Chamber (Jonothon Evan Starsmore) is a superhero appearing in American comic books published by Marvel Comics. The character is usually associated with the X-Men and the New Warriors. A British mutant, Jono possessed the ability to cast energy blasts from his chest. He had limited control of his power and destroyed much of his chest and lower face when his powers emerged. He lost his powers on M-Day. For a time he used technology to give himself sonic based abilities. He regained his powers after the events of Age of X. Jonothon was a member of the X-Men junior team Generation X. He was sullen and moody and had difficulty bonding with teammates. He has since been offered a permanent position in the X-Men's teaching staff. Publication history Created by writer Scott Lobdell and artist Chris Bachalo, he first appeared in Generation X #1 (November 1994). Fictional character biography Origin Jonothon Evan Starsmore ("Jono" to his friends) is a native of London and a mutant who possesses a furnace of psionic energy in his chest. This power first manifested in an explosion during a party he was attending with then girlfriend Gayle Edgerton. Its initial manifestation destroyed much of his chest and lower face and crippled Gayle. As a result of his disfiguration, Jono can only speak via telepathy. He does not eat, drink, or breathe; it is believed that either the psionic energy sustains him without needing his vital organs, or that his body is merely a shell, and he is actually made up of psionic energy. This is further supported by the fact that Jono is immune to the "Death Factor" of Omega Red, meaning that he is not sustained by "life force". The primary manifestation of his abilities is his ability to fire powerful blasts of psionic force. It has been implied at numerous times that Jono is potentially one of the most powerful mutants to walk the earth (most notably the scale of his mutagenic aura as seen by Emplate in Generation X #1, also at times when he is seen to 'cut loose' with his abilities) but his emotional issues have apparently prevented him from significantly exploring this potential. His disfiguration also left Jono sullen and angry and his teammates have often found him difficult to get along with. Generation X Shortly after his mutant powers manifested, Jonothon accepted an invitation to join Xavier's School
