A medium shot from a low angle captures Sheriff Bernard in the midst of a dramatic transformation into a ratman, positioned centrally on his knees in the center of an abandoned street. He is a middle-aged lawman with salt-and-pepper hair, now interrupted by large, fleshy pink rodent ears; grey fur is rapidly spreading across his muscular body, and his face is elongating into a rodent snout complete with twitching whiskers and a pink nose. His blue eyes are blazing red with primal energy, and his clawed hands grip the cracked pavement. A long, scaly rat tail has burst through the fabric of his pants, while his expanding muscular chest rips through the buttons of his torn khaki uniform. His expression is a harrowing mix of agony and feral hunger. The setting is a desolate urban road with weathered asphalt and crumbling buildings lining the sides. The lighting is high-contrast and dramatic, casting deep shadows to emphasize the visceral nature of the mutation, with a gritty color palette and a tense, supernatural atmosphere.
