Dadow Boom AU snippets and ideas while I try to make sense of it! Hooray! :D
Shadow having a soft spot towards kids, especially his own, means Tails is off limits when/if fighting. He dodges all attacks made by the young fox and tries to disarm him without dealing damage. He’ll even step in if Eggman’s attacking and he’s around to help protect Tails.
Silver is around 8 biologically, but 1,000+ chronologically. He’s a little shorter than Tails.
Warning to all villains: Do not, I repeat, DO NOT try to kidnap Silver and hold him hostage against Shadow! He’ll have you begging for the sweet release of death! Kidnapping Silver is a one-way ticket to hell!
Silver gets along with Tails well. Silver doesn’t always understand him, but he tries his best, and Tails appreciates his efforts to understand and honesty when he doesn’t.
Shadow does his best to keep their past under lock and key, but sometimes, Silver will say something that sounds like they were struggling a lot before finding Bygone Island.
Silver’s still practicing his telekinesis, but he’s very good at it! According to Shadow, the edgy looking hedgehog himself was accidentally and quite literally tossed across the room by Silver once. Knuckles and Sonic aren’t allowed to help Shadow teach Silver because they tried making him do all these things that were dangerous.
Shadow is a tired single parent, Sonic and Amy are both working together and fighting each other to make him not a single parent. Shadow doesn’t understand what they see in him. Silver disapproves of them flirting with his dad.
The reason they fought in the first place was because Team Sonic took some strange crystals that Shadow needed, so he went to get them back and it escalated into a fight when they refused.
Eggman once picked Silver up because he thought he was a lost child because Silver was practicing his teleportation skills and showed up at his door. It took Shadow so much not to rip Eggman’s head off when he discovered that Silver was in Eggman’s lair.
Shadow being unbelievably pissed and out for blood if someone dares to lay a hand on his son, partially due to past experiences.
Shadow growing Black Arms features (tail, third eye, wings, bigger claws) when he either needs it or when he just wants to. Silver is completely used to this “monster form” as Sticks put it and will ask to be carried during flights.
Because Silver was created with significantly more hedgehog DNA, the only Black Arms feature he actually has is a longer tail, which is still white. They’re not quite sure where the extra fluff came from, but maybe he’ll grow out of it? (Spoiler alert: He didn’t.)
Here are a few bits I’ve thought of, but might not fit in this AU.
Possible Sticks and Shadow meeting before the rest of the group?? Sticks being an honorary aunt for Silver?? Sticks and Shadow solidarity. Sticks making “old man” jokes towards Shadow. Sticks not asking Shadow much about the whole “half alien” thing or much of his past, just enough to understand the bare minimum and then stop despite her curiosity.
“Hey, Sticks, is your friend single by any chance?” — Sonic
Silver climbing on Shadow, pouncing on him, pulling him, shaking him, whatever it takes to get him up so they can play while the rest of the group watches in horror. Shadow either suddenly waking up from a fake sleep at just the right time and grabbing him, or does the whole “Alright, I’m up, I’m up” thing. Just the group being surprised how patient he is with Silver, I guess.
I don’t usually headcanon Shadow showing signs of age or having old scars because the scars are supposed to heal completely and he doesn’t age, but I think this shall be an exception and give Shadow maybe one or two old scars. Maybe. I haven’t decided yet.
