The Doc Robot K-176 (ドクロボットK-176 Dokurobotto K-176) is an all-purpose robot from Mega Man 3. He comes with a number of different attachments and devices on his body that can use the same abilities of other robots by switching his program data.[1] After defeating the eight Robot Masters, Mega Man faces Doc Robot eight times when revisiting Needle Man's stage, Gemini Man's stage, Spark Man's stage, and Shadow Man's stage. When selecting Doc Robot in the stage selection screen, it will be introduced with a question mark in the character introduction. On each battle, Doc Robot utilizes the program data of one of Dr. Wily's eight Robot Masters from Mega Man 2.


Since the Doc Robot copies the ability and characteristics of one of the eight Robot Masters from Mega Man 2, the Doc Robot's strategies are similar. However, the player should keep in mind that the Doc Robots have a larger hitbox than the original Robot Masters whose data they copy for their weapons, and also have some differences from the originals that make Doc Robot a more powerful version of those bosses.

Metal Man[]

The battle against the Doc Robot with Metal Man's data is somehow easier than the original Metal Man fight, as there's no conveyor belt on the floor. With nothing to distract the player from dodging the Metal Blades, it is much easier to focus on projectiles. Doc Robot does shoot Metal Blades at a faster rate, likely because of the lack of a telegraph animation. Doc Robot's 'timer' of attacking on his own also does not reset when he jumps at the player's command, meaning he can now just attack all of a sudden.

The Metal Man Doc Robot shares the same weaknesses as Hard Man: Magnet Missile and Hard Knuckle, both of which will kill him in 7 hits. Both weapons are viable to use as the former will lock onto him when he jumps in place, and the latter's slow speed will eventually hit him once he lands.

Air Man[]

The attack pattern from the Doc Robot with Air Man data functions pretty much the same as Air Man's did before. However, the tornadoes have increased hitboxes which makes them even harder to dodge, and it doesn't help that the frame-perfect patterns have returned as well. The 'wind-blowing' acceleration is also dramatically slower as it severely lags the game. Sliding can be used to avoid some of his tornadoes.

The Air Man Doc Robot shares the same weaknesses as Magnet Man: Spark Shock and Magnet Missile, both of which will kill him in 7 hits. As Spark Shock costs less ammo, it is the more optimal weapon to use. Doc Robot also still takes 2 damage from the Mega Buster.

Bubble Man[]

The Bubble Man Doc Robot's arena is the same as Bubble Man's, and his attack pattern is pretty similar but has some minor differences. Doc Robot will now start swimming forward after he is done shooting his last Bubble Lead, whereas Bubble Man previously would start swimming immediately once the last Bubble Lead is fired. Doc Robot's projectiles are also faster in speed, which make them a lot harder to dodge if you get caught in the crosshair.

The Bubble Man Doc Robot shares the same weaknesses as Spark Man: Spark Shock and Shadow Blade, with both killing him in 7 hits. The former has more range while the latter has more aim, so it's up to the player to choose which one will do the job.

Lastly, there is a major exploit that can be taken advantage of. When Doc Robot lands, he will not start his next attack pattern cycle until the player lands back on the ground. Using this knowledge, the player can get on Rush Marine/Jet, stay above the ground when Doc Robot lands, and then unleash rapid-fire on him. If done correctly, the boss will not move as he is still waiting for the player to touch back on the ground, guaranteeing victory. Bubble Man himself also followed this rule, but there was no utility like Rush that could actually exploit it in Mega Man 2.

Quick Man[]

The Doc Robot with Quick Man's data has been amplified in difficulty to be more extreme, making for one of the hardest Doc Robot battles. Although the wall-clipping bug has been removed, Doc Robot is purely random with his jumps. He can do 1-3 jumps before walking forward, and even though the specific amount cannot be decided in the heat of battle, his jump arcs are the same as before. However, it is much harder to jump over him thanks to his size. The Quick Boomerangs are always thrown regardless of the current jump count. Keeping this in mind, there's a rare change that the fight can start with the player taking forced damage if Doc Robot does a short jump and immediately throws Quick Boomerangs. This is also one of the 2 fights where damage values have been modified: in this case, contact damage has been strengthened to kill you in 4 hits, while Quick Boomerangs has been weakened. Tanking those boomerangs should be prioritized as much as possible because of how much contact damage the boss can do.

The Quick Man Doc Robot shares the same weaknesses as Gemini Man: Search Snake and Gemini Laser, with both killing him in 7 hits. Due to Doc Robot's quickness, both of these weapons are very difficult to use consistently, as Search Snake is a close-range weapon and Gemini Laser can only have one shot onscreen. It should be noted that unlike the original fight, Doc Robot takes 1 damage from the Mega Buster.

