Sonic the Hedgehog #161

"Birthday Bash - Part Two": Continuing the chaos begun last issue, Sonic’s fifteenth anniversary year… and his birthday party… kick into hyperdrive! An attempt to steal the Master Emerald goes wrong… Rouge’s new accomplice Evil Sonic is transformed into a souped-up speed demon and renames himself Scourge… and if all that’s not enough, things get even worse for Sonic as a long lost badnik from the early days comes back with a dangerous new twist! It’s a birthday full of “presents” Sonic would rather return!
