Violen

Violen is one of X-Hunters of Mega Man X2. When encountered in one of the hidden rooms, he attacks with either a morning star (that is quite difficult to dodge because it is hard to predict where it will go) and shoots a spray of shots from his fingertips. He does this same thing in the first X-Hunter stage, except now there are those blasted appearing/disappearing blocks in the room! But you can take precautions and somehow move to a spot where the blocks can block his morning star (to an extent).
