List of Mega Man characters

This is a list of characters from the Mega Man series. In Japan, the Mega Man series is known as Rockman.

Main characters

Mega Man

is the hero of the games, created by Dr. Light, with assistance from Dr. Wily. Originally created as a lab assistant named "Rock", he was modified for battle after Dr. Wily reprogrammed the original Robot Masters. Due to his Variable Weapons System, he can copy the weapon of any Robot Master he defeats in combat and use it as his own.

Dr. Light

Doctor Thomas Light, known in Japan as , is depicted as an aged scientist, who is a peerless roboticist and winner of the Nobel Prize. He is the creator of protagonist Mega Man and several other robots. While a pacifist, he reluctantly recognizes that the use of force can be a necessity. He plays a supporting role, often developing and distributing new gear. In the Mega Man X series, Dr. Light resumes his supporting role through enhancement capsules that contain upgrades to X's systems together with messages relayed by silver/blue, slightly translucent holographic projections.

His counterpart in the MegaMan Battle Network series is Dr. Tadashi Hikari, the founder of network research in parallel to Light's involvement with robotics.

Dr. Wily

Introduced in the first Mega Man game, scientist was originally Dr. Light's partner, and helped him create a series of humanoid robots to help mankind, such as the boy robot Rock and the construction robot Guts Man, though the world ignored his contribution. Out of jealousy for Light, he reprogrammed the robots, with the exception of Rock, to assist him in taking over the world. He was however defeated by Rock, who voluntarily upgraded to the combat robot "Mega Man". Wily returned as the antagonist in subsequent titles of the main series with a different scheme each time, only to be defeated and surrender to Mega Man at the end.

Wily has also been instrumental in the backgrounds of other characters in the series. He repaired the prototype for Mega Man, "Proto Man", and in Mega Man 7 used what he learned during the process to create his answer to Light's work, Bass. After Bass proved to be unreliable, Wily refined his design, creating the robot Zero. Zero would appear in the Mega Man X and Mega Man Zero games as a hero working alongside Light's last creation, "X". Though Wily died prior to the X series, his legacy continued through a virus initially carried by Zero and transferred to Sigma, creating the X series antagonist "Sigma Virus", along with all the Mavericks.

Dr. Wily ranked sixth on IGN's top 10 list of video game characters who should die along with his nemesis, Dr. Light. IGN editor Colin Moriarty stated that while their rivalry may have been fascinating for over 20 years, they need to go so the core series may advance.

Proto Man

Proto Man, known as in Japan, is the early prototype of Mega Man that made his first appearance in Mega Man 3, under the name of Break Man, to help train Mega Man by fighting him. Beyond their armor and personality, Proto Man and Mega Man are supposedly identical. At the end of , it is revealed by Dr. Light that Proto Man's body has a fatal defect in his energy system, and as a result, is in great pain and has a more limited lifespan.

As Proto Man's design is similar to Mega Man's, he has similar capabilities, with his primary weapon being an arm cannon. His arm cannon is much more powerful than Mega Man's and it can produce a variety of shots, including the "Big-Bang Blast", a large concentration of Proto Man's remaining energy put into a blast so powerful that it can damage his body. He has also been shown to have the same weapon-copying powers as Mega Man, with his body changing color in a similar fashion depending on the weapon acquired. He carries his unique Proto Shield, which can deflect projectile attacks.

The main series games in which Proto Man is playable are Mega Man Powered Up (a PSP remake of Mega Man 1), Mega Man 9 (as a downloadable character) and Mega Man 10 (unlocked from the beginning). Unlike Mega Man in those games, he can slide and charge his arm cannon. He can also block attacks with his shield, but only while jumping, and shares the ability to absorb weapons from defeated Robot Masters. However, he suffers double damage and is knocked back twice as far on contact compared to his brother. Also, Proto Man may only shoot two pellets at a time, whereas Mega Man can shoot three.

Bass

is a robot designed by Dr. Wily. He was constructed based on research conducted on Mega Man with the intention of matching his power. Wily makes mention of discovering the energy that powers Bass, Bassnium, the most powerful form of energy on Earth, entirely by mistake. Despite being created by Wily, Bass frequently rebels against his creator when he feels Wily is standing between him and defeating Mega Man. His desire to defeat Mega Man and be acknowledged as the world's strongest robot borders on fanaticism. Though he wants to defeat Mega Man, Bass has worked together with him against a common enemy, though usually for his own purposes.

