Wood Man

Wood Man (ウッドマン Uddoman) is a combat Robot Master created by Doctor Albert W. Wily using natural Japanese cypresses. He has a very unique design due to his body being made almost completely out of wood- including his internal mechanisms, along with a thin coating of metal for extra protection. Because of this, Wood Man has great strength and resistance against physical blows, but is somewhat slow and highly vulnerable to fire and cutting weaponry.

His Special Weapon is the Leaf Shield, leaf-shaped pieces of Ceratanium that are sharpened around the edges and levitated using electromagnetism, and can be used to protect himself and attack enemies in different ways, including launching them in rings of four or eight, and summoning them down from the ceiling to fall down onto the target. Due to his flammable construction, his primary weakness is the Atomic Fire.

Wood Man is apparently one of Dr. Wily's favorite robots, due to his unique, resilient design, and according to the amount of times he has been called into action against Mega Man.

Trivia

 * Wood Man is the first robot in the series known to have a body made of natural resources. A problem with this is that, unless laminated or otherwise treated, Wood Man's wooden parts could eventually rot over time, which would mean replacement parts would be needed every once in a while. However, Wood Man has a thin metal coating that apparently serves as lamination.
 * There is a semi-popular internet meme of a crudely-drawn Wood Man, often associated with the caption "nice >:]".
