A striking fantasy illustration of a fierce, armored warrior riding a monstrous, demonic creature. The warrior is muscular, adorned with intricate, glowing red tattoos, and dons a horned helmet, exuding an aura of power. He wields a massive, double-bladed flaming axe, and his gray beard and hair amplify his imposing presence. The beast he commands boasts a metallic, armored hide, adorned with swirling patterns. Its eyes, mouth, and hooves burn with fiery orange light, casting a hellish glow. The stormy backdrop, with dark clouds and crackling lightning, heightens the apocalyptic atmosphere, as the scene crackles with raw, untamed energy.
