Hisoka Morow

Hisoka Morow is a main character in Hunter x Hunter (2011) and a dangerous fighter whose cruelty, deception, and unpredictability make him difficult to read in battle. He uses Shu-powered playing cards as precise weapons and is constantly interested in finding strong opponents. His fascination with Gon's potential is strong enough that he is willing to help him—or simply avoid defeating him too soon—so that Gon might eventually become a more challenging adversary.
