Max Boldd was a rich kid who grew up getting thrown out of all the right schools along with her friend Lou Jacks. For reasons unknown she turned to crime and became the crime czar known as Vendetta.
Vendetta had somehow obtained some of the technology left behind by the Others and discovered how to use it for creating super-beings. She used the technology to create Vort-X and gathered a team of mercenaries named The Regulators.
Things didn't work out with The Regulators. After Vort-X's son was kidnapped the team left Vendetta to work for themselves. Vendetta was last seen when she revealed that Hardedge tried to have her killed, but she remained active and made a point out of spoiling the Regulator's jobs.
Notes: In Shadowhawk (2005), she is shown as having a lesbian relationship with Vort-X.