Bass's weapon is the powerful Bass Buster, which functioned similarly to the Mega Buster for his introduction in Mega Man 7, albeit with slightly different shots. As of Mega Man & Bass, however, the Bass Buster has lost its ability to charge its shots in favor of a drastically increased rate of fire and ability to fire upwards and diagonally. Unlike the Mega Buster, the bullets do not travel through solid surfaces unless an upgrade is acquired and equipped. Like Mega Man and Proto Man, Bass can also copy the weapons of Robot Masters, his body changing colors to reflect the weapon currently equipped. He can also combine with his robotic wolf , allowing Bass to take flight and shoot more powerful projectiles from his buster.

Save for a cameo showing a schematic of Bass, Bass is absent in Mega Man 9. His absence was not explained, although according to the booklet that came with the Rockman 9 Arranged Album, Bass was undergoing some adjustments and was being upgraded by Dr. Wily. He is playable in Mega Man 10, retaining his dash and rapid-fire, multi-directional arm cannon capabilities (though not his double jump), if additional downloadable content is purchased for the game.

In , Zero makes a cameo appearance, and Wily says that it is a creation that will surpass even Bass itself. Bass says that he will destroy this creation, and that no other robot is more powerful than he is. It's not explained what happened to Bass before the events of Mega Man X.

The character is named after the musical term bass ( as in base), not the fish (). However, in the Mega Man 8 intro, Mega Man mispronounces his name like the fish rather than like the musical term. The name is likely related to the rock 'n' roll theme of Rockman and Roll.

Supporting characters

Auto

Auto (Rightot in Japan) was created by Dr. Light as a lab assistant, due to Rock being unable to fulfill that role after his adoption of the superhero identity "Mega Man". He is introduced in Mega Man 7, where he provides Mega Man with upgrades and parts. In Mega Man 8, Auto assists Mega Man in the Rush Jet scenes, using a rocket launcher as well as a propeller in his head that allows him to fly. He also appears in Mega Man & Bass, creating upgrades for the player in exchange for 'bolts' dropped by defeated enemies. He also made a cameo appearance in CD versions of Mega Man X3, watching TV in the background of the FMV intro for Volt Catfish's stage.

Beat

Beat is a robotic bird that has appeared continuously in many Mega Man games. He was created by Dr. Cossack to provide additional support to Mega Man during the events of Mega Man 5. Beat homes in on enemies, providing damage by physical contact. He would perform the same function in Mega Man 6, however he would not attack bosses as he did in the previous game. In Mega Man 7 and Mega Man 9, he rescues Mega Man from pits and in Mega Man 8, assists Mega Man during the Rush Jet scenes. He also provides Mega Man with an energy barrier in Mega Man & Bass. He assisted Duo and Proto Man as temporary invincibility powerups in Power Battle.

Bio-Devil

The Bio Devil is a mechaniloid first created by Dr. Wily. Other versions appear in the various series of the Mega Man metaseries. All of the Bio-devils consist of a ball-shaped body with over-proportionate hands and feet. At the center of the body is a single, mechanical eye. This eye is what keeps the bio-devil together and is also its one and only weakness. Each utilizes its malleable body substance and brute strength to lash out at intruders. Each version has a different name, including the Yellow Devil, Green Devil, Black Devil, Rainbow Devil, Lava Devil, Twin Devil, and Block Devil.

In the American version these creatures are referred to as "Rock Monsters", a change made due to Nintendo's policies regarding religions figures and names. However, the "devil" names are used in more recent American releases.

Sniper Joe

Sniper Joe is a mechaniloid used as infantry by Dr. Wily. It physically resembles a green Proto Man with a single red eye instead of sunglasses. This resemblance can be credited to the Sniper Joe series being modeled after Proto Man. It has no real intelligence, and simply blocks forward attacks with his shield, then shoots a number of shots from its arm cannon (The exact number of shots depends on the model of the Sniper Joe). It can also jump into the air, during which it lifts up its shield, leaving an opening for Mega Man to attack him. Mega Man can also damage him as he moves his shield out of the way directly before firing. In Mega Man 8 and Mega Man & Bass, the Joe Classic can also throw grenades that explode after a certain period of time. It is stated multiple times that Proto Man considers these abominations, probabaly since they are based upon him but with limited intelligence.

