    open/close all folders 

    Raika and SearchMan.EXE 

Raika voiced by: Hiro Yuki (JP), Matt Smith (EN)

SearchMan voiced by: Jun Fukuyama (JP), Brian Dobson (EN)
A military commander from the cold nation of Sharo, he is the operator of the sniper SearchMan.EXE. Their first game appearance is as one of the possible tournament opponents in Red Sun and one of the few characters to actually do something about Nebula. A few months after the events of 4, they joined Team ProtoMan as the intel of the group. They usually only cared about achieving their objectives during dangerous missions, but in the anime, they eventually warm up to the main casts' friendly personalities.

  • A Day in the Limelight:
    • Axess episode 35: They team up with Raoul and ThunderMan to fight FridgeMan, BrightMan, SwordMan, and StarMan.
    • Stream episode 26: Shared with Pride while fighting Asteroid AirMan.
    • Beast episode 17: Shared with Dingo and TomahawkMan as they fight Beyonard Narcy and VideoMan.
    • Beast + episode 22: They battle against phantom navis impersonating MegaMan and ProtoMan.
  • Ascended Extra: He and SearchMan become main characters in the anime during Beast.
  • Attack Drone: SearchMan can control mini satellites that can fire laser beams.
  • Bodyguard Crush: In the anime, Raika is given some Ship Tease with Princess Pride, but nothing comes out of it.
  • Brainwashed and Crazy: SearchMan gets possessed by Reverse in Legend of Network.
  • Breakout Character: Is given a much larger role in the later seasons, basically becoming the tertiary protagonist after Lan and Chaud.
  • Chest Insignia: A crosshair.
  • Cold Sniper: He and SearchMan are quick to delete any innocent Navis corrupted by Dark Chips since they believe its the only way to save them and its most definitely the only way to prevent more damage.
  • Crosshair Aware: SearchMan is a Cursor Navi. He is the one responsible for scoping all over MegaMan in BN4's Undernet to test him and Lan.
  • Expy: A haughty young high-ranking official who looks down to the heroes, only to be friends with them in subsequent appearances? Sounds like a certain Chaud-ProtoMan duo.
  • Jerkass: Their scenario involves Raika punching Lan in the stomach and has SearchMan taking aim on MegaMan while on an anti-Nebula mission as a test. Bizarrely, you get Search Soul out of this event.
  • Jerk with a Heart of Gold: When he first shows up in the anime, he rags on Lan since Electopia's only defense against Nebula and their dark chips are cross fusion and essentially calls Lan a dumbass and claims that darkloids can be defeated using intelligence instead of relying on cross fusion and in the following episode, Raika orders SearchMan to fire at DesertMan, but SearchMan is reluctant since DesertMan is holding MegaMan over a lava pit which means if SearchMan deletes DesertMan, MegaMan would've also deleted. When SearchMan fires a freeze bullet at the lava, Raika scolds SearchMan, but finally shows MegaMan some respect but still insults Lan. When he returns later in Axess, he refuses Raoul's help thinking he'll get in the way due to being a civilian. The "heart of gold" finally comes in a few episodes later when FridgeMan takes over a mine in Sharo and unintentionally traps Sharo's heroic dog in the dimensional area. Raika previously known for following all orders uses Lan to bypass the dimensional area and risk getting himself in trouble just to save his friend.
  • Military Brat: Comes with him being a Russian (Sharo) soldier stereotype.
  • Not So Above It All: Despite his arrogant and cold personality Raika is eventually subjected to goofy moments in the anime, especially during Beast. Having to stick with the more comical Dingo is probably a factor too.
  • Redhead In Green: SearchMan is a redheaded Navi wearing a green military garb.
  • The Smart Guy: Of Team ProtoMan, as they are capable of searching and disarming enemy traps.
  • Serious Business: Mocks Lan for thinking Netbattling is a sport for people to enjoy.
  • Sugar-and-Ice Personality: The sugar part is more pronounced in the anime.
  • You Gotta Have Blue Hair: Raika has light green hair.

    Terry Jomon (Teruo Jomon) and SparkMan.EXE 

SparkMan voiced by: Yuto Kazama (JP), Don Brown (EN)

A robot specialist who wants to win the tournament so his grandfather, the owner of Jomon Electrics will give him funding for his projects.

