Because, in the future sonic is the one who would stop evil and mephilis from his plans of destroying the world because the world did him wrong.
1st of all, you need to work on your spelling,2ndly Mephilis "knocks-out" Sonic, but gets regenerated by the Chaos Emeralds & with help from this one chick who kisses Sonic (on the LIPS lol).
It is not possible to hate sonic. he is unhatable he is god he is life
sonic likes amy not hate her
He doesn't hate her he just doesn't like her when she stalks him!
Dr. Eggman sets Silver on a mission to kill Sonic because he thinks that Sonic is the Ibilis Trigger, and therefore responsible for destroying their land. But on the inside he is a nice, friendly, cool, slightly softspoken boy who doesn't want to kill anyone and is an ordinary hedgehog, close to Sonic.That's not true! It was Mephilis who told Silver that Sonic was responsible for waking Iblis. Mephilis killed Sonic so that Elise would cry, setting Iblis free!However...everything else is true.
I myself Looove Sonic
Cheese
Beacause Sonic Cant Swim.
No, Shadow does not hate Sonic, but they aren't friends either. More like rivals.

No, they are friends.
