Killua is the deuteragonist and best friend of Gon Freecss in the series Hunter × Hunter. He is the middle son of the Zoldyck Family. Initially, Killua is introduced as a character who seems similar to Gon; cheeky, cheerful, and full of mischievous ideas. He is also one of the most quick-thinking characters in the series. He is confident in his own abilities, often being humble about it. However, his ruthlessness and aptitude in killing shows the other side of him — deadly, violent, and bloodthirsty. Having been tortured since birth, Killua has been conditioned to possess extreme tolerance for poison, electricity and pain. He possesses extraordinary agility and strength that makes Killua a one-man killing machine — definitely not one to be trifled with.
My third favorite character in HxH. He's cool. He's strong. He's deadly. I still remember how shock I was (I'm still a grade scholler at that time) when he suddenly rips out people heart with calm and smiling face.

A man's sword isn't a thing that can be kept in his underwear, its something that should rest in a scabbard known as a girl.
