Preheat the oven to 375 F. In a small bowl, stir together the ground turkey, plain bread crumbs, garlic powder, paprika, red pepper flakes and parsley until completely combined. Spread the mixture out onto a greased, foiled lined baking sheet and form into the "face" of a demogorgon.
In another bowl, stir together the sriracha ketchup, Worcestershire sauce, garlic powder and maple syrup. Arrange the strips of bacon in a circle around the center of the "face" to separate the "petals" from the mouth-hole of the demogorgon. Brush the entire meatloaf with the sauce.
Press 1/2 inch length pieces of onion into the meatloaf in the pattern of a demogorgon's teeth. Cover the meat load with foil and bake for 25 minutes. Uncover, brush on the remaining sauce, and cook uncovered for another 10 minutes.
Use the foil beneath the meatloaf to push up the "petals" so it looks like the open mouth of the demogorgon. Serve hot along with some Eggo waffles and extra spicy ketchup. Enjoy in the Upsidedown while binging Stranger Things.
