The Zoldyck family are a group of Assassins that are famous in the world of Hunter X Hunter. They are the world's most famous killers. They eventually had a son that they maned Killua. Kiillua was a prodigy at birth and showed great potential. Eventually Killua got angry and cut up his brother and mother and left the Zoldyck family mansion.
Killua eventually reaches the first stage of the hunter exam. Before the stage begins Killua meets with the rookie crusher. The rookie crusher tries to poison him but Killua reveals that poisons don't work on him. He eventually interacts with Gon and they quickly become friends. They both race each other to the halfway point of the first exam. It ends in a tie. Killua sticks around with Gon and his group for awhile. Gon and Killua are eventually challenged by Netero to a game of take the ball. The goal is to steal the ball form the old man. Killua and Gon attempt to grab it many times but ultimately fail. Killua gives up and leaves. He monologues to himself when a couple of people come up to him and push him around. He kills them in response saying that he would have killed the old man to get the ball. At the end of the Hunter Exam Killua faces off against who is latter to be reveled as his brother. Killua is put into complete fear. He quits the match and kills another participant before eventually leaving the building and returning home.
Gon learns about what happened to Killua and decides to try to rescue him from his mansion. Killua spends most of this arc talking with his family. He makes a deal with his father to never betray his friends. His father let's him go free with his friends. His mother is against this believing that this is a crucial time to hone his skills. Killua eventually sits in a room waiting for Gon to get there. Because he grows impatient, Killua goes out to see if Gon is there in the room. Gon is in the room and he eventually finds Gon and leaves the building and mansion with him.
