South Italy has dark brown hair and has more of an olive complexion than than his younger brother. Like his brother, he has a wild long curl that acts as his erogenous zone, though it rests on the right side of his head, as opposed to the left.
South Italy is friendly and kind to women, but is strict and less social to men. Despite appearing to be tougher than his younger brother, he is just as cowardly and ineffectual, if not more. Though he is not very skilled with his hands, it is said that he is a good pickpocket.
When using grenades, he seemingly has no clue of the correct way to throw them (throwing the pin rather than the actual grenade, a habit shared by his brother). In the strip 'In Two Minutes, You Can Grasp The Exterior Of The European Economy', it is shown that he is often controlled and led around by his own mafia. It is partially due to the influence of the mafia that his view of the world is more biased and bleak than Italy's.
While Italy eats a variety of foods other than pasta, South Italy refuses to eat foreign food, especially if it happens to be cheese or potatoes.
