shoulder instead), yet despite being right-handed most of his normals involve using his left-hand to slash with his saber (in terms of facing to the right that is).
- Zero has the most voice actors in all of his appearances (most of them in English), though in the Vs. Capcom series so far he's only had 3 different ones on average like most others (In both Japanese, which are Ryoutarou Okiayu for his X incarnation and Yuuto Kazama for his Zero incarnation, and one in English).
- Zero's MvC3 English Voice Actor, Johnny Yong Bosch, seems to make Zero via in name play homage to his other roles, including Nero from Devil May Cry 4 and Lelouch Lamperouge/Vi Britannia from Code Geass. Some take it as a casting joke, while others take it a bit offensive in terms of Zero's casting from the MMX series.
- Zero's ending in UMvsC3 is slightly changes so that after saying he isn't Mega Man Zero, he says right after if someone like that ever existed, which is semi-ironic, since both Zero and "Mega Man Zero" are essentially the same being, just in different time periods.
- But Zero himself doesn't know this since his incarnation in the game is his Mega Man X apperance, and his Mega Man Zero apperance never appers in this game.
- Zero in the original released version of MVC3 had a snapback glitch with his Sougenmu, where if only Zero's shadow connected on a target during his Shippuuga animation (if any of their assists were on screen), the foe would fly out but no one would be tagged in, thus making Zero or his teammates all alone on the field. This lead to very cheap time-outs with such an exploit, and was removed in the update patches. (Zero's Sougenmu would end if he used a snapback).
- Zero in UMVC3 is one of the few characters without a hyper that can be button mashed for more damage.
- When pitted against Frank West, Zero will call Frank "a civilian" at the start of a fight, and when Zero defeats Frank, he'll make a Dead Rising reference using Frank's catchphrase "I've covered wars, you know!" (i.e. Zero will say "You may have covered wars, but you're still a civilian.") and comment about his eyes and brain being "so weak that he must rely on a photon-capturing device", probably because he did not know what camera was due to the fact that in his universe, there is no camera.
