Leorio Paradinight

Leorio is initially introduced as a very selfish narcissist who places great emphasis on material wealth. Despite his assertions that he is only after money, he eventually reveals to Kurapika that his dream is to one day become a doctor in order to help the poor. He believes that all things in the world (lives, dreams, etc.) can be bought and that becoming a Hunter will provide him with the necessary funds for his medical education. Due to his first spat with Kurapika, as well as the test on the way to the navigator's cabin, it seems that he has a sensitivity for those who do not take him seriously or treat him with disrespect. His real priorities seem to be friends first, then his dream of becoming a great doctor, with everything else afterwards. 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. He often provides comic relief; Killua sometimes ridicules him for his comparatively older age, although he swears that his appearance is that of a mere teenager. His impulsive and brash nature has sometimes caused more trouble for people around him. Another flair he has is his ability to 'straight-talk' through many situations at hand. It could be seen that his closest relationship in the group is with Kurapika because they have spent the most time with each other. At the tail end of the Yorknew arc, Melody claims that he has "the nicest heartbeat in the city", stating that "it's warm and gentle" and that he would make for a better doctor than a Hunter.

Leorio is contacted by Cheadle who asks him to join the Zodiacs and accompany them on their trip to the Dark Continent. She explains to Leorio who is confused that due to his actions during the election, he's highly regarded in the Hunter Association. His presence would surely help the Zodiacs gain the influence needed for their mission to succeed. Leorio, ready to decline, says he has his studies to attend to. Cheadle then informs him that he's been permitted to study abroad with Cheadle as his teacher. Realizing this is a once in a lifetime offer, he accepts being Ging's successor but then asks if there's room for one more Zodiac, nominating Kurapika. As Kurapika is driven to the Hunters Association's headquarters, he talks to Leorio on his phone. Leorio asks him to give him his e-mail address but Kurapika refuses. Kurapika says he has heard of Gon's situation from Mizaistom and inquires if there is anything he can do, but Leorio replies that their friend is fine and that he is more useful in the Zodiacs. Leorio greets Kurapika as the latter arrives to the headquarters, stating that the mission seems more troublesome than predicted and wondering if they will be alright. Kurapika's only concern, however, is why they have been given so little information. Cheadle then leads the way and introduces them to the other Zodiacs. She starts explaining about the V6, the Five Great Calamities, the difficulty of the mission, which is A, whereas the Chimera Ants were ranked B. Leorio grows apprehensive, inferring that the mission he will be embarking in is even more dangerous than the one in which Netero lost his life. Cheadle then asks if anyone has any questions. Kurapika raises his hand, saying he has many. The first is how many infiltrators on Beyond Netero's side the Zodiacs have managed to identify, much to everyone's shock. When Kurapika and Mizaistom come back into the room, Cheadle continues her speech. Leorio claims he will be supporting her medical team in the Dark Continent and he is glad he is given the opportunity to join the expedition, stating he will do his best. He is assigned to the Science Division.
