What would happen if, on Sonic's 16th birthday, he and his friends—Tails, Knuckles, Amy, Rouge, Blaze, Silver, and Shadow—found themselves in the midst of a fierce confrontation with a new and formidable villain named Wizard Skilo? As they battled, the air thick with tension and the sounds of their clash echoing through the landscape, Skilo unleashed something that sent a chill down their spines: a dark orb, pulsating with an ominous energy.

Sonic and his friends stared at the orb, struggling to comprehend its significance. It was unlike anything they had encountered before, a dark sphere that seemed to absorb light and hope. However, there was one individual who immediately recognized its horrifying potential—Eggman. The notorious villain's face drained of color, a look of sheer disbelief crossing his features. He was horrified by the revelation that this orb was not merely a trinket of dark magic but a powerful object that sealed away the ghouls. These were the malevolent spirits that had instigated a cataclysmic war 45 years ago, turning what was once a thriving world into the desolate wasteland of Mobius that they now knew.
