Goldenyan is one of the Yo-Kai required to unlock Gilgaros.
A gold-plated robotic cat Yo-kai. Goldenyan has big sky blue eyes, an orange nose, and dull blue inner-ear. She has a wide opened mouth and pale yellow muzzle and chest. A big blue sphere rests in the center of the chest. Where her arms begin is a single piece of brown material, matching the pale brown band around the stomach. A jet pack is visible on the back, while the tail flames are blue. Her appearance is almost identical to Robonyan's.
In Whisper's dream the anime, Goldenyan is a bit vain; she states she can only shine in certain places since she is gold-plated. She also leaves when Katie summons her with her Yo-kai Watch.
Similar to Robonyan, she says "I'll be back" when she leaves. In the English dub, it says "Golde-nyout" when it leaves.
Goldenyan can be freed from the Crank-a-kai by using either Orange Coins, Five Star Coins or Special Coins.
In the first game, a Goldenyan lies in a state of low power within the Trophy Room located in the center of Gourd Pond Park, which is firstly accessed to the player by obtaining their first Yo-criminal Trophy. By collecting Trophies of captured Wanted Yo-kai, it helps revitalizes Goldenyan until she can stand. Collecting more Trophies help further optimize Goldenyan. Doing so will reward the player with 10 Crank-a-kai Coins of the following colors:
Enough so Goldenyan is standing: Red Coins
Half of Yo-criminal Trophies collected: Yellow Coins
In a dream in EP067, Katie summons Goldenyan -which refers to as "her best Yo-kai friend" with her own Yo-kai Watch in order to deal with Noway. However Goldenyan herself states she only shines in certain places and, despite Katie's pleads, leaves through a portal.
In Spanish, "Aureonyan" is a combination of áureo ("golden") and nyan.
In Portuguese, "Orobonyan" is a combination of Oro ("gold") and robonyan.
Despite only appearing in a dream, Goldenyan has her Yo-kai Medal registered in the Recap Time of said episode, along with Shadow Venoct.
Goldenyan's model was changed from the original Yo-kai Watch when the sequels were released. Goldenyan's model henceforth has been changed to have more of a gleam to it, rather than the solid gold/yellow color seen in the original Yo-kai Watch.
Her random nicknames are Solid, Goldberg, G-800, and Gilgameh.
Goldenyan was the only Crank-a-kai exclusive yo-kai to neither appear in the overworld or an infinite dungeon until Yo-kai Watch 3.
Goldenyan's gender was changed from female to male in the dub. Why this was done is unknown.
