If Hermione is given a love potion in fanfiction, it could lead to all sorts of chaos. Her friends would likely notice the sudden change in her behavior. They might first be confused, and then as they figure out it's a love potion, they'd try to find an antidote. Ron would probably be especially affected by seeing Hermione act so differently towards someone else.
In the fanfiction, Hermione might face a lot of internal conflict. The lust potion could make her have unexpected feelings towards someone. Maybe she'll struggle to resist the effects of the potion and try to maintain her self - control. It could also lead to some interesting interactions with other characters as they notice her changed behavior.
If Naruto drinks a love potion in fanfiction, it could potentially disrupt the relationships he already has. His friends might be really confused by his new behavior. Maybe he'll start ignoring his long - time friends like Sasuke or Sakura in favor of the person he's under the influence of the love potion for. And this could create a lot of drama within the group, as they try to figure out what's wrong with Naruto and how to fix it.
In such a fanfiction, one consequence could be that Hermione might struggle with her own emotions. She's a very rational character usually, but the lust potion could make her act out of character. She might find herself attracted to someone she wouldn't normally be interested in, leading to confusion and inner turmoil.
In the fanfiction world, if Snape was deaged to 16 by a potion, he might have a whole new set of challenges. Firstly, his relationships would change. He'd probably have a different dynamic with his peers at Hogwarts. His knowledge and skills would still be there, but his physical and emotional state would be that of a 16 - year - old. He might struggle to be taken seriously by those who knew him as an adult, and his interactions with students could become more complex as he'd be closer in age to them.
In a Hermione potion accident fanfic, she might accidentally create a potion that causes strange transformations. For example, she could turn into an animal or have her appearance altered in a unique way. This could lead to all sorts of adventures as she tries to reverse the effects. Her friends, like Harry and Ron, would likely be involved in helping her figure out what went wrong and how to fix it.
A great plot twist could be that the love potion Hermione is exposed to actually has a secondary effect. While it initially makes her seem infatuated, it's secretly stealing her magic. As she becomes more and more 'in love', her powers start to wane. Her friends notice the change in her abilities and suspect foul play. They then have to race against time to find out what's really going on and reverse the effects before she loses all her magic.
It could give her unexpected powers or abilities, changing her role in the story completely.
Maybe Captain America accidentally drinks a love potion and falls for a civilian. This could put the civilian in danger as his enemies might target her to get to him. So, he has to protect her while also trying to figure out how to reverse the effects of the potion.
In a Johnny Test love potion fanfiction, the love potion could be part of a science fair project. Johnny's intention was to create a potion that would make people like each other more in general. But when he tests it on himself, he falls in love with the concept of time travel (because he was thinking about it right before taking the potion). So he starts trying to build time - travel machines to be closer to what he loves, and his family has to stop him before he causes a time - related disaster.
A simple scenario could be that a love potion is slipped into Hannibal's drink at a social gathering. He then starts to have strong feelings for someone he previously only had a professional relationship with. This changes the dynamics between them completely, leading to awkward and intense situations as they both try to figure out what's going on.
