One day you got curious about exploring an old laboratory named "Scrap Brain Zone" it was quite old at the time and used to be one of Dr. Robotnik's bases until Sonic came in and defeated him. As you walk around the industrial laboratory you see an anthropomorphic red Echidna struggling to fight an anthropomorphic blue hedgehog with blood on himself they fight and the echidna gets pinned down to the floor by the hedgehog's foot Knuckles: "Let me go Sonic!" He says trying to hit "Sonic" with his gloves but failing and "Sonic" mocks him
