Who are the likely characters to appear in a 'Deku gets sick' fanfiction?

Sonic himself, of course. And his best friend Tails is very likely to be there. Tails is always by Sonic's side and would surely be there when Sonic is sick.

Obviously, Paul himself is the central character. His brother Reggie might also appear as he could be concerned about Paul's condition and offer support. Ash could be in it too. He might be someone who initially doesn't get along with Paul but then shows compassion because of his illness. And of course, Paul's Pokemon would be there, like his Torterra or Electivire.

Toriel is very likely to be involved. She has a motherly nature and would surely be concerned about Frisk's health. She would probably be at Frisk's bedside, offering comfort and warm food.

There might be a kind - hearted doctor in the 'baby bella gets sick fanfiction'. The doctor would examine Baby Bella carefully, give accurate diagnoses and prescribe the right medicine. Also, her best friend could be a character. Her friend might visit her often and bring her favorite toys or books to make her hospital stay or time of being sick at home more bearable.

One likely antagonist could be a powerful new villain who has the ability to mind - control. This villain might target Deku specifically because of his potential as a hero. Another could be an old enemy of the hero society who sees Deku as a key to their revenge.

Ben himself would definitely be the main character as it's about him being sick. His Grandpa Max is likely to be there, as he is always looking out for Ben. Gwen, his cousin, would also probably be in it, trying to use her magic to help Ben get better or at least understand what's wrong with him.

He might cry a lot. Deku is very emotional, and being cheated on would be a very painful experience for him. He could also get angry, which is rare for him, but this situation would be so unjust that he might not be able to hold it in. He'd probably start to question his self - worth too, thinking that there was something wrong with him that made his partner cheat.

Obviously, his brothers are very important. Donatello would be crucial as he could try to diagnose Leo's illness. Raph would be there to provide protection and strength if any threats come while Leo is vulnerable. Mikey would be the emotional support, trying to keep Leo's spirits up.

Obviously, Deku would be the main character since it's about being reborn as him. But other characters like All Might are also likely to be important. All Might was a huge influence on Deku in the original story, and in the fanfiction, he could still play a crucial role in mentoring the reborn Deku.

In addition to the main ones like Jibanyan and Whisper, there could be Venoct. He's a cool and somewhat mysterious Yo - Kai. He might initially seem like a threat but then turn out to be an ally to Katie. There's also Robonyan. As a robotic Yo - Kai, he could be helping Katie upgrade her Yo - Kai Watch or use some of his high - tech abilities to fight against bad Yo - Kai. And then there's Komajiro, Komasan's little brother. He could be tagging along with Komasan and getting into all sorts of cute and comical situations with Katie.
