A more realistic portrayal of a supervillain inspired by the Aquarius zodiac sign, named Frost Flow. This character has the ability to manipulate ice and cold, with a more grounded and realistic costume design that subtly incorporates elements of ice and frost. The appearance should be less quirky, focusing on a practical yet unique design that suggests their mastery of cold elements. The character is shown in a full-body pose, with more subtle and realistic ice and frost effects, perhaps with a light icy mist surrounding them. The background should be a realistically depicted frozen landscape, complementing their ice-manipulating abilities. The character can be either male or female, with a posture that is confident and commanding, reflecting a more realistic interpretation of the Aquarius essence.
