"...I just... follow Chaud's orders..."
—ProtoMan.EXE, Mega Man Battle Network 2

ProtoMan.EXE, known as Blues.EXE in Japan, is a NetNavi from the Mega Man Battle Network series operated by the ace NetBattler Eugene Chaud and rival of MegaMan. ProtoMan specializes in swords and uses many sword-type Battle Chips. ProtoMan appears in many stories of the series, and is playable in Mega Man Battle Network 5, Mega Man Battle Chip Challenge, Rockman.EXE 4.5 Real Operation, Mega Man Battle Network 6 (using the Beast Link Gate), and Rockman.EXE Operate Shooting Star (in the Rockman Star Colosseum mode).


ProtoMan is the elite NetNavi of Eugene Chaud (Chaud Blaze in the English anime, Enzan Ijuuin in Japan). His Navi mark, a circle split with a thunderbolt pattern into two black and white sections, can be seen on ProtoMan's chest and gloves, as well as, in the games but not in the anime, on the back of Chaud's vest. Unlike his original counterpart, he normally uses a sword weapon instead of a buster, although he does use a shield reminiscent of the original Proto Man's, and does have a buster weapon when the player activates the Double Hero Program Advance and when he's player-controlled. ProtoMan stands at 161 virtual centimeters (roughly 5'3").


ProtoMan's most defining character trait is that he is completely loyal to his NetOp, Chaud, and will follow any order given to him. He is also willing to sacrifice himself for Chaud. The two work together very well since they practice so many hours a day. In the anime, it is shown that ProtoMan was Chaud's best friend as a child when he received him as a gift. ProtoMan is also serious and doesn't talk much, but not to the point of being socially isolated like his NetOp. In the manga, ProtoMan is quicker to anger whenever MegaMan acts stupid, resulting with him punching him and getting into a fight with him in a comical manner, making it one of the running gags in the series. In addition, he is also more open about his feelings and his friendship with MegaMan is shown clearer.

Game History

ProtoMan, as a Navi for an Official NetBattler, is extremely well-trained by Chaud, who actually created ProtoMan himself. In Mega Man Battle Network, ProtoMan fought alone and won every fight without Chaud operating him. This streak was considered to be a force to be reckoned with to those who knew of them until he saw his downfall at the hands of MegaMan during the ElecMan scenario. Defeated, ProtoMan asked MegaMan how he fights so well and his connection to his operator Lan. When MegaMan explained to ProtoMan what that connection was, this made ProtoMan and Chaud rethink the way they operate. With ProtoMan's great fighting skills and Chaud's talent in NetBattling, this team is one of the few who can match Lan and MegaMan in strength. It is revealed in Mega Man Battle Network 3 that Chaud spends at least 10 hours a day training to uphold his skills.

In Mega Man Network Transmission, ProtoMan operates in the same role as in the previous game, Mega Man Battle Network. He and Chaud tell MegaMan and Lan to back off and let the police deal with these matters. MegaMan later finds ProtoMan in Old Area, near deletion at the hands of SwordMan. ProtoMan then sees MegaMan again after MegaMan defeats Zero, at which time ProtoMan is called upon to finish Zero. What happens to Zero after that depends on several factors. ProtoMan can be battled at the entrance to the Undernet upon the player receiving the AuthCode. ProtoMan assists MegaMan through Lan's and MegaMan's adventure at various times.

Throughout the series, Chaud has operated him to defeat Net criminals as an Official NetBattler. ProtoMan has gained a fearsome reputation and deletes NetNavis in the nick of time when MegaMan can't. He can be battled in every game except for the Team Colonel version of Mega Man Battle Network 5 and in Mega Man Battle Network 4 Red Sun.

In Mega Man Battle Network 6, he has an extra form which can be unlocked after completing all requests which is super powered, making him the only non-villainous NetNavi in Battle Network 6 to have more than three forms (The WWW Navis all have a secret "RV" form).

