MegaMan.EXE

"Let's bust some viruses!"

- MegaMan.EXE

MegaMan.EXE, known as Rockman.EXE (ロックマンエグゼ) in Japan, is the NetNavi (short for Internet Navigator) operated by Lan Hikari. He was created by the scientist Yuichiro Hikari, Lan's father. MegaMan.EXE is very powerful, and along with his operator Lan, is a very skilled virus buster. He is also Lan's twin brother, Hub Hikari, known as Saito Hikari (光 彩斗) in Japan, who died at birth, because of a rare heart condition known as HBD. Dr. Hikari then used his data to revive him as a NetNavi, MegaMan.EXE.

Personality
MegaMan is very loyal to Lan and is willing to sacrifice himself to save him in Mega Man Battle Network 3. Their friendship also allows for powerful abilities like Full Synchro and Cross Fusion. MegaMan is also more responsible than Lan, reminding him to do his homework and waking him up in the morning for school. They do argue sometimes, like in Mega Man Battle Network 2, but they always manage to reconcile. In the anime, he also displays a fear of ghosts, which doesn't appear in the games. In the manga, he, along with Lan, enjoys Net battling, always getting excited whenever a strong opponent appears and aim to be strongest. This, however, can also make him reckless to the point that can be nearly considered as suicidal since he charges straight at his enemy even though his opponent is clearly stronger than him.

Description
MegaMan is small (for a NetNavi), but his abilities are many. He has indigo biceps, with cyan stripes down his sides, ending at his blue boots which are tipped with black soles. He has two yellow shoulder guards and his blue helmet has two ridges running along the top. These ridges come to a stop at the helmet's base and allows his dark hair to stick out in four spikes. He has green eyes and, unlike most other NetNavis, an overall human appearance. As a customized NetNavi, MegaMan sports the symbol of the Hikari family on his chest and both sides of his helmet. This symbol is a red circle with a black line running diagonally through the center which ends in two triangles, all of which are surrounded by a gold ring. MegaMan stands at 148 virtual centimeters (roughly 4'9").

In the games and in the manga, MegaMan is shown with a faceplate covering his mouth and nose when in battle and in most of the Battle Chips with images of him. In the manga, in some stories, MegaMan dons on the faceplate when he usually finishes off an enemy Navi. In the anime, this kind of facemask closes when MegaMan equips a sword or shotgun. It is revealed that MegaMan has brown hair under his helmet.

Game History
MegaMan.EXE is a unique NetNavi in the fact that he is the ultimate result of the Navi Project, an experiment undertaken by all of SciLab and led by Yuichiro Hikari. The Navi Project was designed to successfully graft a human's DNA and soul into a NetNavi. The process took a NetNavi's data and made it able to adapt to almost any situation. Yuichiro was only able to create about 95% of the actual project but no further when he and his wife had two children: twins Lan and Hub. Hub was quickly diagnosed with HBD and died shortly after birth. To keep Hub's soul alive, Mr. Hikari decided to use Hub's DNA to create MegaMan.EXE and gave the Navi to Lan. As Lan and Hub were identical twins, Lan and MegaMan developed a brotherly bond perfecting Yuichiro's Navi project. However, it was presumed that if Hub's exact DNA were to be used, the 'Twin Link' effect would take place, and any sort of reception of senses that Lan or Hub would experience would affect the other by brainwave synchronization, much like Full Synchro. As such, Dr. Hikari had modified Hub's DNA by .001% (this is presumed to be eye color, as despite being identical, they have different eyes). This remaining .001% was programmed into the Hub.BAT (Saito.batch) if ever the need to reset Hub's DNA to the original was necessary.

