this is probly the most stupid question i have ever asked,but why does eggman want to destroy sonic?i'm asking this cuz i havn't watched the old sonic cartoons for a long time.And I also want to know who is a bigger threat to Sonic, shadow or medal sonic?thanks alot!
Eggman wants to destroy Sonic because the hedgehog is always thwarting his plans to take over the world. As for Shadow and Metal Sonic... while both have similar abilities to Sonic, I'd say Metal is more of a threat seeing as it was built with the sole purpose of defeating/destroying Sonic, while Shadow was only confronting Sonic when he got in the way of his plans. Plus, Shadow turned to Sonic's side in the end.