  • Adapted Out: Terry never shows up in the anime.
  • Casting a Shadow: SparkMan can summon his opponents' shadows to attack them from behind.
  • Cheaters Never Prosper: He sends Lan a fake e-mail promising free PET maintenance, but is actually hacking into it so Lan can only use a folder with weak chips instead of his own so he can win the tournament. His grandpa helps Lan fix his PET and then expresses his disappointment in Terry and disowns him.
  • Locomotive Level: SparkMan's last appearance in Axess excluding The Great Net Police Battle has him taking over a train.
  • Never My Fault: Any Net Battle Terry loses, he blames on SparkMan.
  • Shock and Awe: SparkMan is an Elec Navi.
  • Taking You with Me: Right before he's deleted, he sabotages the train's braking system so the train will crash taking down MegaMan, Lan, and WoodMan.

    Atsuki Homura and BurnerMan.EXE 

BurnerMan voiced by: Shin-ichiro Miki (JP), Richard Ian Cox (EN)

A young man who's very passionate about pyrotechnics, essentially a younger, ruder version of Mr. Match.

  • Adapted Out: Atsuki never shows up in the anime.
  • Jerkass: He's rude towards Mr. Match, calling him an old man and laughs at him and Fire Man for losing to Lan and Mega Man in the past.
  • Meaningful Name: Homura means "flame'.
  • Out of Focus: Played with. As a Darkloid BurnerMan gets more episodes than most and is around for a large chunk of Axess, but he never returns as either an Asteroid Navi, or a Zoanoroid Navi unlike most of the rest.
  • Playing with Fire: BurnerMan is a Fire Navi.
  • Sore Loser: When Lan defeats him in the tournament, he angrily tells BurnerMan to burn down the whole building only to set himself on fire and runs into an elevator.
  • Technicolor Fire: Unlike other Fire Navis, BurnerMan ignites blue flames.

    Ivan Chillski (Ivan Coolski) and ColdMan.EXE 

Ivan voiced by: Katsumi Suzuki

ColdMan voiced by: Shinji Kawada (JP), Alec Willows (EN)

A man from Sharo (the Battle Network version of Russia) who loves the cold weather.

  • Animate Inanimate Object: ColdMan is a walking, talking refrigerator.
  • Disproportionate Retribution: He complains that Netopia is too hot for him. So what did he do? Went back to Sharo to infiltrate its weather control systems and causes blizzards around Sharo and Netopia.
  • Dub Name Change: ColdMan is called Fridge Man in the anime's English dub. Unlike most other name changes in the dub, this one actually makes more sense since he is indeed a sentient refrigerator.
  • Fat Bastard: He is the fattest character in the series and willing to freeze over the entirety of Sharo and Netopia just to make himself more comfortable.
  • An Ice Person: ColdMan is an Aqua Navi.
  • Karma Houdini: Supposed to be imprisoned in NetFrica for his crimes...only to appear in Sharo near the end of the game to cheer on Lan and MegaMan.
  • Scarf Of Asskicking: ColdMan wears one.
  • Too Dumb to Live: Ivan takes control of weather computers all over the world so he can cause blizzards in Netopia because its too hot for him, not realizing he can just take off his coat.
  • Well-Intentioned Extremist: The well intentioned part is debatable, but in the anime, Ivan lost his job due to the company running low on funds to support his compression research, when he receives Asteroid ColdMan, they begin compressing Navis all over the world, which leads to Chaud, ProtoMan, and Raoul arresting Ivan and deleting ColdMan.

    Tensuke Takumi and TopMan.EXE 

Tensuke voiced by: Masashi Hirose

TopMan voiced by: Kenichi Ogata

An elderly man who wants to bond with his grandson by playing with tops. He has an identical twin brother who makes kites.