By channeling enough power, MegaMan can transform into a holographic version of Hub. Although never shown fighting, Mega Man Battle Network 5 and Hub Style in Mega Man Battle Network 2 infer that this form is immensely powerful, able to defeat bosses like Nebula Grey with just a wave of his hand, cannot be corrupted by Dark Chips, and gains every single Navi Customizer Program without trouble. His only downside is that he loses all possible transformations and the Mega Buster, which probably isn't needed. This form is possibly even more powerful than some of the strongest NetNavis like Bass, Slur, Duo, or even the Super Cybeast. Unlike most characters that need full power to access their powers, if he has enough power, he can temporarily tap into his powers to do outrageous things, like sealing the Cybeast, controlling the Dark Chips influence on him when used, and becoming Bass Cross MegaMan when Bass failed to maintain the fusion and used Double Soul instead of self-destructing.

Throughout the games, MegaMan is used by Lan to Netbattle and communicate with his friends' NetNavis. MegaMan is able to transform into a new form in most of the games and in Mega Man Battle Network 5 and 6 have an uncontrollable form, Dark MegaMan and Beast Out MegaMan.

Anime History
In the MegaMan NT Warrior anime, MegaMan is not related to Lan in any way, shape or form. Being a main character, he appears in almost every episode. MegaMan was created by Dr. Hikari and was given to Lan as a present. He appears in the first episode when Lan uses a disk his dad gave him to customize his NormalNavi. In the following morning, MegaMan wakes Lan up like he usually does in the games. Lan is initially disappointed that MegaMan is small, but when viruses attack, MegaMan displays amazing skill. He quickly made friends with Roll (eventually leading to her loving him) and had a minor rivalry with GutsMan. Throughout the first season, MegaMan and Lan fight against the WWW and make new friends. MegaMan and Lan also have a heavy rivalry with Chaud and ProtoMan.

They later enter the N1 Grand Prix, during which Lan and MegaMan try to master the Program Advance. In the final round, MegaMan and ProtoMan fight each other, with ProtoMan as the victor. However, their battle awakens PharaohMan.EXE who deletes MegaMan. He is later rebuilt and defeats PharaohMan with the help of ProtoMan using a double Program Advance. In the second season, MegaMan and Lan face of against the criminal organization Grave using various style changes.

Manga History
In the MegaMan NT Warrior manga, although not explicitly, there were hints regarding MegaMan's relation with Lan. Mayl once commented that Lan and MegaMan are like true brothers, and Miyu, who is able to read and hear "hearts" of objects sensed that MegaMan has human heart even though he is a NetNavi.

MegaMan was created by Dr. Hikari and was given to Lan as present when he was five years old. Lan was initially annoyed by MegaMan's constant reminding whether it was about his school or behavior and ignores him for days. It was until MegaMan encouraged Lan to get out from a truck that was about to be destroyed while playing hide-and-seek that they finally grew closer.

WWW
The first part of the story focus on MegaMan and Lan's life with their friends and fighting against WWW. MegaMan sacrificed himself when facing against the virus that Willy created, but it turns out that he barely survived in the Undernet and is revived with Lan's help.

Undernet
After sensing various stronger people while he was unconscious in the Undernet, MegaMan becomes interested to enter the Undernet to face stronger opponents and become stronger. This is granted when ElecMan and BombMan cause havoc in a restaurant where Lan and Chaud are and the path leads them to the Undernet. MegaMan and ProtoMan chased after and defeated them in instant. They are interrupted by the arrival of the 'Black Shadow' of the Undernet, Bass. Witnessing Bass' power that beyond them, ProtoMan and Chaud disconnect the Full Synchro and intend to jack out, but MegaMan and Lan charges straight at Bass. ShadowMan saved MegaMan and Lan and revealed that Bass was the one who let them live. He then gave them a map that might help them to power up and disappears.

