Sonic would probably be very shocked at first. He trusts Amy, so her betrayal would be unexpected. He might initially try to talk to her to understand why she did it.
In this kind of fanfiction, it might be that Amy thinks Sonic has been hiding secrets from her. These secrets could be something she believes are harmful to their friends or the world they live in. So she decides to betray Sonic in order to protect everyone else. Sonic would then be left confused and hurt, having to figure out how to fix the situation.
Well, Sonic is a hero at heart. So when Amy gets hurt, he would first assess the situation calmly, but inside he'd be worried. He'd make sure she was stable and then look for the cause of her injury. If it was an enemy, he'd go after them. But he'd also be very gentle with Amy, talking to her softly and reassuring her that she'll be okay. He'd do whatever it takes to see her back on her feet again, like finding special herbs or items that could speed up her healing process.
Positive Sonic fanfiction could be about Sonic mentoring the younger characters like Tails and teaching them important life lessons. Or it could be about Sonic and his friends having to solve a mystery in their world, like a strange disappearance of an important item or character. Fanfictions that show the characters growing and evolving in positive ways, such as Amy becoming more confident in her own abilities, are also excellent alternatives to inappropriate fanfiction themes.
One common theme is trust. When Sonic is betrayed, it shatters the trust he had in his friends or allies. This often leads to a journey of rebuilding that trust or finding new trustworthy companions.
Well, in the official Sonic world, this kind of plot would be highly uncharacteristic. However, in the vast realm of fanfiction, there might be some out there, but it's very hard to find one that is not adult - themed. Since Sonic is a well - known and family - friendly franchise, most proper fan works focus on adventure, friendship, etc., rather than this sort of inappropriate content.
I'm not sure if there is a specific 'Sonic gets Amy pregnant' fanfic. Fanfic topics can vary widely, and while there are many Sonic - related fanfics, such a controversial and non - canon plot like this might not be as common. It also depends on different fanfic platforms and their content policies.
One popular 'sonic gets betrayed fanfiction' might be 'Sonic's False Friends' where Sonic is wrongly accused by his comrades due to a misunderstanding created by Dr. Eggman's devious plan. In this fic, Sonic has to fight not only his real enemies but also the distrust of his friends.
One possible storyline could be that Amy gets hurt while trying to protect Sonic from an enemy. Maybe she jumps in front of a powerful attack meant for Sonic. Another could be that she gets injured during a dangerous adventure in a new, uncharted zone. For example, she might fall into a hidden trap.
In the fanfiction, Sonic's jealousy could lead to him realizing his true feelings for Amy. Maybe he's always seen her as just a friend, but when he sees her with someone else in the story, he starts to feel a pang of jealousy. This could then turn into a romantic pursuit of Amy, where he tries to win her over by being more attentive and less dismissive of her feelings.
