K1-B0 has both cute and cool characteristics, with him being socially awkward but serious. Nevertheless, K1-B0 takes pride in his form and often boasts about his wonderfulness and efficient functions, even though the other students never seem to find them impressive, much to his disappointment. 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. Hates when someone acts robophobic.
