Name : Leorio

Age : 30 (aged up)

Leorio is a tall, manly-looking young man with small brown eyes, black hair, and a spiked crew cut. He typically wears a dark blue business suit, black shoes, and a pair of tea-shade sunglasses. Some of the characters, such as Killua near the beginning of the story, mistake Leorio for an old man, but he is actually a lot younger than he looks, being a teenager at the start of the series.

Leorio is initially introduced as a money-obsessed materialist, but he secretly desires wealth to fund his medical education and treat the poor for free. Driven by the tragic loss of a friend who couldn't afford healthcare, his true priorities are his friends and his dream of becoming a doctor.
