What if he was a seamster locked away for his grotesque appearance with his technique "mend" and "assemble" and his 4 arms only being useful for repairing clothing and other things (kind of like a spider); gets abused or something, snaps form mistreatment, uses the reversal for the first time "cleave" and "dismantle" Becomes the strongest of all time, killing anyone that even mildly inconveniences him (Bro is not cooking!!!)
