Uncle Infinite is a recolor of Papa Bolt. He appears as a humanoid Yo-kai with brown skin, grey hair and a grey beard. He wears a purple sleeveless kimono with gold accents, including a large golden rope coiled in three circles on his back. He rides a dark storm cloud.
Uncle infinite rarely appears at the summit of Mount Wildwood on cloudy and rainy days and nights in the mounted binoculars.
A useful trick for befriending him is, if the player calls Drizzelda to her Yo-kai spot, the player can ask her to change the weather from rainy, and continue to do that. Each time she changes the weather from rainy to rainy, the Yo-kai in the binoculars will change. When your Yo-kai meter reads S-Rank, the player can go to the binoculars and battle Uncle Infinite.