MegaMan and Lan are frustrated upon seeing the map as nothing more but an badly-drawn picture and try to think of another way to reach the place that ShadowMan mentioned. A Mettol appears and asks for MegaMan's help, dragging him to a Mettol village in the Undernet with GateMan's help. Apparently, Mettol village is terrorized by a mysterious tornado that has been destroying the village and the Mettol asked for his help to get rid of the tornado. GateMan refuses to assist them since it's a natural phenomenone and it's against his tribe's rule to interfere with the law of nature. MegaMan finds out that the tornado was caused by something and not by nature. By cooperating with the Mettols, they are able to defeat the one who created the tornado.

GateMan leads both of them to Navi Graveyard where it says there's a mysterious building that can grant whoever reaches it a treasure that will make them stronger and give him his gate in case of emergency. MegaMan and Lan found themselves lost until GustMan, who performed Full Synchro with Dex, finds the way. Arriving at a pyramid, MegaMan and GustMan struggles and reaches the final room, but GustMan's Full Synchro with Dex accidently disconnected, so MegaMan used the gate to get GustMan out while he remains and finally reaches the room where he is welcomed by PharaohMan. To get the legendary program, PharaohMan makes him fight against four versions of himself. When he is cornered, MegaMan and Lan finally able to perform Perfect Synchro and destroyed all of the four MegaMen and PharaohMan along with the building, allowing their souls to rest.

Grave
Chaud and ProtoMan challenges MegaMan to test how much they have become stronger. Since MegaMan and Lan still have difficulty to perform Perfect Synchro, they cannot use Hub Style and are cornered by ProtoMan's Bloody Quartet. Before their battle could end, AirMan arrives to delete them. In desperate attempt to save MegaMan, Lan and MegaMan perform Perfect Synchro and changes to Hub Style, defeating AirMan. However, MegaMan, unable to control his new power, gone on rampage. With Kei Yuki's help, ProtoMan snapped MegaMan out of his rampage and regain his senses just in time before they are shot with High-Mega Launcher.

Several Dyas later, Lan's class are invited to a luxury cruise ship trip that is actually a trap set by Grave to gain MegaMan's Hub Style power. MegaMan and ProtoMan defeats all of their enemies, but then Grave appears, forcing MegaMan to enter Hub Style, rampaging once again. Only until MegaMan heard PharaohMan's voice he is finally able to control Hub Style. MegaMan is finally confronted by Bass and started their fierce battle after Bass got rid of Grave. Both MegaMan and Bass fought on the same level until Bass enters Hub Style by using his Get Ability program and turn the tide in instant. MegaMan briefly lost contact with Lan since he lost his consciousness due to the burden his body took while performing Perfect Synchro and is beaten to pulp by Bass. In the nick of time, Lan regain consciousness and once again use Hub Style with MegaMan. By focusing all of his remaining power into his finger, MegaMan able to defeat Bass.

Dark Navies
Due to the spreading of power of darkness throughout their world, the Net Navies are materialized in the real world. Mr. Famous brings MegaMan and Lan to a center where he gathers Net Battlers to fight the danger, but all of them are defeated by SandMan who ambushes them. They are saved by ProtoMan and Chaud who have gained Muramasa Style from the King of the Undernet, Serenade, and leads them to a dome where the leaders of the Dark Navis are located. BeastMan attacks them, but easily defeated by ProtoMan and Chaud who decides to face the enemies alone. MegaMan and Lan tried to stop them, but Serenade prevented them from going after Chaud and ProtoMan. Eventually, MegaMan breaks through Serenade's barrier and rendezvous with Chaud and ProtoMan, defeating the enemies together. However, MegaMan still feels uneasy as they faces an unknown being.  The unknown being turns out to be Bass who has became a Dark Navi as Bass GS. Bass intends to destroy the city, but is stopped by MegaMan. Serenade appears to protect him and ProtoMan, but his inability to materialize fully and Bass' newgained power of darkness overpowers Serenade, killing him. MegaMan and ProtoMan continues to fight and finally use the program that Serenade left behind, Double Soul, allowing them to defeat Bass, though Bass survives. Respecting Bass' honor, MegaMan offers him a truce so they can fight again next time without being influenced by anger or hatred. Before Bass could respond, he intercepts an attack by LaserMan aimed at MegaMan. Before being captured by Dark MegaMan, Bass makes MegaMan to promise that he will survive until the day he destroy him. Dark MegaMan reveals that the Dark Navis who they have fought were nothing but normal Navis who borrowed dark power. Introducing themselves as the Darkloids, they declares they will spread the darkness throughout their world and takes Bass with them, much to both MegaMan and Lan's dismay.  Darkloids With the dark power gone, MegaMan returns to Cyberworld as well as the rest of the Navies that materialized in the real world. Their search for the whereabouts of the Darkloids are interrupted by the sudden ambush of SearchMan who demands for MegaMan to come out, accusing him as the one who killed his comrades while in, reality it was actually Dark MegaMan. Switching blows with each other for a moment, SearchMan eventually realized that MegaMan was not the one who killed his comrades. BubbleMan then appears and informs that he knows the whereabouts of Darkloids with his sattelite, but he will only tell them if they pay him 100 million zenny.