Dr. Cossack

Dr. Mikhail Sergeyevich Cossack was a Russian colleague of Dr. Light. He appeared in Mega Man 4 as the main antagonist; however, it turns out he was being blackmailed, as Wily had kidnapped his daughter Kalinka. When Kalinka was rescued by Proto Man and the truth was revealed, Dr. Cossack turned on Wily and becomes an ally to Mega Man. He is the inventor of Beat and the Super Mega Buster, as well as numerous industrial and military robots. He also appears in the "Navi Mode" of Mega Man 5 in the Mega Man Anniversary Collection to provide gameplay hints to Mega Man.

Dr. Cossack is likely named after Peace Prize-winner and the last president of the Soviet Union, Mikhail Sergeyevich Gorbachev, although Gorbachev is not of cossack descent.

Duo

Duo is a robot made on an alien planet, designed to eradicate "Evil Energy". Duo was formally introduced in Mega Man 8, chasing the adult stage of evil energy in its final form. After crashing to Earth, he is repaired by Dr. Light, and soon becomes an ally of Mega Man. After finally defeating the evil energy on Earth, he thanks Mega Man and leaves Earth to resume his search. He later appears in , which was actually released before Mega Man 8, Mega Man Battle & Chase, and Rockman Strategy.

The bulk of Duo's offensive abilities are attributed to his powerful left arm, with a fist nearly as large as his own torso, and his large spiked body. He attacks primarily by punching, though he is capable of using projectile weapons, the most powerful of which is a blast in the shape of his own hand. He also appears to have the same weapon copying abilities displayed by Mega Man, Proto Man, and Bass. As with them, his body changes color in accordance with the weapon he has equipped. Also, having been created for the purpose of destroying evil energy, he seems to have the unique ability to purge said energy from an infected victim's body, as demonstrated when saving Mega Man.

Eddie

Eddie, also known as Flip Top, was created by Dr. Light as a "walking suitcase", usually sent to help Mega Man by providing recovery items during the game. He is also able to fire bombs out of his head while assisting Mega Man in the Rush Jet sections of Mega Man 8. Eddie first appeared in Mega Man 4.

Being that Eddie is a walking head, he might be a reference to Iron Maiden's mascot Eddie the Head.

Kalinka

Kalinka Cossack is Dr. Cossack's daughter, who was kidnapped by Dr. Wily in order to force her father into declaring war against Mega Man on Wily's behalf. She was however rescued by Proto Man right before Mega Man managed to defeat Cossack in his citadel. Kalinka is not present in any other games in the series, but appears in the "Navi Mode" of Mega Man 4 in the Mega Man Anniversary Collection to provide gameplay hints to Mega Man.

Kalinka is named after the famous Russian song of the same name.

King

King is a robot appearing in Megaman and Bass that appeared to have free will and had decided to create a robot empire and wipe out humanity (similar to Sigma in the later Mega Man X series). In the game, Mega Man and Bass had to fight him and many robots that had "joined" him (two recurring from Mega Man 8). When either one finally defeats King, it's revealed that he had actually been programmed to form a rebellion along with the other robots (and thus didn't actually have free will) by Dr. Wily, at which point the player must then defeat Wily. While King is assumed dead, during the ending it is revealed that he survived and is now a wanderer, much like Proto Man. He then apologized for his actions that he had caused and wishes to meet up with Mega Man peacefully.

Stardroids

Stardroids are the alien robot masters that were featured in Mega Man V (Game Boy). Their true creator is unknown. Dr. Wily had activated them as part of his plans to dominate the Earth. Unlike any bosses Stardroids is the only one have a lot of attacks which is very unperdition.