Anime History

ProtomanEXE MegamanNTWarrior S1EP25

ProtoMan.EXE in MegaMan NT Warrior.

ProtoMan doesn't change much from his game counterpart in MegaMan NT Warrior. He is still loyal to Chaud and extremely powerful, deleting his enemies in seconds. ProtoMan and Chaud are Lan and MegaMan's rivals in the first part of the anime.

MegaMan NT Warrior

N1 Grand Prix Arc

ProtoMan first appeared when MegaMan was about to be deleted by MagicMan, attacking and defeating MagicMan with one strike, and began a rivalry with Lan and MegaMan, though Chaud and ProtoMan believed that their rivals were inferior. Both Chaud and ProtoMan enter the N1 Grand Prix and defeat their opponents easily, winning in mere seconds, which were record times to everyone that had witnessed it.

During one night, Lan challenged Chaud to a NetBattle, due to an earlier insult to both Yai and Lan at a restaurant. When the battle began, ProtoMan easily had the upper hand on MegaMan with a simple CyberSword, and his speed being described as being twice as fast as SkullMan. As they battled on, a horde of viruses attacked, sent by BombMan and StoneMan to delete the two. ProtoMan handled himself well against the virus attack, though MegaMan was slowly being pushed back and overwhelmed. Just when MegaMan was about to be deleted, Chaud and ProtoMan witnessed Lan using the Long Sword Battle Chip, unknowingly triggering a Program Advance, which weakened the giant virus before fading away, and ProtoMan deleted the virus afterwards.

Later on, when ProtoMan faced ElecMan in the tournament, Count Zap cheated by having the battle screen for everyone but his own malfunction, preventing the battle from being seen by anyone else, which gave ElecMan the advantage. However, that didn't phase ProtoMan or Chaud at all, who instead used a defense chip to block an attack, and then utilizing the Program Advance themselves, having mastered the technique already, unlike Lan and MegaMan who were still training. The attack easily defeated ElecMan, leaving on pieces of him in the battle, though ElecMan had survived and had managed to log out.

They have to team up for the next round with ShiningMan and his NetOp. In the ensuing battle, ProtoMan deletes his enemies and ShiningMan. They are then forced to team up with Lan and MegaMan against StoneMan and BombMan. ProtoMan at first made no move when the battle began, and still didn't move when MegaMan was being beaten. However, when he finally moved, ProtoMan punched MegaMan in the stomach and threw him back to prevent him from interfering in the match, as he had stated that he didn't need any help, and that MegaMan would only get in the way. ProtoMan made his attack, and easily avoided the attacks sent to him, eventually defeating BombMan easily with a Blade Cyclone attack pattern, which Chaud stated to be unrivaled.

He later used it again on StoneMan after it was thought that MegaMan had been deleted after the latter had pierced StoneMan's eye, to which StoneMan used Quake to crush MegaMan. The attack left StoneMan in pieces, but he soon regenerated with a special program inside him, which fully restored the Solo NetNavi to his prime state. ProtoMan slowly began to lose the Netbattle, mostly due to the fact that Chaud was missing a Battle Chip for the Program Advance. However, MegaMan soon arrived, revealing to have survived and had simply lost connection due to interference from the Quake. MegaMan then uses his Program Advance and once more left StoneMan in pieces, but right before the regenerative program began to try and rebuild StoneMan, ProtoMan destroyed it, defeating StoneMan for good. It was then just MegaMan and ProtoMan for the final match.

On the day of the finals, ProtoMan had been having a simulation battle against MegaMan to see how the chances for victory was, showing to be 97.4%, which made Chaud wonder how that was possible believing that it should have been 100%. ProtoMan and Chaud begin their Netbattle against Lan and MegaMan in the finals, but surprisingly, MegaMan had been holding his own, and even pushed ProtoMan back, as noted that ProtoMan had began to get exhausted. Both Chaud and ProtoMan realize that Lan and MegaMan's strength lies in the friendship they have with each other and the people that support them, but even then, Chaud and ProtoMan refused to give in. After a long battle, with the two NetNavis using their Program Advance, an attack that seemed to shake the entire island from the clash, but in the end, Chaud and ProtoMan emerge victorious, though ProtoMan had gained a newfound respect for MegaMan's skill, never having faced an opponent like him before.

