Let me kill him this time

That was all Sonic said when he and Ivo ended up in this dark universe, one razed and burned by a crazed Oliver. An Oliver who went mad from his loss after the events of Sonic 2. One who, upon tasting the flesh of a Mobian, wanted more. Building a new Metal Sonic, named "Furnace", he would tear apart the Freedom Fighters when they arrived on Little Planet, burning their world, and dancing in joy at his victory, which was almost cut short by his world's Ivo, who failed to kill him, being killed by Furnace instead.

If you couldn't tell, the Starved Robotnik au is being included... also NGL, that image of Robotnik creeps me out.
