Jonothon "Jono" Evan Starsmore, better known as Decibel or Chamber, is a fictional character, a Marvel Comics superhero associated with the X-Men and the New Warriors.
A British mutant, Jono possessed the ability to cast energy blast from his chest. He had limited control of his power and destroyed much of his chest and lower face when his powers emerged. Recently, he lost his powers on 'M Day' and now uses technology to give himself sonic based abilities.
Jono was a member of the X-Men’s junior team Generation X, although he was sullen and moody and had difficulty bonding with teammates. He was briefly a member of the X-Men as well.
Created by writer Scott Lobdell and artist Chris Bachalo, he first appeared in Generation X #1 (September 1994).