*Sunstar (Sungod in Japan) is the ancient robot Dr. Wily based his "Stardroid" designs on in Mega Man V. He was apparently built by an ancient alien civilization in the solar system that is long gone by the time Wily discovered him. These details suggest that Sunstar's creators are different from Duo's creators. When Mega Man finds Wily, he decides to activate Sunstar himself and orders him to destroy Mega Man. Instead, Sunstar reveals his independent nature by deciding to attack Wily, and then he decides that organic beings in general should be wiped out for creating so many weapons and attacks Mega Man for defending them. Sunstar is possibly the most powerful of the robots in the series (save for Duo) as his shots disintegrate entire floors during the final battle and he was able to knock out Wily's UFO with a single shot. Upon defeating Sunstar, Mega Man attempts to convince him that not all humans are evil, and while Sunstar seems to agree, he reveals that Mega Man has damaged his energy core and when he explodes, it'll take out the entire space fortress, and so Mega Man is forced to escape without him.

*Terra is the first Stardroid that Mega Man encounters. Terra defeats him easily, since his Mega Buster cannot damage him until Dr. Light upgrades him with the Mega Arm (which replaces his standard charge shot with a grabbing attack). After Mega Man defeats the 8 other Stardroids, he encounters Terra again, this time with the ability to destroy him. His name is based on Earth and the third planet of Solar System. His main attack is the "Spark Chaser", a laser which can home in enemies and damage multiple times not only that he can Teleport and fire a circle projector that will freeze Mega Man.

*Mercury is one of the first group of Stardroids. His name is based on the Roman messenger god of trade and the first planet of the solar system. His main attack is the "Grab Buster", a projector that can steal energy or power-ups from Mega Man and he can transform into liquid metal hopping in thrice and repeat the process. If you don't attack quickly enough, P-Chip and other power-up will be stolen by him.

*Venus is in the first group of Stardroids. He is named after the Roman goddess of love and the second planet of the solar system. His main attack is the "Bubble Bomb". If it is small, it can travel direction but big only just stay one side until it explodes. His stage is really difficult as a lot of bubble as small can weak jump and Big can high jump and hit to the spikes. His design looks very similar to "Toad Man" from Mega Man 4.

*Mars is in the first group of Stardroids. He is named after the Roman god of war and the fourth planet of the solar system. His main attack is the "Photon Missile", as he fires thrice and fires all missiles from his arm after that he will set mine and move to the other side and repeat the process. He is one of the dangerous Stardroids, it is highly recommended to take Neptune out before head his stage.

*Neptune is in the first group of Stardroids. He is named after the Roman god of water and sea and the eighth planet of the solar system. His main attack is the "Salt Water" which resembles and is reminiscent of Toxic Seahorse's weapon (Acid Burst) from Mega Man X3 . He jumps to the other side and keep jumping until all the sidling is drop all the object down to hit Mega Man after that he use his attack when Mega Man gets near him.

*Jupiter is in the second group of Stardroids. He is based on the Roman supreme deity and the fifth planet of the solar system. His main attack is the "Electric Shock", as he flies around and shoots at Mega Man. It is recommended to use "Bubble Bomb" to take him out.

*Saturn is in the second group of Stardroids. He is based on the Roman god of agriculture and harvest and the sixth planet of the solar system. His main attack is the "Black Hole". First, he jumps to the middle and freezes time attack with projector except bottom, after that he slides to the other side and uses his Ring to create a Black Hole and try to suck Mega Man into it. He is also one of the dangerous stardroid's and is highly recommended to take out Jupiter first before you heat to his stage.

*Pluto is in the second group of Stardroids. He is named after the Roman god of the underworld and the ninth planet of the solar system now classified as "Dwarf Planet". His main attack is the "Break Dash". He uses his claw fire triple beam and dashes to the upper left and fires missiles thrice and drops down on the floor repeating the process. His style is similar to Neon Tiger in Mega Man X3.

*Uranus is in the second group of Stardroids. His name is based on the Greek mythological god of the skies, and ancestor of gods, and the seventh planet of the solar system. His main attack is the "Deep Digger" which resembles Guts Man's weapon from the original Mega Man NES game as he uses this attack to pick up the blocks underneath him to throw at Mega Man. His defense is incredibly tough that even a fully charged "Mega Arm" can only damage a small percentage of his life bar.

Mega Man Killers

The Mega Man Killers are a series of robots appearing in the Game Boy series. The Mega Man Killers are robots created by Doctor Wily to destroy Mega Man, who in turn defeats each one of them and eventually foils Wily's most devious schemes. All of them reappear as bosses in Game Boy version of Mega Man V, and all of them also reappear as bosses in the DLC stages from Mega Man 10. All of them are named after notable music genres.