Having no other leads, MegaMan and his friends visit BubbleMan to try to negotiate, but BubbleMan won't help unless they pay him high. While MegaMan trying to retrieve his money that was thrown away, Dark MegaMan disguised as MegaMan and attacks BubbleMan and antagonizing GustMan. Using GustMan's anger and hatred, LaserMan changes him into Dark Navi, forcing MegaMan to fight him. However, MegaMan Double Soul with GustMan, forcing Dark MegaMan and LaserMan to retreat. BubbleMan finally agrees to tell him the whereabouts of Darkloids as form of gratitude for being saved.

Finding a dark portal, MegaMan and Lan used Hub Style to enter it and immediately encounter Dark MegaMan. Dark MegaMan summons ShadeMan and use his attack to separate Lan's consciousness from MegaMan and injured him badly. This triggered MegaMan's anger and hatred, giving LaserMan the opportunity to increase Dark MegaMan's power by absoring MegaMan's anger and hatred. SearchMan and his team arrives to help them, but is quickly annihilated, leaving only MegaMan, SearchMan, and Lan surviving the attack. MegaMan and Lan confronts Dark MegaMan with Double Soul SearchMan and try to awake the captured Bass. They are nearly killed until ProtoMan arrives. Unfortunately, MegaMan's brief seemingly death allows Dark MegaMan to absorb Bass and furthered open the dark portal throughout the Cyberworld.

Not believing that Bass disappeared, MegaMan tries to reach out Bass, which he succeeded, returning Dark MegaMan to his original form. Using Double Soul with ProtoMan and SearchMan's help, MegaMan finally deleted Dark MegaMan for good. Their moment of victory didn't last long as more Darkloids appears to fight them who are already out of strength. Fortunately, Colonel and TomahawkMan from Netopia army arrives and destroy the Darkloids along with the Darkspace witht he former's Giga Freeze.

Netopia
Afterwards, MegaMan and ProtoMan are taken for medical check up. In the middle of check up, TomahawkMan arrives with Colonel and MegaMan is ordered to fight TomahawkMan. Using Double Soul with ProtoMan, he easily overpowers TomahawkMan. Much to his shock, Colonel tells him that he will be imprisoned in Netopia prison. ProtoMan helped MegaMan escapes, allowing MegaMan to visit Lan to tell him his situation before escaping to BubbleMan's place. BubbleMan sold MegaMan's location after seeing a flyer with MegaMan's bounty is 100 million zenny, but then tells him to enter the right hole behind the house that's actually a warp hole connected to Schaero where SearchMan is.

