Damon's face and neck are partially covered by strange, metal wire-like growths. These are a symptom of his transformation into a Wire and his gradual loss of humanity. The Japanese website describes him as a "mystery man" with "eyes of madness".
He was Mondo Zappa's predecessor in the Bryan Execution Firm. As he carried out more and more missions, he became fascinated by the darkness and began to transform into a Wire. Because of this, Bryan sent Mondo to kill him. Damon accepted this, and warned Mondo about the dangers of the executioner job. After his death, he talked with Bryan at a table.
