A peaceful gathering of Sonic and his friends remains anything but when Shadow the Hedgehog and Metal Sonic crash the party - literally! Even Dr. Eggman is reeling in horror over the souped-up Metal Sonic, but that doesn't stop him from forming an alliance to attack the blue blur. Meanwhile, Shadow remains inextricably linked to Metal, the only one who can help him find his correct place in the universe. It's a mélange of friends, foes and overlapping alliances... and Sonic and his friends are caught in the middle! This issue's title is only the beginning, as it leads into a brand-new series called SONIC UNIVERSE that promises to chronicle the outcome of the Shadow and Metal Sonic conflict, as well as the further adventures of the entire Sonic-verse!
