While regular Reploids are built to appear human, Mutos Reploids resemble animals and mythological creatures, and are distinguished by their comparatively mechanical cosmetics, and the possession of skills and weapons not available to ordinary Reploids. These aesthetic and practical traits are generally determined by, and allude to, the tasks each Mutos Reploid was created to perform, or a particular elemental force drawn upon during battle, resulting in a potentially unlimited variety of Muto-Reploidic form. Mentally, Mutos Reploids are as humanlike as their anthropic counterparts; each Mutos Reploid has a unique personality and way of thinking, which can be affected by their personal experiences.
