Knuckle Joe's father looks just like his own son. He is just older than his son and his legs are much shorter than that of his son, meaning he just has feet connected to his body. His skin is a purplish color, and he has the same yellow hair and elf ears as his son, as well as purple eyes. He wears a gray mask over his face as well as a grayish blue, short-sleeved jumpsuit with a white stripe and a black squarish shape on its front with white linings and a star on it. He wears dark grayish blue shoes and grayish gloves, and he wears a light grayish green cape. He carries a green shield with a yellow magic symbol and a blue gem on its front, as well as a sword, and wears a locket round his neck that has a similar symbol to the one found on his shield. His locket contains a microchip inside, as well as Knuckle Joe's baby picture. His face under the mask is never seen.
