First of all that's not how, when or why Shadow was created. Second of all no one at the time knew about Sonic, because he wouldn't be born until 40 years later, and at that time no one knew about Sadow because he wouldn't be released from Carbonite until 10 years later. Lastly, Sonic doesn't have all the same powers as Shadow. Sonic has super speed, Spindash, homing attack, etc. shadow has chaos powers, Black arms blood and the Spears.
