In a Pokemon fanfic, when Pikachu gets sick, Ash is likely to be in a panic. He's so close to Pikachu that he'd be constantly checking on it. Misty could be the more level - headed one, perhaps suggesting that they take Pikachu to a more experienced healer in a nearby town. Brock, with his knowledge of Pokemon care, would be looking for natural remedies in the area. The other Pokemon in the team might also show their concern. For instance, Bulbasaur could use its healing moves to try and make Pikachu feel a bit better, while Charmander could keep Pikachu warm with its flame.
The reactions of the other characters when Pikachu gets sick in a Pokemon fanfic can be quite diverse. Ash, of course, is the most affected. He'd be like a mother hen, fussing over Pikachu. His whole world would seem to revolve around getting Pikachu well again. Misty would be sympathetic and use her own knowledge of Pokemon to offer help. She might remember something she saw her sisters do when their Pokemon were sick. Brock would immediately spring into action, thinking about what kind of food would be best for a sick Pikachu. The other Pokemon in the group would also show their love for Pikachu. They might huddle around it to show support or use their own unique abilities to try and comfort it. All in all, the sick Pikachu would bring out the best in the characters' caring and problem - solving sides.
Ash would be extremely worried. He'd do everything he could to make Pikachu feel better, like staying up all night to take care of it. Misty might offer some practical advice, like making sure Pikachu stays warm. Brock would probably be ready to cook some special food for Pikachu to help it regain its strength.
In a Pokemon fanfic when Pikachu gets sick, it might become very weak and unable to battle. Ash would probably be really worried and take it to a Pokemon Center right away. The Nurse Joy there would use her skills and Pokemon medicine to try and heal Pikachu.
The teachers, especially Aizawa, would also be worried. Aizawa might give Bakugou special permission to skip classes or training until he's recovered. He'd also keep an eye on Bakugou's progress and make sure he's taking care of himself.
Scott would probably be very protective. He'd do everything he can to find out what's wrong with Liam and how to cure him. Stiles might use his detective skills to figure out the cause. He'd be running around, asking questions and looking for clues.
The other characters would be very worried. Edmund, for instance, would probably feel guilty as he might think it was his fault in some way. He'd be constantly by her side, trying to make her feel better. Peter would take on a more responsible role, looking for ways to get help. He might search for a magical cure or someone who could heal Lucy.
The other Pokemon in the Pokemon Center where Pikachu is usually treated would be very frightened. Nurse Joy would be at a loss as to what to do, as she has never seen Pikachu act this way. Professor Oak would be extremely concerned and would start researching immediately to find out what could have caused this sudden change in Pikachu. Team Rocket, on the other hand, might initially see this as an opportunity to capture Pikachu more easily, but they would soon realize that an evil Pikachu is far more dangerous than they expected and might end up getting in over their heads.
Leo would likely take charge. He'd be calm on the outside but worried inside. He'd make sure Donnie gets proper rest and tries to organize the others to help. Raph might be a bit gruff at first, but he'd actually be really concerned. He might offer to get supplies or guard Donnie while he sleeps. Mikey would be the most emotional. He'd probably be constantly by Donnie's side, trying to tell him jokes to make him feel better.
The other characters' reactions could vary. Some of the more hot - headed gang members might initially be impatient about Ponyboy being sick and not being able to participate in their activities. But as they see how serious it is, they would come around. The Socs, if they knew, might not care much on the surface, but there could be a few who feel a bit of sympathy, especially if they start to see Ponyboy as more than just an 'outsider'. And the girls in the story, if there are any, would probably be very motherly and bring things like soup and warm blankets for Ponyboy.
Abby would be all over Tony, bringing him some of her special energy drinks (even though they might not be the best for a sick person). She'd also use her skills to try and find out what's wrong with him in a more scientific way. Ducky would of course offer his medical expertise, and might even tell some long - winded stories while examining Tony to try and keep his spirits up.
Zuma would probably offer to keep Skye company near the water, as he loves the beach. He could tell her funny stories about his underwater adventures to make her laugh. And Ryder would be in charge of making sure Skye gets proper medical attention. He'd be constantly checking on her and making sure she has everything she needs.
Annabeth would probably be very worried and take charge. She'd start researching immediately, looking through books in the camp library to find a cure. Grover would be constantly by Percy's side, using his nature - related powers to try and make Percy more comfortable, like bringing in fresh air and plants to help him feel better.
