Create a massive ogre in A-pose, a hulking brute with mottled, rock-like skin and an enormous frame. His crude, spiked armor is pieced together from shattered shields and scavenged metal, adorned with hanging chains and skulls. He grips a giant club made from a petrified tree, its surface covered in glowing runes. His small, glowing yellow eyes gleam with savage intelligence. Render in ultra-detailed 8K, photorealistic, octane render, Unreal Engine-ready, cinematic masterpiece.
