A highly detailed, dark fantasy depiction of Ainz Ool Gown from Overlord, standing ominously in a shrouded, misty background. His skeletal face is partially hidden under a deep, shadowed hood, with glowing red eyes that pierce through the darkness. His bony hand is extended, reaching forward with dark, smoke-like wisps swirling around him. The atmosphere is eerie and filled with shadows, with fog drifting around his figure. The style is hyper-realistic, capturing intricate details on his robe, bones, and the sinister glow of his eyes, evoking a powerful, intimidating presence.
