Zulius is quite sassy, flamboyant, and sometimes self-obsessed. He can often be seen judging his appearance by using a mirror. Any time there is even a slight flaw in his appearance, he becomes distraught and disgusted. He also greatly dislikes being called old. This implies that he is obsessed with perfection as well as very self-conscious. When Zulius isn't focused on his own appearance, he tends to judge other characters.