  • Adapted Out: His twin brother never shows up in the anime.
  • Battle Tops: His only hobby are making and playing tops.
  • Cool Old Guy: He becomes this at the end of his only anime appearance. TopMan is a straighter example.
  • Grumpy Old Man: He is grouchy most of the time, unless his grandson is involved.
  • Palette Swap: The only design difference Tensuke and his twin brother have is that he wears red while his brother wears green.
  • Perpetual Frowner: Tying to Grumpy Old Man above. This makes his interactions with Kousuke jarring, all because characters can only have one mugshot (except in Double Team DS).
  • Pet the Dog: He genuinely loves his grandson Kousuke which is why he's trying to learn how to properly use the battle chips. Taken Up to Eleven when his mechanical top gets infected by a virus and scans Kousuke as its target and he practically begs Lan to help Kousuke and when the top scans Lan as its new target, he warns him to run.
  • Screw Politeness, I'm a Senior!: He doesn't get along with other people, not even other seniors initially and has a habit of yelling at everyone when he thinks the other seniors are implying he's stupid for not understanding the elemental type match ups.

    Shuko Kido and AquaMan.EXE 

Shuko voiced by: Mamiko Noto (JP), Chantal Strand (EN)

AquaMan voiced by: Chiemi Chiba (JP), Matt Hill (EN)

An unlucky girl working hard to support her younger twin brothers following their parents' deaths. She reappears in Battle Network 6 to introduce the Cross System in the Falzar version. AquaMan is a timid child-like Navi who is very concerned about his operator's well-being.

  • Badass Adorable: You know he's badass when AquaMan's a kid yet able to help MegaMan delete BurnerMan.
  • Born Unlucky
  • Brainwashed and Crazy: AquaMan gets possessed by Reverse in Legend of Network. He is also posessed by MegaMan DS courtesy of LaserMan in the fourth game.
  • Cute Clumsy Girl
  • The Dreaded: Storeowners avoid Shuko like plague as her bad luck caused problems to them.
  • Dub Name Change: AquaMan is called SpoutMan in the anime's English dub, which oddly transferred over to the sixth game.
  • Girlish Pigtails: Shuko styles her hair this way.
  • Making a Splash: AquaMan is an Aqua Navi.
  • New Job as the Plot Demands: Keeps changing jobs due to her bad luck.
  • Ocular Gushers: AquaMan cries so much to the point of flooding the entire internet, all due to a misunderstanding.
  • Out-of-Context Eavesdropping: When she and her brothers are thinking about replacing their washing machine, AquaMan thinks they're talking about him and want to throw him out for a new Navi.
  • Parental Substitute: She's this for her brothers while Higsby is this for her.
  • Promotion to Parent: Her parents have already passed away leaving her to raise her twin brothers. Thankfully, said brothers are either in high school or college and able to pull some of their weight around when it comes to supporting their family.
  • Vague Age: She looks young enough to pass as a teenager, but then her younger twin brothers are already in high school age. She is even a schoolteacher by the sixth game.
  • Verbal Tic: AquaMan peppers his sentences with "woosh!" (in 4) or "drip!" (in 6) all the time. It's "pyun!" in the Japanese version.
  • Weak, but Skilled: AquaMan's Soul Unison and Cross doesn't inflict a lot of damage, but has a very fast charge rate, similar to any Aqua element style change from the second and third games.

    Viddy Narcy (Narcy Hide) and VideoMan.EXE 

Narcy voiced by: Hiroshi Kamiya

VideoMan voiced by: Tomomichi Nishimura (JP), Don Brown (EN)

Real name: Hidenosuke Yamashita. An aspiring flamboyant filmmaker who joins the Neo WWW in the anime when he believes no one appreciates his ideas.

