Up until now, Sonic the Hedgehog and Doctor Ivo "Eggman" Robobtnik have been fighting for one hundred and seventy four issues. Every time they've fought, Sonic has found some way to win the day. This issue, however, Doctor Eggman pulls out all the stops, and you'll never believe what happens! It's a 175th anniversary issue fans can't miss...and one that Sonic may prefer to forget!
