I didn't have time to add all the details.

It's how sonic and shadow go into a portal and meet a new person named spider-man.

Sonic is bitten by the same spider that bit Peter Parker was bitten by, who is now in an old folk's home. Sonic runs into Peter Parker and he gives Sonic his old suit. And now Sonic is the new Spider Man, or should I say Spider Hedgehog. P.S. this is obviously and it is a sonamy story.

Stan "Sonic" Parker is your average geek. When he gets bitten by a special Spider, he gains powers! And half of his friends turn on him... Minor Sonamy. Somewhere.
