Sonic The Hedgehog #91

Burning hot with power, Blaze the Cat has lost control of her mind to the conniving Blackwood the Ermine, who commands her to hunt and battle Silver the Hedgehog. Now, Silver and his new companion Dapple must race through the ever-changing hallways of the Castle Colossus to stop Blackwood, save Blaze, and free the townspeople trapped as servants!

With the very ground they step on working against them, can our heroes save the day this time? This spooky arc on the Road to #100 closes with a dramatic issue focused on fan favorites Silver and Blaze!
