Beelzebub appears as a towering humanoid with dark, leathery skin, exuding an aura of decay and malevolence. His face is sharp and angular, with glowing red eyes and a crown of twisted, charred horns. Large, tattered wings protrude from his back, their once-majestic feathers now blackened and withered. His fingers are long, tipped with razor-sharp claws, and his mouth curls into a sinister grin, revealing sharp, jagged teeth. Shadows seem to swirl around him, distorting the air.