However, their battle had awakened PharaohMan, who fired an attack meant for ProtoMan, but MegaMan pushes ProtoMan out of the way, and is deleted in the process, shocking ProtoMan and everyone else that had witnessed it. ProtoMan demanded who the atacker was, and saw PharaohMan, who stated himself to be the most powerful, and was about to delete ProtoMan, but was saved when Chaud logged him out, as the N1 dome sank.

Later, Chaud and ProtoMan went to retrieve MegaMan, who had been restored with the help of Lan, his friends, and Lan's father, but MegaMan had fallen into a chasm of lava underground, and ProtoMan managed to save him before MegaMan was deleted once more. Now having repaid his debt to MegaMan, he went to go confront PharaohMan alone, but despite his efforts, he was helpless against the Navi, but before ProtoMan was about to be deleted, MegaMan had awakened just in time and intervened, saving ProtoMan. The two teamed up and used a Double Program Advance to delete PharaohMan, though the attack had only wounded him and sent him crashing back, but was captured just then, with MegaMan following after.

After that battle, ProtoMan and MegaMan became friends throughout the anime, though still maintained a rivalry with each other.

Grave (Gospel) Arc

ProtoMan would come from time to time, once having a race with MegaMan and several others, using a motorcycle developed by Chaud's company. The two were fierce and seemed to have finished the race at the same time, but when ProtoMan raised his hand in the air, everyone believing that he was declaring himself the winner, ProtoMan then pointed to MegaMan, stating that he had won instead. But then the photo revealed that it was Rush that had one, much to everyone's surprise, and ProtoMan sweatdropping from slight embarrassment.

When the Grave Virus Beast had began the rampage throughout the Net, sent by Grave, the beast was consuming Navis in alleys, one of the Navis happened to work at Chaud's company, which prompted for ProtoMan to investigate. When ProtoMan and MegaMan fought the Virus Beast the first time when it attacked the Colosseum, they tried to fight it, but they were easily defeated with one strike, much to the shock of Chaud. Had it not been for Bass mysteriously appearing, they would have been deleted.

MegaMan and ProtoMan had a conversation on top of a building, where they had a friendly fist fight, where they talked to each other and promised that after this battle was over, they would have another NetBattle to settle the score. However, that promise wasn't able to be realized, as when Grave Virus Beast later attacked the Netopia Net, ProtoMan faced it, but even when he had used the Program Advance, the attack didn't even make a dent on the Virus Beast. Chaud told ProtoMan that he would log him out, but ProtoMan insisted on staying when he had seen a child NetNavi about to be deleted, and rescued her, but right as they were able to log out, the Grave Virus Beast caught them, destroying ProtoMan's motorcycle, and ProtoMan threw the child Navi back which allowed her to log out, but ProtoMan was caught in the jaws of the beast, and despite Chaud's attempts to log ProtoMan out, he couldn't, and Chaud could only watch as ProtoMan was deleted and absorbed by the beast. When MegaMan heard the news, he was deeply upset, remembering their promise.

After MegaMan BugStyle awakened several days later, due to MegaMan's Ultimate Program reacting to try and repair itself due to the bug that had invaded MegaMan after an encounter with Bass, the Grave Virus Beast tried to absorb MegaMan, but MegaMan's Ultimate ended up overwhelming the Grave Virus Beast despite it having both PharaohMan's and ProtoMan's Ultimate Programs in it. After MegaMan absorbed the entire network, but later ended up rebuilding everything, ProtoMan was revived, along with everyone else that had been absorbed by the beast.

