Elliot S! Maggin was fond of this sort of thing for Superman. He revealed that
1) Among every single known species in the universe, no matter their language, their name for Superman is pronounced "Superman" (those specific three syllables).
2) Superman was the result of a secret eugenics program by the Guardians of the Universe to create the ultimate Green Lantern who would one day take over for the Guardians.
3) The Big Bang created a chunk of matter that coalesced into a sword with the familiar S-symbol on its hilt. Superman was destined to one day pick up this sword, at which point he would achieve omnipotence.
