Resident Evil Pikachu

Imagine a small, cute creature associated with electricity, undergoing a fictional transformation that often causes grotesque mutations, resulting in a terrifying fusion of its original charm and horrifying changes. Its previously bright, yellowish fur is now splotched with gloomy patches, the eyes are blood-red, and its cheeks bulge with throbbing veins. The creature's inherent electrical capabilities have seemingly intensified, making it an intimidating adversary. Render this in a hyperrealistic style as a splash concept art, providing intricate details. Highlight the 2/3 angle of the creature's face with side lighting. Use a colorful background to further add depth and drama to the portrayal.
