Scp death battle story

O5-5 SCP Foundation

Mortimer J. Denning Von Kronecker was a boy born in London during the era of the Black Plague. In his universe the plague has caused far greater devastation and famine than what we know in history today. In his universe, a doctor claimed to have the cure for the plague, but it became apparent the plague he was trying to cure was not the plague everyone had expected. Over time the terrible monstrosities created by the doctor spread throughout the world, destroying entire countries until only London was left. It was at this point, Mortimer heard a voice, calling for him from another universe. It was himself. It was then that he and himself searched through every universe until they had all found one another, and there was no one else to find. Reaching the point all the Mortimer formed a pact and became a single being. Should a single version of them die, another one takes over their place. Using their new found immortality, Mortimer sought to make his life better for everyone he met. Least they end up the same fate his homeland did.