  • Adaptational Villainy: In the games, while he's definitely not nice, he's still not a villain. In the anime, he becomes a member of Neo-WWW. In Beast, he has a Beyondard counterpart who's the king of a town's criminal underground and abuses the citizens.
  • Ascended Extra: A minor tournament opponent in the games but part of a major villainous group in the anime.
  • Butt-Monkey: Particularly his Beyondard counterpart in Beast who keeps getting blown away by TenguMan.
  • Ditto Fighter: VideoMan can create a copy of MegaMan to fight for him.
  • Dude Looks Like a Lady: Seriously, just look at him. Viddy even lampshades this, claiming to "have gone beyond gender".
  • Evil Is Petty: Some of his evil plans involve getting revenge on people who have (from his perspective) wronged him, such as kidnapping Dex to make a huge pot of curry so he can drown Jawaii Island because he used to work for their tourism office but got fired.
  • Gameplay and Story Segregation: Some of VideoMan's cutscene abilities such as pausing the opponent and reversing their movements are never demonstrated in battle.
  • Never My Fault:
    • After losing to Lan and MegaMan in the fourth game tournament, he fully blames VideoMan for the loss and calls him a "useless Navi".
    • During his very short lived Heel–Face Turn in the anime, he wins Yai's Navi design contest, but gets disqualified since the contest is for kids. He accuses Yai of humiliating him, but as Yai points out, it was his own fault for not reading the rules.
  • Punny Name: Viddy comes from "video", referencing his profession and Navi VideoMan. Narcy is from "narcissist", fitting how highly he sees himself.
  • Real Men Wear Pink: Well, he certainly has this mindset.
  • Time Master: VideoMan can fast forward to accelerate himself and rewind to heal some damage.
  • Transgender: In the video games, possibly. They have a female chosen name (both Narcy could be viewed as a feminine sounding name, as well as Hide being a typically female name in Japanese meaning "excellence"/"esteem"), claims to have gone "beyond gender", and hates it when people use their birth name (which is a strictly masculine one) to the point of anger.
  • You Gotta Have Blue Hair: Has purple hair.

    Lilly (Igarashi Ran) and WindMan.EXE 

Lilly voiced by: Aya Hisakawa

WindMan voiced by: Shunsuke Sakuya
A priestess of WindMan's temple in Scissor Island. WindMan himself is revered as a god where Lilly comes from due to his tremendous powers. While normally calm, she has a dark side to her that is brought up when she is intoxicated.

  • Blow You Away: WindMan of course. To the point that enemy auras are blown off when Wind Soul is activated by MegaMan.
  • Dub Name Change: WindMan to WindBlastMan in the anime.
  • Lady Drunk: Lilly drinks when she's nervous. This causes a lot of problems to those around her.
  • Power Floats: Since WindMan is floating, panels do not affect him.
  • Power Incontinence: Once Lilly gets drunk and unseals WindMan's powers he causes massive storms across the Net.
  • Split Personality: Changes into a more violent version of herself anytime she gets drunk.

A solo Net Navi born from junk data who joins the tournament to have one last fight before his data decays.

  • Dead All Along: She died long before Lan was born. Her ghost lingers around as she is searching for a worthy opponent to fight with before she departs to the afterlife for good.
  • Palette Swap: The blue variant of the little girl NPCs.
  • Weirdness Magnet: Her presence attracts Navi Ghosts whenever she is having fun, much to her father's chagrin.

  • Enfant Terrible: A kid who depletes his village's water supply and installed viruses into the water management system to get back on Lan for winning the WaterGod Festival.
  • Foreshadowing: His actions is a reminiscent of Dr. Regal's plans in the fourth game; sabotage a Hikari who tries to solve a disaster (Yuichiro's laser cannon and Lan restoring the global network connection in case of Regal, Lan fixing the WaterGod in case of Paulie) to make them look bad so that they can step in with another plan and be seen as the heroes instead.
  • Palette Swap: He is a recolor of the blue shirt boy NPCs; giving him dark skin, white shirt and green shorts.
  • Sore Loser: Feeling jealous of Lan's victory in the WaterGod Festival he and his Navi stormed off to install viruses into the WaterGod so that when Lan and Mega tried to fix it they will get deleted by the viruses instead.


Voiced by: Hidetoshi Nakamura (JP), Scott McNeil (EN)

An autonomous Navi known as a Darkloid, Navis who are infused with power from a Dark Chip. He first appeared in 4 as an independent Navi who attacked other Navis to consume their energy and kidnapped Roll.EXE to have her for "dessert". He started out invincible to all attacks, which pushed Lan and MegaMan into using the Dark Chip he had dropped earlier. As he died he laughed that MegaMan was now infused with evil from the Dark Chip. He returns in 5 as part of Nebula, occupying the Net and helping towards the activation of Soul Net. In Axess ShadeMan was the leader of the Darkloids, turning a portion of the Net into their fortress. They were tasked by Nebula to perform missions in exchange for Dark Chips, which he discovered later would lead to their deletion. He was betrayed by Dr. Regal and his Navi LaserMan and later attacked them toward the end of the series, but was deleted by the cross fusion of human and Navi.