ProtoMan would once face MegaMan in a NetBattle, and used the Program Advance on him, but MegaMan had managed to cut through it with a CyberSword, surprising both Chaud and ProtoMan. ProtoMan still managed to fight against MegaMan, but the battle would be cut short due to Chaud needing to attend some business. later on, Chaud used ProtoMan to perform a Program Advance to try and shape a special program, but the power was uncontrolled, and resulted in a failure, despite seeming to be perfectly made.

When the program was stolen, and the original data was being attacked, ProtoMan was attempting to stop it, deleting the viruses, until he was attacked by DrillMan.EXE. Despite the powerful strikes ProtoMan did, even using a Program Advance, DrillMan wasn't harmed at all, and ProtoMan was facing a losing battle. However, after Chaud understood what it meant to have a more controlled power, he had ProtoMan use a normal CyberSword and focus the power into one attack, which allowed ProtoMan to cut DrillMan in two, deleting him.

Afterwards, ProtoMan had another NetBattle against MegaMan.

MegaMan NT Warrior Axess

ProtoMan appeared when Lan was in museum that was being attacked by SavageMan.EXE, helping MegaMan from the viruses to give MegaMan a chance to Cross Fuse with Lan when SavageMan appeared into the real world using the Dimensional Area.

The next time he's seen, Chaud was attempting to locate a Dark Chip facility, after Lan had managed to find a warehouse that had shipments ready to be sent out. When Chaud and Lan were talking about it, they saw Ms. Yuri, though she was disguised as Ms. Mari, he immediately suspected that she was an impostor. He had sent ProtoMan to tail her car, which ended up leading Chaud to the real Dark Chip factory, while Lan had been sent to an abandoned facility to ambush him. However, by the time Chaud arrived, Ms. Yuri already told him that the facility was no use anymore, and had it destroyed, though Chaud managed to escape.

Chaud had then hurried to where Lan was being attacked by DesertMan.EXE and had performed a Cross Fusion with ProtoMan, saving Lan when he was about to be killed after being defeated by the Darkloid. After figuring out that DesertMan they had been fighting was a fake, CF ProtoMan pierced a separate pile of sand, after figuring out that it was the real DesertMan due to the Darkloid lowering his guard.

It turned out that Chaud had received a Synchro Chip a while ago, and when he cross fused with ProtoMan, the synchronization between the two was even greater than that of Lan and MegaMan's, which made Lan upset after he found out from his dad.During the Axess season, Chaud gains the ability to perform Cross Fusion with ProtoMan. Lan and Chaud go through the first half of Axess using the Cross Fusion to defeat the Darkloids. Later, when ShadeMan was trying to redeem himself to Dr. Regal and the two find themselves unable to defeat ShadeMan, Chaud reluctantly provides his Navi with a Dark Chip. In doing so, he released the dark soul in ProtoMan, which allowed him to escape. ProtoMan would later return as Dark ProtoMan, a Darkloid completely absorbed by the Dark Aura due to the tampering of LaserMan. As Axess reached its finale, Chaud was able to rescue his friend's spirit, returning him to normal by using Cross Fusion with him, confronting him within the confines of his heart.

Gospel Arc

ProtoMan challenges MegaMan to test how strong he has become. At first, both are on equal strength until ProtoMan uses Bloody Quartet. Their fight, however, was interrupted by AirMan.EXE who threatens to delete MegaMan if ProtoMan make a move.

However, their shopping plan was ruined when all Navis recognizes MegaMan and asks for signs and handshake, forcing them to run away. They ends up falling into a panel out and met a man in cloak who threatens to detonate bombs he had prepared. ProtoMan attacks him, but his attack was blocked by a barrier. The bombs turns out only to be toys and the man is revealed to be human, introducing himself as Mr. Famous who immediately gave them 30 point each.

