Megaman X Command Mission Low level and No hyper-mode run. The Doc Second form. During his def state, the key to beat him lay on the items, this way you can gain turns, and make clean damage to this boss. Be sure to use the def command whit all your party to survive his multiple attack, when he opens his core just attack normaly whit every character, then repeat whit items until you made it. it's recommended to have shield +3 and shield +1 whit every one, cause this boss only use shot type attacks.
