Design an extremely powerful demonic creature. It should have large, menacing horns, glowing red eyes, and a mouth filled with sharp, jagged teeth. The creature's body should be massive and muscular, covered in dark, scaly skin. Include features like spiked armor, enormous clawed hands and feet, bat-like tattered wings, and a long, barbed tail. The overall appearance should convey immense strength and pure malevolence, striking terror into all who behold it.
