Red Lotus Saber: (紅蓮剣) Zero's fastest weapon in Megaman X Command Mission, this blade drains all of Zero's power and channels it into a giant flame blade, and unleashes it in a fire elemental triple slash called the Bone Slicer. However, since the blade drains so much power, it almost completely annihilates Zero's defense stats, making him extremely vulnerable. It drops after defeating Fourtails.
