Craft a futuristic, full-body portrait of Atomica from DC Comics. The character should be displayed in a realistic style, with a sleek, advanced suit that hints at her ability to shrink to microscopic sizes. The suit could incorporate nanotechnology patterns and a color scheme that reflects her villainous nature, such as dark hues with accents of brighter colors that suggest her energy and treacherous abilities. Her pose is cunning and confident, reflecting her deceptive personality. The background should be high-tech, perhaps with visual elements that play with scale to emphasize her shrinking powers, symbolizing the futuristic world where she enacts her plans.
