This is a list of characters in the Mega Man series.

Concept and creation According to artist and producer Keiji Inafune, Dr Wily's name and design are inspired by Albert Einstein, and he was initially conceived to appear as a tall, thin scientist with a mustache, glasses, balding hair, and lab coat. As development on Mega Man progressed, Inafune redrew Wily to match the in-game sprites, making him shorter and removing the glasses from his design. Inafune has expressed disdain for this design, stating in a 2003 interview that if an artist approached him with similar work, he would reject it and demand better. With the production of Mega Man 2, Inafune decided to redraw Wily's design completely, aiming to tie into the common perception of a mad scientist. After making his design slightly taller and with elongated hair and chin, Inafune was satisfied with the alternations and kept the design consistent for later appearances of the character. Since the beginning of the Mega Man X series, Inafune wanted to add Dr. Wily to the story, leading to Mega Man X4 revealing that he created Zero to set the climax of the series. Wily often is shown moving his eyebrows up and down when he appears in most of the games, usually seen in the prologue cutscenes to the castle levels.

For Proto Man, Inafune wanted people to be unsure whether Proto Man was a friend or a foe. Several anime characters Inafune used to watch inspired Proto Man, with the glow from his eyes being inspired by Break Man. The design also involved his shield being a "cool factor" and a sign of his superiority over Mega Man. Higurashi considers Proto Man and Rush to be the main attractions of Mega Man 3, while Hideki considers Mega Man 5 as a "Blue"'s Trap, resulting in major focus when making illustrations focusing on him. For Mega Man 8, Kaji had difficulties in making the illustrations, leading Inafune to revise the ones from Proto Man.

Since the release of Mega Man, numerous characters have appeared across the series.

Main characters Mega Man

DLN-001 Mega Man, known in Japan as is the main protagonist of the original Mega Man series. Dr. Light originally created him to be a lab assistant named Rock, but he was modified for combat after Dr. Wily reprogrammed the original Robot Masters to take over the world. His Variable Weapons System allows him to copy the weapons of other Robot Masters and use them as his own.

Doctor Thomas Light, known in Japan as , is a scientist and roboticist and the creator of Mega Man and several other robots, such as his Robot Masters, and he considers them his own children; as such, he can be considered the father of Mega Man, Roll, and Proto Man. Dr. Light is an idealist with a big heart, but he's naive and gullible at times, especially when it's about his rival, Dr. Wily. Despite being a pacifist and disliking violence, he reluctantly recognizes that using force can sometimes be necessary. He plays a supporting role throughout the series, often developing new equipment to help Mega Man in his battles. He died prior to the events of the Mega Man X series, which is set 100 years after the original series, but his legacy continues through his last creation, X, and he maintains a supporting role through enhancement capsules that contain upgrades to X's systems along with messages relayed by holographic projections of him. He also appears in the "Navi Mode" of Mega Man and Mega Man 6 in the Mega Man Anniversary Collection to provide gameplay hints to Mega Man.

Dr. Wily Voiced by (English): Ian James Corlett (Captain N: The Game Master), Scott McNeil (90s TV series), Dean Galloway (Mega Man Powered Up), Keith Silverstein (Mega Man 11)

is a mad scientist and the main antagonist of the series. He was Dr. Light's colleague when they were university students; driven by jealousy towards Light and his achievements overshadowing his own, he reprogrammed Light's robots, except for Rock and Roll, to assist him in taking over the world. However, Rock, who was upgraded and became known as Mega Man, defeated him. Wily returns as antagonist in subsequent titles of the main series, each time with a different scheme, only to ultimately be defeated and surrender to Mega Man.

Wily has also played a major role in the backgrounds of other characters in the series. He repaired the prototype for Mega Man, Proto Man, and in Mega Man 7 used the knowledge he gained from the process to create his answer to Light's work, Bass. After Bass proved to be unreliable, Wily refined his design, creating Zero, who, in the Mega Man X and Mega Man Zero games, is a hero working alongside Light's last creation, X. Though Wily died prior to the events of the Mega Man X series, his legacy continues through a virus which Zero initially carries and is later transferred to Sigma, resulting in the creation of the Sigma Virus and most of the Mavericks.Capcom staff (5 September 2008).

GamesRadar praised that "Dr. Wily brings a certain flair to his evil schemes". IGN praised Dr. Wily as a "hopelessly persistent" video game villain, who returned despite his failure at the ending of each Mega Man game, concluding that "in a realm dominated by forgettable villains, Dr. Wily's staying power is a true testament to both his fictional tenacity and his popularity amongst gamers since the 8-bit days of the 1980s." Destructoid editor Chris Carter attributed the appeal of the character in part to the recurring grovelling of Dr. Wily after each defeat, allowing the player to "revel in your enemy's defeat", and considered this trait "as iconic as it is an in-joke".

