She wears a form-fitting outfit that blends armor panels with fabric cloth, featuring sharp edges and intricate line work that highlight her Alter Ego aesthetic. The figure captures dynamic movement, with a swirling cape-like accent and a crystalline pedestal that evokes a fractured, magical aura. Subtle color shading across her costume emphasizes texture, from glossy highlights on metallic surfaces to soft gradients in her skin tone. The overall presentation conveys mischief, power, and a mysterious presence.