  • Adaptational Badass: In the games, while he was a Hopeless Boss Fight, he wasn't that much of a threat. In the anime, he's one of the strongest characters in the show.
  • An Arm and a Leg: While several antagonists (including ShadeMan himself in episode 27) lose their arms after particularly powerful attack, ShadeMan's Family-Unfriendly Death by the Cross Fused Regal included his right arm being shot off and his left arm being torn off. He is brought back in Stream, still armless, and ultimately takes Asteroid FlashMan's left arm and BeastMan's right.
  • Animal Motif: Bats, par for the course.
  • As Long as There is Evil: States in 5 that so long as there is Dark Power, the Darkloids will always come back from deletion.
  • Authority Equals Asskicking: In the anime, he's the leader of the Darkloids and by far the strongest.
  • Beard of Evil: Has a thin goatee and mustache.
  • Brought Down to Badass: Thanks to a crossover sidequest with Boktai where he was fried by the power of sunlight, he can be damaged by regular means. Doesn't stop him from being a badass, especially in his Omega form.
  • Casting a Shadow: Can create a hand of dark energy during his fights.
  • The Computer Is a Cheating Bastard: His Noise Crush attack lets him step into your side of the field regardless of how many spaces you have.
  • Curb-Stomp Battle: His first meeting with Lan and Chaud has him one-shotting them with Noise Crush.
  • Demoted to Extra: In his debut appearance he is a recurring threat to Lan and MegaMan to the point of having two Hopeless Boss Fights dedicated to him and when he is fought legit he actually rivals LaserMan, presumably intended as a follow-up to Bass' popularity and increased plot relevance in the previous game. His manga and anime incarnations also follow suit. In the fifth game however he doesn't do much and his power level has decreased somewhat, being one of the earlier Darkloids you face. CloudMan scored the most successes among the Darkloids while CosmoMan takes LaserMan's place as Nebula's commander.
  • The Dragon: To Dr. Regal in the anime.
  • Dragon with an Agenda: Only teamed up with Regal to further his own goals and for the Darkchips. Once he found out that Regal knew how dangerous the darkchips were, he double crosses him.
  • Evil Sounds Deep: Has a very deep voice in the original version.
  • Family-Unfriendly Death: Having both your arms violently ripped off and an explosion tear you apart from the inside isn't exactly approved for younger audiences. Hence the dub censoring most of it out. He's even MORE brutally eviscerated in the manga. By MegaMan himself, no less.
  • Handicapped Badass: In Axess, Cross Fusion MegaMan and ProtoMan unleash a double Program Advance on him. All it does is destroy one of his arms and when he's forced back into cyber space, he doesn't have much trouble beating up MegaMan and ProtoMan. In Stream, after Regal rips both of his arms off, but before he gets deleted, he's accidentally brought into the future and proves to once again be a challenge for Cross Fusion MegaMan and ProtoMan until Ms. Yuri intervenes and later literally disarms Asteroids FlashMan and BeastMan.
  • Hopeless Boss Fight: The first two fights with him in the fourth game, you can't hurt him with anything besides Dark Chips in the 2nd fight. The only way to fight him properly there is to do the Django sidequest in the Undernet, which upon completing it will release his Omega form in Undernet 4 as a random encounter.
  • I'm a Navitarian: In the games, he feeds on the energy of other Navis.
  • I Have You Now, My Pretty: With his intended "dessert" Roll.
  • Made of Iron: Even as far as NetNavis go, he's pretty damn durable. For one example, he was struck by a double Program Advance from Lan and Chaud, but aside from blowing off one of his arms, it didn't even slow him down.
  • Make Me Wanna Shout: His Noise Crush ability.
  • No Celebrities Were Harmed: Ishihara stated he had an image of Nobunaga Oda in his mind when designing Shademan.EXE.
  • Our Vampires Are Different: A vampire-themed computer program.
  • Power Floats: He notably floats all the time, without the help of his wings. This is actually important when Megaman has to chase him to save Roll, has there's a giant gap in the way that Shademan just floats over.
  • Roaring Rampage of Revenge: After using Rush to materialize himself into the real world without a dimensional area, he goes on a rampage throughout the city, destroying everything that belonged to Regal to draw him out.
  • Rubber Man: The anime gives Shademan the ability to stretch his arms.
  • Verbal Tic: Has a tendency to say "WHEE!" in the games.
  • Winged Humanoid: He can turn his arms into wings, usually to perform his Noise Crush.
  • Wolverine Claws: His claws are his main weapons.

