Frequencia knows what she wants to have — obscene amounts of riches — and how she wants to obtain it — while laughing her feathers off at any attempt too incompetent to stop her. To make all that come true, she and her henchmen have developed a sound machine capable of producing such a noise that anyone hearing it just mentally fries down for a good few hours if left unassisted. Frequencia's crew isn't immune to the effects either, but it's nothing a good pair of earmuffs can't solve. What earmuffs don't solve is Frequencia's need to gloat and show off her crime spree. She gets a kick out of announcing her plans and watching people futilely try to apprehend her or safeguard her intended loot. There's only so long before this comes back to bite her, but that's not a thought Frequencia is willing to entertain.
