Nobel is a supporting character in the anime Technoroid: Overmind. He is an android whose full background remains vague, with his serial number unknown, though there is a possibility that the prefix NO refers to the element nobelium from the periodic table. He is a member of the unit Karakuri Shinshi.

Nobel is portrayed as a mysterious figure who appears when the main group KNoCC is in a difficult situation, offering assistance without any sign of malicious intent. His personality is calm and composed, and he emphasizes the importance of balance, as reflected in his quote about searching in balance. His kokoro—the android equivalent of a heart or emotional core—is notably well-developed, granting him a deep understanding of music and likely contributing to his composed demeanor.

In the story, Nobel functions mainly as an ally who aids KNoCC during critical moments, but his own motivations are not explicitly explored. He does not undergo significant visible character development within the anime, remaining an enigmatic presence. His notable abilities include his musical proficiency, which aligns with the series’ focus on performance, as well as the general capabilities common to androids in the setting. His relationships are primarily defined by his supportive interactions with KNoCC, particularly in times of crisis.
