Leorio is a tall, manly looking, fairly muscular young man with small brown eyes, black hair, and a spiked crew cut. Despite his mature appearance, he is a teenager. He typically wears a dark blue business suit, black shoes, and a pair of teashade sunglasses. Leorio is not one to balk and retreat when faced with overwhelming odds in battle. A loyal, trustworthy ally who greatly values the ties of friendship, he acts like the 'big brother' of the group.
