The Zoldyck family is a group of powerful assassins in Hunter x Hunter. Known to be the strongest assassins in the entire world, these people take up contracts to eliminate high-level threats that need to be dealt with. The Zoldyck family is situated at the top of Kukuroo Mountain and fans got to explore this family during the Killua mini-arc in the anime.
Known to have been prominent for decades, this family has seen the rise of several powerful fighters over the years. While some of them are just your average assassins, other members of the Zoldyck family have frightening strength up their sleeve.
10 Milluki Zoldyck
Milluki is by far the weakest member of the Zoldyck family. Despite being the son of Silva and Kikyo, he has little to no training in advanced assassination skills. His strengths lie with technology. Even compared to kids such as Kalluto, he doesn't seem to be all that impressive. So far, very little of his nen abilities have been seen, but he is known to be a Manipulation type nen user.
9 Kikyo Zoldyck
The wife of Silva Zoldyck, Kikyo is also a powerful assassin of the Zoldyck family as well. While very little of her abilities have been seen in the story so far, she is known to be a Manipulator nen user.
Kikyo does have some advanced skills up her sleeve, as was seen when she used her fan to knock Canary down from a distance, however, compared to the rest, she isn't all that powerful.
8 Kalluto Zoldyck
Kalluto is the youngest member of the Zoldyck family. His skills with nen are advanced enough to be considered as one of the members of the Phantom Troupe. After Hisoka left, he was given the number 4 position in the Troupe.
Kalluto is known to be a Manipulator and can infuse Origami art with nen and use it in combat. In the Chimera Ant arc, fans saw him take on one of the lower-ranked Ants and he fared well against them.
7 Killua Zoldyck
One of the main characters in Hunter x Hunter, Killua is quite possibly the most prodigious member of the Zoldyck Family. He is known to be a Transmutation type of nen user and his skill with this ability is immense. Over the several arcs of the series, Killua has continuously grown stronger.
During the Chimera Ant arc, he was able to fight even Menthuthuyoupi momentarily, which is nothing short of impressive. His potential is limitless and he will continue to go stronger in the future.
6 Illumi Zoldyck
The eldest child of Silva and Kikyo, Illumi is quite a talented assassin whose skill is often compared to the likes of Hisoka. He is a Manipulator type of nen user, like most of the family members, and his skill in this art is immense, as seen through the various arcs of the story.
Illumi is stronger than Killua at the moment and will likely still have room to grow further. He most certainly ranks among the strongest members of the family.
5 Zigg Zoldyck
Very little is known about Zigg Zoldyck as he is one of the oldest members of the family. However, what fans do know is that he once traveled to the Dark Continent with Netero.
That alone is a feat good enough to for him be considered among the strongest members of the group. Zigg also returned from the Dark Continent safely, meaning his survival skills and grasp over nen are both refined to a great degree.
4 Silva Zoldyck
Silva is the current leader of the Zoldyck Family and quite possibly the strongest member in their ranks right now. He is a Transmutation type of nen user, like his son Killua. Silva is able to transmute his aura into electricity.
Speed and ferocity are two of his biggest strengths in combat. He's previously clashed against the likes of the Phantom Troupe and kept up with even Chrollo in combat. Without a doubt, he ranks among the strongest characters in the series.
3 Zeno Zoldyck
Killua's grandfather, Zeno is an exceptionally powerful nen user. Although he's old and now probably beyond his prime, he's still strong enough to take on the top tiers of the Hunter x Hunter world.
Zeno is a transmutation type of nen though, although he can also use some other types such as Emission and Manipulation. His skill was such that Chrollo was forced to take him seriously in combat. What's more, even Isaac Netero recognizes his skill, which is a testament to his strength.
2 Maha Zoldyck
Maha is one of the legends of the world of Hunter x Hunter. He is quite possibly the strongest known human in terms of strength and prowess that fans know of. It is believed that anyone who faced him in combat didn't live to see the next day.
Isaac Netero, chairman of the Hunter Association and also the strongest nen user, was the only one who survived a fight against Maha, which goes to show how skilled he truly is. Little to nothing has been seen about his nen abilities, however, he's known to have been an Enhancer.
1 Alluka Zoldyck
Alluka is the second-youngest child of the Zoldyck Family. While she is physically the weakest of them all and doesn't even possess the ability to use nen, she is also the most frightening.
Alluka was once possessed by an unknown entity from the Dark Continent, which the family named Nanika. Thanks to its power, Alluka has become a frightening force. Her strength is such that the entire family fears being wiped out in an instant due to Nanika's influence.
