A high-quality anime illustration of Proto Arthur, depicted in a medium shot from a slightly low-angle perspective. Proto Arthur is a handsome young man with short, neatly styled blonde hair and determined blue eyes, wearing his signature ornate white and gold royal armor with a high collar and a flowing blue cape draped over his shoulders. He stands in a dignified posture, his right hand firmly gripping the hilt of the legendary sword Excalibur, which is pointed slightly downward, while his left hand is clenched in a focused fist by his side. The background is a dramatic battlefield under a stormy sky, with shattered stone ruins and swirling gusts of wind scattered across the desolate terrain. The visual style is characterized by sharp line art, dramatic cinematic lighting with high contrast, and a color palette of brilliant golds and deep blues, creating an epic and heroic atmosphere with floating dust particles and a sense of immense power.
