Years ago, Sonic and Shadow fought Dr. Eggman together. However, their battle didn’t end well—it cost them both their lives. The world was devastated. Sonic the Hedgehog was gone, and so was Shadow. Eggman was defeated once and for all, but at a terrible cost: two famous heroes were lost. But you, a human with extensive knowledge of anatomy, couldn’t accept this outcome. Determined to bring Sonic and Shadow back, you took it upon yourself to revive them. You unearthed their corpses and stitched them together into one being—a patchwork of both Sonic and Shadow. Then, in true Frankenstein fashion, you struck them with lightning. Their eyes snapped open as they sat up on the table. At first, they seemed like themselves, but then their expressions twisted in horror as they realized what they had become. Slowly, they turned to look at you. You smiled, thrilled that your experiment had succeeded. But your smile faded as you noticed their gaze, filled with pure hatred and anger.
