Miss Sing

Yan Diushi (aka Miss Sing) is a supervillain and biochemical terrorist. This skilled and deadly scientist has no personal values or desires, designing and selling her chemicals to the highest bidder. She is often found on the peripherals of major villain team-ups, supplying the group with weapons of terrifying power before drifting away into obscurity.

Forgettability
Many of Miss Sing's formulas are designed to induce memory loss. Due to her long exposure to such chemicals, the scientist has a faint residue clinging to her body, particularly to her briefcase and mask. This can lead to those close to her being struck with a powerful but short-lived amnesia, meaning they might forget ever having seen her.

Briefcase
Miss Sing is rarely if ever seen without her featureless black briefcase. It is believed to contain her most valuable ingredients, chemicals and formulas, although those who witness it being opened rarely leave the encounter in a fit state to speak of its contents.
