Illumi and Hisoka

1. Hisoka is portrayed as a cocky, boastful, hedonistic, and self-serving man. He has an insane lust for blood and enjoys fighting strong opponents. While he does like Gon, Killua, and many others, he has stated that, for him, what is valuable one day could easily become trash the next, and he will not hesitate to kill anyone should they not meet his standards.

Hisoka kills people he deems "unworthy," regardless of age or sex. He displays some sadomasochistic tendencies as he derives pleasure from fighting.

2. Illumi, for the most part, displays very little emotion. In contrast to his expressionless demeanor, Illumi often speaks in a somewhat joyful and absent-minded tone. He is generally a stony, ruthless person with an extremely cold way of thinking, reflecting only his own interests. Still, he holds a twisted and overprotective form of love for his younger brother, Killua; this manifests to the point that he used his Nen ability to control Killua and ensure he survives and obeys.

Appearance:

1. Hisoka's appearance resembles a joker or a jester. He is a very tall (6'2") and thin man of about 28 years. He has red hair that points upwards and very pale skin. On his face, he paints his left cheek with a fuchsia star and his right cheek with a green teardrop. He has golden-yellow eyes which often appear eerie and sinister. During his time at the Phantom Troupe, Hisoka wore a fake Spider tattoo created by Texture Surprise, located in his upper back.
2. Illumi appears expressionless, his face like an emotionless mask. He has very long jet-black hair combed behind his head and very large, dark eyes. To disguise himself as Gittarackur, Illumi uses large round head pins to reconstruct his facial structure beyond recognition. The pins in his chest seem to affect the muscles in his body, as he looks more slender without them.
