Some fighters want victory.
Some want glory.
Hisoka wants the fight to be interesting.
Hisoka Morow is one of Hunter x Hunter's most dangerous recurring wild cards: a magician-styled Hunter, extraordinarily skilled Nen user, and combat obsessive whose allegiance at any particular moment can usually be summarized as whatever makes things more entertaining for Hisoka.
That makes him extremely difficult to categorize.
Villain? Frequently.
Ally? Occasionally.
Trustworthy?
Absolutely not.
Hisoka is fascinated by powerful opponents and, even more dangerously, people he believes may someday become powerful enough to challenge him. Rather than simply eliminating every potential threat, he'll sometimes preserve one, encourage one, or manipulate events around one because today's unfinished fighter might become tomorrow's magnificent battle.
Gon earns exactly that kind of attention.
Behind Hisoka's theatrical presentation is a remarkably tactical fighter. He's a Transmuter, and his signature Nen ability, Bungee Gum, gives his aura elastic and adhesive qualities. The basic concept sounds almost silly.
Hisoka makes it terrifying.
He uses Bungee Gum for traps, movement, deception, defense, manipulating objects, redirecting attacks, and improvising solutions his opponents frequently don't recognize until they're already caught in them. Combined with Texture Surprise, deadly playing cards, physical skill, and an exceptional talent for misdirection, Hisoka fights like a stage magician whose final trick is explaining that you've been losing for the last five minutes.
Even his relationship with the Phantom Troupe operates according to Hisoka logic. He infiltrates the group because membership puts him closer to its immensely powerful leader, Chrollo Lucilfer, whom Hisoka desperately wants to fight. The spider tattoo marking his supposed membership is itself a deception.
Because apparently even joining a murderous criminal organization isn't sufficiently dramatic unless Hisoka can make it part of the trick.
That's what makes him such an enduring Hunter x Hunter Character.
Hisoka doesn't need to control the story.
He just needs to keep wandering into it, smiling, shuffling the deck...
And wondering whether anyone nearby has finally become interesting enough.
