"A Yo-kai that has been trusted to be escorted as part of a entourage of Zazel. His loyalty to try and protect Zazel is so absolute, even if it means throwing away his life. Aristokat was his childhood friend that was found in a luck shrine, he was lucky to have good memories with him."
In his Boss Yo-kai form, he has a much more muscular body, and his robe pulled off of his upper section. He has a thick tuft of fur below his neck, as well as a longer tail, huge claws, and his long, drooling tongue which is constantly hanging out.
In Yo-kai Watch Blasters, Duke Doggy- as Duke Drooly- specializes in melee and claw attacks. If Zazel is defeated before Duke Doggy or Aristokat during the battle, one of them will sacrifice themselves to revive him.
