Snake Man

Snake Man (スネークマン Sunēkuman) is a Robot Master with a snake motif created by Dr. Wily and Dr. Light to investigate narrow areas and survey topography on uninhabited planets marked for development. With his quick and lightweight body, Snake Man was well-suited for work on any kind of terrain. However, this caught the attention of Dr. Wily, who stole him, reprogrammed him into a combat robot, and sent him to work in order to fulfill his schemes. Snake Man is also the first Robot Master to have an animal-themed design.

His Special Weapon is the Search Snake, serpentine missiles that can move swiftly along the ground and even climb up walls. In Super Adventure Rockman he is shown to be able to dig underground to stay out of sight and ambush opponents, or to avoid their attacks.

Trivia

 * Snake Man is shown having his cannon placed on his right hand in certain shots, such as in the Mega Man 3 game itself. In the Ruby-Spears cartoon, Snake Man's cannon was put on his left arm to match his artwork.
 * Snake Man is also able to morph his cannon into a hand in the Archie Comics, and has it on his right arm.
 * Snake Man is credited to liking Toad Man and disliking slugs; this most likely comes from a Japanese variation of Rock Paper Scissors; where Snake beats Toad (the snake can swallow the toad), Toad beats Slug (the toad can swallow the slug), and Slug beats Snake (the slug, by covering its prey with a slimy secretion, can destroy a snake). This would also explain why Toad Man is credited as disliking Snake Man also. Also, some snakes eat toads in real life.  Archie Comics makes a note to this in Sonic Universe #250, where Snake Man is seen waving at Toad Man while the latter stares at him suspiciously.
