Somewhere far from the known universes in Zen-Oh's domain...there exists a plane outside of the multiverse not known by anyone. Within this plane, there exist multiple dimensions and universes held within what some have theorized to be bubbles in a vast ocean of infinite number. These universes have been lost to time and memory by anyone outside of their borders.
Was it fate...or the will of the universe itself, that this tradition was broken? Long ago it was suggested by ancient storytellers...and after that scientists...that two universes could be similar enough that they could mesh well together. There was always the possibility...that a bubble might float away from the ocean it inhabited with so many others...and be guided to somewhere far away where it's destined mate waited...and called to it.
The journey would take several centuries to complete, it began during its own Earth's birth, before Krypton even. Unknown to any of its inhabitants it made this journey.
The Green Lantern Corps were established by the Guardians of the Universe.
Doomed planet.
Countless lifetimes later Krypton's core had become unstable...it was only a matter of time before the planet destroyed itself.
General Dru-Zod and his forces would attempt a coup and be locked away in the Phantom Zone.
Frieza would order the slaughter of the Saiyan race...
Desperate scientists.
Jor-El and Lara Lor-Van would send their infant son rocketing across the stars to a faraway planet called Earth as their home exploded around them.
Bardock would face Frieza alone..and be destroyed along with Planet Vegeta.
Kindly couple.
The Saiyan infant named Kakarot would be found by Gohan in a space pod, be given the name Goku...later suffering a head injury and erase all memory of his Saiyan lineage and mission.
The spaceship containing Kal-El would land outside the Kent farm in Kansas, and the baby within would be adopted by Martha and Jonathan Kent and later be named Clark.
Though time flowed differently in Universe Seven than it did within Universe Prime...it was almost uncanny how these two men who shared so much in common...seemed to arrive on their respective Earths in the same fashion and mere moments apart.
Perhaps it truly was fate's guiding hand that they were destined to meet.