Having heard of Mr. Famous' reputation, Chaud and ProtoMan decides to cancel their plan today to train. To become stronger, Chaud and ProtoMan goes to Undernet, fighting all the Navis and viruses there, eventually meeting the king of Undernet, Serenade. Serenade offers him a power to fight incoming obstacles, but warns him that accepting the power will force him to continue fighting no matter how terrible his wounds or how horrible his pain are until his life end. Recounting of how he had always ended up leaving MegaMan to fight alone, ProtoMan and Chaud resolves that they won't run anymore no matter who their enemies are. Accepting their resolve, Serenade bestows ProtoMan with Muramasa blade.

ProtoMan and Chaud then saves MegaMan and the others who were on verge of defeat by DesertMan by using Muramasa Style. ProtoMan and Chaud then tells Lan and MegaMan to leave everything to them or else they will die. ProtoMan easily defeat BeastMan and go alone to where the source of the dark power emanates. There, ProtoMan is attacked by DarkMan, DrillMan, and PlantMan. Heavily injured, the Muramasa blade that ProtoMan use only becoming stronger.

ProtoMan tries to fight again, insisting for MegaMan not to interfere. Having enough with ProtoMan's persistance, MegaMan helps him to realize that they are friends. Together, they defeated DarkMan, PlantMan, and DrillMan.

ProtoMan was ready to destroy the source of the dark power, but from the source, Bass comes out, much to their shock since he was supposed to be deleted. DarkMan reveals that the dark power has revived Bass as Bass GS. Bass unleashes his wave, destroying the whole island in instant. Injured from protecting MegaMan, ProtoMan gave MegaMan part of his power and tell him to go after Bass.

After recovering from his injury, ProtoMan finds MegaMan overpowered by Bass and tried to catch him when bass threw him down. Unable to make it in time, Serenade appears and save MegaMan instead. Serenade protects the two of them due to his promise with Mr. Famous, but got captured by Bass who started to absorb his power.

With their feelings united, ProtoMan and MegaMan performs Double Soul, turning MegaMan into MegaMan Proto Soul while ProtoMan, as the result of giving nearly all of his data to MegaMan, went unconscious on the verge of deletion.

After Bass was defeated, ProtoMan and Chaud returned to normal, glad that everything was over. This didn't last long because Bass revealed himself to be alive. ProtoMan intended to defeat him for good, but Chaud tells him to wait and watch MegaMan offering Bass a chance to start over. However, they are then attacked by MegaMan DS and LaserMan, introducing themselves as Darkloids and takes Bass with them.

Darkloid Arc

When the Dark Hole begins to engulf the Cyber World, ProtoMan was about to jack out with other Navis, but spotted injured SearchMan and tries to help him, but got sucked into the Dark Hole with him. Getting sucked into the Dark Hole transported him to the same place as MegaMan, and saves him just before he is deleted. He then fights LaserMan, but was no match for him. Seeing MegaMan injured from MegaMan DS' attack, ProtoMan tells him to Double Soul, but his foot was shot by LaserMan. Before LaserMan's beam could attack, SearchMan shot him with Data Recovery delivered by BubbleMan, healing ProtoMan and restoring his connection with Chaud. With Muramasa sword, ProtoMan defeats LaserMan. ProtoMan then gives his power to MegaMan, performing Double Soul until MegaMan DS is defeated.

After defeating MegaMan DS, other Darkloids started to appear. ProtoMan and SearchMan were ready to fight again, but Colonel and TomahawkMan arrived, saving them. ProtoMan and MegaMan are taken to Medical center for maintenance, but are interrupted by TomahawkMan and Colonel. After MegaMan is ordered to be imprisoned, ProtoMan helps him escape.

In the battle against Nebula Grey, ProtoMan joins the fight with MegaMan, GyroMan, and TomahawkMan. However, he is absorbed by Nebula Grey along with GyroMan and TomahawkMan while defending MegaMan before they can perform Double Soul. The three of them are then used by CosmoMan to threaten Bass Cross MegaMan from dealing a finishing blow towards the weakening Nebula Grey, but they are rescued.

