A formidable demon clad in intricate black and red armor integrates chains into his attire, channeling ancient dark magic. His form is partially shrouded in flowing cloaks of deep crimson and shadowy black, blending seamlessly into his surroundings. Atop his armored figure, instead of a conventional head, a swirling sphere of ominous red energy pulsates with an unsettling glow. This visual entity, rendered in stunning 4k ultra realism, captures the essence of legendary fantasy worlds akin to those in Lord of the Rings and Dungeons and Dragons. The demon's presence commands awe and dread, as if he has emerged from the deepest realms of myth, invoking a chilling blend of fearsome power and dark majesty.
