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, except for Mega Man 3 where their brother, Hammer Jack, appears instead. Their only appearance in Mega Man 4 is as skeletons in Skull Man's stage. They appear to be mass-produced versions of Proto Man, as in their shield design.
