Special 10-year anniversary issue featuring an all-star artist jam. The celebration of Sonic's 10th Anniversary in comics might also be the beginning of the end for the blue blur, his friends and their enemies as well. The action picks up from the previous issue; Shadow returned to help in the fight against the alien Xorda who want nothing more than the destruction of Mobius. After reasoning and bargaining fail, the denizens of the planet must band together for their very survival! In the end, a hero will fall and the future of Mobius will be changed forever.
