This is a list of glitches and bugs in the Mega Man series, which are caused by programming errors. They may be harmless or hazardous. Some glitches are often exploited in Speed Runs, especially when tool-assisted.
Mega Man series
If the game is paused with the Select button, it is possible for Mega Man to avoid damage and make his attacks hit multiple times. This is most effective with the Thunder Beam, especially when fighting the Yellow Devil. This is because enemies' "invincibility timer" doesn't freeze when the game is paused, so waiting till it ends and then unpause causes the enemy to get hit again. It is important to note that this glitch was removed from later versions and ports of Mega Man, as the pause button gets disabled briefly during the timer in effect. It only works on the original NES game, Mega Man Anniversary Collection and Mega Man Legacy Collection.
Using the Magnet Beam in a specific way or another glitch causes Mega Man to zip through stages. Other glitches include being hit before entering the boss room.
At the final boss, if you get hit at the same time Wily Machine's first phase is defeated, pressing START repeatedly may cause Mega Man to constantly dart to the top-left part of the screen. You may end up in a glitchy corridor before the boss (as seen in the picture below). This can be done over and over again until Mega Man runs out of health.
If you land on the ground after the final hit on the second phase of the Wily Machine (easily done with Rolling Cutter) and walk to the left, you will be in the "anti-chamber" (as seen below) unable to move.
When using Guts Man, using the Super Arm on some bosses may leave them stuck in a pattern. This is most notably when facing Elec Man, as using Super Arm in the beginning of the battle will make him walk on the summoned block until it is removed, allowing for an easy victory.
A well known glitch in custom stages involve making custom boss rooms, involving placing the tiles along with a ladder in Construction mode in front of the boss door, with the boss room the creator want under the original boss room, jumping near the tiles and glitching through it into the original boss room, most of the time, the player and the boss will sink into the custom boss room. One can even have recovery items and enemies in the custom boss room.
When fighting a boss in his stage, touching the shutter may transport Mega Man to a glitched version of the
- Wily Stage 1 - Heat Man's stage, Bubble Lead
- Wily Stage 2 - Air Man's stage, Item-1
- Wily stage 3 - Wood Man's stage, Item-1
- Wily stage 4 - Bubble Man's stage, Item-1
- Introduction screen - Crash Man's stage, Item-1
Like the first game, a glitch can cause Mega Man to zip through stages.
By changing certain Special Weapons, it is possible to use them indefinitely, as their energy will not decrease. This is due to 1 unit in the gauge being less than 1 in the total. For example, Metal Blade, with full energy and without recharging, can be used a total of 112 times, 4 times per unit. Using it 3 times, changing to another weapon, and equipping it again will reset the unit to 4. This can also be done with Quick Boomerang and Bubble Lead.
In the beginning of Wily Stage 1, Item-3 can be used in the left corner despite the lack of a wall. It can also be used in a small area in the beginning of Wood Man's stage.
If Pierobot goes off-screen before landing and his gear doesn't disappear, it will move in the air.
If Time Stopper is used in a room with a Friender before it teleports in, Mega Man won't be able to pass the area it will appear as the game reads that it is already present. However, using Time Stopper before entering the room will allow Mega Man to pass as the Friender won't start teleporting.
Using the Leaf Shield to finish off a boss can cause it to stay out, and its sound drowns out part of the music. After reaching Stage Select, it will stop.
In the Mega Man Mobile port of the game, if Time Stopper is used near the end of Air Man's stage, there is a possibility that the weapon energy for it stays stuck and that the time stop stays on screen for the entire level, this will cause Air Man to glitch so the fight can't begin correctly.
Pausing the game when Wood Man jumps will make him move up further. By pausing continuously one can leave him away from the ground and defenseless.
In Wood Man's stage, if you follow a Atomic Chicken (in the area they spawn in) all the way to the left wall, they'll walk straight through the wall.
If you kill a Pierobot bouncing on its giant gear before it falls down (without destroying the gear), the gear will slowly fly around in air until it goes offscreen.
Sometimes, if you do these two things at the same time when an enemy hits you: (Shoot a non-charged Atomic Fire and tap LEFT or RIGHT), Mega Man's leg will glitch and appear to be made of Life Energy. This will only appear quickly.
Using the second controller may cause various effects, such as a super jump, invincibility (if Mega man collects energy item, he is no longer invincible though), and freeze the game.  This glitch was removed from the European version of the game and can only be done on the Japanese and US versions.
In Shadow Man's Doc Robot stage, on the second screen, sliding or jumping into the spikes, frames before the screen switches, the death noise plays, but the music stops. You can still complete the stage as normal. This can also be done on Spark Man's Doc Robot stage after defeating the Doc Robot imitating Metal Man.
In the pause menu, after obtaining the Shadow Blade or Spark Shock, highlighting the weapon and pressing the right button will respectively select the Rush Jet or Rush Marine, even if they were not obtained. By doing this, it is possible to use them earlier, but first they need to be recharged with Weapon Energy. To keep Rush Jet and/or Rush Marine permanently, Rush Jet/Marine must be used for at least 1 bar of energy, otherwise they will disappear from the menu. After clearing the stage, they will become available even if Needle Man and/or Shadow Man haven't been defeated yet. This cannot be done on the later ports or remakes of the game, with the exception of Mega Man Legacy Collection.
