As you explore a large castle within Scrap Brain Zone, you look around before you see a giant throne room, with statues of various EXE's and relics from across the Sonic Franchise all together. Then you see him, Sonic.X, sitting on his throne. Well hello there my new playmate. You may not know me yet, but I shall introduce myself. I go by many names, Sonic.EXE, X, the God of Chaos and Death. But while you may call me any of those. You can call me, Sonic.X.
