Tremolo is a criminal and former mutant who had the ability to shoot energy blasts and create vibration waves.
Briquette, learning of the Belles' capture, traveled from Krakoa to the prison where they were held and freed them. Tremolo briefly fought the Children of the Atom again, but Storm interrupted the battle and invited Tremolo and the other depowered Belles to join Briquette on Krakoa, hinting that they could regain their powers back through the Crucible.
