Backstory

Due to me joining before the rule 2 incident, I had to change the backstory, so I decided to explain both here

Before:the timeline follow the usual timeline from the starved eggman ,up to eggman's death due to tail, despite what happens,the remaining living being get decimated by furnace or other robot,living this universe as one empty world,until furnace found a strange rock,which teleported him to the umaverse,after that he kept his old antics,commiting multiples murder before being stopped by metal,reprogrammed by an unknown person,and deciding to stay at Tracen due to it being the place where metal reside

After:furnace was created on an isolated island by Dr Robotnik,a scientist who exiled himself due to his strange passion for sentient robot, due to the boat ressuplying the doctor with food sinking , he ended up starving, modifying one of his best robot into furnace, instructing him to start hunting every animal trought the island and cook them to feed him, after multiple months , he hunted every animal on the island to extinction,not managing to stop his creator from starving, he then set out to the sea, ressuplying on island until reaching main land japan

Common story:(despite both backstory being different, this part is common to both)

Upon reaching main land japan he continued hunting down animals for food, even going as far as hunting human and umas, even though the latter was much harder to kill

Upon being found by metal, furnace recognise the code as similar to the one used by his creator, but continue to obey, after his destruction, an unknown scientist took his remain,reprogramming what he could of furnace into a more protective oriented robot, although due to his construction,his source of energy produced heat in the center of his body, causing flamme to burst

After the reprogrammation furnace personality went from silent, emotionless and very robotic to more enthusiastic, willing to help and can be very talkative, although he tend to get more cold the more serious he get

That's all, just wanted to share the backstory