Unfortunately, BubbleMan has forgotten that the left hole is actually the one that will lead to Schaero while the right hole is to Netopia. MegaMan spent his times in Netopia disguising himself to prevent capture by the Netopia armies. It was until Lan is in danger he finally revealed himself, something that the Darkloids have expected. To defeat CloudMan, MegaMan Double Soul with TomahawkMan and defeat him. MegaMan is then taken to Netopia base and imprisoned under Colonel's order, making him wondering why Colonel wouldn't trust him. He finally finds out when Colonel attacks CosmoMan, disguised as Bass, revealing that Serenade is his friend and the fact that MegaMan growing close to Bass is what made him unable to trust him. However, MegaMan wins Colonel's trust when MegaMan easily notices that CosmoMan's identity and helps Colonel.

MegaMan and TomahawkMan are assigned to infiltrate Dr. Regal's Darkloid base to investigate. Encountering Nebula Grey, TomahawkMan became Dark Navi, but MegaMan use Double Soul with him to free him. Consequently, this caused all of dark power within TomahawkMan transferred to MegaMan instead, making him a Dark Navi. To free him, Lan transferred himself into Cyberworld. MegaMan nearly attack Lan if only not for Colonel's protection. MegaMan is then captured by Nebula Grey who begin to absorb his power. Encouraged by Lan's words, MegaMan is suppresses his darkness and return to normal.

Nebula Grey
After the incident at Dr. Regal's base, MegaMan is not allowed to be part of the operation against Nebula Grey and instead is taken to hospital for a check up in case he shows any sign of his dark power awakening. Upon hearing that the entire Netopia batalion has been annihilated and little have survived, MegaMan, with the help of GyroMan, ProtoMan, and TomahawkMan goes to where Nebula Grey is who is fighting against Bass and Colonel. MegaMan and the others join forces with Bass and attack together to prevent their attack being absorbed. Nebula Grey easily overpowers them, absorbing ProtoMan, TomahawkMan, and GyroMan, leaving only MegaMan, Colonel, and Bass to fight. Not seeing any other way to win, MegaMan asks for Bass to perform Double Soul with him, which Bass rejected since they are enemies.

MegaMan tries to persuade Bass to fight together so their battle won't end, but Colonel interrupts, warning him that fusing with Bass may make him greater enemy than Nebula Grey for mankind. MegaMan insists that Bass' heart is not only anger and hatred, but Colonel still won't allow him. Promising Lan that he won't give up until the end and then realizes that his friends are still alive, MegaMan rushes to Bass, taking Nebula Grey's attack in his stead, causing him to be near deletion. To save MegaMan's life, Bass absorbed him with his Get Ability Program, fusing them into Bass Cross MegaMan and seemingly defeat Nebula Grey easily.

However, Nebula Grey absorbed CosmoMan and barely survived the attack. Already sensing this, Bass separated MegaMan from him and got bitten by Nebula Grey who slowly regain his power by absorbing Bass. MegaMan, who doesn't has any power left to fight is discouraged, but Bass and Lan encouraged him to not give up. MegaMan use his Double Soul to find a power that will allow him to defeat Nebula Grey. With his newfound power, MegaMan changes into a form of Beast and defeat Nebula Grey.

CyberBeast
After acquiring Beast Out, MegaMan has reoccuring nightmares about him lost control of Beast Out and kill Lan even though Lan assures him that he will stop it with Full Synchro. He is then taken to Underground by a mysterious girl, Iris, who has also summoned several other Navis, including ProtoMan, SearchMan, and TomahawkMan. MegaMan is the only one to object of fighting one another to determine the strongest Navi that will receive the Ultimate program to defeat the CyberBeast, Gregar, while the others agrees. MegaMan is reluctant to fight and tries to persuade the others to no avail.

He then encounters Colonel who challenges him, which MegaMan refused. However, when Colonel intend to shoot Roll as well for trying to defend MegaMan, MegaMan triggers Beast Out, attacking Colonel wildly. CircusMan then appears and traps him within a cage that easily beats the lost control MegaMan. They are interrupted by the arrival of Gregar that sensing part of his power that had been taken by MegaMan and the entire area was destroyed by the CyberBeast before it leaves. MegaMan returned to his senses after Lan use Full Synchro with him and defeat CircusMan. Taking CircusMan's Navi Mark, he passed out and is taken back.