    Dr. Regal 

Voiced by: Kazuhiro Nakata (JP), Trevor Devall (EN)

The leader of Nebula, Dr. Regal seeks to take over the world and plunge it into an age of evil and darkness. In the fourth game, he attempts to achieve this by taking over Duo's Comet. In the fifth game, he attempts to activate Soul Net, which links humans to the internet where he can tamper with their emotions. His Navi is LaserMan.EXE.

  • As Long as There is Evil: Leaves Lan to ponder this in the epilogue of the fourth game.
  • Avenging the Villain: In the games, he's the son of Dr. Wily.
  • Beard of Evil: In the fifth game.
  • Big Bad: Games 4 and 5. Axess season and The Movie.
  • Black and Gray Morality: Mocks any conjecture of heroism.
  • Broken Pedestal: His father's fall to villainy caused him to become disillusioned with both Wily and the society that rejected him.
  • Card-Carrying Villain: Makes absolutely no bones about his willingness to do horrible things to people.
  • Chekhov's Gunman: He's always been the head of Nebula, but that was largely an issue on the back burner of the story until late in the 4th game. In the 5th game he actually has a plot to enact.
  • Cold-Blooded Torture: Does this to Dr. Hikari in the fifth game.
  • Evil Cannot Comprehend Good: Yuichiro bowls the good doctor over in the ending of the fifth game.
  • Evil Versus Oblivion: He uses himself as a conduit for a broken cable so that Lan and MegaMan can stop Duo, but only because he can't create his world of evil if everyone dies.
  • Eviler Than Thou: To ShadeMan in the anime.
  • Eye Scream: In the movie, he kidnaps Yuichirou and performs laser eye surgery on him to extract the last remaining data for Nebula Grey.
  • Family-Unfriendly Death: In the anime. He also very clearly commits suicide by falling backwards off a roof in the fourth game, though the fifth reveals he lived. In the manga, he makes a successful escape with his personal submarine... until Bass catches up with him and destroys it wholesale. Inflicts one on ShadeMan in Axess. It is not fun at all watching Shade screaming as his arms are ripped off. Even less pleasant is when he gets hit point blank with LaserMan's Cross Laser, which actually manages to explode out of him.
  • Faux Affably Evil: Despite being a Card-Carrying Villain, he has moments of false politeness and benevolence, such as when he calmly tortures Dr. Hikari, gives him False Reassurance that the theory behind Soul Net won't go to waste, and tells the public via a live broadcast that they'll soon be "free" of their morality.
  • Heel–Face Turn: Yuichiro urges him to do this, specifically returning to the mouth of an erupting Mt. Belenus to offer him a Last-Second Chance. While his mind reels at this (and with good reason), Regal feebly manages to refuse. And then Papa Wily Shows Up and gives him a Bright Slap to remember. Or Not.
  • Humans Are Bastards: His motivating principle, derived from society's rejection of his father. His plot in 5 basically amounts to him putting every human mind through hell and watching as the world tears itself apart.
  • In the Blood: A revenge-driven mad scientist? Yeah, he Turned Out Like His Father, alright. Ancestry is a recurring theme between him and Yuichiro.
  • I've Come Too Far: After Yuichiro tries to reason with him, Regal actually starts showing some regrets about his philosophy, only to say that he committed too much evil to change his ways. Then Dr. Wily overloads Soulnet and erases his memory.
  • Killed Off for Real: In the anime, Duo ages him to death as punishment for his actions in Axess and the (undubbed) movie.
  • Laser-Guided Amnesia: His fate at the end of the fifth game.
  • Laser-Guided Karma: He tries to brainwash all of humanity into evil using the Soulnet. He's then forced into a Heel–Face Brainwashing by that very same system.
  • Light Is Not Good: While his navi Laser Man has light-based powers, he is just as evil as his operator.
  • Mind Rape: This is basically what happens to people caught up in his version of Soul Net.
  • Never Found the Body: In the fourth game. He returns as the Big Bad of the fifth game.
  • Not That Kind of Doctor: Shows up as a subtle play in the manga - Dr. Regal, after having been revealed as infiltrating the Netopian army with Darkloids, introduces himself as "assisting with a birth."
  • One-Winged Angel: At the end of Stream, he transforms into a huge serpent with a human head. Not that it avails him much...
  • Shadow Archetype: Of Yuichiro. World-renowned scientist responsible for major leaps in technology? Check. Child of a likewise famous scientist? Check. Develop technology intended to benefit mankind? Ha ha ha no.
  • To Create a Playground for Evil: His ultimate goal.
  • Trailers Always Spoil: One actually went out of its way to point out who the villain was.
  • The Unfavorite: His father Dr. Wily pays more attention to his deceased friend's son and neglected his own.
  • Verbal Tic: As a Card-Carrying Villain, he always makes sure to include the word "evil" in his dialogue.
  • Villain with Good Publicity: Well, almost. Hailing from an infamous military state, he's universally recognized as one of the most dangerous men on the planet, but in the face of imminent doom, Yuichirou and the assembled are... not entirely unwilling to work with him.
  • What the Hell, Hero?: Challenges the heroes' simplistic views of Good and Evil during the climax of the fourth game. Accuses Chaud of slaughtering countless "criminal" Net Navis during his tenure as an Official, and accuses Lan of being similar when he hunted down the Net Navi responsible for severing global network connections...which almost certainly establishes him as a Troll, since the Heel Navi in question, who had to have a good idea of the magnitude of his actions, attempted kamikaze suicide when he was cornered.

