Preheat the oven to 475 degrees and line a baking sheet with parchment paper.
Roll or stretch the pizza dough into a rough skull shape about 12 inches long on the prepared sheet. Press lightly to define the forehead, eye sockets, and jawline.
Brush the entire surface with olive oil and sprinkle evenly with garlic powder.
Mix the mozzarella, provolone, parmesan, and asiago cheeses in a bowl, then spread them evenly over the dough, keeping the cheese inside the skull outline.
Bake for 12 to 15 minutes until the crust is golden and the cheese is fully melted and bubbly.
Remove from the oven and let the pizza rest for 3 minutes before slicing.
