His friends would likely be very concerned. Tails, for instance, would probably immediately start working on some kind of device to help Sonic regain his sight or at least make his life easier. He might create a pair of goggles with special sensors that can detect obstacles. Amy would be very emotional and would offer a great deal of emotional support, constantly staying by Sonic's side to make sure he's okay. Knuckles might be a bit more practical, offering to train Sonic in new ways of fighting that don't rely on sight so much.
The long - term consequence might be that Sonic has to completely redefine his role in his world. Instead of being the front - line hero who dashes into danger first, he might become more of a strategist, using his brain and his remaining senses to plan attacks. His relationships with his enemies could also change. Some enemies might see his blindness as a weakness and target him more, while others might respect his new - found vulnerability and leave him alone. And his friends would have to take on more of a protective role, which could strain some of his relationships as he might not like being 'protected' all the time.
Well, in a Sonic gets blinded fanfiction, the plot might involve Sonic getting blinded by a strange energy blast. His friends are distraught, but Sonic remains determined. He starts training with Knuckles to enhance his other senses, especially his sense of touch and hearing. Meanwhile, they investigate the source of the blast. As Sonic adjusts, he becomes an inspiration to others in his world, and in the end, they might find a way to reverse the blinding or Sonic may simply accept his new way of life and continue to be a hero.
Tails would probably be very helpful. He'd use his intelligence to make sure Amy has a comfortable pregnancy, like creating special devices for her. Knuckles might be a bit awkward at first but would ultimately be very protective. He'd stand guard to make sure no harm comes to Amy and the unborn baby.
I'm not sure if there are extremely well - known ones specifically about this topic. However, in the Sonic fanfiction community, there could be some hidden gems. It's possible that some independent writers have created great stories around Sonic getting blinded, but they may not have gained widespread mainstream attention yet.
Their friends would be really excited. Tails would probably be the first one to offer his help. He could use his mechanical skills to build baby - friendly gadgets. Knuckles would be a bit more gruff but still happy. He might offer to train the baby in self - defense when it grows up. Cream and Cheese would bring little presents for the baby, like cute toys or delicious Chao fruits.
Their friends' reactions would vary. Tails would be enthusiastic and start thinking of all the ways he could help. He could create little gadgets for the baby, like a mini - sonic - speed - training - device when it gets older. Knuckles would be more of a protector. He'd see it as his duty to make sure the baby is safe, especially since Sonic is his friend. Rouge would be the fun auntie type. She'd bring stylish baby clothes and tell the baby all kinds of exciting stories from her travels. And the Chaotix might be a bit clumsy but well - intentioned in their attempts to interact with the baby.
Tails would probably be really excited. He'd be the helpful uncle, always ready to use his mechanical skills to make cool toys for the baby. Knuckles might be a bit more gruff at first, but deep down he'd be protective of the little one. Amy would be over the moon and would constantly offer to babysit so she could play with the baby.
Their friends would likely be overjoyed. Happy for the couple and excited to be part of the wedding. For example, Natsu might be a bit rowdy but full of genuine happiness for Rogue, while Erza would be more composed and offer practical help with the wedding preparations. Levy would probably be helping Lucy pick out the perfect dress and gushing about how romantic it all is.
Sonic would be devastated. He and Tails are like brothers. Sonic would likely go into a rage and vow to avenge Tails' death. He would immediately start hunting down whoever or whatever was responsible. Amy would be heartbroken as well. She would probably be the one to try to comfort Sonic while also being deeply sad herself. Knuckles would be angry and ready to fight alongside Sonic to seek justice for Tails.
Star's friends would likely be a mix of helpful and confused. Since Star is from another dimension, her friends might not be entirely sure how to handle it. But overall, they would probably try their best to make her feel normal. For example, they could plan a girls' night in for Star and the female friends, with movies, junk food, and lots of girl talk.
