Show a gigantic, fairy dinosaur named Nerathor the Destroyer

Show a gigantic, fairy dinosaur named Nerathor the Destroyer. He should have a massive T-Rex-like head, with spiky, covered with dark scales. His eyes are deep black with red glowing points, which underline his threatening charisma. The dinosaur's body is about 20 meters long and covered with shiny black scales, which absorb light and occasionally have purple or red highlights. He has big ones, dark wings with cracked membranes, that unleash a storm of shadows and magical energy. His tail ends in a heavy, club-like structure, which is riddled with sharp thorns and dark magic. The scene should appear threatening and imposing, to underline Nerathor’s role as a powerful apex predator and destroyer.
