The twins have gray hair and slightly golden eyes. The female twin, Akira, is an inch taller than Jak. Both are loud and usually let their presence be known. Akira keeps her tail hidden around her waist while Jak lets his curl up from behind him, and usually revels it scaring other children in his class. Jak wears a gray sweater and baggy pants, but Akira wears dresses and slip-on shoes. When training, Akira wears the Saiyan armor her mother made, and Jak wears the armor of a Shadowian created by his father.
