The Hunter × Hunter manga series features an extensive cast of characters created by Yoshihiro Togashi. It takes place in a fictional universe where licensed specialists known as Hunters travel the world taking on special jobs ranging from treasure hunting to assassinations. The story initially focuses on 11-year-old Gon Freecss and his quest to become a Hunter in order to find his father, Ging, who is himself a famous Hunter. On the way, Gon meets and becomes close friends with Killua Zoldyck, Kurapika and Leorio Paradinight, who all aim to become Hunters for their own reasons, and catches the attention of the murderous magician Hisoka.
After becoming licensed, they clash with a gang of thieves known as the Phantom Troupe, before Gon and Killua enter the video game Greed Island in search of clues to find Ging. The two then immediately get involved in stopping the man-eating Chimera Ants from taking over mankind. Kurapika, Leorio and the other Zodiacs, a group of high-ranking Hunters, then begin escorting the Kakin Royal Family and Beyond Netero on an expedition to the unexplored Dark Continent. However, the ship ride is the start of a deadly game of succession among the princes to determine who will be the next king of Kakin.
Although the characters are humans, most possess superhuman strength and/or supernatural abilities due to Nen, the ability to control one’s own life energy or aura. The world of the series also includes fantastical beasts such as the Chimera Ants.
