Pork Pie Hat Kid is a skinny and short young boy, hiding his bald head with bamboo sticks. He has a large, angular jawline and shows his teeth constantly. He also possesses large black irises.

Pork Pie Hat Kid wears a sleeveless suit, open and laced at the back and decorated with studs arranged vertically on both sides of the chest and both legs, as well as short feathers on the shoulder and finally a tutu-like short dress. He also wears large bracelets adorned with leaves on both wrists.

Due to his Stand Wired, Pork Pie Hat Kid's tongue has two hook-shaped cavities and the bottom of his mouth has two wheels around which the cables of Wired can roll.

Pork Pie Hat Kid appears to be a goofy and deranged individual. He seems to have little conception of normalcy and shows several disturbing habits. For instance, he has a tendency to eat and drink anything that comes into his view such as the ink of a pen (finding it delicious) or a whole coffee pot, and even wonders if he could eat his broken teeth. He is also shown hitting a bag with a rock to search it instead of opening it. Like any of Valentine's subordinates, he has little problem with using violence and killing his targets.

Despite his quirks, Pork Pie Hat Kid is still shown to be a capable tactician in a Stand fight. Aware of his primary objective of securing the Corpse Parts, he takes the time to analyze the situation and is shown to devise several plans to counter his enemy's actions, at one point using Gyro as bait after having predicted that Johnny would come to save his companion or release Slow Dancer near Johnny to weaponize the horse' instinctual will to go to its rider and then detect the hidden Johnny.
