Earth-53

Earth-53 is a reality in the multiverse. It is a divergent of real life in which Richard Nixon became President of the United States in 1960 instead of John F Kennedy.

History
Earth-53 was seemingly identical to Earth 95 and real life until Richard Nixon decided to wear make-up for the first televised presidential debate. This allowed him to make a better impression, and so the lead over Nixon that Kennedy normally got here does not happen, and Richard Nixon becomes President.

Unfortunately, when the Cuban Missile Crisis later hit, Nixon panicked and did not handle the crisis effectively, causing it to escalate into nuclear warfare, which saw the near total destruction of both the USA and the Soviet Union. And because of nuclear fallout, the rest of the Earth suffered as well. Much of Western Europe became destabilized, Eastern Europe was almost utterly destroyed with few survivors, and the USA likewise found itself reduced to a shadow of what it once was. There were survivors, but technology had been blasted back to the stagecoach era, while others showed signs of mutations in the face of so much exposure to radiation, leading to sterile but powerful superhuman mutates known as "Nuke-Men", "Radioactive Men", and "Omega Men". Miraculously, life still goes on on this Earth, but in a decidedly harsher state.

 * This Earth draws heavy inspiration from the video game series Fallout, as well as Earth-17 in DC's current multiverse.
