K1-B0

K1-B0 is a humanoid robot with a build similar to a teenage boy, encased in sleek white and charcoal-gray metallic armor plating. He has spiky silver-white hair featuring a prominent mechanical antenna and bright cyan blue eyes with faint circuit patterns. His body is detailed with glowing blue lights on his chest and joints, giving him a high-tech yet approachable aesthetic.

Polite, earnest, socially naive, sensitive, defensive against robophobia, and justice-oriented.

Ultimate Robot / Student

Created by the scientist Professor Idabashi, K1-B0 was built with a sophisticated artificial intelligence that allows him to learn and mature like a human child. He was raised by the professor as his own son before being enrolled in the Ultimate Academy for Gifted Juveniles to participate in a killing game. Unbeknownst to him for much of the journey, his inner voice actually represents the collective will and votes of a global audience watching the events as a reality show.
