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.

Mega Man
If the game is paused with the Select button, it is possible to Mega Man avoid damage and make his attacks hit multiple times. This is most effect with the Thunder Beam, specially when fighting the Yellow Devil.

A glitch causes Mega Man to zip through stages.

And others, like being hit before entering the boss room.

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

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 equiping 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.

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.

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 posible to hit Cloud Man with Danger Wrap, causing several errors.

Mega Man 8
