Kougenjin

Kougenjin (光幻刃) is the EX Skill that ZeroXorZ obtains by defeating Sage Harpuia with an A or S rank in Mega Man Zero 2. With it, Zero releases a short-ranged shockwave from the Z Saber. In Mega Man ZX, with Model OX in O.I.S (Overdrive Invoke System) mode, by holding down and pressing the main weapon button, he will do a thunder-element attack similar to Kougenjin.
