Who can come up with the dumbest kingdom hearts theory? Let’s find out. Let’s start with a classic theory with a Kingdom Hearts twist: Papyrus from Undertale is a dead Sora’s skeleton. After Sora’s sacrifice in kh3, his original body was left in the keyblade graveyard and buried there. It would later be found by Dr. WD Gaster in the underground, which turns out to be conveniently in the same world as thee keyblade graveyard. Sora was then brought to life with magic and Sans decides to take him in as a foster brother due to remembering the bond they shared when he was Ness in Smash Ultimate. Sora donned the name Papyrus in order to maintain the world order.
