Sonic the Hedgehog, Vol. 13: Battle for the Empire (Sonic the Hedgehog (#13))

"Sonic and Tails duel a duo of dastardly doppelgängers in the series’ landmark 50th issue! Dr. Starline is behind the attack, but what’s his scheme?

After assembling a squad of bad guys, kidnapping Belle, starting a forest fire, and causing chaos in Central City, Starline is finally ready to unleash his monstrous imposters: Surge and Kit! Will his meticulous planning be enough to defeat Sonic and Dr. Eggman? And, in the wake of the climactic battle, both the heroes and bad guys need some time to heal and regroup… except Dr. Eggman, of course, who is always ready to destroy that darn hedgehog. Can Sonic, Tails, and Belle escape the city, or will Eggman finally bumble his way to victory? Definitive Sonic comics scribe Ian Flynn joins superstar artist Adam Bryce Thomas for a story more than four years in the making!
 
Then, it’s a little mangled, it’s kind of a jumble, it’s Rough & Tangle and Rouge & Tumble! Writers Evan Stanley & Gigi Dutreix, Aaron Hammerstrom, Daniel Barnes, Ian Mutchler, and India Swift join Ian to bring readers six new heartwarming stories of unlikely pairs.
