Master Nyada is an older, bronze-colored Cat Yo-kai with drooping eyes and a few little mustache hairs below his nose. His inner ear coloring is light indigo, while his tail flames are purple. His muzzle and paw tips are white, and he has dark, dull brown splotches on his body. He wears a dull green robe and has a wood staff-cane. Nyada is almost a copy of Yoda.
Master Nyada can take on a human form, like many other powerful Yo-kai across the franchise. In his human form, he is called Nick Nack and appears as a rather scruffy middle-aged man with a thin frame, black hair and mustache, an olive green coat and a blue-grey beanie with cat ear-like points.
Master Nyada worships "the hose" instead of the Force. He is very wise and cunning and is also a skilled battle veteran, but due to his old age, he tires easily after a fight.
Master Nyada is said to be one of the most powerful Yo-kai, and while he has proven himself he can only use his power for around a maximum of ten seconds.
As shown in Yo-kai Watch Blasters, he is able to disguise himself as a regular cat. He can also travel through time, as he owns the memory store, although he doesn't say why: he could have been the reason the memory store had the player's Yo-kai Watch.
Master Nyada had Demuncher as a student and trained him.
Master Nyada appears in Chapter 10. Nate/Katie and his/her friends have to look at them in order to train under him to defeat the Wicked. He is found in the Shopper's Row in the past while watching Moximus N's TV show. He has three requests ("Nyada's Test Episode 4", "Nyada's Test Episode 5", and "Nyada's Test Episode 6") which should be cleared in order to progress into the chapter. He gives the "Hose" (which is a normal hose) after clearing his request.
To befriend Master Nyada, the player should clear a quest called "Nyada's Test Episode 3" in order to complete the quest. Once getting the quest, the player can fight Master Nyada every day once.
The Yo-kai that has this will have inspirits from their allies on them for a longer time.

In the anime
Master Nyada appears in the first movie. As the movie is a rendition of the main Yo-kai Watch 2 plot, Nate, Nathaniel and his friends look for him in order to train. Some differences exist from the game's plot: Nyada is found in a yard, and he briefly fights the Wicked. He later appears in a projection during the battle in Dame Dedtime's lair, prompting the heroes to use the Hose, this time to break the rewinding clock.
Master Nyada is an obvious play on the name of the character Master Yoda from Star Wars.
Gran Mangu is a combinación of Gran (Big) and Manguera (Hose)
Master Nyada is an homage to and parody of Grand Jedi Master Yoda from the Star Wars franchise, due to his name and the fact he states to be the master of a power known as "the Hose", a subtle wink to the Force of the aforementioned franchise due to their similar pronunciations in Japanese.
His English voice coincidentally mimics Yoda's voice, which makes the homage even more obvious.
While he is voiced by Naoki Bando in the video games, in the movie he is voiced by famous comedian Ken Shimura.
In Yo-kai Watch 2, his Soultimate has him launching lighting bolts from his paws, similar to that of Emperor Palpatine from Star Wars. From Yo-kai Watch Blasters onwards, the lighting is replaced with blue flames.
Since he is old, his battle style realistically reflects that, but in the games, after a certain amount of turns, he tires out.
Master Nyada's "random" nicknames are: Master N, Foster, Sensei, and Sage.
In the English dub of the Yo-kai Watch: The Movie, Master Nyada sounds like the character Yogurt from the movie Spaceballs, which is a parody of Star Wars. It is unknown whether or not they meant to make Master Nyada share a similar voice to Yogurt, who is also a parody of Yoda.
