While searching for the Earth 3 Marcus, Farcus they met the Marcus that started it all from the sonic original universe. They question why would Farcus try to to kill the original Marcus but then they realize you can't kill the original and erase all Marcus's in the universe but to truly kill off Marcus is to destroy the universe.
Every choice and decision a person makes creates an alternate universe.
I chose the sonic forces story as the prime universe for all sonic fan characters is because all fan characters are made and created and when fanart of that character is made it creates a universe for that character thous is the prime universe.
