Gokumonken (Mega Man)

Gokumonken (獄門剣 lit. "Prison Gate Sword"), is the special technique that Zero learns after defeating Soldier Stonekong in Mega Man X7. By holding down the attack button while standing still, Zero enters a defensive stance. While he's glowing, enemy projectiles are blocked and he will automatically counterattack any enemy that approaches with a powerful strike.

This technique is Tornado Tonion and Sigma's (second form, deflect his energy orbs) weakness, being able to inflict considerably more damage to him than the Gaea Shield and interrupt his attacks. It is also able to destroy highly resistant enemies such as Large Mines, foes that otherwise can only be destroyed by Ride Armors.