Cybeast Arc

ProtoMan is one of Navis chosen by Iris to participate in battle that deciding who is the strongest Navi worthy to earn the legendary program to defeat the Cybeast. ProtoMan, along with other Navis, are willing to fight one another for exception of MegaMan, and refuses MegaMan's idea to think over. While MegaMan is absence for three days due to overuse of Beast Out, ProtoMan, TomahawkMan, and SearchMan already defeated the majority of Navis participating in the battle. The three of them attacks MegaMan who at first refuse to fight, until he determined that he cannot lose, defeating the three of them with ease with Beast Out.

Another Cybeast, Falzar arrives, sensing Gregar's power within MegaMan and attacks. Much to MegaMan's shock, ProtoMan, SearchMan, and TomahawkMan protects him.


ProtoMan is one of the strongest NetNavis in the Mega Man Battle Network games. He has excellent potential with his sword and shield. When fought by the player, his attacks and behavior differ from game to game. In the anime, he is one of the few NetNavis that possesses an Ultimate Program.


ProtoMan's Emblem

  • Proto Shield - Surprise Sword: ProtoMan's basic defense. At higher power levels, as ProtoMan pauses between his own attacks, most incoming strikes are blocked by his ProtoShield. He's less scrutinizing in later games, taking hits more often. In Battle Network 6, if he's struck when shielding, he will immediately speed towards the opponent and slash them (Surprise Sword). A good way to overcome this defense in later games is to use a multi-hit chip, as he'll walk right into the attack. In BN5 - TP, this is replaced with Reflect, usable by the player by pressing Left and B simultaneously.
  • Sonic Sword: One of ProtoMan's rudimentary fighting attacks. He randomly shifts between the top and bottom rows, swinging a three panel wide sword attack that flies to the other end of the stage. He will sometimes strike consecutively, cycling between the top and bottom column, making the attack hard to dodge. He stops using this attack in later games.
  • Step Sword: Another of ProtoMan's basic skills. In previous games, he only used this when shot at, bringing up his shield. He'd then teleport in front, and use a Wide Sword attack. He later begins using this over the Sonic Sword completely. If MegaMan is on the front rows, ProtoMan may also teleport behind and attack. This is present in later games. In the fifth game, where ProtoMan is playable, Step Sword is a chip exclusive to him, and works like the previous games' Step Sword chips, moving 2 panels ahead and using a Wide Sword.
  • Fighter Sword: Used in later games, ProtoMan stands in the front row of his panels, and swings a Fighter Sword, hitting three panels ahead to the back row.
  • Cross Sword: In Battle Network 6, he is capable of attacking in a + formation.
  • Trance Move: Replacing his Delta Ray Edge in Battle Network 6, ProtoMan will zip around with the player's position as the center, first diagonally from the top left panel then the bottom left panel, then back and forth the middle row, hitting him several times, dealing massive damage. This attack cannot be executed if the player steps on the bottom or the top row when ProtoMan is about to strike (after the ding sound).
  • Delta Ray Edge: One of ProtoMan's strongest attacks and techniques. This attack is heralded by a sudden flash, and then ProtoMan loops the area his opponent was last on, striking three times with a Wide Sword-ranged attack that cripples and paralyzes the opponent. Once all three strikes are executed, ProtoMan reappears in front of the enemy, his opponent ringed in the shining image of a triangle (technically, the three strikes do not all have to connect to leave the triangle-afterimage). The Delta Ray Edge Giga Chip is available in Mega Man Battle Network 3 to 6. This attack, both by ProtoMan and the Chip can only be used properly when the opponent is in the middle row, in the front or center panel, as the attack requires an open panel behind the target. This attack is greatly different in the anime, with ProtoMan drawing a triangle with his sword and launching it towards his opponent.
  • Blade Cyclone: An anime only attack that has no name, but the technique involved ProtoMan having two sword-type Battle Chips, and then spinning incredibly fast that it produces a crimson red cyclone, that when it engulfs an opponent, they are slashed countless times faster than they can react. Chaud stated when he first used it that this attack pattern was unrivaled. This same technique has also been used to create diversions, and drilling through the ground.