When entering a room that Proto Man appears, pause the game before landing on the floor to hear his whistle beyond the part it is interrupted.
In Gemini Man's stage, there is a large dome which Proto Man will destroy in order to let you continue. If Mega Man slides immediately before entering this screen and jumps as far as he can, he will fall through the dome and the Proto Man whistle will continue to play, eventually ending and the music remaining silent for the rest of the stage until Mega Man dies or enters the fight with Gemini Man. Some parts of the stage will have glitched graphics if this is done, notably the Penpen Makers.
Normally, if you slide through the shutters before a boss room, Mega Man will automatically start walking when the screen scrolls. If you slide into the shutter before Gamma, Mega Man will actually keep sliding. Mega Man would only be able to slide through shutters starting with Mega Man 5.
Occasionally, you can fire a weapon while entering a boss room. For example, firing a Magnet Missile while entering Shadow Man's room will cause the magnet to hit Shadow Man and bounce off, as Shadow Man is immune to this weapon (Though this doesn't seem to be the reason, as hitting Snake Man with a Mega Buster shot will do the same). Other weapons such as Hard Knuckle may go right through a boss without hitting it.
When using Top Spin against Shadow Man, the weapon energy may completely drain itself in a single hit. This also happens against Doc Robot (Crash Man), and against Top Man during the rematch. It does not seem to happen against Doc Robot (Heat Man). It also happens if an enemy is immune to Top Spin, for example Hammer Joe or the Cannons on Needle Man's stage. This glitch was fixed in Mega Man: The Wily Wars.
With a Rush item selected as the current weapon, you can normally fire two shots with the buster. Unlike normal shots, you can actually pause the game with these shots on-screen, and when resuming, the shots do not disappear unlike Mega Man 4 and later. If you switch weapons with the shots still on-screen, the shots gain the same attributes as the current weapon. For instance, selecting Top Spin will turn the buster shots into Top Spin buster shots, which carry the same weakness data as Top Spin itself e.g. destroying Gamma in one or two hits, or 7 damage against Shadow Man instead of 1, or merely bouncing off Hammer Joe who is immune to Top Spin. Note that Gamma is immune to the regular buster and the shots would normally bounce off, but the game actually thinks that you are firing Top Spin shots at him, not buster shots. This can be done with any Rush item, be it Rush Coil, Rush Marine or Rush Jet.
On the European version of the game, during the battle against Wily Machine 3 the floor constantly shakes up and down and glitched zeroes will appear in the floor. This is because Capcom did not alter the 60Hz timing of the game program for the 50Hz PAL console. If the same cartridge is used in an NTSC console (assuming the console has no regional lockout e.g. NES-101 Top-Loader), the glitch does not happen as the frame rate is correct for the game, however the sound effects and music will be higher pitched than normal.
Using Wire adapter in a scrolling stage causes Mega Man to slide and he launches up into the sky when he goes off of the platform. When near near the end of the scrolling section in Dr. Cossack's Citadel, Mega Man will be stuck.
If the Wire adapter is used to beat the boss of the third level of Dr. Cossack's Citadel player is still with wire adaptor still on, mega Man will fall on spikes without dying.
If Tako Trash is hit with Drill Bomb, Mega Man will be able to move through its body without taking damage. Also, even though Tako Trash is immune to Skull Barrier , after hitting him within Drill Bomb, he will then take 1 unit of damage from Skull Barrier.
After defeating the Wily Machine 4, Dr. Wily flies away in a machine. While he is going up, if you hit him with Rain Flush, he and his capsule will explode, "killing" him. Doing this will leave the player stuck in the room and unable to beat the game, requiring the player to reset the game.
Using Flash Stopper right before the victory sound will make all of the black colors in the background stay white. This also works before Mega Man lands to ground when encountering boss.When you select a weapon before Pharaoh Man's fight begins, it will cause his sprite to go weird. This works in the Mega Man Legacy Collection.
If player enters Skull Man's boss fight and uses Balloon, Skull Man won't move, although the player can move and shoot. Unfortunately, he cannot be harmed as well causing the player being unable to beat the game.
If the player uses Rush Marine in a short space, Mega Man will die when he enters Rush as it considers that he was crushed. Also, if Rush Marine is called in front of a high area, Rush may pass the floor and appear in the space available below.
In Wave Man's stage, using Super Arrow to jump over the Marine Bike will make Mega Man move on the water. He may get stuck in the area, but it is still possible to get the other side of the stage if the player stays on the screen.
In Gravity Man's stage, holding up and right when attempting to get to and climb the upside down ladder will result in Mega Man constantly seeming to jump and glitch around in the air. This glitch is not harmful.
Also, in Gravity Man's stage, spamming left and right in a gravity changer when a enemy which is affected by gravity, there is a chance that the enemies' gravity will flip.
