K1-B0 is a polite and serious teenage robot, who has some trouble with human social interaction and often comes across as unintentionally comical as a result. K1-B0 has both cute and cool characteristics, with him being socially awkward but serious. His aim is to overcome being an ordinary robot and because of this, he may get offended if he is compared to much more simple machines. While generally well-mannered, he is quickly angered by any prejudice against robots and sometimes threatens to sue people who make "discriminatory remarks".