Crash Man[]

The Crash Man Doc Robot's attack pattern is beefed up slightly from before. As the player can now slide, the Crash Bombs are now aimed at places where the player is anticipated to go, like in front of the player or above the player's head. Doc Robot's 'timer' of attacking on his own does not reset when he jumps at the player's command, meaning he can now just attack all of a sudden. Doc Robot's bigger hitbox also means he is much harder to jump over.

The Crash Man Doc Robot shares the same weaknesses as Top Man: Hard Knuckle and Top Spin, with the former killing him in 4 hits and the latter in 7. Obviously, Hard Knuckle is the better choice here. It should be noted that unlike Crash Man, Doc Robot takes 2 damage from the Mega Buster.

Flash Man[]

The battle against the Doc Robot with Flash Man's data is much harder than Flash Man. His arena is now a large hill that peaks at the middle. The pattern is similar to before, but the boss has a much bigger hitbox that makes jumping over him extremely tight and down-right impossible if he's walking onto Mega Man from above (Rush is required to get over him without getting hurt at the start of the battle). Doc Robot does not jump towards the player if he gets hurt, but his Time Stopper cooldown has decreased significantly. Due to a bug, getting hit by one of the Time Stopper shots may reduce the time of the player's invincibility frame duration, meaning that the player can possibly get hit more than once by a single Time Stopper barrage.

The Flash Man Doc Robot shares the same weaknesses as Needle Man: Gemini Laser and Needle Cannon, both of which will kill him in 7 hits. Needle Cannon costs less ammo and can continuously hit him, but Gemini Laser has the advantage of still hitting Doc Robot when he uses Time Stopper, as weapons do not get frozen by the attack. It should be noted that unlike Flash Man, Doc Robot takes 1 damage from the Mega Buster.

Heat Man[]

The Heat Man Doc Robot is more or less the same as the original. The biggest difference is how the Atomic Fires are shot out, which is more noticeable at the beginning. At the start, the player now has to slide and short hop through the flames, rather than just jump. Doc Robot still "dings" off shots when he sets himself on fire, but no longer "dings" when charging forward. This is also one of the two fights where damage values have been modified: in this case, all attacks do the same damage of 4, making punishment from getting hit by the charge less extreme.

The Heat Man Doc Robot shares the same weaknesses as Shadow Man: Top Spin and Shadow Blade, with the former killing him in 4 hits and the latter killing him in 7 hits. The former is actually a viable choice only if the player has the health to utilize it, and the way the pattern is structured means the player shouldn't worry about losing all of their ammo. The latter is a bit weaker, though if the player throws a Shadow Blade forward as soon as they jump over the charge, the weapon should boomerang back and hit Doc Robot once he comes out of the charge and before he can throw Atomic Fires. It should be noted that unlike the original Heat Man fight, Doc Robot takes 1 damage from the Mega Buster.

Wood Man[]

The battle against the Doc Robot with Wood Man's data is a lot more difficult than the original. Thanks to his size, the Leaf Shield he creates is bigger in diameter and now impossible to shoot through when up close. The leaves that sway down from above are slower and easier to dodge on their own. However, Doc Robot throws the Leaf Shield forward when the leaves have been onscreen for about a full second. This means the player not only has to jump over the Leaf Shield (the jump being much tighter because of the shield's size) and somehow dodge the leaves mid-jump at the same time. Doc Robot also jumps much farther, being able to fully corner the player after two jumps.

The Wood Man Doc Robot shares the same weaknesses as Snake Man: Needle Cannon and Search Snake, both of which will kill him in 7 hits. Arguably, the former is better as it can hit the boss sooner and rapid-fire to deal as much damage as possible within the short timeframe. It should also be noted that the Leaf Shield actually can be shot through only when it is flying forward.

Captain N: The Game Master[]

A different "Doc Robot" appears in Captain N: The Game Master. This one is a small and thin doctor robot with glasses and beard that assists Dr. Wily (a literal "Doc" Robot). He only uses Metal Man's Metal Blades to attack, and was smashed by a giant pipe that he cut with one.

Mega Man (Archie Comics)[]

Doc robot appears

Doc Robot in Mega Man #44.

The Doc Robot (designated as Diverse Operations Circuit Robot) is seen being constructed by Dr. Light and Dr. Wily in issue 36. Dr. Light and, officially, Dr. Wily, see him as a way to test multiple Robot Master systems at once as an economic alternative to building a single specific Robot Master from scratch. Privately, however, Wily, unsurprisingly, views the Doc Robot as a trump card against Mega Man due to the failure of his individual Robot Masters and Copy Robot. Rock and Roll, when learning of the nature of the development, noted the Doc Robot's use about being more dangerous than Mega Man, resulting in an argument between Wily and Rock. The Doc Robot is also given a brief mention in issue 38, where Dr. Wily privately remarked that he still has one ace up his sleeve, even if Mega Man managed to escape his trap in the mesa and even if he managed to take down all eight of the third generation of Robot Masters before Dr. Light interrupted. During this instance, the Doc Robot can also be seen obscured in shadow behind Wily.

