PLEASE tell me more about Sonmetadow! Anything at all- headcanons, meta, just rambling about them, anything!!
Sorry this is so late!! But I wanted to answer this for a while.
> Metal gradually develops complicated feelings the longer he’s allowed close proximity with his organic copy. As an AI he learns constantly, but given he’s only ever around Eggman his emotionally intelligence can only go so far. The more he watches, learns from, and mimics Sonic, the more his emotional intelligence grows. And the more he ‘feels’ what Sonic feels (this headcanon is derived from a mix of the OVA movie from the 90s and modern iterations).
> In my au, Metal naturally forms feelings for Shadow because SONIC has feelings for Shadow first. Metal inadvertently mimics these emotions and they develop the longer Sonic’s emotions influence him. In turn he becomes influenced by Shadow’s feelings…it’s a never ending feedback loop, feeding into one another.
> Metal may mimic their emotions to begin with, but as he becomes more advanced, he comes to grasp his own uniquely complicated feelings. He hated Sonic, but it was a hate he was programmed with. When hardwiring meets fallible emotion— which comes out on top? That’s the question. He now can no longer tell if he wants to be his organic copy or if he wants to be WITH him. Sonic has a unique ability to the touch the core of those he empathizes with, and I think if he got past Metal’s hardwiring/if that was ever compromised, Metal has the potential to be the most touched by him.
> He’s still learning, he never ‘finishes’ developing and therefore his feelings are ever evolving, the more self aware he becomes and can begin to pinpoint and predict his own feelings. Sonic is his primary guide in this, while Shadow (who is peak example of holding onto very complicated emotions) kind of learns alongside with him.
> Metal and Shadow bond a lot over things that have been brought up in canon. Shadow has a unique and interesting facet of his character in which he’s shown to consistently show a great empathy and understanding of robots and androids. Metal Sonic, Omega, Emerl, etc… Particularly with Metal, who has a similar dilemma as Omega, in which he’s a tool for the Doctor, like Shadow was. Whereas canonically Omega defected on his own, Shadow is trying to convince Metal to do it. He won’t hesitate to fight Metal, but he would prefer not to, and he’s set aside their necessary opposition to work with Metal in the past, who was even willing to take the chaos emerald from his own body to give Shadow a chance to warp back home. That’s pretty awesome.
> An interesting observation to me is that Shadow and Sonic are both often in opposition from a moral standpoint, they actually both share a goal with Metal. Both of them extend their hands in offering to him, and encourage him to make his own decisions independent of Eggman. And it’s not that Sonic and Shadow even want Metal to be a hero necessarily— even if Metal were to remain an adversary, they just want Metal to come to that decision on his own. Shadow and Sonic both have a strong sense of freedom in their own ways, and encourage others to exercise their own freedom even if it means that person continuing on their own opposing path.
> In a what-if scenario, seeing Sonic and Shadow combine their efforts to free Metal is really fascinating to me. Metal is like Shadow in the sense where it begs the question, can he really learn to love? Is he capable of that particular emotion? Can he grasp what romantic interest really means? He understands as best he can, and is still learning all the while… Yes, while Sonic and Shadow certainly hold a candle for one another by this point in the story, their ‘love’ is considerably complicated. They’re still rivals, after all. Rivals with benefits, I suppose! Except the longer they’re ‘stuck’ together (affectionate) the more they fall into a comfortable push and pull.
They become sort of inadvertently committed (though Sonic continues to see other lovers he’s kept up over the years, Knuckles and Jet), and it probably stems from the fact that Sonic is canonically one of the only (if not the only) people to touch his heart. They are both still guarded in their own ways, and would probably require many lifetimes over and over to fully learn and know the other, and it’s something they enjoy exploring.
The difference is, Shadow has endless time to learn about Metal, but only one lifetime to learn about Sonic. It’s sort of bittersweet, the way Sonic continues to live on through Metal after he’s gone in lots of little ways, but Metal is still his own unique personhood, and Shadow knows better than to think he could use him as a replacement.
Anyway, sorry for this wall of text!! I have a Lot of opinions and feelings on these guys. They’re my OT3 LOL. Please feel free to ask more questions whether it’s regarding my au or just sonmetadow as a concept in general because I have a never ending fountain of thoughts and scenarios on them.
