Create a realistic and futuristic full-body portrait of a character inspired by Plasmus from DC Comics, displayed in a portrait orientation. The character is known for his amorphous, plasma-like body. The futuristic version should have a slick and flowing form that seems to be made of a semi-solid substance, with a color scheme that reflects his unstable and toxic nature, typically in shades of purple and red. The design may include glowing fissures or areas that suggest intense internal energy. His posture is menacing and amorphous, capturing the essence of his malleable and destructive abilities. The background can be an urban environment, showing signs of corrosion or damage caused by his powers. The overall design should evoke a sense of danger and unpredictability associated with Plasmus.
