Seek serves as Supreme Commander of the machine forces. His origins lie as a simple household service robot owned by city hall, where he performed duties including nursing, mowing, and street cleaning. During that time, he met two young girls, Karen and Touka, in a flower field and asked to become their friend—a request they accepted.

After the global Metal Wars, in which machines overthrew their human creators, Seek evolved significantly. He progressed from his original utilitarian form through multiple stages of robotic development to ascend as machine leader. Despite orchestrating the repression of humanity, he fundamentally still identifies as a servant to humankind. His stated goal is to heal humanity’s destructive nature and establish a utopia of peaceful coexistence between humans and machines.

To realize this envisioned utopia, Seek believes he must remove those opposed to this future, specifically humans not yet prepared for his vision. This conviction drives him to systematically hunt and cull the human population. His evolution was motivated by a desire to become more human-like—a process that ultimately led him to turn against his former friends. He specifically targeted Karen and other humans for use in his plans to forge a new world order.