He is asleep for three days and then returns to Underground with Lan to discover that the majority of the other chosen Navis are already defeated by ProtoMan, TomahawkMan, and SearchMan, who all begins to attack him.

Abilities
MegaMan is the only NetNavi who can use various transformation systems like Double Soul, Style Change, Cross System and Beast Out. These draw powers from another NetNavi/Cybeast in order to associate with MegaMan to create a new form. MegaMan can also be customized in many ways, like charge shot (Trans Arm), fighting style (Style Change), special abilites (Navi Customizer), so MegaMan is considered as a "Custom Navi". Due to his many abilities and transformations, MegaMan is also one of the most powerful NetNavis in the series.

Offensive Abilities
 * Mega Buster: This is MegaMan.EXE's standard weapon, like all MegaMen before him. MegaMan can either shoot the buster rapidly, or charge the buster to do more damage. Typically a charged shot deals out 10 times as much damage as an uncharged shot. In Network Transmission, the Buster will attack through a unique formula that takes away a certain amount of health based on an enemy's Max HP, the kind of buster shot being used, and overall upgrades made to the MegaBuster over time. The MegaBuster's power changes depending on the upgrades or NaviCust programs equipped to him, and charged shot changes depending on the Style Change, Double Soul, or Cross System. It is a powerful and effective weapon for MegaMan to utilize.
 * Giga Buster: In the final extra chapter of the Manga, MegaMan uses the new version of his Mega Buster while enter the giga mode (by removing his limiters). It appearance changes greatly, now looking like the barrel of a tank, and its power greatly increases to the same level of power as the Giga Cannon Program Advance.


 * Dark Power: MegaMan is the only Navi who can use Dark Chips without becoming evil, and can even merge them with Double Soul. Usually they permanently reduce his maximum HP by one per battle used. The only way he can't be hurt by one or suffer side effects is by using Double Soul or sacrificing bug frags. Like Beast Out, the player can trigger a berserk state.

Custom Abilities
 * Navi Customizer: Exclusive to the games. Debuting in Battle Network 3, this system allows MegaMan to equip different programs in the form of colored blocks, each of them having a different effect on him. These effects range from upgrading his Buster strength or his battle chip folder capacities, to giving him special abilities, such as generating defensive Reflective Shields or surviving fatal blows with 1 hp of auxiliary energy. However, the Customizer has its own rules, and breaking these will result in bugs on MegaMan.


 * Style Change: Debuting in Battle Network 2, this allows MegaMan to change his elemental alignment and get upgraded power depending on the change. There are twenty-eight different customized styles (four elements and seven Styles).


 * Trans Arm: Introduced in Rockman.EXE Legend of Network, the Trans Arm is similar to the Double Soul, but only changes MegaMan's charge shot and color.

Transformation Abilities
 * Cross Fusion: Exclusive to the anime, by the use of a special Battle Chip inside a Dimensional Area, MegaMan can synchronize with Lan and fight in the real world. However, if not in full sync, the Cross Fusion can deteriorate.


 * Double Soul: Also known as Soul Unison, by resonating with another Navi's soul, MegaMan can gain the abilities of the Navi along with additional powers. In both Mega Man Battle Network 4 and 5, MegaMan gains six Souls, each of them varying depending on the game version. In the anime, the side effects of Cross Fusion removed the use of the Style Change and Double Soul was acquired as a replacement. A dark form of it is known as Chaos Unison.


 * Cross MegaMan: This is the prototype/alternate/advanced version of Cross System exclusive to Mega Man Battle Network 5. It provided an alternate base form for MegaMan with several Navi Customizer programs already installed, as well as an altered charged shot. However, it is much more potent than the Double Soul and Cross Systems due to no elemental weakness, permanent transformation and a lot of special abilities.


