Background
Still a great mystery, no one knows where he came from or who he really is. Even Hisoka may not even know himself, preferring to forget his past.

Attributes
An erratic, volatile, killing machine that enjoys the act of killing, especially people whom he has targetted as victims, one being Gon. Thinks he's the best fighter in the world, and always seeks to challenge anybody who appears to be equally powerful as him. He has set his current sight on Kuroro, the leader of the Brigade, finding him to be a worthy opponent which he would want to <kill> with relish.

Fighting Ability
Arguably one of the best fighters in the world, Hyskoa is not only deadly in normal attacks, but has many tricks up his sleeve--his deviousness and volatility has made many opponents difficult to anticipate his next move, and this has led to him winning many battles. Using poker cards as his weapens, he throws them with ease and deadly accuracy, which cut into enemy flesh like a knife to butter.
