One day, Sonic was running along Green Hill when he noticed a badnik (One of Robotnik's robots) had malfunctioned and blew up. The Flicky inside it was dead. Sonic tried to ignore it but kept wondering, is it edible? Curiosity got the best of him as he picked it up, and ate it. Once he had a taste, he needed MORE. He stopped eating chili dogs and started eating his own animal buddies. His teeth looked horrendous, half of it had fallen out due to how much buddies he ate, and the rest was blood-stained, sharp, and almost completely rotted. Sonic resorted to wearing a bandanna, but it was worn, with small patches visibly showing his disgusting teeth. His eyes became bloodshot as he never slept, looking hollow. Eventually, he had eaten all the buddies, and he was still hungry. He went after Tails, ripped out his organs, ate his eyes, and tore both his hands off. Next was Robotnik. Ripped his entire head off and ate it. He threw all the leftovers in the sea, making it red with blood. Next was knuckles. He tore off one of Knuckle's hands but, he survived. Knuckles punched him so hard in the mouth, he knocked Sonic's bandanna off. Knuckles ran as fast as he could. Sonic attacked Knuckles, but Metal Sonic stopped him. Sonic ripped at him, clawed, but Metal punched him, knocking him into the river, but Sonic grabbed Metal's leg as he drowned, killing him as well....
Stafoon- for rigs I just realized that this is just Shin Sonic but more natural
