i changed his design a bit and im changing his story too
at least the start of it
he is still the vessel of a "god" (chaos pearl) but he is himself as well as being said "god"
chaos pearl lost his memory after taking over saturns body and has been living as him for the last 20 years (thats how old saturns body is)
saturn doesnt know hes basically a god
reminder saturn is in a different universe than sonic, meaning theres a 'sonic' (neptune) in saturns universe
