In the past, Shadow once tried to destroy Sonic, as well as the entire planet, but was eventually reformed. This led to Shadow teaming up with Sonic, Tails, Knuckles, Rouge, and even Dr. Eggman himself to save the world.[5] After that, he played a part in the war against the invading Black Arms. Eventually, Shadow was forgiven for his misdeeds and now actively seeks to protect the world.[6][7] Shadow has even fought Sonic on a few occasions after their first meeting[8][9] Shadow would later participate in the world grand prix with Rouge.[10]
