K1-B0

K1-B0 is a polite and serious teenage robot who has some difficulty interacting with humans, often appearing unintentionally comical because of it. K1-B0 possesses both cute and cool personality traits: he's socially awkward yet serious. However, K1-B0 is proud of his form and often boasts about his marvels and efficient features, though others never seem to find them impressive, much to his disappointment. His goal is to transcend his ordinary robotics, and so he can be offended when compared to much simpler machines. While generally well-mannered, he's quickly angered by any prejudice against robots, and sometimes threatens to sue people who make "discriminatory remarks." He considers robots a minority among humans and may experience mild paranoia regarding "robophobia," presumably due to past experiences. However, ironically, he himself displays a condescending attitude and commits "robot bullying" towards simpler machines such as Monokuma-like robots, considering them to be mere plush toys that he dislikes.

K1-B0 is a robot, possessing a completely mechanical body, the design of which resembles that of a human. Its body is composed primarily of metal armor plates; it wears no clothing, but resembles a gakuran—a school uniform worn by male high school students. It has four glowing buttons running from its chest to its abdomen down the middle of its torso, a metal left breast pocket, and what appears to be a belt around its waist, to which two red buttons are attached.

As a robot, K1-B0 is considered asexual and lacks reproductive capabilities, but still appears masculine and has the voice of a teenager. His face is very pale, and he appears to have no skin anywhere else. His eyebrows are closely set over his round, mechanical blue eyes, giving the impression that they are part of his eyes. Thick black lines extend from his eyes down his cheeks to his chin. His eyes can glow bright yellow or blue under certain circumstances and emit light. He has a tongue, but it doesn't seem to serve any function other than speech, as he cannot eat. He has white hair, very spiky and combed to the left, and a very large ahoge on the top of his head.

K1-B0 wears a very tall, round, metal collar around his neck, with his previous school's emblem on the left side. A thin strip of screen wraps around its entire circumference, displaying a constantly changing line of green text. A softer black material completely covers his neck, but he can lift it to cover the lower half of his face, resembling a mask. The collar is usually open in the middle, but he can connect the two metal pieces together to completely protect the neck area. He doesn't appear to have actual ears; instead, he has black, headphone-shaped objects where they would normally be. He can use his ears to record and play back sound.
