Shield Attacker

Shield Attacker (シールドアタッカー) is a recurring flying enemy that is indestructible in front. It can only be damaged attacking his back or attacking him with some of the special weapons. They first made an appearance in Mega Man 4. In Mega Man 7, they flip their shield face rather than turning around. In Mega Man 8, they are modeled after the Oni Mask boss from Mega Man 7, HannyaNED².

Shield Attacker
Shield Attacker is an enemy from Mega Man 4 and Mega Man III. It appears in Dust Man and Skull Man's stages in Mega Man 4 and Mega Man III, the fourth stage from Dr. Cossack's Citadel and the third Wily Castle stage in Mega Man 4, and in Drill Man's stage and the Wily Station in Mega Man III. Through it is weak to Drill Bomb, Ring Boomerang is also a good choice against it, as it can pass its armor. Rain Flush destroys Shield Attackers instantly, although it uses a lot of energy, so it's best to use in areas with large amounts of enemies, such as the extra section containing the E-Tank in Skull Man's stage. Flash Stopper negates the shields of the Shield Attacker, but like Rain Flush it uses a large amount of energy so it is best to use it when incoming Shield Attackers cannot be avoided.

Shield Guard
Shield Guard, known as Shield Attacker in Japan, is a version from Mega Man: Powered Up that has a propeller instead of jet engine, making them slower. Their shields can be knocked out by some attacks. They appear in Time Man's stage and Ice Man's stage.

New Shield Attacker
New Shield Attacker (新シールドアタッカー) is the Shield Attacker with an improved armor that appears in Mega Man 5. It only appears in Crystal Man's stage. They are immune to Gravity Hold. As the area in which they appear in has a high ceiling, they can be avoided by sliding or jumping over them and waiting for them to fly off the screen.

Shield Attacker GTR
Shield Attacker GTR (シールドアタッカーＧＴＲ) is an upgrade of the Shield Attacker that appears in Mega Man 6. It is the third type of Shield Attackers. It now has spikes on its shield. It appears in Blizzard Man's stage, Tomahawk Man's stage, the fourth section of Mr. X's Castle and the second section of Wily Castle.

Yamato Spear and the fully-charged Rush Power Adaptor ignores the shields of the Shield Attacker GTR, while Knight Crush and Silver Tomahawk fired at the correct angle will also hit the Shield Attacker GTR from below and therefore ignores the shield. A similar strategy can be applied to Flame Blast - if a wall of fire is raised directly in front of a Shield Attacker GTR, once they run over the flame pillar they will take damage - the Plant Barrier's energy petals can also slip beneat the shield and do damage in the same manner. Shield Attacker GTRs are immune to Beat.
