Payn takes the appearance of his pre-evolution with a green head with purple star-shaped marks on his closed eyes, except the head is completely smooth save for a tuft of orange hair on top and a goatee. He also now has a body wearing a brown vest with an omamori hanging from his neck, red pants tied with a belt and carries two dumbbells, and has a long pipe clenched in his teeth.
He retains Ake's abilities to make people's shoulders stiff, complete with the lack of suspicion from his targets. He also has big spirits, and never gives up to the task of causing pain to the shoulders of others even if the odds are against him.
Befriended (Yo-Kai Watch):"Ay, not too bad, eh! Let's be pals?"
Loafing:"I'm tired..."
Receiving food (favorite):"There we go!"
Receiving food (normal):"Well then..."
Receiving food (disliked):"*hock* Ptew!"
Freed from Crank-a-kai:"You must be strong to get me outta there. We're gonna be buddies!"
In the anime
Payn, along with Ake appear in Yo-kai Ake and Payn, when they try to make Nate's shoulders stiff. Despite their task being difficult, Payn gives Ake a motivational speech where he inspires him to continue the attempt. Despite this, they do not succeed. The pair then gives Nate their Yo-kai Medals.
Etymology
"Payn" is a corruption of pain.
"Katanori-oyakata" translates as "shoulder-riding mentor", while playing on katakori (肩凝り, "stiff shoulders").
"Agujeto" is a corruption of agujeta (shoe lace or pain).
"Peyn" is a corruption of "Pein" (torment, suffering).
Origin
Payn shares its inspiration with Ake, with the addition of the facial hair, clothing and omamori worn around the neck (an old-fashioned custom, somewhat comparable to wearing a crucifix in several Christian countries) creating the impression of an exercising old man.
Like Ake, he is based in the Yōkai Obariyon.
Trivia
In the English dub of the Yo-kai Watch anime series, he has a twig from his mouth rather than a pipe due to regulations involving smoking being too inappropriate for western children's television standards.
