Book Description

"When Hedgehogs Collide": The return of the Anti-Sonic! And this time he's brought friends... The Anti-Sonic is looking for some action, so he rounds up the "gang" consisting of the Anti-Sally, the Anti-Tails, the Anti-Rotor and the Anti-Antoine! They then take the Cosmic Interstate to Mobius, dress like their counterparts and steadily proceed to terrorize the Mobian countryside! So where have the Good Guys been all this time? Sonic, Tails and Antoine had been sent by Rotor into "negative reality" though they were unable to penetrate "the Zone of Silence" (aka, The Void) where Sally's father is being held. Sally's been out on a mission with the trainees. And everyone arrives back in time only to have their fellow Mobians terrorize them! However an attempt to confront the Anti-Freedom Fighters turns into a draw until Sally realizes that there's no way they can defeat their other selves, who would be able to anticipate their strategies. So how do they propose to beat the snot out of them?
