History:

(X-Factor I#79 (fb) - BTS) - The Belles worked alongside Cyber for an unnamed major drug cartel. When teammate Shrew quit and made a deal to testify against the cartel in exchange for immunity against prosecution, the other Belles were sent to kill her. The US government assigned X-Factor to protect Shrew.
    Cyber ambushed Polaris, beating her, breaking her jaw, and sending her to the hospital.

(X-Factor I#80) - Flambé forced a government agent to tell her where Shrew was being hidden, after which she killed him. The Belles them ambushed Shrew, Havok, Strong Guy, and Wolfsbane in the Barclay Hotel in Virginia. Wolfsbane caught Vague's sent and exposed her, but Flambé stopped Wolfsbane and Havok from chasing her. Briquette confronted Strong Guy, and their fight carried them through the floor, all the way to the basement, leaving Shrew to face Tremolo. Though Strong Guy recovered more quickly than Briquette, Cyber then exposed him to a lethal poison.

(X-Factor I#81) - The basement boiler exploded due to contact with Briquette, and both groups fled. Cyber instructed them to surrender Shrew or else he would not give the antidote to the poison, but a US toxicologist managed to cure him. X-Factor (joined by Multiple Man and Quicksilver) met Cyber and the Belles at his instructed meeting place. X-Factor overpowered the Belles, and Shrew knocked Cyber into the path of an oncoming train.

(New Avengers#16-19 - BTS) - Flambé, Tremolo and Vague lost their powers on M-Day and the energies removed from them were combined with a number of other mutant energies to empower the powerful being Michael.