*Enker (RKN-001) is the Mega Man Killer of . He wields a javelin, but his main attack is his "Mirror Buster", which allows him to absorb Mega Man's buster shots and fire them back through his javelin, though by doing this, he damages himself. In addition to the latter group appearances, Enker also appears in , as the first fortress boss in Mega Man Soccer, and as the boss of the first DLC special stage in Mega Man 10. His name most likely comes from Enka, a Japanese musical genre.

*Punk (RKN-002) is the Mega Man Killer of Mega Man III. He is armed with the "Screw Crusher", a weapon that flings rolling blades at Mega Man, and he can also hurl himself after transforming to strike with his embedded blades. He also appears in Mega Man 10 as the boss of the second special stage, and is also the only Mega Man Killer to have a Battle Network counterpart, appearing in Mega Man Battle Network 3 as Mr. Famous' NetNavi. He reappears as the boss of the second DLC special stage in Mega Man 10. He is named after the Punk Rock musical genre.

*Ballade (RKN-003) is the Mega Man Killer of Mega Man IV. His weapon is the "Ballade Cracker", which can lay immobile timed mines and also fire small explosives from the tops of his arms. Ballade, after being defeated, seems to turn against Dr. Wily, and self-destructs to destroy a wall obstructing Mega Man, thus allowing Mega Man to escape back to Earth safely from Wily's space fortress. He also appears in Mega Man 10 as the boss of the third DLC special stage. His name is actually a modification of the word, Ballad.

*Quint is not a Mega Man Killer, but is confused by fans to be one as he serves a similar role in Mega Man II, although he is not actually part of that line of robots. However, he does appear in Mega Man V after Enker is defeated, which confuses the fans further. His weapon is a jackhammer/pogo stick amalgamation called "Sakugarne" which can attack his foes by digging into the ground and creating debris to fly up and hit Mega Man. There is some inconsistency about his origin- the Japanese version of Mega Man and Bass states that he was built in the future by Dr. Wily. This is contradicted by the English version of the game, which instead claims that he is a future version of Mega Man reprogrammed by Dr. Wily.

Met

The Met (short for the Metall, Metool, Mettenna, and Mettaur variants of the name), also known as "Hard Hat" is another flagship enemy of the series. Appearing in nearly every game, the average Met is a tiny construction robot wearing a disproportionately-sized hard hat with a "plus" sign marked on it. Mets usually wait below their helmet before attacking, as it is to nearly all of Mega Man's weapons. They appear in the various series of the Mega Man metaseries, with many different variations and forms. In the original Mega Man, another common enemy character named the Picket Man, has a head similar to the Metool, but with a full body. The Mets are a staple to the Mega Man series as the Goombas are to Super Mario Bros.

Reggae

Reggae is a robotic bird who is the pet of Dr. Wily. He is featured in an drama CD featured only in Japan. He was featured in (or RockBoard for short) and as a weapon for Bass. His first cameo outside of Japan is in Mega Man 7, where he appears if an invalid password is entered. He also appears as the shop keeper when playing as Bass in Mega Man 10.

Robot Masters

Robot Masters are a special kind of robot, mainly under the control of Dr. Wily, that possess a very advanced level of artificial intelligence. The system is jointly credited to Dr. Light and Dr. Wily, and most Robot Masters possess a unique identification code, consisting of a two-letter "series code" followed by one of N, No, or #, then a three-digit "serial number". They are generally humanoid in appearance, and they are often designed with specific purposes and human-like personalities and quirks. The list below is of the first six Robot Masters that were built by Dr. Light and reprogrammed by Dr. Wily, as well as two more that were retconned in Mega Man Powered Up so as to be consistent with other Mega Man games.

