Wild Boy is a cat-like Yo-kai Hero. He has Goromi's yellow color scheme, but is more humanoid. Unlike Kengo Benimaru, his true face is shown a pair of gleaming vivid cyan eyes peeking out from black glasses along with vivid cyan inner ear colors, a white nose and his white 'muzzle' mouth while he has one yellow tail with two spikes on both sides near the pointy tip.
He wears a black cowboy hat-like fedora with two bright green stripes on the left side with silver rectangular-framed goggles with amber-colored lens along with a silver necklace with a matching colored lightning bolt, a black vest with a bright green stripe on both sides united in the shape of a 'V' and has two bright green spines protruding upward from both sides of the 'V' on the back of his vest with a small one under the bigger one.
Wild Boy has black, baggy pants with a bright green belt with a diamond-shaped buckle and a dangling strap on both side with the same buckles whilst, he wears black wrist sweatbands with a bright green ring-like stripe on the bottom of them and wears black-colored, square-toed, western ankle harness boots with bright green heels and soles and matching colored boot straps along with a bright green stripe on the middle of both boot tongues. His weapons, called Wild Shooters (Japanese: ワイルドシューター Wairudoshūtā), are two bright green and dark gray modern revolvers with gray and dark gray cylinders and unique barrels.
