Oh man, there is some _beautiful_ irony to Furnace getting fucking scrapped the same way Sonic dies in the original story; by slamming backfirst into something while moving backwards.
This feels like a alternative alternative world to sonic where eggman just gave up and said "screw it, if I can't kill sonic with giant mechs and lasers, im just gonna have to *cook him*"
This isn’t a boss fight. This is vengeance. All the animals killed and cooked, all the friends you’ve lost. Everyone you’ve ever loved is now gone thanks to this…this…FURNACE! And now with the last survivor other than yourself gone, the furnace is after YOU!!! It’s time. You can’t hit him head on he’s too tough, you can’t throw stuff at him, he’ll dodge it. You’ll have to bait him into getting hit. But no matter what. The time of karma has come to strike. NOW KICK HIS ASS!!!!!
I feel like Fuenace would be even weaker to high speed collusions then metal tbh. And we all know what happens to metal in sonic cd. (SEVERELY DAMAGED BY A WALL.)
if you are going to add super sonic you should make a new form instead since there's like mods where he uses the chaos emeralds but sonic cd takes place before sonic 2 and sonic 2 was first introduced in sonic 2 so that would be cool if he can use the time stones as btw cool animaition
