Killua

The deuteragonist of the anime/manga series Hunter Hunter is Killua Zoldyck. He is Gon Freecss' best buddy and the middle kid of the Zoldyck family. Killua, who comes from a line of assassins, underwent various severe training regimens starting at a young age. Killua completed the training programs thanks to his extraordinary talent. Killua is a caring individual, unlike the majority of his family, and he has a special bond with Alluka, his younger sister.

As the middle child of the notorious assassin family Zoldyck, Killua was born. Killua has already demonstrated significant promise at a young age and is poised to become one of the most skilled assassins the family has ever produced. Alluka is emotionless since she is shunned by the rest of the family, but when she meets Killua, she is ecstatic. Killua resolves to put his life in danger to save Alluka following the Chimera Ant arc, demonstrating how important she is to him.

At first, Killua is presented as a person who resembles Gon in that she is cheeky, upbeat, and brimming with wicked ideas. He is also one of the series' characters with the best quick thinking. He frequently displays humility while being confident in his own abilities. No wonder why he is considered as one of the greatest brother characters in anime.
