A large, vibrant mural is prominently displayed on the weathered concrete exterior of a cooling tower belonging to the "Sofia" Thermal Power Plant (TEC Sofia) in Sofia, Bulgaria. The mural depicts a monstrous, muscular humanoid creature with purplish-red skin, glowing white eyes, and a long, extended tongue. It wears torn grey garments. The creature brandishes a large, metallic, serrated axe or cleaver over its right shoulder, featuring an attached syringe filled with orange liquid. In its left hand, it grips a metallic pipe-like object emitting a yellow-orange burst of flame or energy. Below the figure, stylized graffiti text reads "Dr!Mest" in multi-colored block letters, with "salutes you" in yellow script underneath, and "RUSH" in smaller characters at the bottom right. The mural's background is rendered to resemble cracked, earthy ground. Bare deciduous tree branches partially frame the lower section of the artwork. The upper right portion of the image reveals a clear blue sky adjacent to the cooling tower.
