X=robot. Robot=metal. Metal=strong. Mega man x is made from an extremely powerful alloy. He can fall and still not be damaged. If cloud wants to waste his time chopping down trees liek a lumbarjack thast fine. Even if he gets one when x is there, when x is falling, he could just aim upwards, and fire shots right through clouds skull. When cloud charges him, all x has to do, with his immensially powerful legs, is jump up high in the air to avoid him.
