Nonò is a small, sentient robot who serves as the loyal companion of Telemachus, the son of Ulysses, in the 31st-century space-faring adventure. He was given to Telemachus as a birthday present and quickly becomes an indispensable member of the small crew that remains active after Zeus curses the starship Odysseus. Physically, Nonò is a compact, spherical machine, typically depicted in a warm red or orange hue, with a single optical sensor as an eye and a pair of articulated arms. He floats through the air using built-in thrusters, allowing him to move swiftly and navigate tight spaces.

In terms of personality, Nonò is intelligent, logical, and deeply devoted to his human friends, especially Telemachus. He displays a dry, understated sense of humour and a certain innocence that makes him endearing, even when his rational nature clashes with the emotions of those around him. His primary motivation is to assist the crew in any way possible, whether through mechanical repairs, analytical tasks, or providing crucial information. He is not driven by grand ambitions but by a simple desire to be useful and to protect those he cares about.

Nonò’s role in the story is multifaceted. He acts as the technological assistant and resident mechanic, often using his advanced artificial intelligence to translate alien languages, diagnose problems, and operate unfamiliar equipment. He also serves as a source of comic relief, his small size and unexpected reactions lightening tense moments. Despite his diminutive stature, Nonò possesses tremendous physical strength, enabling him to lift or move objects far heavier than himself. He can also perform rapid repairs on machinery and is skilled at improvising solutions when the crew faces unusual obstacles.

His key relationships center on Telemachus, to whom he is closest, as well as Ulysses and Yumi. He interacts frequently with the ship’s main computer, Shirka, but his bond with the human characters is the foundation of his loyalty. Nonò does not undergo any major transformation over the course of the series; his character remains consistently reliable and unchanged, a steady presence amid the crew’s perilous journey. Notable abilities beyond his strength and flight include a positronic brain that grants him advanced reasoning, the capacity to consume and process metallic objects like nails and nuts for sustenance, and a knack for getting into and out of tight spots thanks to his nimble size. His constant companionship and resourcefulness make him a vital part of the Odysseus’s ongoing quest.
