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.

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.

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.

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.

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.

Sasuke would be a likely character to appear. Since he and Naruto have a deep connection, Sasuke might cross paths with Naruto during his wanderings, either as an ally or an antagonist depending on the plot.

The main characters would surely include Deku. Then there could be his classmates from U.A. High. Iida might be one of them, who could have a very formal reaction to Deku's new haircut. And then there could be a new character, like a street - artist who is inspired by Deku's new look and starts to create art based on him.

Obviously Elsa herself would be one of the main characters since she is the one getting sick. Anna would also be a main character as she would be very concerned about Elsa's condition and would do everything she can to help. Olaf could also play an important role, using his cheerfulness to try to make Elsa feel better.

Obviously, Bendy would be one of the main characters since he's the one getting sick. His friends like Boris and Alice would also be main characters as they would likely be involved in taking care of him or finding a cure.

Mario would most likely be a main character too. He's Luigi's brother, so he'd be there to take care of him or at least be really worried about him. Princess Peach could also be a main character. She might visit Luigi when he's sick and bring some kind of magical item that could potentially help him get better.
