So although I wasn’t huge on the beginning of Hunter x Hunter, this was one of the parts I liked — where the viewer really gets to see Hisoka in action.
Hisoka is a dangerous man. That much is clear from the start. But he separates from “normal” dangerous to “crazy” dangerous with how he toys with the main characters. It’s apparent that he could kill them any time he wants. Hisoka beats the shit out of Leorio with ease, and although Gon gets the jump on him, it’s not long before Hisoka has Gon in his clutches. But he doesn’t kill him. Why? Because, as Kurapika later explains, Hisoka senses that Gon can become someone greater, and therefore more worthwhile to kill. It’s more fun to kill someone who will push you to your limit, right?
