Demonic Entity Portrait with Golden Energy

Epic cinematic portrait of a colossal ancient demonic entity, extremely powerful villain. Tall muscular humanoid figure with dark obsidian-like cracked skin, glowing crimson-gold light seeping through the cracks like inner fire. Calm serene face with glowing solid golden eyes, no pupils, unsettling stillness amid chaos. Massive visible aura of dark golden energy distorting the air around him like heat waves. Torn dark cloak violently flowing from the energy output. The ground beneath him is cracked and shattered, rocks and debris levitating around him from sheer power. Fragmented glowing cursed symbols floating and dissolving in the air near him. Dramatic low-angle shot emphasizing scale and power, dark stormy background with lightning, intense rim lighting from his own energy, semi-realistic cinematic concept art style, hyper detailed, movie poster quality, 4k, epic atmosphere.
