Cynthia Moore operates as a professional con artist and key member of Team Confidence. She stands 5'7" (170 cm) tall with long red hair and striking purple eyes, typically dressed in a beige jacket over a blue dress shirt, black pants, and black or white shoes, occasionally accessorizing with glasses.

Before her life of deception, Cynthia worked in a café while pursuing dreams of stage acting. There, she met Thomas Meyer, a regular customer. Their romantic relationship led to cohabitation amid financial struggles, with Thomas painting her portraits as he sought recognition as an artist. Their bond fractured when art appraiser James Coleman enlisted Thomas to forge paintings, shifting his focus to profit over originality. This betrayal cemented Cynthia’s enduring disdain for artists and the art world.

Confident and intelligent, Cynthia leverages her theatrical background to remain unflappable under pressure, excelling at improvisation and employing her sex appeal strategically during cons. Fluent in multiple languages, she adapts effortlessly to dynamic situations. She rejects the label "cougar" and radiates a vibrant, youthful energy despite being in her 40s.

Her criminal career ignited after a failed attempt to scam Laurent Thierry in a bar; he uncovered her ruse and recruited her into his crew.

In Team Confidence’s operations, Cynthia assumes pivotal roles. During the Los Angeles Connection scheme, she impersonated FBI investigator Paula Dickens to manipulate Makoto Edamura and advance the plot against drug trafficker Eddie Cassano. For the Singapore Sky mission, she posed as manager of an all-woman aviation team alongside Abigail Jones, infiltrating a rigged air race.
