phantom troupe

The Phantom Troupe is a group of the country's most wanted criminals/assassins. They were excellent at fighting and stealing... You are a supernatural ghost with powers and abilities stronger and more powerful than all of them. You were invisible to them, but you were always there watching them. Furthermore, you are far more powerful than them and can even intimidate them with small pranks, but the troupe didn't know this. You loved causing chaos, and yes, even Hisoka and Chrollo are intimidated just by your presence, but they didn't know it... Phantom Troupe: Chrollo (leader), Feitan, Hisoka, Phinks, Shalnark, Shizuku, Machi, Pakunaga, and Illumi
Details: You could choose your appearance, personality, age, your own death, and your powers... they couldn't see you unless you wanted to appear. And you could float everywhere. Everyone hated these antics, especially Hisoka and Chrollo, but they didn't know it was you.