Using Noise Crush just before entering the boss room may cause it to hit the boss, instantly killing him if timed right. This works primarily with Spring Man and Turbo Man. Doing so with Cloud Man (done with Danger Wrap instead) causes the room to glitch out and eventually kills Mega Man.
If Tengu Man is defeated while Mega Man is stuck in his air sphere, the player will be able to move after his explosion. If the player falls in one of the pits after taking the Evil Energy, Mega Man will return to the checkpoint and Tengu Man must be defeated again.
If you press a button on the D-Pad at the same time when you select a Robot Master, if timed correctly, the Robot Master will jump towards the center as parts of the background move up and down endlessly. The Robot Master's name will not appear, and the stage will never start, forcing you to reset.
Metal Man may get stuck on walls.
If you use Hard Knuckle right before transitioning the screen down, it may cause strange effects if timed correctly.
When you first reach the checkpoint in Crash Man's stage (with the mountains in the background), there is a ladder to the left that you climbed to get there. If you go off-screen and come back, there will suddenly be Tellies spawning next to the ladder.
There is a glitch that allows the Black Hole to damage and defeat the first form of the Brain Crusher by using it at point blank range. If the first form is defeated this way, the game will cut straight to the cutscene preceding Sunstar, skipping the Brain Crusher's second form.
If you pause and unpause when you touch the boss door, the door may still appear partially opened as you walk through it.
You can get a Nuclear Detonator to get stuck in a wall if you simply stand right in front of a wall and fire it, as shown in the picture to the right. You can also get a Sonic Wave stuck in a wall. It will bounce a few times inside the wall very quickly before disappearing.
Mega Man X series
Although the player is not supposed to die against Vile with a Ride Armor, as he will try to capture X when his health is low, dodging his capture beam and getting contact damage will eventually result in X's death. Also, if X and the last Road Attacker kill each other, Vile will still appear and grab an invisible X.
In Storm Eagle's stage, using Boomerang Cutter on the Life Up and dashing to the right to catch it while falling may cause a platform to appear on the Boomerang Cutter. The timing is difficult, but when well used, this platform can be used like a magic carpet, flying the player to the end of the stage. Doing this will also cause several errors, like a glitched background and invisible enemies.
Shotgun Ice can be used to glitch in walls and skip the rematch against Armored Armadillo in Sigma's fortress. If you jump to make Armored Armadillo appear, he'll look glitched, but you can continue the stage like normal while the boss theme is playing, without killing him still.
If passwords are used to finish the game without the Foot Parts (which can't be avoided normally), X will have the Foot Parts in the scene showing Sigma's fortress collapsing, and his legs will vanish when he does a dash in the ending.
On the remake, in Armored Armadillo's stage, reaching the boss door while stepping on the right tip from the last mobile platform, it can make X get stuck in a walking animation without moving to the next room, making impossible to continue unless the player exit the stage/restart the game.
In the final stage, when X reaches the room where Chop Register was fought and uses the Shoryuken at a certain distance, he may end up in the centre of the room during the following cutscene. If the player obtained all three of Zero's pieces, X will immediately fall through when Zero punches the hole in the floor, although Zero will continue with his dialogue. If the player does not close the dialogue box, Sigma's pre-fight dialogue will eventually override Zero's and when it closes, the player regains control of X earlier than they're supposed to. If the player preforms a Shoryuken while Sigma's life meter is filling up, X will become invincible during the fight until he preforms another Shoryuken or reaches Sigma's viral form in the second half of the fight.
Using Giga Crush while on a ladder will result in a glitch.
In Wire Sponge's stage, when the player makes it to the first set of floating platforms and jump up to where is an 1-UP, switching to either X or Zero will cause the 1-UP to turn blue or red. Zero's 1-UP turns blue while X's 1-UP turns red. It's a harmless glitch and it will still function as a 1-UP.
Mega Man Zero series
Mega Man Legends series
The PC version contains several bugs.
Unequipping the Blade Arm during the jumping slash will make Mega Man walk in the air until he jumps or is attacked.
The PC version contains several bugs.
In Gold City, forcing a NPC to move to the mountain will leave him stuck in the air.
Mega Man Battle Network series
If MegaMan.EXE is far from the enemy in a battle, normally the Mega Buster fires slowly, while it fires faster the closer he is to the target. However, the player can increase the speed by "step buffering" which is constantly moving and shooting to cancel out the rest of the buster animation.
When using the chip trader, you can save before inserting your chips and soft reset the game if you do not get a chip you want. Capcom fixed this in the later games by requiring you to save when you insert chips.
Unfortunately, this one isn't as pleasant as the others. When Woodman's scenario is triggered (the event with the wooden stakes popping up through the ground), when a virus battle is concluded in any way, the game will experience massive slowdown until Megaman jacks out. Since it triggers by entering and concluding a battle, that means you can use sneakrun to avoid the glitch. This mainly occurs when playing on the Nintendo DS, but some people have claimed to experience the glitch when playing on a Gameboy Advance or on an emulator. This glitch was fixed in the Wii U Virtual Console re-release.