"Ha! The warmth of souls indeed... Listen to me. That feeble power is no match for the power of evil."

Dr. Regal's NetNavi and the leader of the NetNavis in Nebula in Battle Network 4. Is succeeded by CosmoMan.EXE. In the anime, he usurps ShadeMan as the leader of the Darkloids.

  • Abnormal Limb Rotation Range: Is capable of rotating his head a full 360 degrees in the anime. Justified in that he is designed to look robotic.
  • Adaptational Badass: In the games, while powerful, he's not that big of a threat. In the anime, however, he's capable of curbstomping ShadeMan, who Lan and Chaud could barely defeat.
  • An Arm and a Leg: Gets his hand cut off during his fight with MegaMan in the anime.
  • Asskicking Equals Authority: He becomes the new leader of the Darkloids after deposing ShadeMan.
  • Attack of the 50-Foot Whatever: In the anime, Dr. Regal uses data from viruses to create several giant copies of Laserman to attack the city. He even merges with one of them to fight MegaMan.
  • Badass Baritone: Has a deep, robotic voice in the anime.
  • Bad Boss: In the anime, he deletes a Darkloid when the latter questions his decision to make Protoman his second in command. And he later orders ProtoMan to kill Ms. Yuri when her loyalty comes into question.
  • Card-Carrying Villain: Like his operator, he admits he is evil and mocks notions of justice.
  • Casting a Shadow: In BN4, he forces the darkness in Megaman to come to life and fight him. There's also his Dark Laser attack, where he fires a laser from his eyes that creates a dark void to heal him.
  • Chest Blaster: Can fire a laser from his chest in the anime.
  • Dark Is Evil: Has black armor, uses darkchips, and seeks to conquer the world.
  • Death from Above: His Star Break Laser, where he fires a red laser at the ceiling that causes debris to fall from the sky.
  • The Dragon: To Dr. Regal.
  • Dragon-in-Chief: He is in charge of the Navis in Nebula.
  • Evil Wears Black: Has black armor.
  • Eye Beams: His Cross Laser and Dark Laser.
  • Frickin' Laser Beams: Well, duh.
  • Fusion Dance: With Dr. Regal in the anime.
  • Generic Doomsday Villain: In both the games and anime, LaserMan has little personality and is more or less your stereotypical villain. In the anime however, it's implied he's just a simple drone program if not something directly controlled by Regal himself since the Darkloids won't obey a human and isn't a real navi. Thus he has no true will of his own.
  • Hand Blast: His Disruption Beam, where he fires a blue laser from his hand that temporarily disables the customization screen if it hits.
  • Killed Off for Real: Is defeated by MegaMan in both the games and anime. Particularly in the anime, both he and Regal are destroyed due to their Cross Fusion. While Regal is revealed to be alive in the movie, LaserMan is gone for good. As Regal could enter the net himself then he had no need of LaserMan anymore.
  • Light Is Not Good: His powers are predominantly light-based, but he is just as evil as his operator.
  • Orcus on His Throne: In both the games and anime, he mostly sits back and lets his subordinates do the work and doesn't take action himself until the finale. Taken literally in the anime as most of his onscreen appearances have him sitting on ShadeMan's throne.
  • Puppet King: The anime heavily implies that he is just Regal's virtual mouthpiece.
  • Talking to Themself: Shares the same voice as Regal. Possibly because Regal's actually just talking through him directly.
  • Tron Lines: Has blue lines running all over his armor.
  • We Can Rule Together: Offers this to MegaMan. Works as well as you expect.
  • You Could Have Used Your Powers for Evil: How he feels about MegaMan.

