(Warning this will have spoilers to egghead) York, also designated as Punk-06 (PUNK-06パンク シックス, Panku-Shikkusu?), is one of the six satellites of Dr. Vegapunk, embodying his aspect of "greed". She acted as an ally to the Straw Hat Pirates at first, but was later revealed to be a traitor responsible for instigating the Egghead Incident and many of the events prior during the Egghead Arc. And she's a menace to society.
