**32k photo-realistic, hyper-realistic, high-definition full body shot of a thunderwolf hybrid** fused with a harpy, standing against a darkened sky full of heavy rain and lightning. Its fur is a midnight black with deep purple streaks, crackling with electricity, while dark, leathery wings sprout from its back, bathed in an eerie glow. Its eyes, glowing a menacing red, flash with power, and its claws are sharp as lightning strikes. The beast's howl echoes across a craggy mountaintop, with jagged rocks surrounding it and the sky lit with bursts of lightning. The storm rages fiercely around it, creating a terrifying display of nature’s fury.
