Togari
Togari is a former Hunter examiner, who returns at the 287th hunter exam. He appears during the third phase of the exam where he confronts Hisoka, not as examiner but to take revenge for Hisoka giving him the two scars on his face from the previous exam. During the battle Togari shows Hisoka how much he has improved his fighting skills being able to use four knives at the same time, Spoiler but despite this it was a quick battle, as Hisoka after being hit few times manages to stop two of his knives and uses them against him. Shocked Togari doesn't have the time to scream that Hisoka effortlessly decapitated him.