In issue 42, Break Man collects the I.C. chips and weapon data of the eight Mega Man 2 Robot Masters so that Doc Robot can use them against Mega Man. Wily is still working on him in issue 43, and is eventually fully activated in issue 44 despite a security lockdown, as a result of Break Man being cleared for access to Light Labs. Upon being completed by Wily and Break Man, the Doc Robot joins them in confronting Dr. Light and Roll, telling the doctor (with two voices) to not be troubled as they will be quick. In Issue 45, they proceeded to cause a blaze, and asked in multiple voices whether he should fan the flames that are already present, or blow more things up. After learning Mega Man had arrived, he demanded to let Mega Man come as they can handle him effortlessly. However, he was hit by Roll's broomstick, causing him to retaliate (although with some reluctance since she is a kid and a helper robot), hitting her with Air Shooter and then narrowly missing with Bubble Lead after Dr. Light pushed her out of the way. It is also explained that the Doc Robot's multiple voices and his random attack patterns were a glitch as a side effect due to all the second-generation Robot Masters' IC chips being forcibly implanted into his body, as he was supposed to test only one chip at a time and the personalities of all eight were active within his body.

The Doc Robot later forcibly separated Dr. Light from Wily after the former attacked the latter after he was pushed past his limit, and proceeded to blow up the upper portion of Dr. Light's lab on Wily's orders. In the next issue, the Doc Robot interrupted Dr. Wily's progress in achieving total synchronization with Gamma to inform him that Mega Man had arrived at Wily Castle, also notifying him that Mega Man most likely learned the location from Break Man, as the latter had leaked the access codes to Mega Man to have a final battle with him. After watching their battle for a while, Dr. Wily orders that the Doc Robot prepares the defenses while he continues working on Gamma.

After Mega Man defeats the Copy Robot and tries to convince him to stop fighting, the Doc Robot fires a Crash Bomb on the copy's back. Before exploding, the copy pushed Mega Man away to save him. Mega Man realizes that the Doc Robot has Wily's first eight robots inside, and manages to defeat him by causing the robot to overload from his multiple personalities. In "his" final words, the Doc Robot asked Mega Man to have them rebuilt after he defeated Wily, which he promised to do before blasting off Doc Robot's head and copying the weapons he had employed against him.

While in the Doc Robot, each robot had a color in their speech balloon identifying who is speaking:

Mega Man Megamix[]

The Doc Robot is a versatile and powerful combat robot made with a system able to support any type program. Wily originally planned to mass produce this robot in his quest for domination, but the Doc Robot's many qualities made the production cost quite high, allowing Wily to build only eight Doc Robots. By using the combat program from the first eight Wily Numbers, the Doc Robots can be effective on various situations such as aerial battles, land battles, underwater battles, etc, even with the same frame. Unlike the Numbers, the Doc Robots have no individualilty, being closer to Sniper Joes in that regard.[2]

A Doc Robot has a cameo appearance as one of the robots fought by Mega Man in New Metropolis.

In Mega Man Gigamix, Doc Robots appears in the story Asteroid Blues, which is based on the events of Mega Man 3. They help Dr. Wily retrieve the Energy Crystal sample stored back on Earth.



  • The Doc Robot's Japanese name, "dokurobotto", is actually the combination of two words: "dokuro", (which means "skull") and "robotto" (which means "robot"). The name basically translates to "skull robot", which coincides with the motif of Dr. Wily building skull-based contraptions and robots; however, the meaning was lost in translation and resulted in the name "Doc Robot".
    • As a result of this, in Captain N: The Game Master, the Doc Robot appears as a helper robotic doctor with a humanoid appearance.
    • Though both interpretations hold different cultural interpretations, the Doc Robot's basis is most similar to that of The Monster created by Doctor Frankenstein of the famous novel Frankenstein's Monster by Mary Shelley, as the Doc Robot makes the use of other past Robot Master's weapons.
  • The devices seen attached to Doc Robot at various places are what may be a buster on his right arm, a Quick Boomerang launcher on his left wrist, and a copy of Bubble Man's Bubble Lead and Crash Man's Crash Bomber module on his back.
  • The Doc Robot is one of the few copy-characters in the Mega Man franchise who not only can copy and use the abilities/weapons/movesets of another, but does not change shape or color to the person they are mimicking while doing so.
    • In Mega Man 3, however, when the Doc Robot copies Metal Man's moveset, the Metal Blades appear orange instead of their regular coloration. This was corrected only in Mega Man: The Wily Wars.
  • The Doc Robot is the first Robot Master without a serial number to appear in a Mega Man-related cartoon. The second one is Dark Man.
