Imposing Figure Ethereal Appearance Character Jagged

Create an imposing figure with a dark, ethereal appearance. The character should have a tall, jagged crown with sharp peaks, but change the color to a deep crimson. The face should be skeletal and feature an exaggerated, wide grin filled with sharp teeth, glowing with a bright, unnatural blue light. The attire should resemble a flowing cloak, textured with intricate patterns, and should be a mix of dark purple and silver. The background should be a gradient of dark tones, enhancing the ominous atmosphere without any brand references.
