Tunnel Rhino

Tunnel Rhino (also called "Screw Masaider") is a Maverick from Mega Man X3. He lives in a rock quarry, and uses his Tornado Fang (that's his drilling weapon) as best he can. Acid Burst is his main weakness, but 1) it takes practice to wield properly and 2) Rhino is invincible while he flashes.
