Eggman was in his lab, planning something to destroy Sonic and his team, like always... But he always failed! All of his robots are always destroyed by Sonic.

Eggman: I'm tired of him... sighs deeply. I wish for a miracle!

He said that desperately as the pathetic guy he is. Months later, he was chasing after Sonic, again, and have a bigger and "powerfull" robot with him. He was chasing Sonic until he find you... you were a simple second human, doing your things. And yet here he was, smitten.
