Ging Freecss is the father of the primary protagonist Gon Freecss. His departure becomes Gon's motivation for becoming a Hunter. He is a Double Star Archaeological Hunter (though he can apply for a Triple Star License), and a former Zodiac with the codename Boar.
Ging appears to be wearing a turban-like-cap on his head most of the time with some hair locks popping out from it, he also wears plain baggy white pants and a long sleeve shirt. On top of that he has a slip-on-head cloth that looks like a tank top and stretches down to the waist and hangs off the waist all the way down to the knees without covering the sides of his legs, and he fastens that cloth with a black belt-like band on his waist. He also wears a normal dark blue/grey scarf wrapped around his neck and long skinny black crew boots.
Ging is seen as a short guy who appears to be a bit taller than his son Gon. He has hazel/brown eyes, short facial hair and long spiky/wavy hair.
Ging has a shy and stubborn personality, to the point that he only wants Gon to meet him alone and claims that it would be cowardly of Gon to bring a friend to meet him, causing one of his friends to wonder if he is afraid of crowds. Judging by his actions at the New Hunter Chairman Election to ensure Netero's will be carried out, he seems to respect the late Chairman considerably.
Ging is the only grandson of Gon's great-grandmother. He and Mito are cousins. Ging left Whale Island to take the 267th Hunter Examination not long before turning 12. Right after his departure, Mito's parents and his father died consecutively. He was the only participant to pass the 267th Hunter Exam.
Ging returned to Whale Island ten years afterward with a two-year-old Gon. He intended to leave Gon in the custody of his grandmother for a while, telling her that he and Gon's mother had separated. However, he lost the custody of his son in court to his cousin Mito.
After becoming a licensed Hunter, Ging devoted himself to the excavation and preservation of archaeological ruins. He used his own fortune to accomplish a perfect preservation and restoration of the ruins so that everyone can see them. His achievements in archaeology are now considered an exemplary model for working on ruins throughout the world.
Ging has become very rich and as powerful as a president of a country. He is currently a Double-Star Hunter and qualifies for a Triple-Star License, but because of his shyness and stubbornness, he has not applied for one. He has, however, remained a mysterious figure and information about him is classified even in the official Hunters database. One of the few things known about him is that he is the main creator of the Nen-based game Greed Island. Chairman Netero once told Biscuit that Ging was one of the five best Nen users in the world.
After Netero's death, it is revealed that Ging is one of the twelve Hunters hand-picked by the former Chairman to be in charge of the election for a new Hunter chairman: the Zodiacs. They all were given code names based on the signs of the Chinese zodiac, with Ging being known as "the Boar".
