Movie
Description
Master Nyada is an elderly, bronze-furred cat yo-kai. He has drooping eyes, a sparse mustache, light indigo inner ears, and purple tail flames. His design features a white muzzle, white paw tips, and dark brown body splotches. He wears a dull green robe and carries a wooden staff-cane. This yo-kai can transform into a human form, appearing as a scruffy middle-aged man named Nick Nack who wears an olive green coat and a blue-grey beanie with cat-ear points. He can also disguise himself as a regular cat.

A battle-hardened veteran, Master Nyada channels mystical energy called "The Hose". His advanced age limits his stamina; he tires rapidly during combat, typically maintaining peak effectiveness for only about ten seconds. His abilities include dodging and countering attacks using "The Hose", temporarily boosting ally statistics with the "Hose Be With You" inspiration, and unleashing area-of-effect damage via his Soultimate Move "The Hose". This Soultimate Move first manifested as lightning bolts before evolving into blue flames later. He also owns a memory store, suggesting time travel capabilities.

Narratively, Master Nyada serves as a mentor. In Yo-kai Watch 2 and its movie adaptation *Yo-kai Watch: The Movie*, he trains protagonists to combat the Wicked Yo-kai through trials required for progression. During the movie's climax, he appears via projection to instruct heroes on using "The Hose" to dismantle a rewinding clock mechanism. He also trains the yo-kai Demuncher as a student. His involvement spans multiple games: Post-game activities in Yo-kai Watch 2 feature daily "Nyada's Trials" parts IV-VI for befriending after initial story tasks. Yo-kai Watch 3 incorporates him via the "Two Photos Short of Fifty!" quest, triggering an auto-befriending battle upon photo collection. In Yo-kai Watch 4, he grants a keystone for completing Detective Agency Request No. 13 and appears rarely near the Sakura-Motomachi Ark Door. Spin-offs like Yo-kai Watch Blasters and Busters 2 include him as a potential mission recruit or supporter circle requirement.

Personality-wise, Master Nyada exhibits wisdom and cunning reflecting his extensive combat experience. His dialogue frequently includes wheezing or breathless interjections consistent with his elderly state. He reveres "The Hose", often advising others to "Use the Hose" during pivotal moments.