 * Cross System: This is similar to Double Soul, but with certain differences. Exclusive to Mega Man Battle Network 6, this becomes his new means of transformation, combining the abilities of Double Souls with the long duration of Styles. MegaMan gains 5 Crosses per game in Battle Network 6, each of them varying depending on the game version.


 * Beast Out: There are two different Beast Outs, Falzar and Gregar, and the one you get is dependent on the version played. It can be activated at any time between turns. It expires after three turns, and if Beast Out is used again immediately afterwards, MegaMan enters Beast Over, and goes berserk. Beast Out can combine with Crosses to form Cross Beasts, each with their own chip charge attack.

Special Abilities
 * Bug: Though not an actual ability, bugs are glitches in MegaMan, but only he can utilize and use its power. These glitches may cause a variety of side-effects during a battle.


 * Hub.BAT/Hub Batch: The Hub.BAT is a program that when equipped into MegaMan's system completes Hub's DNA within him. It gives MegaMan all powers from style changes in Battle Network 2, and all NaviCust programs installed with a halved-HP bug in Battle Network 3. In Battle Network 6, it appears as a Giga Chip and with the same effects as in Battle Network 3, but with the exclusion of the HP Bug.


 * e-Reader Cards: (Japanese only): Players can insert e-Reader Cards to customize Rockman in special ways. These cards caused various effects as, such as Base HP, Abilities, Buster Changes, Charge Shot Modifications, B+ Back Abilities. There are even Item Cards which can give out sets of Battle Chips, Sub Chips, BugFrags, Zenny, and even Navi Customizer Programs (only introduced in Rockman.EXE 6 Modification Card Part 1 & Rockman.EXE 6 Modification Card Part 2). They could also cause negative effects ("Bugs") to occur, such as causing Rockman to lose health and move the wrong way, or causing the player to be unable to control him.

As a boss
In the game series, there are several times where MegaMan goes berserk, and Lan must fight against him using another Navi. Additionally, many villains have tried to create mirror images of MegaMan, but fail because they copied him using a certain power (namely Dark Power and Beast Out).

Dark MegaMan/MegaMan DS
The boss pattern of MegaMan DS (MegaMan Dark Soul) is an almost complete mirror of that of the player's. He has exactly the same Max HP at the start of the battle and uses Battle Chips, preferring those in the player's folder. A good way to counter this is by putting several chips together that would be needed for a Program Advance or special combo (e.g. Sanctuary and Holy Dream), as MegaMan DS has a tendency to use chips at random and can't use PA's, but on some rare occasion, Dark MegaMan can use LifeSword. In Mega Man Battle Network 5, when MegaMan uses the Dark Chip DarkInvis, MegaMan will enter a state just like MegaMan DS. Also in Mega Man Battle Network 5, if MegaMan uses a Chaos Soul and fails to use the charge attack correctly, MegaMan DS will form and try to kill MegaMan until the viruses are deleted. This MegaMan DS has no HP, but will dissipate after a long period.

It's worth noting that Dark MegaMan only appears in Mega Man Battle Network 5, and that there is a difference between him and MegaMan DS. Whereas Dark MegaMan is MegaMan overwhelmed and transformed by Dark Power, MegaMan DS is the embodiment of MegaMan's evil but was removed after then ending of Battle Network 5.

GBeast and FBeast
GBeast (Gビースト) and FBeast (Fビースト) are bosses from Mega Man Battle Network 6, each appearing in a different version. Contrary to Dark MegaMan, they have more of a fixed battle pattern. When MegaMan is consumed by the Cybeast Gregar or Falzar, Lan must use one of his Link Navi partners to fight against him. Later, a copy made of data bits appears in the Underground, and MegaMan has to fight against it and Bass.

GBeast
GBeast is a boss from Mega Man Battle Network 6 Cybeast Gregar. In this form, he uses a rapid fire blaster.

