Tunnel Rhino

Tunnel Rhino, known as Screw Masaider (スクリュー・マサイダー) in Japan, is a Maverick from Mega Man X3. He lives in a rock quarry, and uses his Tornado Fang (his drilling weapon) as best as he can. Acid Burst is his main weakness, but it takes practice to wield properly and Rhino is invincible while he flashes.

Zero, in Mega Man Xtreme 2, can take him with Earth Gaizer.
