Glitches

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
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. It is important to note that this glitch was removed from later versions and ports of Mega Man. It only works on the original NES game.

Using 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, put Wily's Ship's Health to 1 bar. then get hit and shoot the cannon at the same time. Rapidly press start. Mega Man Darts to the upper left of the screen. Keep doing this until the screen changes. You can do this over and over again until you run out of health.

Mega Man Powered Up
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.

Mega Man 2
When fighting a boss in his stage, touching the shutter may transport Mega Man to a glitched version of the Wily Stages.
 * 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 other 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.

If Pierobot goes offscreen before landing and his gear doesn't disappear, it will move in the air.

Keep Pressing Start when Wood Man Jumps. If done right, he flies.

Mega Man 3
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.

In the pause menu, after obtaining the Shadow Blade or Spark Shot, 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.

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.

Mega Man 4
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 you defeat the final boss, Dr. Wily flies in a UFO out of the Castle. While he is going up, Use Rain Flush immediately to kill him. WARNING - You will not beat the game if you do this.

Use Flash Stopper Right Before the Victory Sound. All of the black colors in the background stays white.

In the part where the pistons are in Dust Man's stage, Shoot at the blocks for the Metall EX. Make sure its high. Let it go in the spot of blocks. If done right, Metall EX floats in the air.

Mega Man 5
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.

Mega Man 6
Although difficult, it is possible to slide in the air to pass the Count Bombs before the boss room in Blizzard Man's stage.

Mega Man 7
Using Noise Crush just before entering the boss room may cause it to hit the boss, instantly killing him if timed right. It is also possible to hit Cloud Man with Danger Wrap, causing several errors.

Mega Man 8
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.

Mega Man & Bass
By using Lightning Bolt, the player can avoid the Monking A scene in King Stage 1. Also, Ice Wall can interfere with the scene.

Mega Man II
Metal Man may get stuck on walls.

In Metal Man's Stage, Mega Man may receive damage for no apparent reason in one area. This is due to Moles appearing beyond the point they are supposed to.

Mega Man X2
Using Shoryuken before the sub-boss in Magna Centipede's stage will activate the Zero/Black Zero scene and following events.

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.
