Malice

Merciless (マーシリス) is one of Xemnas's weapons in Kingdom Hearts 358/2 Days. It is Xemnas's basic weapon, and therefore requires no Gears to be attached to him in order to wield it. In appearance, Merciless is light gray, symbolizing that it is the most basic of all of Xemnas's weapons through the use of achromatic colors.
