Sniper Joe

Sniper Joe fights with a shield and a blaster and also operate many robotic attack vehicles. They appear in many colors (green in Mega Man 1 and most other Mega Man games, orange in Mega Man 2 and purple in Mega Man 5). They appear in almost every Mega Man game. Their only appearance in Mega Man 3 are as "hammer throwers" and in Mega Man 4 as skeletons in Skull Man's stage. They appear to be mass-produced versions of Proto Man, as in their shield design. Proto Man also looks like a Sniper Joe in his Break Man form.

Sniper Joe
Sniper Joes (スナイパー ジョー Sunaipa- Jo-) stand in front of the player protecting themselves with a indestructible shield, sometimes shooting between 1 to 3 bullets or jumping. If the player try to pass by then, they will start jump to the front of the player. They can only be hurt when they are jumping or shooting. They appears in Bomb Man's stage. In the Game Boy game Mega Man: Dr. Wily's Revenge, they always shot three bullets and can't jump. In Mega Man 7 and Mega Man 8, as well as perhaps Mega Man and Bass, the regular Sniper Joes return, except they are better sprites. And in Mega Man 8, they can also throw grenades and lie down as they way to explode.

Robot Walker Joe