ProtoMan gains some new moves as ProtoMan DS/Dark ProtoMan. Note that he can't use Delta Ray at all in this form.

  • Shadow Shield: A dark silhouette of ProtoMan replaces his shield to block attacks. Note that with any attack involving a clone, the clone will block all attacks like a regular obstacle.
  • Dark Sword: ProtoMan's normal sword has been replaced with a Dark Sword, which he uses in most of his attacks.
  • Shadow Slice: A dark silhouette appears and uses a Fighter Sword. ProtoMan still moves while the clone attacks.
  • Dark Step Sword: ProtoMan disappears. A clone will attempt to slash a Dark Sword behind the player. ProtoMan will then reappear and then use a Dark Sword in a similar fashion to his normal Step Sword.

In the Mega Man NT Warrior manga, ProtoMan is given the power to Style Change by Serenade.

  • Muramasa Style: ProtoMan wields the legendary blade Muramasa and wears a new outfit. The more damage ProtoMan takes in this form the more powerful his sword becomes. Originally, this form could only be used against Dark Soul Navis and Darkloids, but later ProtoMan had the sword reforged, so he could use it against anyone in order to use it against MegaMan.

Battle Chips

ProtoMan (Blues in Japan) is a Navi Chip present in most games from the series. It summons ProtoMan, who will move to the closest enemy and attack with his sword.

Hawk Cut, known as Hayabusa Giri (ハヤブサギリ) in Japan, is a Battle Chip from Mega Man Battle Network 4 that cuts 3 vertical squares then 2 horizontal squares. The Katana Battle Chip from the fifth game is similar to Hawk Cut.

Delta Ray Edge (デルタレイエッジ) is a Giga Chip that summons ProtoMan to perform his Delta Ray Edge attack. It is available in Mega Man Battle Network 3 Blue, Mega Man Battle Network 4 Blue Moon, Mega Man Battle Network 5 Team ProtoMan, and Mega Man Battle Network 6 Cybeast Gregar.

Leaders Raid (リーダーズレイド) is a Battle Chip from Mega Man Battle Network 5 Double Team DS that summons both ProtoMan and Colonel. ProtoMan moves to the closest enemy to attack with a wide slash and is followed by Colonel attacking with Cross Divide.

  • Using the Beast Link Gate or cheats in Mega Man Battle Network 6 allows the player to play as ProtoMan as a Link Navi.
  • ProtoMan's emblem is similar to the Yin-Yang symbol, one side of cold indifference and the other of striking kindness.
  • According to UDON's English translation of Rockman.EXE Official Complete Works, early concepts of ProtoMan depict him with a scarf like his classic counterpart, but there was a rule in which it was forbidden to give Navi characters any form of cloth to "ensure [they] gave off a cyber vibe." Hence, ProtoMan was given long hair to make up for the missing scarf (this rule, however, would later be broken by a few Navis, first being Bass.EXE).
  • While most of his appearance and personality are based on the classic Proto Man, some aspects of him were distinctly inspired by Zero from the Mega Man X series, his sword and long hair being the most obvious examples.
  • Although ProtoMan.EXE's English name is derived from his classic series counterpart, it should be noted that it makes no sense from an in-universe perspective, as he is not a prototype of anything.
  • One issue of the MegaMan NT Warrior manga featured a potential character who would serve as a love interest to ProtoMan. Playing off ProtoMan's Japanese name, Blues, the new female character was named Rhythm.
  • Protoman's Seiyuu also did Teru Mikami from Death Note and both have to do with deleting and preserving their society.
  • Since Protoman's classic counterpart is influenced by Char Aznable, one of Char's expy Gaelio Baudain/Vidar has the same Seiyuu as Protoman.EXE. Both are policeman who serve their government only to end up supposedly "killed" but came back as another incarnation. Also both disguise themselves to secretly get close to their enemy and forming a rivalry with a formidable enemy who has extreme intentions. Also both have short term rivalry with the main character.