DLN-000 Proto Man, known in Japan as , was the prototype of the robot master, and Mega Man's older teenage brother. He first appeared in Mega Man 3 under the name Break Man working for Wily (albeit disloyally). However, at the end of Mega Man 2: The Power Fighters, Dr. Light reveals that Proto Man's energy system has a fatal defect, causing him great pain and shortening his lifespan. He also appears in the "Navi Mode" of Mega Man 3 in the Mega Man Anniversary Collection to provide gameplay hints to Mega Man.

The absence of Proto Man in Mega Man 11 has been criticized. Mega Man 11 producer Kazuhiro Tsuchiya explained his exclusion in the game, stating that "What we struggled with the most was how to develop a clear and engaging story that builds upon the previous installments while appealing to a wide range of players; new players picking up a Mega Man game for the first time, those who may have forgotten the series' backstory, and the hardcore fans who remember the events of 9 and 10 as though they happened yesterday. After the long gap between 10 and 11, we decided to focus on sharing an untold story that touches on the past of Dr. Light and Dr. Wily."

Bass Voiced by (Japanese): Keiko Nemoto (X DiVE)

SWN-001 Bass, known in Japan as , is a robot Dr. Wily designed, who was constructed based on research conducted on Mega Man with the intention of matching his power, being a more advanced model of Robot Master compared to Mega Man. He is powered by the energy Bassnium, the most powerful form of energy on Earth, which Wily discovered by mistake. He seeks to defeat Mega Man and be acknowledged as the world's strongest robot, and as such frequently rebels against Wily when he feels he is standing in the way of his goals. Despite this, Bass has worked with Mega Man several times, though usually for his own purposes.

Bass wields the Bass Buster, which originally functioned similarly to the Mega Buster, albeit with slightly different shots. As of Mega Man & Bass, however, it has lost its ability to charge shots in favor of an increased rate of fire and the ability to fire upwards and diagonally. Unlike the Mega Buster, its bullets do not travel through solid surfaces without equpping a specific upgrade. Like Mega Man and Proto Man, Bass can also copy the weapons of Robot Masters, with his body changing colors to reflect the weapon currently equipped. He can also combine with his robotic wolf for the Treble Boost, allowing him to fly and shoot more powerful projectiles from the Buster.

He is playable in Mega Man 10, being added through DLC, where he retains his dash and rapid-fire, multi-directional arm cannon. In the game's re-release as part of Mega Man Legacy Collection 2, Bass is instead unlocked by either completing the game or by using a secret code at the title screen.Mega Man Legacy Collection 2 is available now! -Capcom Unity

In Mega Man 2: The Power Fighters, where Zero makes a cameo appearance, Bass seeks to destroy him to prove that he is stronger than all other robots, as Wily says that he is a creation that could surpass him.

Roll Voiced by (English): Robyn Ross (90s TV series), Angie Beers (Mega Man Powered Up), Erica Lindbeck (Mega Man 11)

is Mega Man's younger "sister"; a female robot designed for housekeeping instead of fighting. She plays a supporting role in the first game and a more substantive role in subsequent sequels. Her name was never mentioned until Mega Man 3, which marks her return, where her entry in Dr. Light's robot list is shown during the ending. She also appears in the "Navi Mode" of Mega Man 2 in the Mega Man Anniversary Collection to provide gameplay hints to Mega Man.

She is usually depicted with blonde hair worn in a ponytail and wearing a red dress and mary janes. In Mega Man 8, she wears a black and red dress with red boots and a green ribbon in her hair. Despite not being designed for fighting, she appears as a combatant in the fighting games Marvel vs. Capcom, Marvel vs. Capcom 2, and Tatsunoko vs. Capcom, as well as in Mega Man Powered Up. Alternate versions of Roll appear in two other Mega Man spinoff series: Roll Caskett in Mega Man Legends, and Roll.EXE in Mega Man Battle Network. Roll also appears in other Mega Man media, including manga and the Mega Man TV series.

Rush is Mega Man's robotic dog and sidekick. He was created by Dr. Light to be an all-around support unit and is first introduced in Mega Man 3. He can transform into various forms, including Rush Marine, which transforms him into a one-seated submarine, and Rush Jet, which transforms his legs into jet engines that allow him to fly. He also has the Rush Coil, a spring that pops out of his back and helps Mega Man reach higher platforms that he normally cannot access. Other games have him transform into a motorcycle and a drill car, and in the fourth and fifth Game Boy games as a spaceship. In later games, the Rush Adaptor allows Rush to attach himself to Mega Man and merge with him by using specific adaptors, allowing him to float, shoot more powerful blasts, and launch his arms as projectiles. In some games, such as Mega Man 7 and Mega Man 8, Rush can be used to obtain items, such as health. His name is derived from another Capcom game, The Speed Rumbler, which is known as Rush & Crash in Japan, while the pronunciation of his name is similar to Lassie.