Duo is said to be an advanced Navi from a universe far away, created to test and judge life across space and punish said life if they are deemed to be evil. His ultimate method of punishment involves slamming his comet into a planet. He arrives to judge humankind in the fourth game and in the anime season Stream.

  • A God I Am: Never outright stated, but seeing as he thinks he's the right to destroy entire planets based his judgement of them as evil, he definitely qualifies, especially in the anime where that's shown to be a self-appointed role.
  • Chest Blaster: The port on his chest can fire laser beams with rings surrounding them, making it harder to dodge it.
  • Cosmic Entity
  • Deus Est Machina
  • Did You Just Punch Out Cthulhu?: In the games, Lan and MegaMan actually defeat him in combat.
  • Expy: Of Galactus, and The Celestials. His overall look, and the fact he has a herald (Slur) in the Anime, recalls more Galactus, but his tendency to judge whole planets, and a more cybernetic nature, harkens more to The Celestials. Also of course one of the original Duo.
  • Final Boss: Unlike the other final bosses in the series, he has nothing to do with the main antagonistic group but he serves as one for the fourth game.
  • Humanoid Abomination: Vaguely humanoid and is apparently a kind of being analogous to Navis.
  • Humongous Mecha: His battle-body's aesthetic. His official art emphasizes how humongous he is.
  • Karma Houdini: Anime only. Despite threatening to destroy the Earth and destroying his own planet he gets away with everything he did.
  • Light 'em Up: Downplayed. Duo has a laser-cannon in the center of his battle-body, but the real danger is that he makes it impossible to use Dark Chips in battle.
  • Mysterious Backer: Provides some minor assistance in the last two games by granting MegaMan battle chips that summon his fists.
  • Nightmare Face: Weaponized. At low health, he will project an angry face as a laser attack that cracks panels.
  • Power Fist: Most of his attacks involve attacking with his giant knuckles. This comes up in several Mega and Giga chips associated with him.
  • Outside-Context Problem: He isn't evil per se, but he's still a threat completely separate from the rest of the game, having nothing to do with any of the other characters except that they're on the planet he's going to destroy.
    • He also has nothing to do with the overall Wily/WWW story plot that every other final boss of the series is connected to. He just happens to appear during a lull in it.
  • Physical God: Taken Up to Eleven in the anime, where he is invincible.
  • Restored My Faith in Humanity: His final fate in the game.
  • Turned Against Their Masters: Only in the anime, where the first planet he judged and destroyed, was the one of his creators. Subverted, that he killed the navigators of his world too. Althrough in the finale of Stream, he also tried persuading the navis to abandon their operators, so he also played it straight.
  • The Voice: He's the one who tells you about Chaos Unisons and gives you chips themed after his attacks from the fourth game in Battle Network 5.

Alternative Title(s): Mega Man Battle Network 4
