So I’m sure every one has heard about the theory about silver being shadow son from the future, but that would not make sense since silver is born 200 years later from main sonic timeline. so that would cross out Amy, Rouge, being the mother etc
The only possible explanation Is Eggman Descendant like Eggman Nega for example. For whatever reason Eggman descendant could not locate shadow, But he did come upon shadow dna that was most likely stored in the ark or GUN.
wanting to follow in Gerald Footsteps at having a ultimate lifeform as a weapon,since he could not find shadow and use him(most likely shadow had been sealed away) He took Shadow dna that had been stored away,and used it to create Silver. Along with tweaking the dna (he could have used a unknown female parent dna along with shadow.
Notice how Silver can use Chaos energy just like Shadow?
I’m guessing at some point, Once Silver was completed, Silver did not live up to eggman nega expectations as he most likely did not want to hurt others. or be a weapon for eggman nega. At some point while escaping from Eggman Nega there was a accident that nearly killed him, leaving him afterwards after recovery with strong amnesia about his past.
Or the second option is Eggman (present time) made Silver Since he could not control shadow, He did the next best thing, Plans to make his own ultimate weapon he would be able to control. So he used shadow’s Dna with Amy Rose Dna for making Silver, Since Silver is a full bred Hedgehog, Also the fact it is shown Amy has some psychic intuition/spiritual abilities, but not that strong, I’m guessing eggman at some point saw the potential of a offspring
if the two ever had kids together, The outcome would would be powerful offspring, Since Amy’s psychic ability’s would be increased/enhanced onto the offspring by mixing with shadow chaos energy. Plus he would most likely never die and live long just like Shadow, because of shadow dna. Meaning Shadow would have family that would never leave him from old age. (guess eggmen did something write for the wrong reason but it would benefit shadow.)
unfortunately after Silver was created, He could not wake up as his child like body could not handel the chaos/enchanced psychic abiltiys, His mind was to unstable and dangerous and would mostly kill silver as he would not be able to control the power, and Eggman had no choice but to store him away for safe keeps. until he found salutation to fix the problem. Most likely Shadow would be able to wake Silver up and absorb some of the chaos energy reducing the threat of chaos energy getting out control for silver with his unstable mind due to enhance psychic abiltity mixed with chaos energy, But that would ruin eggman plan for using Silver, Since Shadow wouldn’t let eggman use him and would take silver from him. Years went by and eggman grew older while still keeping tabs on Silver unstable mind/chaos energy. Trying to find a other salutation besides Shadow, But he never got the chance, as he died from old age, and Silver remaind asleep and stored away in one of eggman secret safe base that no one knows about. So Silver managing to sleep away for 200 years and not age(shadow dna) makes more sense, All these years would have calmed down his unstable mind/chaos energy as his body developed to grow to withstand it. Till he was ready to awake on his own without getting overwhelmed by his powers and destroying himself in process.
Also there have been hints, Like Shadow having the role of lancelot and silver having the role of Galahad in sonic in the black knight. Galahad is the son of Sir Lancelot, Meaning Silver would be Shadow Son.
Also there the dragonball Z reference That Shadow would take after Vegeta and Silver would take after Trunks(even time traveling)
Also they have the Same build,and even have the chest hair. and both use chaos energy. also silver bangs style reminds me of black doom in the bigging of shadow the hedgehog. and even after black doom reveals himself, notice those two long spike at his head and the middle spikes pointing upward? doesn’t that remind you of silver spikes, except those two spikes go downward instead of up, and his spike on his forehead are longer then black dooms. plus Amy would have a gene for white, since red and white make pink. also this would be other reference to dragon ball z, where bulma hair was blue but trunks took on lighter color then her, light purple. Unlike taking after his father who was alien from space(shadow is alien) Silver took after amy family side of the gene for white, and not Shadow. Also pink and black make the color grey depending on shade.
The above is prefer theory I like best over the other theory of silver parents. It would benefit Shadow I think best, If Silver is his son, meaning he would live long like shadow. and shadow would have a family that would never die from old age and never leave him like the rest, meaning Immortal just like him.
Because lets face it, Shadow is doomed to outlive everyone, Seeing every one he care about pass on from old age and leave him. would take toll on him.