Mega Man 1/Mega Man Powered Up Robot Masters

{| class="wikitable" | Series Number | Japanese Name | Short Description | Weapon |- | DRN-003 Cut Man | Cut Man (カットマン) | Cut Man was originally designed for land reclamation work; particularly deforestation. His battle abilities center around his advanced jumping abilities and the pair of boomerang-like shears on his head. As revealed in Mega Man: Powered Up, he is easily fooled, and can turn his scissors into a more shuriken-like weapon. Cut Man also made a prominent cameo in the episode "Mega Trouble for Megaland", he appears in the Mega Man cartoon, and he has a cameo appearance in the Sega Saturn version of Mega Man 8 as well as Mega man X8 if certain conditions are met. | Rolling Cutter (ローリングカッター) |- | DRN-004 Guts Man | Guts Man (ガッツマン) | Guts Man was also designed for land reclamation work, but was created specifically for construction of public works. By far the strongest of any robot, Gutsman is able to lift objects of up to 80 tons over his head and hurl them at his foe with startling accuracy. In Mega Man: Powered Up, he's a little dim-witted, but always well-meaning robot. He appears in the cartoon series. | Super Arm (スーパーアーム) |- | DRN-005 Ice Man | Ice Man (アイスマン) | Originally designed for the exploration and mapping of regions far below the temperature that humans can withstand, Ice Man also supervises transportation of supplies to various research teams on the continent. Afterwards, he got the job of transporting materials in frozen food warehouses. He has the ability to shoot waves of super-chilled air from his mouth which is laced with liquid nitrogen, that then crystallizes into a projectile. Mega Man: Powered Up reveals Ice Man to possibly have a bipolar disorder, and his personality is like that of a soldier (and his commanding officer). Ice Man resembles a hooded Inuit. | Ice Slasher (アイススラッシャー) |- | DRN-006 Bomb Man | Bomb Man (ボンバーマン) | Bomb Man was also designed for land reclamation work.

Mega Man 2 Robot Masters

Roll

is a female robot designed for housekeeping instead of fighting. She is the younger female counterpart of Mega Man (formerly known as Rock, a pun on the term rock and roll), and plays a supporting role in the games. Roll first appears very briefly during the ending of the very first game of the series. Her name was never mentioned until Mega Man 3, marking her return, where her entry in Dr. Light's robot list is shown during the ending. It is likely that Mega Girl, in the cartoon, is Roll.

She is usually depicted in a red outfit with blonde hair. While she was not designed for fighting, she is a combatant in the fighting games, Marvel vs. Capcom and Marvel vs. Capcom 2. She fights similarly to Mega Man and has an external "Roll Buster." She also appears in the similar , where she uses a different moveset that revolves around house cleaning. She is also a playable character in Mega Man Powered Up, where she uses a broom as a default weapon with her skill, the Roll Swing, which she uses to swing a close range weapon that deals a large amount of damage. Roll can be played in several unlockable outfits, each with its own variation of the broom weapon. The version of Roll in Tatsunoko vs. Capcom appears to be based on the Mega Man Powered Up version.

Rush

is a robotic dog belonging to Mega Man. He is introduced in Mega Man 3, and has appeared in many games since. Created by Dr. Light and Dr. Wily to be an all around support unit, Rush has the ability to transform into various forms. Rush Marine transforms Rush into a small, one-seated submarine, and Rush Jet transforms his legs into jet engines that let him take flight. Rush also has the Rush Coil, which is a spring that pops out of his back and helps Mega Man reach higher platforms that he normally can't access. Other games have him transform into a motorcycle and a drill car, and in the fourth and fifth Gameboy games as a spaceship. In later games, the Rush Adaptor allows Rush to attach himself to Mega Man, allowing him to float, shoot more powerful blasts, and launch his arms as projectiles.

Tango

Tango is a robotic cat and one of Mega Man's allies. Tango can change itself into a buzzsaw and dive into enemies, until all in-area enemies are defeated or his energy is expended. Tango only appears in Mega Man V for the Game Boy, Rockman & Forte Mirai kara no Chōsensha for the WonderSwan and makes a cameo on Mega Man 10 in the item shop when playing with Proto Man. Like many other characters, Tango is also musical-themed.

Treble

is Bass' equivalent to Mega Man's dog, Rush. Like Rush, Treble can assume a jet-like form (as seen in Mega Man 8) and fly. After Bass stole designs for the Rush Adapter during the events of Mega Man 7, Treble has been able to transform into an armored suit for Bass, the "Treble Boost". This gives Bass limited flight capability and increased firepower. In Mega Man & Bass, the Treble Boost also grants Bass invulnerability while its energy lasts. The Treble Boost is also present in Mega Man 10, functioning similarly to its previous incarnation, but without the invulnerability. The name Treble continues the music theme of the original Japanese character names.
