Big Eye

Big Eye (ビッグアイ) is a one-eyed surveillance robot with high defense that tries to crush its enemies. A single Big Eye appears in the stages of Cut Man (red), Guts Man (blue), Ice Man and Elec Man (red), and three gold Big Eyes appear in the beginning of the final stage. They also appear in first part of Wily Tower in Mega Man: The Wily Wars. In Mega Man Powered Up, the intro stage boss is a larger Big Eye called Proto Eye that attacks with laser orbs and stomps.

Big Eyes are vulnerable on all parts of their body except in Mega Man Powered Up, where the only weak spot is the eye, which closes when at rest. In Mega Man: Dr. Wily's Revenge, Big Eyes can only be damaged while they are jumping and appear in the stages of Cut Man, Ice Man, Elec Man and both Wily stages (Wily fortress and Wily station respectively). They are weak against Super Arm and Thunder Beam. Although Big Eyes aren't damaged by Ice Slasher, they will be frozen, making fighting or passing by them significantly easier. It is best to freeze them at the peak of their high jump so Mega Man can walk underneath it safely. If the player jumps just before a Big Eye does, it will always do a higher jump.

Proto Eye
Proto Eye (プロトアイ) is the boss from the introductory stage of Mega Man Powered Up. It is a larger version of a normal Big Eye and is grey. It can attack with laser orbs, and how many it shoots depends on the games difficulty setting. The Proto Eye is actually less dangerous than a regular Big Eye, since it deals less damage, is vulnerable on all parts of its body, and makes slower, wider jumps all at the same height, although this is understandable since it is merely an introductory boss for beginners to learn the basics on.

Big Eye in the Battle Network series
BigEyes appear as viruses in Mega Man Network Transmission. They act basically the same as the original enemies.
