Lamplighter is an original member of the Seven. His true name is unknown, but much like all supes, his powers derive from Compound V. In the 9/11 incident, he suffered some damage in both ribs and lungs when being hit by a plane's wing. Afterword, The Boys tried to blackmail The Seven with the truth of 9/11. Angered by this, Lamplighter kills Mallory's granddaughters. His own team gave him to the Boys to as a peace offering to prevent a violent conflict between the Seven and the CIA. The Boys beat him to near death before Malory shoots him in the head, but he was revived to a zombie-like state, thanks to the Compound V, and hidden beneath the Seven's headquarters, playing in his own feces. Vought occasionally uses him to show the public that they are stronger than death. He was replaced by Starlight.
