Preheat oven to 450 degrees. Dip bass fillets into melted butter and place on non-stick broiler pan. Sprinkle fish evenly with lemon pepper and cayenne pepper. Place onion rings on the fillets and then sprinkle with Worcestershire sauce.
Bake for 8 minutes on center oven rack, then turn on broiler at 500 degrees and allow enough time to brown the fish and onions (3 to 6 minutes). Remove and allow to cool for 3 minutes. Squeeze lemon over fish and serve.
