The Zoldyck Family, also known as the Zaoldyeck Family, is a famous fictional family of assassins appearing in the Japanese manga and anime series Hunter × Hunter.
The Zoldyck family is considered by and far the most deadly of assassins in the Hunter × Hunter world. The family owns and lives at Kukuroo mountain, a dormant volcano in the Dentora region of the Republic of Padokea. Their estate is surrounded by huge stone walls guarded by a giant dog named Mike and highly skilled attendants. Few people unrelated to the family have any idea what is within the estate. There is lots of mystery surrounding the Zoldyck family; a single photo of any of the members can be sold for millions.
Children in the family are trained from birth in the art of assassination, although each member of the family has the privilege to choose the specialty of their forte and liking as they grow up. For example, the oldest child Illumi seems to be a master of disguise; where as the next oldest, Milluki, is a computer wizard and expert hacker. In every generation, there appears to be a prodigy child whom would be named as their heir. Currently, the heir to the Zoldyck business is Killua, one of the four main characters of Hunter × Hunter, though Killua has stated that he has no desire to inherit his family's occupation.
It is believed that each member of Zoldyck's family begun their training from their date of birth. They possess a unique set of talents: resistance to almost all types of poison, the ability to tolerate high amounts of electricity, and immense strength (Killua was able to open a 16-ton door before receiving any form of nen training).
