Koltopi Tounofmaill
コルトピ
The most distinctive thing about Koltopi is his haggard appearance. A thick and messy mane of hair flops down his face, obscuring everything except for an occasional glimpse of his eyeball.
In the Dark Continent Expedition arc, Chrollo is using his Gallery Fake ability during his fight with Hisoka, implying that Koltopi lent him this ability.
In chapter 357, he is apparently using a nearby bathroom while Shalnark discusses their plans to travel to the New Continent over the phone with Chrollo. Once Shalnark notes that Koltopi has been taking a long time doing so, it is revealed that Hisoka killed him when he emerges with Koltopi’s severed head in hand.
