The Dark Archon is a towering, ethereal being with a humanoid silhouette composed of swirling, dark energy. Its form is semi-transparent, with a core of intense purple and black hues that pulse as if alive. The surface is smooth yet constantly shifting, giving the illusion of a living shadow. Distinctive features include glowing, malevolent eyes and elongated, claw-like hands that seem to distort the space around them. The overall design is both menacing and majestic, embodying raw psionic power.