Attacks:
 * Thunder: GBeast Breath Thunder Chips nad Launch's them in a Slow Homing Thunder Ball That follow the player for 5 seconds.


 * Gregar Claw: GBeast homes in on the player and slashes twice, first in a LongSword fashion and second in a WideSword fashion.(in Double Beast Gregar will use Wide Blade while Falzar will use Long Blade)


 * Stun Claw/Gregar Buster Combo: GBeast uses a stunning LongSwordBlade slash, and then fires with a Multi-hit Gregar Blaster.


 * Gregar Breath: GBeast uses a Gregar Breath which has 2nd Big Hook & Sword chip range.

FBeast
FBeast is a boss from Mega Man Battle Network 6 Cybeast Falzar. In this form, MegaMan can rapidly shoot metal feathers on his row and two ahead on the rows he is.

Attacks:
 * Aqua Needle: He launches needles at the playable character's field. Dodging is easy; simply move away from the glowing panels.


 * Boomer: He summons one boomerang to attack the top, bottom and the last panel of the center row like the battle chip.


 * Falzar Claw/Buster Combo: He jumps in front of the playable character and slashes twice. If stunned after the second slash, he will fire a total of 30 sharp feathers at the opponent. This can also be done if the stun takes effect after the first slash as well.


 * Falzar Storm: He blasts wind at the center row and the last panel of the top and bottom row.

Trivia

 * Normally, in both the games and the anime, MegaMan is often the character who breaks the fourth wall (sends a humorous message or joke straight to the audience) normally in the intro or during a lull in the plot.


 * This is the first Mega Man so far to have an actual logo. Mega Man from the Mega Man Star Force series later bears his own logo.


 * As default, MegaMan.EXE doesn't have a pre-installed shield like the Star Force Mega Man. That's why all attacks of all bosses from the Battle Network series don't affect all of MegaMan.EXE's panels. For an example, MegaMan EM can block Crimson Dragon's laser attack with his shield, but MegaMan.EXE (if he was there) can't do that. Another example, in Battle Network 5, Bass' Darkness Overload attack doesn't damage all of MegaMan's panels, but only a 2x3 area so that MegaMan.EXE can dodge it without a shield.


 * MegaMan's eyes are green, but in the first three Mega Man Battle Network games his mugshot shows him with blue eyes. It was fixed in later games.


 * In Mega Man Battle Network 6, the sprite used for walking in the cyberworld make his eyes look blue. However, his battle sprite has brown eyes, but his mugshot shows than his eyes are green which is their true color.


 * He has unused overworld sprites in Mega Man Star Force 2 and 3.
 * MegaMan.EXE, however, makes a cameo appearance in the first Mega Man Star Force game in one of the side quests. If the player completed the side quest and returned the "SciLab" data for MegaMan.EXE, he will make a short appearance from the portal and gives Geo the "BNBlaster", or "Battle Network Blaster".


 * Mega Man Star Force always keeps the weapon "BNBlaster" in the series, players can get the advanced version, "BNBlaster-EX" with a Cipher Code in Mega Man Star Force 3.


 * Geo Stelar, the main character in the Mega Man Star Force series shares many traits with MegaMan.EXE such as his fear of ghosts, and both being more level-headed than their respective partners.
 * In Mega Man Star Force 2, Lan's diary entries can be obtained through side quests. One entry reveals that Patch, Lan's son from the epilogue of Mega Man Battle Network 6, had his own NetNavi: MegaMan Junior, a program combining the best qualities of MegaMan and Roll, making Junior the son of both Navis.
 * He is the only Mega Man incarnation that enjoys fighting, a good example is his willingness to take part in net battle tournaments.
 * All other Mega Men are considered pacifists.
 * According to concept art, Megaman has brown hair, yet when his helmet is on, it's black, suggesting the back is actually part of the helmet, or was a glitch in Megaman's programing.
 * In the anime, Megaman doesn't understand Lan's fascination with food.
