Robot Master

Mega Man with the Robot Masters of Mega Man and Mega Man 2.

A Robot Master, also known as a Number (ナンバー) or often simply a Boss Character (ボスキャラ) in Japan, is a recurring term from the Classic era. It describes the unique humanoid robots who control the game's stages, being fought as bosses at the end of each. They are present on a game's Stage Select screen, and must be defeated to gain Special Weapons and open the Last Stages of the game. Many Robot Masters were designed by fans in official Boss Character Contests run by Capcom.

Both the terms "Robot Master" and "Number" have never been used in any video game's in-game dialogue, only in supplementary Capcom sources such as game manuals, strategy guides, and encyclopedias. "Robot Master" in particular was phased out of Capcom's English media by the release of Mega Man 7. Despite this, the term remains ubiquitous within the fandom and third-party media, such as Mega Man: Fully Charged and the Archie Mega Man comic, with varying definition.

Mainline Games

These Robot Masters are from video games endorsed as canon and referenced in the Mega Man: Robot Master Field Guide.

Robot Masters were introduced in the first Mega Man, though the term wasn't used until Mega Man 3 (these ones are retroactively called Robot Masters in Mega Man: The Wily Wars). The game has six bosses who are all industrial robots in the DLN (Dr. Light Numbers) series, or DRN (Dr. Right Numbers) in Japan. They were kidnapped by Dr. Wily and reprogrammed into his evil servants.

Time Man		Time Slow	DLN-00A DLN-010	Keiji Inafune
Oil Man		Oil Slider	DLN-00B DLN-009	Keiji Inafune

In the remake Mega Man Powered Up, two new bosses appear alongside the original six in New Style. The first Mega Man was originally planned with eight bosses, which was reduced to six during development. They are part of the DLN, but their exact numbering varies between early material for Mega Man Powered Up (Oil Man as DLN-009, Time Man as DLN-010) and the Archie Mega Man comics (Time Man as DLN-00A, Oil Man as DLN-00B).

In this game, all eight bosses can also be unlocked as playable characters in New Style. When playing as one, a copy of Mega Man called Mega Man? appears as the boss of their stage in their absence.

In Mega Man 2, the eight Robot Masters were created by Dr. Wily specifically to challenge Mega Man in combat. They are part of the DWN (Dr. Wily Numbers) series, though their numbering begins at the ninth entry, where the DLN from Mega Man left off.

This was the first game to call for submissions in a Boss Character Contest, allowing fans and staff alike to submit Robot Master designs for use in the game. These contests would be used for games until Mega Man 8.

In Mega Man 3, the eight Robot Masters were created together by Dr. Light and Dr. Wily, and are deployed to collect eight Energy Elements in space. Some Japanese sources list them as the DRWN (Dr. Right & Wily Numbers), though they are more commonly included as part of the DWN since Dr. Wily hijacks them for his evil gains.

In Mega Man 4, the eight Robot Masters were originally created by Dr. Cossack for a wide variety of purposes. However, when Dr. Wily blackmailed Dr. Cossack into challenging Mega Man, he also altered his creations into fighting robots and inducted them into his own DWN series. In the manga Mega Man Megamix, this group is instead listed as the DCN (Dr. Cossack Numbers).

In Mega Man 5, the eight Robot Masters were supposedly berserk robots led by Proto Man. In reality, they were all created by Dr. Wily and led by the impersonator Dark Man, in an attempt to frame Proto Man and conquer the world. They belong to the DWN. Dark Man is not part of the main eight bosses, and isn't normally included as a Robot Master.

They were then hijacked by the tournament organizer, Mr. X, who was later revealed to be Dr. Wily in disguise. They belong to the DWN. In the manga Mega Man Megamix, they are instead listed as the MXN (Mr. X Numbers).

In Mega Man V, the eight Robot Masters are a group of alien robots known as the Stardroids. They are led by Terra, who is manipulated into working with Dr. Wily to take over the planet. They belong to the SRN (Stardroid Numbers).

Another robot boss, Sunstar, is sometimes counted as a Robot Master. However, he serves as the game's final boss, and is not actually a member of the Stardroids.

In Mega Man 7, the eight bosses were all created or stolen and modified by Dr. Wily at some point prior to the end of Mega Man 6. Six months after Wily's imprisonment, they were activated to free him from jail and help conquer the world. They belong to the DWN.

This game was the first to avoid the term Robot Master in its English material. These bosses fulfill the same criteria as previous Robot Masters, and so are categorized as such.

Mega Man 8

Because Tengu Man and Astro Man return with new Special Weapons in Mega Man & Bass, their new Special Weapons are listed here as well.

Their ranks also include Tengu Man and Astro Man from Mega Man 8, whose data King stole and used to reconstruct them as his servants. Due to this, there are only six original boss robots in this game.

In Mega Man 10, the eight bosses are robots from around the world who went berserk after being infected by Dr. Wily's Roboenza. Though not personally altered by Wily, they are considered part of the DWN series. The bonus track in Rockman 10 Image Soundtrack, where Wily lists the Robot Masters and their abilities, implies that he chose these specific robots to make berserk.

They are led by Apollo and Luna, who seek to heal the god of their home planet but are manipulated by Dr. Wily into attacking the Earth. In the game, they are simply called "the aliens" (外星人). Lacking Special Weapons, the twelve alien robots each have one of four elemental alignments instead, directly corresponding to their sign's element in the Zodiac.

Additionally, many previous Robot Masters from Mega Man to Mega Man 8 appear as enemies alongside the game's bosses.
