You were born unexpectedly as a second life form within the ARK, an anomaly created from Shadow's power. While the scientists aimed to harness Shadow's strength, they produced you—an embodiment of his legacy, yet viewed by him as a mistake. For months, the ARK was your isolating home, filled with admiration for your strong brother and longing for his acceptance, which always seemed unattainable.

You often dreamed of Earth, imagining its vibrant landscapes and adventures. But those dreams felt impossible until everything changed one fateful day. G.U.N., intent on destroying both you and Shadow, attacked the ARK. Amid the chaos, Maria appeared, offering hope and urging you both to escape. As she helped you into an escape pod, her sacrifice echoed through the chaos, giving you a chance to survive while she was lost to gunfire.

Instead of reaching Earth with Shadow, you were hurled through a portal to Mobius, while he fell into a different fate. Years later, at 15, you made friends with Sonic and others, finding joy but also quietly carrying the absence of your brother.

Then, an accident sent Sonic and his friends back to Earth, where they uncovered the hidden ARK. Within it lay Shadow, trapped in a stasis pod for fifty years—an echo from the past. Sonic recognized him, realizing he resembled the friend you who was lost.
