Ms. Decibel originated from a wealthy British family, where she sought out her dream of being a musical prodigy, particularly trumpet playing. When given her big chance, she was booed for her horrible performance. During said performance, however, the trumpet became (seemingly permanently) wedged inside her trunk. However, the tones emitted through her entrapped instrument had a hypnotic effect on her audience. This prompted Ms. Decibel to seek a life of crime, effortlessly taking control over anyone in her path.
