"Each of my victims' screams and facial expressions inspired my work."
Benny Delon (ベンニー゠ドロン, Ben'nī Doron) was a famous serial killer who lived about 100 years prior to the present day of Hunter × Hunter that the story takes place in. Due to his excellent forging skills, some would come to regard him as an artist.
Benny seemed to have been on the final stages of male pattern baldness, as a result the hair on the top and the crown regions of his head was missing, while he grew the rest long. He also grew side-whiskers and a beard, and had kept them short and well-trimmed. He was depicted as wearing suits.
Benny was a skilled blacksmith and a serial killer. Every time he killed someone he made a knife engraved with a number and called it Ben's. Probably unknown to himself and likely ignorant of the concept of Nen, he put aura (that has weakened over time or was originally weak) into his knives during their creation that persisted and could be detected by a Nen user via intuition or observed using Gyo. He sold the knives in his shop, like other normal knives and swords. A total of 288 Ben's knives were made. According to his statement while in prison, "Each of my victims' screams and facial expressions inspired my work." This would imply he had murdered at least 288 people prior to being caught. His artistic activity could be divided in at least three periods.
