Daiz in Yo-kai Watch 2

Daiz can be found as an overworld enemy in the Jumbo Slider area outside the bathroom (in the forest above Breezy Hills). Use a nearby tree to reset the overworld Yo-kai until he appears, then catch him.

He can also be freed from the Crank-a-kai with a Bird, Moon or Wind Excitement Coin.

He can also be found at the Happy-Go-Lucky Express at and can be battled 4 to 6 times. The Daiz there also give a very large amount of EXP, making it good for grinding.
